- Abstract
158 p., Esta tesis aborda varias preguntas abiertas sobre los efectos de los diferentes modelos de prescripción de entrenamiento en intervalos de alta intensidad (HIIT) con la respuesta fisiológica y el rendimiento en corredores de fondo entrenados. La prescripción de entrenamiento de HIIT generalmente se realiza usando un enfoque empírico común y estandarizado, en el que los corredores de un nivel similar entrenan juntos usando el mismo esquema HIIT. Sin embargo, estudios previos mostraron que es posible enfocarse en algunas adaptaciones fisiológicas individualizando las prescripciones de HIIT acorde con las características fisiológicas de los corredores y sus respuestas al ejercicio. Esto puede estar relacionado al mayor tiempo pasado en (o cerca del) V̇ O2max y, por lo tanto, al estímulo cardiorrespiratorio más fuerte que se produce con este modelo de prescripción de entrenamiento. Dado que, en el enfoque estandarizado, en el que la velocidad es la misma para todos, los corredores que caen fuera del rango de intensidad deseado pueden producirse menores ganancias (o nulas) en la aptitud cardiorrespiratoria, se puede observar un efecto promedio de grupo más pequeño junto con una mayor heterogeneidad del efecto de entrenamiento.

- Abstract
The International Olympic Committee (IOC) recently published a framework on fairness, inclusion, and nondiscrimination on the basis of gender identity and sex variations. Although we appreciate the IOC's recognition of the role of sports science and medicine in policy development, we disagree with the assertion that the IOC framework is consistent with existing scientific and medical evidence and question its recommendations for implementation. Testosterone exposure during male development results in physical differences between male and female bodies; this process underpins male athletic advantage in muscle mass, strength and power, and endurance and aerobic capacity. The IOC's “no presumption of advantage” principle disregards this reality. Studies show that transgender women (male-born individuals who identify as women) with suppressed testosterone retain muscle mass, strength, and other physical advantages compared to females; male performance advantage cannot be eliminated with testosterone suppression. The IOC's concept of “meaningful competition” is flawed because fairness of category does not hinge on closely matched performances. The female category ensures fair competition for female athletes by excluding male advantages. Case-by-case testing for transgender women may lead to stigmatization and cannot be robustly managed in practice. We argue that eligibility criteria for female competition must consider male development rather than relying on current testosterone levels. Female athletes should be recognized as the key stakeholders in the consultation and decision-making processes. We urge the IOC to reevaluate the recommendations of their Framework to include a comprehensive understanding of the biological advantages of male development to ensure fairness and safety in female sports.

- Abstract
There is a growing interest in studies involving carbohydrate (CHO) manipulation and subsequent adaptations to endurance training. This study aimed to analyze whether a periodized carbohydrate feeding strategy based on a daily training session has any advantages compared to a high-carbohydrate diet in well-trained cyclists. Seventeen trained cyclists (VO2peak = 70.8 ± 6.5 mL·kg−1·min−1) were divided into two groups, a periodized (PCHO) group and a high-carbohydrate (HCHO) group. Both groups performed the same training sessions for five weeks. In the PCHO group, 13 training sessions were performed with low carbohydrate availability. In the HCHO group, all sessions were completed following previous carbohydrate intake to ensure high pre-exercise glycogen levels. In both groups, there was an increase in the maximal lactate steady state (MLSS) (PCHO: 244.1 ± 29.9 W to 253.2 ± 28.4 W; p = 0.008; HCHO: 235.8 ± 21.4 W to 246.9 ± 16.7 W; p = 0.012) but not in the time to exhaustion at MLSS intensity. Both groups increased the percentage of muscle mass (PCHO: p = 0.021; HCHO: p = 0.042) and decreased the percent body fat (PCHO: p = 0.021; HCHO: p = 0.012). We found no differences in carbohydrate or lipid oxidation, heart rate, and post-exercise lactate concentration. Periodizing the CHO intake in well-trained cyclists during a 5-week intervention did not elicit superior results to an energy intake-matched high-carbohydrate diet in any of the measured outcomes.

