Abstract

OBJECTIVE: Our objective was to explore the training-related knowledge, beliefs, and practices of athletes and the influence of lockdowns in response to the coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: Athletes (n = 12,526, comprising 13% world class, 21% international, 36% national, 24% state, and 6% recreational) completed an online survey that was available from 17 May to 5 July 2020 and explored their training behaviors (training knowledge, beliefs/attitudes, and practices), including specific questions on their training intensity, frequency, and session duration before and during lockdown (March-June 2020). RESULTS: Overall, 85% of athletes wanted to "maintain training," and 79% disagreed with the statement that it is "okay to not train during lockdown," with a greater prevalence for both in higher-level athletes. In total, 60% of athletes considered "coaching by correspondence (remote coaching)" to be sufficient (highest amongst world-class athletes). During lockdown, < 40% were able to maintain sport-specific training (e.g., long endurance [39%], interval training [35%], weightlifting [33%], plyometric exercise [30%]) at pre-lockdown levels (higher among world-class, international, and national athletes), with most (83%) training for "general fitness and health maintenance" during lockdown. Athletes trained alone (80%) and focused on bodyweight (65%) and cardiovascular (59%) exercise/training during lockdown. Compared with before lockdown, most athletes reported reduced training frequency (from between five and seven sessions per week to four or fewer), shorter training sessions (from ≥ 60 to < 60 min), and lower sport-specific intensity (~ 38% reduction), irrespective of athlete classification. CONCLUSIONS: COVID-19-related lockdowns saw marked reductions in athletic training specificity, intensity, frequency, and duration, with notable within-sample differences (by athlete clas

Abstract

PURPOSE: To investigate differences in athletes' knowledge, beliefs, and training practices during COVID-19 lockdowns with reference to sport classification and sex. This work extends an initial descriptive evaluation focusing on athlete classification. METHODS: Athletes (12,526; 66% male; 142 countries) completed an online survey (May-July 2020) assessing knowledge, beliefs, and practices toward training. Sports were classified as team sports (45%), endurance (20%), power/technical (10%), combat (9%), aquatic (6%), recreational (4%), racquet (3%), precision (2%), parasports (1%), and others (1%). Further analysis by sex was performed. RESULTS: During lockdown, athletes practiced body-weight-based exercises routinely (67% females and 64% males), ranging from 50% (precision) to 78% (parasports). More sport-specific technical skills were performed in combat, parasports, and precision (∼50%) than other sports (∼35%). Most athletes (range: 50% [parasports] to 75% [endurance]) performed cardiorespiratory training (trivial sex differences). Compared to prelockdown, perceived training intensity was reduced by 29% to 41%, depending on sport (largest decline: ∼38% in team sports, unaffected by sex). Some athletes (range: 7%-49%) maintained their training intensity for strength, endurance, speed, plyometric, change-of-direction, and technical training. Athletes who previously trained ≥5 sessions per week reduced their volume (range: 18%-28%) during lockdown. The proportion of athletes (81%) training ≥60 min/session reduced by 31% to 43% during lockdown. Males and females had comparable moderate levels of training knowledge (56% vs 58%) and beliefs/attitudes (54% vs 56%). CONCLUSIONS: Changes in athletes' training practices were sport-specific, with few or no sex differences. Team-based sports were generally more susceptible to changes than individual sports. Policy makers should provide athletes with specific training arrangements and educational resources to facilitate remot

Abstract

Background. Evaluation of athletes is a key element of the training process. Although there are some judo-specific tests, none of them includes the main judo actions (gripping, throwing, and groundwork) in its structure. Problem and aim. To evaluate the reliability, usefulness and validity of a new judo physical fitness test (JPFT), which includes gripping, throwing, and groundwork actions. Methods: Ten male judo athletes (16.5 +/- 0.5 years, height = 181.0 +/- 7.7 cm, body mass = 78.3 +/- 11.5 kg) performed the JPFT twice, separated by 48 h. Validity was determined by examining the relationship between JPFT and the Wingate test, Special Judo Fitness Test (SJFT), simulated judo match (SJM) and incremental exercise test (IET). Results. All ICC values were statistically significant, except for the number of techniques in series A and the rating of perceived exertion (RPE, ) with two variables presenting significant reliability (resting blood lactate, [La], number of techniques in series B), six very significant reliability ([La] 5-min after the test, peak [La], heart rate, HR, 1-min after the test, number of techniques in series C, total number of techniques, JPFT index), and three nearly perfect reliability ([La] 3-min after the test, HR after the test, SJFT index). Large and very large correlations were observed between [La] and HR in the JPFT and those in the SJFT and SJM. The similarity of effort during an official match was correlated with [La] 5-min after the test (r= 0.84) and peak [La] (r= 0.71) and RPE (r= 0.68) to the JPFT.

