We examined the effects of repeated sprint training (RST) session volume on acute physiological, neuromuscular, perceptual and performance outcomes. In a randomised, counterbalanced, and crossover design, 14 healthy and trained male and female athletes (age: 23 ± 3 years) completed two sets of 10 × 40 m (10 × 40), 5 × 40 m (5 × 40), 10 × 20 m (10 × 20) and 5 × 20 m (5 × 20) sprints with 30 s rest between repetitions and 3 min rest between sets for all protocols. Average and peak heart rate, average oxygen consumption (VO2), time >90% of maximal oxygen consumption (VO2max), differential ratings of perceived exertion (RPE), session‐RPE training load (sRPE‐TL), percentage sprint decrement (Sdec), acceleration load and distance >90% of maximal sprint speed were recorded during each session. Neuromuscular performance (i.e. countermovement jump, lower‐limb stiffness and isometric hamstring strength) were measured post‐session, 24 h, and 48 h and compared to pre‐session. A univariate analysis of variance was used to compare within‐ and between‐protocol differences. To aid data interpretation, all effects were expressed as an effect size and accompanied by probability values (pMET). The 10 × 40 protocol induced the greatest training load compared to all other protocols (pMET < 0.05), including moderate to very large differences in breathlessness RPE, large differences in Sdec and time >90% VO2max and very large differences in sRPE‐TL. The 5 × 20 protocol induced the lowest training load compared to all other protocols (pMET < 0.05), including moderate to large differences in sRPE‐TL and leg muscle RPE. Heart rate, VO2, sRPE‐TL, leg muscle RPE and Sdec were similar between 5 × 40 and 10 × 20 (pMET < 0.05), but the acceleration load was greater for 10 × 20 when compared to 5 × 40 (pMET < 0.001), and this difference was large. Changes in neuromuscular performance across all timepoints and all protocols were unclear. Larger session volumes increase the demands of RST and by manipulating volume, sprint distance and the number of repetitions, practitioners can alter the internal and external training load. Highlights: The 10 × 40 protocol (i.e. 800 m volume) induced the greatest physiological and perceptual demands, which was demonstrated by a session average heart rate and VO2 of 89% ± 3% and 72% ± 8% of max, respectively, whereas differential RPE were rated hard to very hard on average.Performing 10 repetitions did not substantially increase the average VO2 demands when sprint distance was matched (e.g. 10 × 40 vs. 5 × 40). Rather than prescribing high repetition protocols, practitioners are encouraged to increase sprint distance if a greater aerobic stimulus is desired.There were no differences in the heart rate and VO2 recovery between the 2nd and 3rd minute of inter‐set recovery. Therefore, to reduce session duration while providing adequate recovery of cardiorespiratory function, 2‐min passive rest periods can be prescribed. [ABSTRACT FROM AUTHOR]

The Nordic Hamstring Exercise (NHE) improves the strength of the hamstring muscles, as well as prevents and rehabilitates the injuries of said muscles. However, the eccentric demand of NHE may influence the athlete's performance, making compliance with these programmes difficult. The aim is to analyse the acute impact on sprint performance after the passing of 24, 48, and 72 hours respectively since an NHE-based session (4 sets of 10 repetitions) had taken place. Participants were randomly divided into an experimental group (EG) (n = 12 male participants) who carried out an NHE session and a measurement of their 30 m sprint performance in each of the three subsequent days, and a control group (CG) (n = 12 male participants) who did not take part in the NHE session. The results show a significant reduction of maximum power within 24 hours (t = 3.57, d = 0.22, P <.0273) as well of the production of high speed horizontal force up to after 48 hours (t = 4.82, d = 0.22, P <.0001) in the EG. These results may suggest separating weekly NHE sessions from competition or demanding training in which sprint performance should not be affected by at least 72 hours. [ABSTRACT FROM AUTHOR]

Microcycles are fundamental structures for training prescription and load management, helping to optimise training effects and performance. This study quantified external and internal loads of Italian Serie A youth soccer players across competitive weeks and their periodisation within microcycles. Data were collected from 90 players belonging to four age groups (under-19, -17, -16, -15) across a season. Methods of monitoring external [duration and global navigation satellite systems (GNSS)] and internal load [heart rate (HR) and rating of perceived exertion (RPE)] were employed. Linear mixed models determined differences in training loads across age groups, training days and player positions. Under-19 and under-17 players trained five times per week, while younger players trained four times. Late-stage academy players (under-19 and -17) demonstrated higher weekly accumulated external and sRPE training load compared to their younger counterparts (p < 0.05 between groups). Weekly accumulated HR internal loads were higher in under-15 players (p < 0.05 between groups). Marked fluctuations of daily load were observed across microcycles in under-19 and under-17 groups (p < 0.05 between days). These findings highlight progressive increases in training load throughout the development pathway, with late-stage academy players training with higher frequency, volume and marked periodisation compared to younger players.

Strength and conditioning (S&C) interventions for golfers consistently demonstrate improvements in performance metrics such as clubhead speed. Golfers typically employ Professional Golfers' Association (PGA) coaches to support technical and tactical development. These coaches need to ensure golfers balance S&C training alongside competitions and technical golf practise, although no empirical data exist that demonstrates how this integration occurs practically. This study aimed to investigate the perceptions and practises of PGA Professional golf coaches and how S&C is integrated into the golf year. Forty-three (male = 35; female = 8) PGA coaches completed a mixed-methods survey with questions on themes such as coaching approach, perceptions of S&C, annual planning and goal setting. Results show that formal planning processes are highly variable or absent. The majority (n = 29; 70.7%) of PGA coaches stated they worked with an S&C coach and see the role of the S&C coach to support golfers with their input. However, when planning the season, 63.4% (n = 26) of coaches do so without input from the S&C coach. These and other related disconnects between desire for S&C intervention and inclusion of the S&C coach in planning processes were evident throughout survey responses. There may be subsequent risks of conflict or misunderstanding between PGA coach, S&C coach and golfer. It is recommended golf coaches, golfers and S&C coaches work collaboratively as a multidisciplinary support team to ensure coordinated golfer support is obtained. [ABSTRACT FROM AUTHOR]