BACKGROUND: In the last decades, emerging evidence has shown that muscle growth is not homogeneous along a muscle head. This phenomenon is known as regional muscle hypertrophy and has led to several questions regarding the implications it may have for health and sports performance. OBJECTIVE: The aim of this study was to determine whether regional hypertrophy can be predicted by surface electromyography (sEMG). METHODS: 36 participants performed two arm exercises (preacher curls and inclined curls) in a random order to muscle failure at 70% of the 1 RM of the bicep curl exercise. As every participant performed a different number of repetitions, Peak sEMG and the integral of the sEMG of the last 3 repetitions was analyzed an compared to previously performed maximal voluntary isometric contractions (MVIC). RESULTS: The independent sample t -tests showed no significant differences neither in the peak nor in the integral of the sEMG between exercises for any given region. CONCLUSIONS: sEMG cannot be used to predict regional hypertrophy. [ABSTRACT FROM AUTHOR]

Purpose: Optimal training for endurance performance remains a debated topic. In this case study, the training of a world-class middle-/long-distance runner over a year's duration is presented. Methods: The training is analyzed via 2 methods to define training intensity distribution (TID) (1) by physiological zones and (2) by zones based on race pace. TID was analyzed over the full season, but also over the final 6, 12, and 26 weeks to allow for consideration of periodization/phases of season. The results of both methods are compared. Other training data measured include volume and number of sessions. Results: The average weekly volume for the athlete was 145.8 (24.8) km·wk
−1 . TID by physiological analysis was polarized for the last 6 weeks of the season but was pyramidal when analyzed over the final 12, 26, and 52 weeks of the season. TID by race-pace analysis was pyramidal across all time points. The athlete finished 12th in the final of the World Championship 5000-m and made the semifinal of the 1500-m. He was ranked in the top 16 in the world for 1500, 5000, and 10,000 m. Conclusion: The results of this study demonstrate a potential flaw with recent work suggesting polarized training as the most effective means to improve endurance performance. Here, different analysis methods produced 2 different types of TID. A polarized distribution was only seen when analyzed by physiological approach, and only during the last 6 weeks of a 52-week season. Longer-term prospective studies relating performance and physiological changes are suggested. [ABSTRACT FROM AUTHOR]- Published

- Abstract
212 p., Dado que la función principal de los entrenadores es mejorar el rendimiento de sus atletas, se han estudiado varias estrategias, como la mejora del rendimiento post-activación (PAPE), una estrategia para mejorar la producción de fuerza voluntaria de manera aguda. Otro factor importante que tienen en cuenta los entrenadores es la región de estancamiento, la región donde se puede fallar el levantamiento.La presente tesis, compuesta por una revisión sistemática y dos estudios originales tiene como propósito: (i) observar si una estrategia para mejorar el rendimiento de forma aguda (PAPE) es efectiva sobre la cinemática y las características de la región de estancamiento, (ii) comparar diferentes protocolos de PAPE basados en diferentes regímenes de contracción y (iii) estudiar si un protocolo de PAPE puede mejorar el volumen de entrenamiento de fuerza.La principal conclusión de esta tesis es que los protocolos alternativos (isométricos) son de mayor utilidad que los tradicionales durante la competición, mientras que los protocolos tradicionales son útiles en tareas con cargas submáximas y de larga duración.

- Abstract
The aim of the present study was to analyse the role of exercises' resistance profile in regional hypertrophy. Thirty-eight healthy women completed a 9-week resistance training program consisting of either 4 sets of 12 repetitions to volitional failure of inclined bicep curls (INC group) or preacher curls (PREA group), three times per week. Pre- and post-intervention muscle thickness was measured using B-mode ultrasound imaging with a linear-array transducer. Scan acquisition sites were determined by measuring 50%, 60% and 70% of the distance between the posterior crest of the acromion and the olecranon. Statistical significance was set at p < 0.05. No region of the INC group grew when comparing pre- to post-intervention. The 70% region of the PREA group grew significantly (muscle thickness increased from 2.7 ± 0.43 cm to 2.94 ± 0.44 cm). We found no growth differences between regions when analysing per group (p = 0.274), region (p = 0.571) or group*region (p = 0.367). Our results show that the distal region of the arm grows in response to the preacher curl that places the highest amount of strain in the range of motion in which the arm muscles are more elongated.