Abstract

Background and Purpose - As a reliable scoring system to detect the risk of symptomatic intracerebral hemorrhage after thrombectomy for ischemic stroke is not yet available, we developed a nomogram for predicting symptomatic intracerebral hemorrhage in patients with large vessel occlusion in the anterior circulation who received bridging of thrombectomy with intravenous thrombolysis (training set), and to validate the model by using a cohort of patients treated with direct thrombectomy (test set). Methods - We conducted a cohort study on prospectively collected data from 3714 patients enrolled in the IER (Italian Registry of Endovascular Stroke Treatment in Acute Stroke). Symptomatic intracerebral hemorrhage was defined as any type of intracerebral hemorrhage with increase of ≥4 National Institutes of Health Stroke Scale score points from baseline ≤24 hours or death. Based on multivariate logistic models, the nomogram was generated. We assessed the discriminative performance by using the area under the receiver operating characteristic curve. Results - National Institutes of Health Stroke Scale score, onset-to-end procedure time, age, unsuccessful recanalization, and Careggi collateral score composed the IER-SICH nomogram. After removing Careggi collateral score from the first model, a second model including Alberta Stroke Program Early CT Score was developed. The area under the receiver operating characteristic curve of the IER-SICH nomogram was 0.778 in the training set (n=492) and 0.709 in the test set (n=399). The area under the receiver operating characteristic curve of the second model was 0.733 in the training set (n=988) and 0.685 in the test set (n=779). Conclusions - The IER-SICH nomogram is the first model developed and validated for predicting symptomatic intracerebral hemorrhage after thrombectomy. It may provide indications on early identification of patients for more or less postprocedural intensive management.

Abstract

Combat simulations have served as an alternative framework to study the cardiorespiratory demands of the activity in combat sports, but this setting imposes rule-restrictions that may compromise the competitiveness of the bouts. The aim of this study was to assess the cardiorespiratory responses to a full-contact taekwondo combat simulation using a safe and externally valid competitive setting. Twelve male national level taekwondo athletes visited the laboratory on two separate occasions. On the first visit, anthropometric and running cardiopulmonary exercise assessments were performed. In the following two to seven days, participants performed a full-contact combat simulation, using a specifically designed gas analyser protector. Oxygen uptake ([Formula: see text]), heart rate (HR) and capillary blood lactate measurements ([La-]) were obtained. Time-motion analysis was performed to compare activity profile. The simulation yielded broadly comparable activity profiles to those performed in competition, a mean [Formula: see text] of 36.6 ± 3.9 ml.kg-1.min-1 (73 ± 6% [Formula: see text]) and mean HR of 177 ± 10 beats.min-1 (93 ± 5% HRPEAK). A peak [Formula: see text] of 44.8 ± 5.0 ml.kg-1.min-1 (89 ± 5% [Formula: see text]), a peak heart rate of 190 ± 13 beats.min-1 (98 ± 3% HRmax) and peak [La-] of 12.3 ± 2.9 mmol.L-1 was elicited by the bouts. Regarding time-motion analysis, combat simulation presented a similar exchange time, a shorter preparation time and a longer exchange-preparation ratio. Taekwondo combats capturing the full-contact competitive elements of a bout elicit moderate to high cardiorespiratory demands on the competitors. These data are valuable to assist preparatory strategies within the sport.