Background The importance of nutrition in optimizing the health and performance of professional soccer players has been well established. Despite published practical recommendations for the dietary requirements for professional soccer players, many players fail to meet these guidelines. Thus, the primary purpose of this study was to assess the impact of targeted nutritional education and behavior change interventions on dietary intake in professional football players. Additionally, previous research within this population has reported elevations in resting metabolic rate (RMR) following match-play. Therefore, a further aim of this study was to examine whether any changes in dietary intake would influence RMR following match-play.Methods Twenty players from the professional development phase in an English Premier League club (age: 18.4 ± 1.0 years; body mass: 76.1 ± 6.0 kg; stature: 1.80 ± 0.07 m) were randomly assigned to an “Intervention” (INT) group (n = 10), who received numerous nutritional education and behavior change interventions, or a “Control” (CON) group (n = 10), who received no nutrition support. Dietary intake was assessed daily throughout the match-week (Match Day (MD)-2, MD-1, MD, MD + 1, and MD + 2), whilst RMR was assessed on MD-1, MD + 1, and MD + 2. Statistical analyses on the intervention effects on dietary intake and RMR were carried out using a two factor (group and day) analysis of variance (ANOVA) with a subsequent Bonferroni post-hoc test.Results Mean energy (3393 ± 852 vs. 2572 ± 577 kcal · day−1) and CHO (5.36 ± 1.9 vs. 3.47 ± 1.1 g · kg−1 BW · day−1) intake was significantly higher (p

Dance research should consider time points within a season that may be associated with injury, and report on weekly dance training loads. The current study aimed to analyse injuries within each semester and participant, monitor load, mood and stress within one semester, and calculate compliance with monitoring in a tertiary dance training cohort. The dance training program that participants are drawn from is a six-semester, three-year undergraduate course, training in ballet and contemporary dance. A better understanding of injury in dance may further refine load management and injury prevention strategies. Fourteen tertiary dance students consented to participate. A medical attention injury definition was used. Weekly injury rate ratios within each 14-week semester were calculated. Participants completed ratings of perceived exertion , and mood and stress questionnaires across one semester. Injuries were significantly increased for Week 5, Semester 1; Week 2, Semester 2; and Week 1, Semester 3, and 4. Spikes in load coincided with injury spikes, as observed visually on a line graph. Certain weeks in proximity to a change in training schedule had increased injury. Applying training principles in response to monitoring, specifically to return to dance after a holiday period, may aid in reducing injuries at this time requiring further investigation.

Background. Against the background of everincreasing interest in the Viking Age in the world scientific community, the results of the research by scientists from different countries are being updated. In this connection, the question of distinguishing phases within this relatively long period of history, which remains debatable in domestic and foreign historiography, inevitably arises. The purpose of the work is to analyse and compare approaches to the problem of periodisation of the Viking Age in England based on the materials of English-language authors, their comparison with the periodisation established in the domestic historiography. Materials and methods. The sources for the present study were the published scientific works of English-language historians of the late 20th – early 21st centuries, in which the Viking Age in England is considered and attention is paid to the issue of its periodisation. When considering this problem, the methods of historiographical analysis are used: comparative-historical, systematic, historism. Results. It was possible to identify the main approaches to the periodisation of the Viking Age in England in modern English-language historiography, to determine their characteristic features, to compare and contrast them with the periodisation accepted in the domestic historiography. Conclusions. The presence of different approaches to the periodisation of the Viking Age among English-language historians is explained by the development of scientific interest in the problem as a whole, as well as by the increase in the source base. These circumstances actualize discussions and are the basis for new interpretations of the chronological framework of the period under consideration. Differences in the nationality of the authors, the number of available sources, the degree of development of regional history determine the existence of several approaches to the periodisation of the Viking Age in England among English-language authors.

It is common these days to lament the recession of democracy around the world. The way scholars address the issue of democratic backsliding shows that there is a significant gap between the expectation about democracy's anticipated course of development and the current state of affairs. This article argues that the expectation that democracy would consolidate over time was produced by the progress narrative of democratic governance discourses. Drawing on narratology, it conducts a discourse analysis to demonstrate that today's dismay about the recession of democracy is due to an unwarranted expectation that was created by the progress narrative of democratic governance discourses. It focuses on the periodisation of history in the construction of these discourses and investigates how scholars used the Cold War – post-Cold War dichotomy to create a progress narrative.

OpenAI's Chat Generative Pre-trained Transformer (ChatGPT) technology enables conversational interactions with applications across various fields, including sport. Here, ChatGPT's proficiency in designing a 12-week resistance training programme, following specific prompts, was investigated. GPT3.5 and GPT4.0 versions were requested to design 12-week resistance training programmes for male and female hypothetical subjects (20-years-old, no injury, and 'intermediate' resistance training experience). Subsequently, GPT4.0 was requested to design an 'advanced' training programme for the same profiles. The proposed training programmes were compared with established guidelines and literature (e.g., National Strength and Conditioning Association textbook), and discussed. ChatGPT suggested 12-week training programmes comprising three, 4-week phases, each with different objectives (e.g., hypertrophy/strength). GPT3.5 proposed a weekly frequency of ~3 sessions, load intensity of 70-85% of one repetition-maximum, repetition range of 4-8 (2-4 sets), and tempo of 2/0/2 (eccentric/pause/concentric/'pause'). GPT4.0 proposed intermediate- and advanced programme, with a frequency of 5 or 4 sessions, 60-90% or 70-95% intensity, 3-5 sets or 3-6 sets, 5-12 or 3-12 repetitions, respectively. GPT3.5 proposed rest intervals of 90-120 s, and exercise tempo of 2/0/2. GPT4.0 proposed 60-180 (intermediate) or 60-300 s (advanced), with exercise tempo of 2/1/2 for intermediates, and 3/0/1/0, 2/0/1/0, and 1/0/1/0 for advanced programmes. All derived programmes were objectively similar regardless of sex. ChatGPT generated training programmes which likely require additional fine-tuning before application. GPT4.0 synthesised more information than GPT3.5 in response to the prompt, and demonstrated recognition awareness of training experience (intermediate vs advanced). ChatGPT may serve as a complementary tool for writing 'draft' programme, but likely requires human expertise to maximise training programme effectiveness. [ABSTRACT FROM AUTHOR]