- Abstract
Post-Activation Performance Enhancement (PAPE) has been commonly used as a strategy to improve acute force production, although its effects on performance to volitional failure are still unknown. The aim of this study was to analyse the influence of a PAPE protocol on bench press performance in a training set to volitional failure in trained individuals. Fourteen participants with at least two years of resistance training experience (age 24.57 ± 2.7 years; body mass 77.47 ± 12.2 kg; body height 174.21 ± 7.4 cm; medium grip bench press 1 repetition maximum (1RM): 101.6 ± 25.8 kg), of which 14 completed the control protocol and 12 completed the experimental protocol, took part in the study. After a standardised warm-up, participants completed three sessions: 1) a 1RM test for the medium grip bench press, 2) a control condition consisting of a set of the bench press to volitional failure with 80% 1RM (CON), and 3) an experimental condition consisting of a set of the bench press to volitional failure with 80% 1RM after a PAPE protocol (PAPE). The PAPE protocol consisted of a heavy set of one repetition with their 93% 1RM as the conditioning activity. Under the PAPE condition, participants performed significantly more repetitions than under the CON condition (p = 0.008, ES = 0.5, small effect), their last repetition was slower (p = 0.02, ES = 0.52, small effect) and presented a higher velocity loss (p = 0.004, ES = 0.75, moderate effect). These results suggest that a traditional PAPE protocol improves the number of repetitions performed to volitional failure.

34 p. -- Bibliogr.: p. 32-34, El monohidrato de creatina es un suplemento que cada día más y más deportistas profesionales y aficionados usan con el objetivo de mejorar sus marcas o su rendimiento físico en las diferentes modalidades que practican. Este estudio es una revisión sistemática de la literatura que tiene como objetivo evaluar la eficacia de la suplementación con creatina en futbolistas. Se realizaron búsquedas en varias bases de datos (Pubmed, Scopus y Web of Science) durante el mes de abril del año 2023 con el fin de encontrar ensayos clínicos controlados y aleatorizados que examinaran los efectos de la creatina en el rendimiento deportivo de los futbolistas. Esta búsqueda concluyó con un total de 6 estudios de intervención a los que después se añadieron manualmente otros 4 estudios. Los resultados de estos estudios sugieren que mediante una suplementación con creatina de 20 y 30 gramos diarios divididas en 3 o 4 ingestas puede mejorar el rendimiento físico en futbolistas en ciertas situaciones, como en ejercicios de alta intensidad y corta duración. Ejemplo de esto puede ser la prueba de Wingate, (Wingate Anarobic Test), CMJ (Counter Movement Jump) o pruebas de velocidad. Además, se encontró que la creatina puede aumentar la masa muscular y mejorar la recuperación después del ejercicio intenso. Sin embargo, no se ha encontrado evidencia de los beneficios que este suplemento puede aportar en ejercicios de larga duración y menor intensidad. Por otro lado, también se señala que los efectos de la creatina pueden variar según la duración y dosis de la suplementación, así como la edad y el nivel de entrenamiento de los futbolistas. Sería oportuno realizar más investigaciones para comprender mejor los efectos de la creatina en el rendimiento deportivo de los futbolistas y su seguridad a largo plazo. En conclusión, la revisión sistemática sugiere que la suplementación con creatina puede tener efectos positivos en el rendimiento físico de los futbolistas en ciertas situaciones, pero se neces

- Abstract
20 p. -- Bibliogr.: p. 17-20, The main goal of this systematic review was to determine whether there is any interference between concurrent aerobic and resistance training in muscle hypertrophy adaptations in active or resistance trained people. A systematic literature search on 6 databases (PubMed, SPORTDiscus, Scopus, Dialnet, Scielo and Cochrane Library) was conducted in April, 2022 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). After analyzing 362 resultant articles only 5 met the inclusion criteria: a) studies were randomized controlled trials or cohort studies evaluating the effect of concurrent training on muscle mass gains b) studies comparing two groups performed identical resistance training protocols and without the use of external implements (i.e., arterial pressure cuffs); c) interventions lasted at least eight weeks; d) participants were recreationally active people or had previous experience in weight training; e) participants’ age ranged from 18 to 35 years; f) resistance training frequency was at least 3 times/week; g) studies reported direct measurements of muscle thickness, cross-sectional area and/or lean body mass; h) studies were published in peer-review journals. The findings of this review suggest that as long as the training variables are correctly managed there is no interference effect between concurrent aerobic and resistance training in the development of skeletal muscle hypertrophy. Moreover, aerobic training adaptations can be beneficial to the performance of athletes seeking to maximize muscle mass gains.

38 p. -- Bibliogr.: p. 35-38, Indar entrenamendua gaur egun asko gomendatzen den jarduera fisiko mota bat da, dituen onurak ugariak baitira. Indar entrenamenduan asko erabiltzen den GGA-eko ariketa bat press banka dugu. Press banka hain ezaguna den indar ariketa izanik eta powerlifting-a gaur egun bizi izaten ari den hazte prozesuarekin, mugimendu honetan heltze-zabalerak errendimenduan duen eragina aztertzea da ikerketa honen helburua. Horretarako, 3 datu base ezberdinetan bilaketa estrategiko bat egin da, hitz gako eta eragile logiko berdinak erabiliz. Hasiera batean hiru datu baseetako artikuluak batuz 340 artikulu atera dira. Guztiak aztertu ondoren eta izenburu eta abstract bidezko bazterketa egin ostean, inklusio irizpide batzuk ezarri dira. Honako hauek izan dira inklusio irizpideak: a) artikuluak 2015 urtetik aurrera argitaratuak izatea (2015 barne) eta b) press bankako errendimendua aztertzea (ez bakarrik EMG). Bi inklusio irizpide hauek ezarrita 7 artikulu geratu dira, errebisio sistematikoa egiteko erabili direnak hain zuzen ere. Errebisioaren bidez heltze-zabalera ezberdinak konparatu dira hauen arteko ezberdintasunak aztertuz. Konparaketa honetan aldagai ezberdinak hartu dira kontuan, zehazki ikerketa gehienetan aztertzen diren aldagai mekanikoak: SR, barraren abiadura, karga (kg), lana (J), indarra (N), potentzia (W) eta altxaldiaren distantzia zein iraupena. Neurketa horiek heltze-zabalera estuan, ertainean eta zabalean egin dira oro har nahiz eta ikerketa guztietan hirurak ez agertu. Errebisio sistematikoan egindako alderaketan heltze-zabalera ezberdinak konparatzen dira. Ikerketa hauetan lortutako emaitzetan ikusi da aldagai batzuetan errendimendu altuena lortzen dela HZEPB-rekin baina jakinda errebisio honetan Powerlifting kiroleko errendimendua dela oinarria, honetarako garrantzitsuena den aldagaiari (karga) eman zaio garrantzia gehien. Ondorio gisa, esan dezakegu powerlifting-eko errendimendu altuena lortzeko egokiena den heltze-zabalera zabala dela, 81cm-ko marketatik gertu.

A regular endurance training program may elicit different adaptations compared to an isolated training method. In this study, we analyzed the effects of 8 weeks of a regular endurance training program on running economy (RE), particularly neuromuscular and biomechanical parameters, in runners of different athletic abilities. Twenty-four male runners were divided into two groups: well-trained (n= 12) and recreational (n =12). Both groups completed a 4-min running bout at 13 and 17 km·h
-1 , respectively, for the recreational and well-trained group, and a 5-jump plyometric test pre-post intervention. During the training program, participants completed low-intensity continuous sessions, high-intensity interval training sessions, and auxiliary strength training sessions. RE, measured as oxygen cost and energy cost, decreased by 6.15% (p=0.006) and 5.11% (p=0.043), respectively, in the well-trained group. In the recreational group, energy cost of running, respiratory exchange ratio, and leg stiffness decreased by 5.08% (p=0.035), 7.61% (p=0.003), and 10.59% (p=0.017), respectively, while ground contact time increased by 3.34% (p=0.012). The maximum height of the 5-jump plyometric test decreased by 4.55% (p=0.018) in the recreational group. We suggest that 8 weeks of regular endurance training leads to an improvement of ~5% in RE in recreational and well-trained runners with different physiological adaptations between groups and few changes in biomechanical and neuromuscular parameters only in recreational runners.