Scientific knowledge of the training of elite athletic sprinters is limited, and much of their training relies on the intuition and expertise of experienced coaches. Therefore, the objective of this study is to provide an overview of the training practices employed by elite Spanish sprint coaches. A descriptive analysis was conducted using customised questionnaires from 14 sprint-specialised coaches who volunteered to participate. These coaches used both traditional (50%) and block periodisation (50%). Many coaches (78.6%) divided training into three phases within each of the two macrocycles. Additionally, all coaches incorporated a tapering phase of varying durations. During the general preparation phase, the focus was on strength training (78.6%) and tempo training (85.7%). In the specific preparation phase, priority was strength-speed (92.9%) and speed-endurance (100%). The competitive phase emphasised speed-strength (100%), acceleration and maximal velocity (92.9%). Coaches incorporated technique work prior to sprint sessions (100%) and conducted specific monitoring/testing sessions (78.6%). Most coaches also monitored indicators of fatigue (78.6%) and recovery parameters (100%). In conclusion, elite Spanish sprint coaches employ relatively similar strength and sprint training methods throughout the season, gradually shifting the focus towards competition specificity. However, these coaches implement different macro-periodisation models. [ABSTRACT FROM AUTHOR]

The pre-season plays a crucial role in the preparation of professional football players, as it allows for an extensive focus on training sessions compared to the more congested schedules during the in-season period, especially in professional football leagues. This study aimed to describe the workload during a 6-week pre-season in Belgian professional football players and to analyse and compare the workloads for players in each microcycle according to several variables of external workload (e.g., distance covered at some velocities). Seventeen male Belgian professional football players competing in the second division of the Belgian league system participated in the study. Throughout the 6 weeks, the players were closely monitored during both training sessions and friendly matches using Global Positioning System (GPS) devices. Several parameters, including total distance covered and distance at different velocities, were recorded. Accelerating and decelerating distances, as well as the number of sprints, were also captured. Statistical analysis was based on a repeated measures ANOVA, percentage dynamics, and effect size calculations. The results obtained showed a progressive increase in the distance travelled at different intensities from week 1 (i.e., lower values) to week 3 (i.e., higher values), with reductions in these values in week 6, prior to the start of the official competition. Similarly, the peak of accelerations and decelerations were observed in week 2 and week 3, with decrements at the end of the pre-season period. This comprehensive investigation attempts to shed light on the effects and dynamic changes in external workload during the crucial pre-season, contributing valuable insights for coaches and practitioners in football conditioning and training programs, especially concerning optimal preparation for the beginning of the league's season.

The management of training load in youth team-sport athletes is important. There is, however, a lack of research on practitioners' perceptions and understandings of managing training load during this period and what this means in terms of maturational status and injury risk. This study aimed to investigate academy football practitioners' perceptions and understanding of training load, maturation and injury risk in young male footballers. Coaches, sports scientists, medical staff and key stakeholders from a professional football club academy in England participated in focus groups investigating their understanding and perceptions of training load, maturation and injury risk. A qualitative descriptive methodology utilising framework analysis was used to capture and better understand participants' views. Findings revealed that practitioners consider managing training load during adolescence to be comprised of, and mediated by, three key elements: club philosophy, factors inside the club's control (periodisation strategy; staff member practice), and factors outside the club's control (life load; growth and maturation). This study is an important addition to the current literature on managing injuries through the growth spurt by investigating how different stakeholders perceive training load, maturation and potential strategies to mitigate risk.

Standards are pivotal for generating the evidence required to manage players in professional sport environments like rugby union. Resultantly, using a three-step qualitative approach, this study aimed to formulate a consensus as a subjective standard for evidence generation pertaining to player management. The consensus statement intended to identify evidence on peaks/troughs in player external training loads using Global Positioning System (GPS)-based information in the High-Performance Unit (HPU) of a Gallagher Premiership rugby union club. Initially, a systematic review adhering to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) framework was conducted to unravel the factors considered (literature-based cues) when identifying peaks/troughs in player external training loads using GPS information. Next, thematic analysis conducted on the data obtained from 7 semi-structured interviews with HPU staff highlighted that they consider 6 factors with 38 elements (practitioner-based cues) during player external training load management. Thereafter, guided by the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument and by utilising selected elements representing 4/6 factors (healthy player, GPS information, longitudinal durations and practitioner judgements on information), a consensus among practitioners for identifying peaks/troughs in player external training loads was developed with the participation of five HPU members using the nominal group technique (NGT). Practitioners reached an agreement with regard to 12 indicators to subjectively identify peaks/troughs in player external training loads within the considered environment. [ABSTRACT FROM AUTHOR]

Background: There are no published data on the training-load magnitude or distribution in elite international-level boxers preparing for a major competition nor on the training load’s relationship with objective and subjective training markers. Methods: Twelve elite boxers (eight males and four females) preparing for the 2018 Commonwealth Games were monitored during training for 12 weeks. The training load (TL), change in creatine kinase (ΔCK), and wellness variables were measured daily but were amalgamated into average weekly values over the 12-week period for weekly comparisons. The relationships between the TL, ΔCK, and wellness variables were also assessed. Results: The significant (p < 0.001) main effects of the week with large and moderate effect sizes were noted for the TL and ΔCK, respectively, with weeks 9 and 12 in the competition-specific and taper phases showing the greatest differences, respectively. For wellness, only the muscle condition showed a significant change over time (p < 0.001). There were significant (p < 0.05) small–moderate correlations between the TL, ΔCK, and wellness variables. Conclusions: This is the first study to describe the weekly training loads and responses to training of elite international boxers across a 12-week pre-competition training period in preparation for a major competition. The findings within this study report that elite international boxers have high chronic training loads that change between training blocks to put emphasis on different qualities. Monitoring the indirect muscle damage through CK may provide further information on the internal training responses in boxers.