Post-Activation Performance Enhancement (PAPE) has been commonly used as a strategy to improve acute force production, although its effects on performance to volitional failure are still unknown. The aim of this study was to analyse the influence of a PAPE protocol on bench press performance in a training set to volitional failure in trained individuals. Fourteen participants with at least two years of resistance training experience (age 24.57 ± 2.7 years; body mass 77.47 ± 12.2 kg; body height 174.21 ± 7.4 cm; medium grip bench press 1 repetition maximum (1RM): 101.6 ± 25.8 kg), of which 14 completed the control protocol and 12 completed the experimental protocol, took part in the study. After a standardised warm-up, participants completed three sessions: 1) a 1RM test for the medium grip bench press, 2) a control condition consisting of a set of the bench press to volitional failure with 80% 1RM (CON), and 3) an experimental condition consisting of a set of the bench press to volitional failure with 80% 1RM after a PAPE protocol (PAPE). The PAPE protocol consisted of a heavy set of one repetition with their 93% 1RM as the conditioning activity. Under the PAPE condition, participants performed significantly more repetitions than under the CON condition (p = 0.008, ES = 0.5, small effect), their last repetition was slower (p = 0.02, ES = 0.52, small effect) and presented a higher velocity loss (p = 0.004, ES = 0.75, moderate effect). These results suggest that a traditional PAPE protocol improves the number of repetitions performed to volitional failure. [ABSTRACT FROM AUTHOR]

- Abstract
[EN] The main goal of this study was to compare responses to moderate and high training volumes aimed at inducing muscle hypertrophy. A literature search on 3 databases (Pubmed, Scopus and Chocrane Library) was conducted in January 2021. After analyzing 2083 resultant articles, studies were included if they met the following inclusion criteria: a) studies were randomized controlled trials (with the number of sets explicitly reported), b) interventions lasted at least six weeks, c) participants had a minimum of one year of resistance training experience, d) participants' age ranged from 18 to 35 years, e) studies reported direct measurements of muscle thickness and/or the cross-sectional area, and f) studies were published in peer-review journals. Seven studies met the inclusion criteria and were included in the qualitative analysis, whereas just six were included in the quantitative analysis. All participants were divided into three groups: "low" (<12 weekly sets), "moderate" (12-20 weekly sets) and "high" volume (>20 weekly sets). According to the results of this meta-analysis, there were no differences between moderate and high training volume responses for the quadriceps (p = 0.19) and the biceps brachii (p = 0.59). However, it appears that a high training volume is better to induce muscle mass gains in the triceps brachii (p = 0.01). According to the results of this review, a range of 12-20 weekly sets per muscle group may be an optimum standard recommendation for increasing muscle hypertrophy in young, trained men.

- Abstract
42 p. : il. -- Bibliogr.: p. 38-42, [ES] El objetivo de esta revisión fue conocer que factores fisiológicos influyen de manera más significativa en el rendimiento de corredores de élite a lo largo de una prueba de maratón. Para ello se realizó una revisión sistemática de los distintos estudios científicos que analizasen los principales factores fisiológicos que influyen en el rendimiento deportivo de los corredores de maratón de élite. Tras realizar la búsqueda en la base de datos PubMed, 6 artículos cumplieron con los criterios de inclusión. Se encontró que el consumo máximo de oxígeno (VO2 max) es un factor determinante del rendimiento de maratón entre corredores de un nivel heterogéneo. Sin embargo, entre corredores de élite de un nivel similar, este factor pasa a un segundo plano y cobran mayor importancia la capacidad que tiene cada atleta para correr a ritmos elevados manteniendo un estado metabólico lo más estable posible, es decir, utilizando la menor cantidad de energía y de oxígeno posible. Por este motivo, se ha encontrado evidencia científica de que la economía de carrera (RE) puede ser el factor más determinante en el rendimiento en las pruebas de maratón de la actualidad., [EN] The aim of this review was to identify which physiological factors influence most significantly the performance of elite runners throughout a marathon event. For this purpose, a systematic review of the different scientific studies that analyzed the main physiological factors that influence the athletic performance of elite marathon runners was carried out. After searching the PubMed database, 6 articles met the inclusion criteria. Maximal oxygen uptake (VO2 max) was found to be a determinant of marathon performance among runners of a heterogeneous level. However, among elite runners of a similar level, this factor takes a back seat to the ability of each athlete to run at high paces while maintaining a metabolic state as stable as possible, i. e. using as little energy and oxygen as possible. For this reason, scientific evidence has been found that running economy (RE) may be the most important determinant of performance in today's marathon events.