The purpose of the article is implementation into scientific use the proposed time limits and names of creative path's periods of artist Mykola Hlushchenko (1901-1977). Based on analysis of well-known facts of his life and creativity, studies of artist's artistic heritage from 1940s-1970s artworks collection of Dnipro Art Museum. The research methodology is based on the methods of art-stylistic and comparative analysis of Mykola Hlushchenko's paintings, considered in art-historical and cultural-historical aspects. The scientific novelty of research consists in scientific 1940s- 1970s creativity periods determination of M. Hlushchenko based on research of Dnipro Art Museum collection and additional attribution of individual painting artworks according to the proposed stages. Conclusions. Based on the analysis of Mykola Hlushchenko's paintings from Dnipro Art Museum collection and study in accounting fund documentation of the institution, considering biographical and autobiographical information, socio-political and historical-cultural context, we proposed a refined periodisation of the artist's work. Division of creative stages of M. Hlushchenko for more detailed periods will allow a more thorough and deeper analysis of the well-known today artist's creative heritage. Using the example of Dnipro Art Museum collection, we concluded that a certain number of works in the museum collections of Ukraine require additional attribution. In addition, the creative heritage of outstanding Ukrainian artist Mykola Hlushchenko remains insufficiently studied and requires comprehensive research. [ABSTRACT FROM AUTHOR]

Purpose The relationship between strength, power, and sports performance may have long-term effects on the development pathways of youth athletes. This study systematically reviewed the current evidence of strength and conditioning interventions among youngsters in competitive sports. Methods The research was conducted following the Preferred Reporting Items for Systematic and Meta-Analyses (PRISMA) 2020 guidelines. Results A total of 415 articles were identified, and 20 remained for analysis. All studies reported resistance training (RT) and/or plyometric training (PT) interventions as beneficial to improving youngsters’ overall physical fitness. The lower-body explosive strength, speed, and agility improvements were more evident in training plans that combined heavy RT and PT programs. The training frequency of twice a week was sufficient to induce strength gains. The results indicate that strength and conditioning programs positively influence sport-specific skills performance. Conclusions PT and RT should not be implemented as single exercise interventions but as complementary programs to optimise physical and game performance. This study contributes to creating awareness among sports agents and coaches for integrating planned strength and conditioning programs with qualified instruction at least two times per week to improve young athletes’ physical development.

Max Dvořák, one of the pilasters of the Viennese school of art history, is nowadays widely known for the works of his final years as well as for writings on monument conservation. Through a reconstruction of the historical and academic context and a brief presentation of Dvořák’s studies on the transition period from the fourteenth to the fifteenth century, the author aims to show that the Bohemian scholar made an important contribution to the art historical debate of the time, for which he is hardly appreciated today. This article examines a selection of Dvořák’s early writings from the first decade of the twenthieth century. In particular, the habilitation thesis Das Rätsel der Kunst der Brüder van Eyck (The Enigma of the Art of the Van Eyck Brothers, 1903) is consulted. While many scholars claim that there is a wide gap between his older works and those from the last years of his life, as stated by his former students Karl M. Swoboda and Johannes Wilde in the preface to Kunstgeschichte als Geistesgeschichte (1924), it is argued here that Dvořák’s point of view already presents the basic elements of his more mature conclusions at the beginning of his academic career. Likewise, it is reflected on the fact that Dvořák made a remarkable contribution to a new consideration of the transitional period between the late Middle Ages and the Renaissance, among other workd, with his Enigma, but that this is today attributed not to him but to the cultural historian Johan Huizinga and his work Autumn of the Middle Ages (1919).

The term najnowsze dzieje polszczyzny / najnowsze dzieje języka polskiego (the latest history of the Polish language) has been in use since the late 1970s and the early 1980s. It has brought problems concerning the chronologisation and internal periodisation of that period in the history of the Polish language. The participants of the discourse, which has continued since the early 1990s, include linguists such as Antoni Furdal, Krystyna Kleszczowa, Stanisław Borawski, Stanisław Dubisz, Irena Bajerowa, Ewa Woźniak. Their publications clearly evidence the need for distinguishing the period in the periodisation of the Polish language, while differing as to its specific timeframe, distinction criteria, and internal periodisation. This study aims to compile the data, present the history of the discourse, and make a summary proposal. [ABSTRACT FROM AUTHOR]

An introduction to articles published within the issue is presented, including one which explored how Tudor writers reflect upon writings from the late medieval past, another which examined how tyranny was represented in John Milton's writings, particularly in his revolutionary prose and his early modern epic "Paradise Lost," and an article on heroism in Old English poems.

The competitive nature and high-performance aspect of surfing has undergone substantial growth since the first World Surfing Championships in 1964 (1). As a result, there has been a significant increase in determining the physiological requirements of the sport in order to direct strength and conditioning (S&C) to enhance the performance and fitness qualities of competitive surfers. This article serves to describe the current strength and conditioning practices used in Australian High-Performance Surfing. The movement patterns performed in competitive surfing are discussed specifically in relation to exercise selections and program design. The article showcases program examples and highlights key training areas for surfing performance and injury prevention. It also looks at specific performance benchmarks for both male and female, such as 1RM pull-up (28.75 (±7.95) & 8.44 (±6.17) kg), Mid-thigh pull (3.47 (±0.40) & 2.84 (±0.44) N•BW-1) and drop-and-stick landing (2.7 (±0.4) & 3.9 (±1.2) N•BW-1 & < 0.68 stabilisation), respectively due to their positive transfer to the biomechanics of surfing performance and how this data influences program design. The surfing season is divided into four training phases: (1) the transition phase (TP), (2) general preparation phase (GPP), (3) specific preparation phase (SPP) and (4) competition phase (CP). Athletes complete three weekly S&C sessions in the both the GPP and SPP phase to firstly build foundation strength and work capacity before further developing strength and power. Finally, throughout the CP, three weekly sessions are prescribed with emphasis of training shifting towards maintenance of strength and power. Recommendations provided in this article may assist S&C coaches in developing and selecting exercises for programs that enhance surfing performance. [ABSTRACT FROM AUTHOR]