23 p. -- Bibliogr.: p. 21-23, El objetivo de este estudio era analizar la relación entre las variables antropométricas y el salto vertical en participantes con experiencia en el entrenamiento de fuerza y a su vez comparar estas variables tras una intervención de ese mismo tipo de entrenamiento. Los 27 participantes (edad = 25.4 ± 4.8 años; peso corporal = 76.2 ± 7.7 kg; altura = 176 ± 6.5 cm; porcentaje de grasa = 10.6 ± 2.1) realizaron un test de salto vertical con contra-movimiento (CMJ) del que se obtuvo la altura máxima utilizando las células fotoeléctricas de Optojump. Las variables antropométricas se midieron siguiendo el protocolo ISAK. Estas mediciones se tomaron tanto antes como después de la intervención del entrenamiento de fuerza. La intervención consistió en realizar dos entrenamientos de pesas del miembro inferior a la semana en los que debían de realizar 4 series de 12 repeticiones al fallo de un ejercicio en concreto y tuvo una duración de 6 semanas. Los resultados del estudio muestran que se encontraron correlaciones significativas inversas entre el CMJ y los sumatorios de pliegues tanto en el pretest (r = -.439; p < 0.05) como en el postest (r = -.502; p < 0.01). A su vez, después de la intervención se encontraron correlaciones significativas positivas entre el salto vertical y el porcentaje de masa muscular (r = .447; p < 0.05). Por otro lado, tanto el CMJ, el porcentaje de masa muscular y el sumatorio de pliegues mejoraron tras la intervención, siendo únicamente significativo el sumatorio de pliegues (p = 0.015). En conclusión, en participantes con experiencia en el entrenamiento de fuerza existe una correlación inversa entre el salto vertical y el sumatorio de pliegues y también una correlación positiva entre el salto vertical y el porcentaje de masa muscular.

- Abstract
158 p., Esta tesis aborda varias preguntas abiertas sobre los efectos de los diferentes modelos de prescripción de entrenamiento en intervalos de alta intensidad (HIIT) con la respuesta fisiológica y el rendimiento en corredores de fondo entrenados. La prescripción de entrenamiento de HIIT generalmente se realiza usando un enfoque empírico común y estandarizado, en el que los corredores de un nivel similar entrenan juntos usando el mismo esquema HIIT. Sin embargo, estudios previos mostraron que es posible enfocarse en algunas adaptaciones fisiológicas individualizando las prescripciones de HIIT acorde con las características fisiológicas de los corredores y sus respuestas al ejercicio. Esto puede estar relacionado al mayor tiempo pasado en (o cerca del) V̇ O2max y, por lo tanto, al estímulo cardiorrespiratorio más fuerte que se produce con este modelo de prescripción de entrenamiento. Dado que, en el enfoque estandarizado, en el que la velocidad es la misma para todos, los corredores que caen fuera del rango de intensidad deseado pueden producirse menores ganancias (o nulas) en la aptitud cardiorrespiratoria, se puede observar un efecto promedio de grupo más pequeño junto con una mayor heterogeneidad del efecto de entrenamiento.