The pre-season plays a crucial role in the preparation of professional football players, as it allows for an extensive focus on training sessions compared to the more congested schedules during the in-season period, especially in professional football leagues. This study aimed to describe the workload during a 6-week pre-season in Belgian professional football players and to analyse and compare the workloads for players in each microcycle according to several variables of external workload (e.g., distance covered at some velocities). Seventeen male Belgian professional football players competing in the second division of the Belgian league system participated in the study. Throughout the 6 weeks, the players were closely monitored during both training sessions and friendly matches using Global Positioning System (GPS) devices. Several parameters, including total distance covered and distance at different velocities, were recorded. Accelerating and decelerating distances, as well as the number of sprints, were also captured. Statistical analysis was based on a repeated measures ANOVA, percentage dynamics, and effect size calculations. The results obtained showed a progressive increase in the distance travelled at different intensities from week 1 (i.e., lower values) to week 3 (i.e., higher values), with reductions in these values in week 6, prior to the start of the official competition. Similarly, the peak of accelerations and decelerations were observed in week 2 and week 3, with decrements at the end of the pre-season period. This comprehensive investigation attempts to shed light on the effects and dynamic changes in external workload during the crucial pre-season, contributing valuable insights for coaches and practitioners in football conditioning and training programs, especially concerning optimal preparation for the beginning of the league’s season.

This introductory essay overviews the state of scholarship and controversies in the field of Islamic art, in tandem with the gradual reappraisal of Persian art, from around 2000 to the present. By surveying twenty-year debates concerning the academic and display genre called ‘Islamic art’, as well as the reformulating process of the art historical concept ‘Persian art’, this essay seeks an alternative pathway to put several contentious debates concerning art history in general and Persian art in particular into fruitful discussion.

This paper outlines a framework for strength training as a dynamical model of perceptual-motor learning. We show, with emphasis on fixed-point attractor dynamics, that strength training can be mapped to the general dynamical principles of motor learning that arise from the constraints on action, including the distribution of practice/training. The time scales of the respective dynamics of performance change (increment and decrement) in discrete strength training and motor learning tasks reveal superposition of exponential functions in fixed-point dynamics, but distinctive attractor and parameter dynamics in oscillatory limit cycle and more continuous tasks, together with unique timescales to process influences (including practice, learning, strength, fitness, fatigue, warm-up decrement). Increments and decrements of strength can be viewed within a dynamical model of change in motor performance that reflects the integration of practice and training processes at multiple levels of learning and skill development.

The impact of the six-again rule change on the movement of National Rugby League (NRL) athletes was examined. Player Global Navigation Satellite System (GNSS) data (10 Hz) was collected from 42 athletes who competed in 56 matches across the 2019 to 2021 NRL seasons. Maximal mean speed (m·min−1) and acceleration (m·s−2) were established across a 10 s to 10-min duration via raw GNSS files, with subsequent intercept (mean estimates) and slope values determined via power law analysis. The distributions of match distance (m) and impulse (kN·s−1) were established during ball-in-play time. To determine the significance between positions and seasons under different rules, linear mixed models were used. Effects were described using standardised effect sizes (ES) with 90% confidence limits (CL). Acceleration intercepts (power law-derived) across all positions were substantially greater (>0.6 SD) following the introduction of the six-again rule in the 2020 (mean ± SD; 1.02 ± 0.10 m·s−2) and 2021 seasons (1.05 ± 0.08 m·s−2) compared to the 2019 season (0.91 ± 0.07 m·s−2). Mean acceleration during ball-in-play time was greater in 2020 (ES; 90% CL = 0.75; ± 0.32) compared to 2019. The acceleration requirements of rugby league increased across all positional groups following the modification in NRL competition rules. Practitioners should tailor training programs for athletes to reflect the increased acceleration intensity found under the revised competition format. [ABSTRACT FROM AUTHOR]

Purpose: We evaluated the extent of changes in training practices, recovery, mental health, and sleep patterns of athletes during the early COVID-19 lockdown in a single country-cohort. Methods: A total of 686 athletes (59% male, 41% female; 9% World Class, 28% International, 29% National, 26% State, 8% Recreational) from 50 sports (45% individual, 55% team) in Malaysia completed an online, survey-based questionnaire study. The questions were related to training practices (including recovery and injury), mental health, and sleep patterns. Results: Relative to pre-lockdown, training intensity (-34%), frequency (-20%, except World-Class), and duration (-24%-59%, especially International/World-Class) were compromised, by the mandated lockdown. During the lockdown, more space/access (69%) and equipment (69%) were available for cardiorespiratory training, than technical and strength; and these resources favoured World-Class athletes. Most athletes trained for general strength/health (88%) and muscular endurance (71%); and some used innovative/digital training tools (World-Class 48% vs. lower classification-levels =34%). More World-Class, International, and National athletes performed strength training, plyometrics, and sport-specific technical skills with proper equipment, than State/Recreational athletes. More females (42%) sourced training materials from social media than males (29%). Some athletes (38%) performed injury prevention exercises; 18% had mild injuries (knees 29%, ankles 26%), and 18% received a medical diagnosis (International 31%). Lower-level athletes (e.g., State 44%) disclosed that they were mentally more vulnerable; and felt more anxious (36% vs. higher-levels 14%-21%). Sleep quality and quantity were "normal" (49% for both), "improved" (35% and 27%), and only 16% and 14% (respectively) stated "worsened" sleep. Conclusion: Lockdown compromised training-related practices, especially in lowerlevel athletes. Athletes are in need of assistance with training, and tools to cope with anxiety that should be tailored to individual country requirements during lockdown situations. In particular, goal-driven (even if it is at home) fitness training, psychological, financial, and lifestyle support can be provided to reduce the difficulties associated with lockdowns. Policies and guidelines that facilitate athletes (of all levels) to train regularly during the lockdown should be developed. [ABSTRACT FROM AUTHOR]