- Abstract
208 p., El análisis del entrenamiento para deportes de resistencia es un tema que se ha estudiado cada vez más en la literatura durante la última década. A medida que la tecnología ha mejorado y los medios para monitorear el entrenamiento han aumentado, han surgido los conceptos de distribución de la intensidad del entrenamiento (TID) y la periodización. La distribución de la intensidad del entrenamiento se refiere a la proporción de entrenamiento realizado en diferentes niveles de intensidad. Estas zonas han sido delineadas por varios métodos, más comunmente umbrales de lactato/ventilación. Tradicionalmente se han descrito 3 zonas: Polarizado, Piraminal y Umbral. En los últimos años, la recomendación de un TID de tipo polarizado ha ganado popularidad debido a la investigación que demuestra sus efectos positivos sobre los determinantes fisiológicos asociados con el rendimiento de resistencia.Sin embargo, se observó que los mejores atletas del mundo entrenaban de una manera contraria a esta afirmación y esta tesis se propuso examinar esta aparente contradicción; determinar si este era realmente el caso y luego intentar comprender las razones. También presentamos un método novedoso para crear zonas de intensidad de entrenamiento, basado en el porcentaje del ritmo de carrera objetivo, que sentimos que refleja algunas de las prácticas empleadas por los mejores entrenadores y atletas del mundo. La tesis comienza con una revisión sistemática, cuyo objetivo es examinar la evidencia actual de tres tipos principales de distribución de la intensidad del entrenamiento: 1) Entrenamiento piramidal, 2) Entrenamiento polarizado y 3) Entrenamiento de umbral. Según los resultados de este análisis, el entrenamiento piramidal y polarizado son más efectivos que el entrenamiento de umbral, aunque este último es utilizado por algunos de los mejores corredores de maratón del mundo. A pesar de estos hallazgos aparentemente contradictorios, esta revisión presenta evidencia para la organización del

Purpose: To analyze the association between muscle activation patterns on oxygen cost of transport in elite race walkers over the entire gait waveform. Methods: A total of 21 Olympic race walkers performed overground walking trials at 14 km·h
-1 where muscle activity of the gluteus maximus, adductor magnus, rectus femoris, biceps femoris, medial gastrocnemius, and tibialis anterior were recorded. Race walking economy was determined by performing an incremental treadmill test ending at 14 km·h-1 . Results: This study found that more-economical race walkers exhibit greater gluteus maximus (P = .022, r = .716), biceps femoris (P = .011, r = .801), and medial gastrocnemius (P = .041, r = .662) activation prior to initial contact and weight acceptance. In addition, during the propulsive and the early swing phase, race walkers with higher activation of the rectus femoris (P = .021, r = .798) exhibited better race walking economy. Conclusions: This study suggests that the neuromuscular system is optimally coordinated through varying muscle activation to reduce the metabolic demand of race walking. These findings highlight the importance of proximal posterior muscle activation during initial contact and hip-flexor activation during early swing phase, which are associated with efficient energy transfer. Practically, race walking coaches may find this information useful in the development of specific training strategies on technique. [ABSTRACT FROM AUTHOR]- Published

Context: It is debated whether running biomechanics make good predictors of running economy, with little known about the neuromuscular and joint-stiffness contributions to economical running gait. Purpose: To understand the relationship between certain neuromuscular and spatiotemporal biomechanical factors associated with running economy. Methods: Thirty trained runners performed a 6-min constant-speed running set at 3.3 m·s
−1 , where oxygen consumption was assessed. Overground running trials were also performed at 3.3 m·s−1 to assess kinematics, kinetics, and muscle activity. Spatiotemporal gait variables, joint stiffness, preactivation, and stance-phase muscle activity (gluteus medius, rectus femoris, biceps femoris, peroneus longus, tibialis anterior, and gastrocnemius lateralis and medius) were variables of specific interest and thus determined. In addition, preactivation and ground contact of agonist–antagonist coactivation were calculated. Results: More economical runners presented with short ground-contact times (r =.639, P <.001) and greater stride frequencies (r = −.630, P <.001). Lower ankle and greater knee stiffness were associated with lower oxygen consumption (r =.527, P =.007 and r =.384, P =.043, respectively). Only lateral gastrocnemius–tibialis anterior coactivation during stance was associated with lower oxygen cost of transport (r =.672, P <.0001). Conclusions: Greater muscle preactivation and biarticular muscle activity during stance were associated with more economical runners. Consequently, trained runners who exhibit greater neuromuscular activation prior to and during ground contact, in turn optimizing spatiotemporal variables and joint stiffness, will be the most economical runners.