This article analyses the development of the Council of Social Service for Wales during what is often called the Golden Age of the Welfare State. Recovering the neglected history of the peak organisation for voluntary social service in Wales adds to our understanding of the histories of social policy and postwar Wales. The article addresses social policy from a doubly peripheral perspective – it attends to a territorial periphery of the UK State while voluntary action can be left at the margins of Welfare State analysis. From this perspective we hope to cast new light on the historiography of the 'British Welfare State' [ABSTRACT FROM AUTHOR]

It is widely accepted that adolescents can enhance sporting performance with targeted training interventions. At present, there is no literature around the implementation of a targeted training program inside the physical education (PE) curriculum to enhance the physical performance of students in PE. The purpose of this case study is to present a periodised training program that took students through multiple blocks of training. The intention was to have them 'peak' at the end of the unit, allowing them to achieve the highest possible marks for the physical activity of long jump. Students (8 male participants, age 17.43 ± 0.24 years, height 181 ± 5.0 cm, weight 70.3 ± 6.1 kg, no prior experience in the sport of long jump) undertook 38 lessons for training. The training program was divided into pre-season, as well as an inseason phase that included pre-competition and in-competition sub-phases. The participants performed four selected tests: 1 repetition maximum (RM) back squat, countermovement jump (CMJ), 30 m sprint and the event test of performing a long jump. By targeting the key underlying physiological requirements for the sport of long jump, all participants in this study where able to improve their strength (15.60%), power (7.10%) and speed (3.59%), but most importantly, all made improvements in their long jump (5.43%). The authors posit that by increasing the participants physiological capability, each student was able to demonstrate the relevant movement strategies and sequences to a higher standard, resulting in higher marks being awarded for physical performance. The authors suggest that there is an opportunity for strength and conditioning (S&C) coaches currently working in schools to add value by offering knowledge and skills that the PE teacher may lack.

In each country, in the economy observed over long periods of time, usually we can find some developmental phases due to socioeconomic changes, globalization, political decisions, and unexpected events. The identification of such phases, their duration, turning points in the trends of macroeconomic indicators, and some other early signals comprise interesting goals for research. The aim of this paper is to find homogeneous phases in the economic development of Poland from 2007-2019. Eight monthly variables were used, including data on labour markets, salaries, inflation, manufacturing, retail sales, exports, and the overall business climate. This multidimentional time-series dataset was partitioned using cluster analysis methods, namely Ward's agglomerative method and k-means. Seven sub-periods have been found and they are illustrated by segmented trends and displayed as models and graphs. Economic interpretation of the developments in the phases is explained and interpreted below. Looking at the periods that have been found, one can consider the quality of economic and political decisions, both within the world in general and the European economic situation. This paper presents original periodisation of Poland's economy and is based on real monthly data with the use of a clustering approach to multidimensional time series. [ABSTRACT FROM AUTHOR]

There is no consensus among BIM practitioners and theorists as to whether BIM is an evolution from CAD systems or a total revolution in construction. In the history of BIM, there have been a number of important, epoch-making events that have changed the direction of BIM. From the concept of BIM, to the technology used in construction, to the methodology, to the process, to the holistic idea of BIM, one can see the evolution of user approaches to its use. BIM has two dimensions: an information system and a philosophy. Thus, BIM is both a tool and a philosophy that brings about a revolution. Several decades of BIM development prompts reflection and the delineation of perhaps some stages of maturation. This paper presents a theory of cognition (epistemology), essential for understanding the history of BIM. The genesis of the separation of BIM from CAD makes it clear that specific factors influenced further developments. Thus, the aim of the study was to periodise BIM in view of various factors that may be relevant to researchers interested in BIM and companies using or implementing BIM. The literature survey maintained inclusivity to reflect both positive and critical aspects of BIM. The periodisation of the history of BIM was done due to 3 factors: idea, approach and organisational culture. The development of the BIM idea established the direction in which systems and software development was heading, the user approach forced interoperability and the organisational culture emphasised increasing efficiency. Working according to the openBIM approach or within an IPD framework is probably not the end of the anticipated level of BIM maturity. The division into periods will probably be the subject of much discussion, but will perhaps set the directions for the future. [ABSTRACT FROM AUTHOR]

Short-term periods of increased resistance exercise training are often used by athletes to enhance performance, and can induce functional overreaching (FOR), resulting in improved physical capabilities. Non-functional overreaching (NFOR) or overtraining syndrome (OTS), occur when training demand is applied for prolonged periods without sufficient recovery. Overtraining (OT) describes the imbalance between training demand and recovery, resulting in diminished performance. While research into the effects of resistance exercise OT has gathered attention from sports scientists in recent years, the current research landscape is heterogeneous, disparate, and underrepresented in the literature. To date, no studies have determined a reliable physiological or psychological marker to assist in the early detection of NFOR or OTS following periods of resistance exercise OT. The purpose of this work is to highlight the conceptual and methodological limitations within some of the current literature, and to propose directions for future research to enhance current understanding.

This study reports on the content and periodisation of the preseason field-based training for a professional rugby league team. Thirty professional male rugby league players (26 ± 5 years, 180.9 ± 6.5 cm, 94 ± 9 kg) completed an 8-week preseason. Global positioning system devices and heart rate were used to monitor physical and physiological responses of different field-based training components (speed, conditioning, rugby skill and game-based training). Rugby skill training contributed the most to the total distance covered, conditioning was the greatest contributor to high-speed running (>15 km/h) and game-based training provided the greatest high metabolic distance (>20 W/kg) and overall external load. Game-based training provided the greatest time with heart rate ≥80% estimated maximum. The weekly preseason cycle had lower loads on Monday and Thursday whereas Tuesday and Friday produced the highest loads. The preseason described herein adopted a progressive overload comprising a weekly undulating cycle. This study emphasises how skill and games-based training contributes significantly to the overall load of a professional rugby league team's preseason with more traditional conditioning promoting high-speed running load and high metabolic load.

Coaches of youth judo athletes might be under the influence of some extraordinary elite judo athletes that have won elite competitions at a relatively young age and might put youth athletes under pressure to gain as much fighting experience as fast as possible. The present study aims to present a 5-year competition structure, volume and age competition categories (ACC) range in which youth judokas competed with 10-year dropout status. Data from 46 judokas were collected (M = 24; F = 22) for four categorisation classes (National-NC; Perspective-PC; International-IC; World class-WC). Competitive structure, volume, performance and number of ACC were collected from 2009 to 2013 for all age groups from scores and standings records of the National Federation. Youth judokas competed in 8 (±2) competitions per year and also competed in 3 (±1) ACC. Abroad competitions affect the fighting experience and competitive success (CS). CS showed positive correlations with the number of ACC in the year 2009 (p = 0.01), 2010 (p = 0.01) and 2011 (p = 0.04). The final observed years' CS 2012 (p = 0.009) and 2013 (p = 0.002) showed a negative association with the number of ACC. CS in the final observed year 2013 showed a positive association (p = 0.012) with the dropout status in 2018 and a negative one with the number of abroad competitions in 2013 (p = 0.029). In total, 52% dropout was noted in 10 years. This ''playing-up" approach was shown to be successful in creating youth medalists. However, just in the short term, if implemented for too long, it starts to affect competition success negatively and increases youth athletes' dropout. Therefore, coaches should include more competitions abroad in competitors' primary age group, while training sessions could be done with higher age groups which would allow for gathering additional experience in a more controlled environment in their yearly periodisation.

Without forming a well‑defined regional group, the relatively synchronous “Celtic” extracarpathian discoveries (LT C1) form a distinct horizon. For the name of this horizon, one could appeal to the funerary discoveries from Glăvănești (in Moldova) and Telești (in Oltenia). The Glăvănești‑Telești horizon is subsequent to the “Getic” horizon of the Thracian fibulae (Zimnicea‑Peretu group) which, in turn, can be synchronized for the time being only to the early La Tène (LT B1– B2). In addition to the chronological justification, the succession of these “horizons” also has a cultural one. The magnificent inventories such as those from Agighiol, Peretu et al. reflects stable “northern Thracian” power structures that could not coexist at the Lower Danube with power structures of intra‑Carpathian (“Celtic”) origin, e. g. the tomb from Telești. In other words, funerary contexts, such as those at Telești or Mezek, could not be established in the Lower Danube region until, more likely, after the decline of North Thracian power structures. In turn, the Central European cultural patterns mediated by the “Celtic” power structures lost their vigour, expressiveness and consistency at the Lower Danube with the formation of the Poienești‑Lucașeuca group. The Gebhard 14 type fibula with spheres from Poienești‑Măgură and the two Werner XIV type horse‑bits discovered in the same site can be perceived as exponents of the extra‑Carpathian “Celtic” horizon. By analogy with the fibulae from Wederath (tomb 96) and Kălnovo (tomb 3), the one from Poienești could be dated in the first half of the middle La Tène (maybe even during the LT– C1b sub‑phase !). The earliest necropolis of the Poienești‑Lucașeuca group (respectively, the one from Poienești) could not be organized until after the dissolution of the extra‑Carpathian “Celtic” horizon. The present contribution is not intended to resolve issues related to the precise periodization and absolute dating of the transition between the two successive extra‑Carpathian horizons, “Celtic” (Glăvănești‑Telești) and “Bastarnian” (Poienești‑Lucașeuca). However, the beginnings of the latter horizon cannot be adequately determined without the plenary debate on the end of the former

Purpose: We evaluated the extent of changes in training practices, recovery, mental health, and sleep patterns of athletes during the early COVID-19 lockdown in a single country-cohort.Methods: A total of 686 athletes (59% male, 41% female; 9% World Class, 28% International, 29% National, 26% State, 8% Recreational) from 50 sports (45% individual, 55% team) in Malaysia completed an online, survey-based questionnaire study.

Deloading refers to a purposeful reduction in training demand with the intention of enhancing preparedness for successive training cycles. Whilst deloading is a common training practice in strength and physique sports, little is known about how the necessary reduction in training demand should be accomplished. Therefore, the purpose of this research was to determine current deloading practices in competitive strength and physique sports. Eighteen strength and physique coaches from a range of sports (weightlifting, powerlifting, and bodybuilding) participated in semi-structured interviews to discuss their experiences of deloading. The mean duration of coaching experience at ≥ national standard was 10.9 (SD = 3.9) years. Qualitative content analysis identified Three categories: definitions, rationale, and application. Participants conceptualised deloading as a periodic, intentional cycle of reduced training demand designed to facilitate fatigue management, improve recovery, and assist in overall training progression and readiness. There was no single method of deloading; instead, a reduction in training volume (achieved through a reduction in repetitions per set and number of sets per training session) and intensity of effort (increased proximity to failure and/or reduction in relative load) were the most adapted training variables, along with alterations in exercise selection and configuration. Deloading was typically prescribed for a duration of 5 to 7 days and programmed every 4 to 6 weeks, although periodicity was highly variable. Additional findings highlight the underrepresentation of deloading in the published literature, including a lack of a clear operational definition.

Once, when questioned about the originality of Umberto Eco’s Il nome della rosa (1980), Richard Krautheimer gave one of his rare and atypically acerbic replies: “you obviously haven’t read much Sherlock Holmes”. In many ways the volume discussed here provoked in the reviewer a similar response because, when reading through a number of the ten papers presented in these conference proceedings, he kept thinking: “but what about Argan?”. In this case Giulio Carlo Argan playing Canon Doyle, to Gilles Deleuze’s Eco, the latter’s Le Pli of 1988 to Argan’s brilliant but overlooked essay “La retorica e l’arte barocca” of 1955 which is not cited a single time in this book nor present in the bibliography. Acknowledging the importance of Argan (mentioned only in passing on p. 22) would not make Deleuze’s work appear any less innovative, but it certainly would have helped explain more persuasively the significant shifts in post-war perception and reception of the Baroque that were part of the historical preamble to the appearance of Leibniz et le baroque.