Where possible, the training intensity zones relative to the goal race pace, rather than physiological or subjective variables, were calculated. Three electronic databases (PubMed, Scopus, and Web of Science) were searched in May 2017 for original research articles. After analysis of 493 resultant original articles, studies were included if they met the following criteria: (1) Their participants were middle- or long-distance runners; (2) they analyzed training intensity distribution in the form of observational reports, case studies, or interventions; (3) they were published in peer-reviewed journals; and (4) they analyzed training programs with a duration of 4 wk or longer. Sixteen studies met the inclusion criteria, which included 6 observational reports, 3 case studies, 6 interventions, and 1 review. According to the results of this analysis, pyramidal and polarized training are more effective than threshold training, although the latest is used by some of the best marathon runners in the world. Despite this apparent contradictory finding, this review presents evidence for the organization of training into zones based on a percentage of goal race pace, which allows for different periodization types to be compatible. This approach requires further development to assess whether specific percentages above and below race pace are key to inducing optimal changes. [ABSTRACT FROM AUTHOR]

Advanced footwear technology (AFT) changed footwear design concepts by using a curved carbon fibre plate in combination with new, more compliant and resilient foams. The aim of this study was (1) to examine the individual effects of AFT on the evolution of the main road events and (2) to re-assess the impact of AFT on the world's top-100 performance in men's 10k, half-marathon and marathon events. Data from the top-100 men's 10k, half-marathon and marathon performances were collected between 2015 and 2019. The shoes used by the athletes were identified in 93.1% of the cases by publicly available photographs. Runners wearing AFT had an average performance of 1671 ± 22.28 s compared to 1685 ± 18.97 s of runners not using AFT in 10k (0.83%) (p < 0.001), 3589 ± 29.79 s compared to 3607 ± 30.49 s in half-marathon (0.50%) (p < 0.001) and 7563 ± 86.10 s compared to 7637 ± 72.51 s in the marathon (0.97%) (p < 0.001). Runners wearing AFTs were faster by ~1% in the main road events compared to non-users. Individual analysis showed that ~25% of the runners did not benefit from the use of this type of footwear. The results of this study suggest that AFT has a clear positive impact on running performance in main road events. [ABSTRACT FROM AUTHOR]

This study aimed to address the effects of increased longitudinal bending stiffness (LBS) on running economy (RE) and running biomechanics. A systematic search on four electronic databases (Pubmed, WOS, Medline and Scopus) was conducted on 26 May 2021. Twelve studies met the inclusion criteria and were included. Standardised mean difference with 95% confidence intervals (CI) between footwear with increased LBS vs. non-increased LBS conditions and effect sizes were calculated. To assess the potential effects of moderator variables (type and length plate, increased LBS, shoe mass and running speed) on the main outcome variable (i.e. RE), subgroup analyses were performed. Increased LBS improved RE (SMD = −0.43 [95% CI −0.58, −0.28], Z = 5.60, p < 0.001) compared to non-increased LBS. Significant increases of stride length (SMD = 0.29 [95% CI 0.10, 0.49], Z = 2.93, p = 0.003) and contact time (SMD = 0.17 [95% CI 0.03, 0.31], Z = 2.32, p = 0.02) were found when LBS was increased. RE improved to a greater degree at higher running speeds with footwear with increased LBS. RE improved 3.45% with curve plate compared to no-plate condition without improvements with flat plate shoes. When shoe mass was matched between footwear with increased LBS vs. non-increased LBS conditions, RE improved (3.15%). However, when shoe mass was not controlled (experimental condition with ∼35 grams extra), a significant small improvement was found. These RE improvements appear along with an increase of stride length and contact time. Shoe mass, type of plate (flat or curve) and running speed should be taken into consideration when designing a shoe aimed at improving long-distance running performance. [ABSTRACT FROM AUTHOR]