Successful performances in rugby league require the ability to engage in repeated contact efforts with minimal recovery while maintaining a high running intensity. The capacity to express high levels of time-limited force appears to underlie many important physical attributes required to meet the repeated-effort demands of rugby league play. If appropriately periodised and integrated into the training plan, resistance exercise that sufficiently loads the eccentric phase of movement may provide a beneficial stimulus to improve players’ force-generating capacity. Comprehensive reviews relating to the adaptive effects of eccentric training and the methods most commonly prescribed in practical environments are available and may provide context for applying these strategies. However, no literature to date has specifically discussed the planning and programming of eccentric resistance exercise to enhance force production characteristics in elite athletes. Therefore, this narrative review focuses on the periodisation of eccentrically-integrated resistance training during a 17-week National Rugby League pre-season phase. To help guide programming during the pre-season period, the 17-week timeline is divided into several phases (i.e., general preparation, special preparation, active rest, and pre-competition). Within the periodised model, eccentric exercise parameters (i.e., volume, load [% 1RM]) are manipulated to progressively increase the rate of muscle lengthening velocity over the pre-season phase and sequentially elicit changes in muscle-tendon properties and neural function that culminate in improving muscular strength expression.

To determine the changes in physical qualities of academy rugby union players over a 10-week unsupervised off-season period. Body mass, jump height, sprint performance, and intermittent running (30:15 IFT) of 64 academy rugby union players (age = 17.2 ± 0.4 y) were recorded before and after the off-season. Changes in body mass (+1.4 ± 1.3 kg), countermovement jump (−2.2 ± 1.2 cm), squat jump (-1.5 ± 1.8 cm), 10 m sprint (+0.06 ± 0.05 s), 40 m sprint (+0.13 ± 0.11 s) and 30:15 IFT (-0.8 ± 0.8 kmŸh−1) were observed (P < 0.001, d = -1.77 to 0.47). Only changes in body mass were greater in forwards than backs (P = 0.036, d = 0.46). Players with higher end-of-season body mass, squat jump and 30:15 IFT had greater off-season changes (P = < 0.001 to 0.044; d = 0.63 to 0.94), whilst the pre-post difference in body mass influenced CMJ (P = 0.005, d = 0.75) and 10 m momentum change (P < 0.001, d = 1.61). Understanding the individuality of the changes in physical qualities of academy rugby union players during the off-season is important to ensure players return safely to pre-season training loads.

The main objective of this paper is to propose the first tentative periodisation of the Old Tibetan (OT) language based on a group of related sound changes. As it occurs, at the time of the script invention in the 630s, Early Old Tibetan (EOT) must have had four onset clusters /s/+liquid: zr-, sr-, zl-, and sl-. However, in Old Tibetan as well as in Classical Tibetan (CT) we only find sr-, zl-, and sl-, whereas neither of them is attested in modern spoken varieties of Tibetan. In order to find out what has happened to the EOT zr-, I have traced reflexes of CT sr-, zl-, and sl- in modern dialects. Since changes that have occurred with respect to zl- and sl- parallel each other, I postulate that the same analogy can be applied to sr- to determine in what direction the EOT onset zr- might have evolved. Having reconstructed the development of the onsets in the most conservative dialects of Western Archaic Tibetan (WAT) and Amdo Tibetan (AT), I juxtapose these findings with historical facts that can help us to explain modern distribution of Tibetan dialects. Historical events recorded in OT documents combined with our knowledge of other early sound changes in Old Tibetan constitute a time frame for dating the reconstructed changes and thereby allow us to establish the first tentative linguistic periodisation of Old Tibetan.

This article aims to detail the construction and results of a new periodization of ceramic productions from megalithic sites in Senegal and The Gambia (8th-16th centuries CE). For the first time there, this model is based on carefully documented stratigraphic contexts obtained on the necropolis of Wanar (Senegal). The intersection of typological and technological approaches reveals different productions, reflections of ceramic traditions, and distinct craft groups. In Wanar, the succession of these productions with specific morpho-functional characters could be correlated with the emergence of particular architectural styles. This periodization also integrates materials from previous excavations and thus offers a renewed reading of it. The distinction between ceramic vestiges anterior to the erection of monumental architectures and others fully participating in their ritual functioning leads to question both the status of ceramic productions and sites. This research finally contributes to integrating Senegambian pottery production into the broader context of medieval West Africa. [ABSTRACT FROM AUTHOR]

Mental fatigue has been shown to negatively influence physical, technical and tactical aspects of sporting performance. However, mental fatigue is not routinely monitored or managed in elite sport and it is not clear whether mental fatigue occurs and/or changes across the varied contextual demands experienced by elite athletes in training, preparation and competition. This study explored self-report measures of mental fatigue across eight training camps and six competition periods (two benchmark tournaments and four international test series) with international netballers (n = 22, 25.9 ± 2.7 years) during the 2018–2019 representative period. Mental fatigue was higher during training camps (p < 0.001; 3.20 [3.12, 3.27]) and preparation camps (p < 0.05; 3.27 [3.19, 3.34]) compared to the competition periods (3.49 [3.44, 3.55]). Significant within-group differences were also identified between individual preparation camps and competition subsets. Higher mental fatigue was reported during the preparation camp for international test series 2 comparative to the preparation camp for benchmark tournament 1 (p = 0.047). For individual competitions; greater mental fatigue was found during the international test series 3 competition in comparison to both the benchmark tournament 1 (p <0.001) and international test series 1 (p = 0.020) competition periods. International representative netballers experience differing levels of mental fatigue across training and preparation camps and competition periods. Practitioners should be aware that athletes report instances of elevated mental fatigue across camps, and competition. Mental fatigue is not limited to competition and thus is recommended to be monitored during periods of training and preparation for competition. International representative netballers experience differing levels of mental fatigue across camp and competition environments. Mental fatigue was higher during training camps and preparation camps compared to the competition periods. Mental fatigue is not limited to competition so is recommended to be monitored during periods of training and preparation for competition. [ABSTRACT FROM AUTHOR]