Abstract

Objective: Judo is a combat sport characterized by high-intensity intermittent efforts. To suit high competitive demand, the training periodization should be adopted to improve judo athletes performance. Thus, the objective of the present study was to monitor the changes in different variables during judo training periodization. Method: Ten male adult judo athletes were evaluated 18 weeks apart, in the beginning of preparatory period and one week before the main competition of the competitive period. During this observational study, the variables considered were: body composition, upper and lower-body anaerobic power and capacity, lower-body muscle power, upper and lower-body aerobic power, maximal and strength endurance, and judo specific performance. Paired Student's t test was used to compare variables across periods. Results: In the end of this period, athletes presented a significant increase in upper-body anaerobic power (pre = 535 ± 74 W; post = 617 ± 81 W; 15%) and capacity (pre = 344 ± 29 W; post = 402 ± 38 W; 17%), lower-body anaerobic power (pre = 778 ± 77 W; post = 882 ± 130 W; 13%), isometric (pre = 31 ± 17 s; post = 43 ± 15 s; 39%) and dynamic grip strength endurance (pre = 7 ± 5 rep; post = 11 ± 5 rep; 57%), upper-body aerobic power (pre = 113 ± 25 W; post = 122 ± 29 W; 8%), and row 1RM (pre = 85 ± 23 kg; post = 92 ± 26 kg; 8%). The body composition, judo specific performance, handgrip strength, bench-press 1RM, row and bench-press number of repetitions at 70% 1RM, and lower-body muscle power were maintained. Athletes presented a decrease in lower-body aerobic power (pre = 235 ± 62 W; post = 209 ± 43 W; 11%). Conclusion: The results of the present study indicated that the changes during a periodized judo program were specific to the match demand, although not all variables improved across this period. Objetivo: El judo es un deporte de combate caracterizado por intervalos de esfuerzos de elevada intensidad. Para soportar la elevada demanda competitiva, la periodización del entrenamiento debe ser utilizada para mejorar el desempeño de los atletas de judo. Por tanto, el objetivo del presente estudio fue evaluar los cambios, en diferentes variables, durante la periodización del entrenamiento de judo. Método: Diez atletas de judo varones fueron evaluados con 18 semanas de intervalo, en el inicio del período preparatorio y una semana después de la principal competición del período competitivo. Durante este estudio observacional, las variables consideradas fueron: composición corporal, potencia y capacidad anaeróbica de miembros superiores e inferiores, potencia muscular de miembros inferiores, potencia aeróbica de miembros superiores e inferiores, fuerza máxima, resistencia de fuerza y la performance en un test específico para el judo. El test t de Student para datos pareados fue utilizado para comparar las variables durante el período de entrenamiento. Resultados: Al final de ese período, los atletas presentaron aumento significativo en la potencia (pre = 535 ± 74 W; post = 617 ± 81 W; 15%) y en la capacidad (pre = 344 ± 29 W; post = 402 ± 38 W; 17%) anaeróbicas de miembros superiores, potencia anaeróbica de miembros inferiores (pre = 778 ± 77 W; post = 882 ± 130 W; 13%), resistencia de fuerza isométrica (pre = 31 ± 17 s; post = 43 ± 15 s; 39%) y dinámica de golpeo (pre = 7 ± 5 rep; post = 11 ± 5 rep; 57%), potencia aeróbica de miembros superiores (pre = 113 ± 25 W; post = 122 ± 29 W; 8%), y fuerza máxima de l RM (pre = 85 ± 23 kg; post = 92 ± 26 kg; 8%). La composición corporal, el desempeño en el test específico, la fuerza de preensión manual, la fuerza máxima en el press de banca y de 1RM, el número de repeticiones en el press de banca a 70% 1RM y la potencia muscular de miembros inferiores no experimentaron cambios. Los atletas presentaron una disminución en la potencia aeróbica de miembros inferiores (pre = 235 ± 62 W; post = 209 ± 43 W; 11%). Conclusión: Los resultados indican que los cambios durante el ciclo del programa de entrenamiento de judo fueron específicos a la demanda del combate competitivo, aunque algunas variables no cambiarán en ese período. Objetivo: O judô é um esporte de combate caracterizado por esforços intermitentes de elevada intensidade. Para lidar com a demanda competitiva, a periodização do treinamento deve ser adotada para melhorar o desempenho de atletas de judô. Assim, o objetivo do presente estudo foi monitorar as mudanças em diferentes variáveis durante o treinamento periodizado de judô. Método: Dez atletas de judo adultos foram avaliados com intervalo de 18 semanas, no começo do período preparatório e uma semana antes da principal competição do período competitivo. Durante esse estudo observacional, as variáveis consideradas foram: composição corporal, potência e capacidade anaeróbias de membros superiores e inferiores, potência muscular de membros inferiores, potência aeróbia de membros superiores e inferiores, força máxima, resistência de força e desempenho específico do judô. O teste t de Student foi utilizado para comparar as variáveis entre os períodos. Resultados: Ao final deste período os atletas apresentaram aumento significante na potência (pré = 535 ± 74 W; pós = 617 ± 81 W; 15%) e capacidade anaeróbias de membros superiores (pré = 344 ± 29 W; pós = 402 ± 38 W; 17%), potência anaeróbia de membros inferiores (pré = 778 ± 77 W; pós = 882 ± 130 W; 13%), resistência de força isométrica de pegada (pré = 31 ± 17 s; pós = 43 ± 15 s; 39%), resistência de força dinâmica de pegada (pré = 7 ± 5 rep;pós = 11 ± 5 rep; 57%), potência aeróbia de membros superiores (pré = 113 ± 25 W; pós = 122 ± 29 W; 8%) e 1RM na remada (pré = 85 ± 23 kg; pós = 92 ± 26 kg; 8%). A composição corporal, o desempenho específico ao judô, a força máxima isométrica de preensão manual, o 1RM no supino, o número de repetições a 70% de 1RM na remada e no supino e a potência muscular de membros inferiores foram mantidas. Os atletas apresentaram decréscimo na potência aeróbia de membros inferiores (pré = 235 ± 62 W;pós = 209 ± 43 W; 11%). Conclusão: Os resultados do presente estudo indicam que as mudanças durante um programa periodizado de treinamento de judô foram específicas à demanda da luta, embora nem todas as variáveis tenham melhorado ao longo do período analisado.

Abstract

Human performance efficiency and effectiveness in different sports depend to a large extent on the size, weight and proportion of the physique of the athlete. The aim of this study was to identify morphological characteristics of Brazilian Jiu-Jitsu (BJJ) athletes. The sample consisted of 25 highly trained male athletes who were classified according to their fighting style; guard fighter (GF) vs. pass fighter (PF). The athletes were assessed for somatotype, body composition and proportionality. For the whole group of athletes the somatotype was 2.23±0.68, 6.33±1.14, and 1.75±0.87 for endomorph, mesomorph and ectomorph components, respectively. Muscle and adipose tissue percentages were 52.34±2.15% and 19.30±2.51%, respectively. PF were significantly more mesomorph (p< 0.05) and less ectomorph (p< 0.05) than GF. Also, PF had significantly higher phantom Z score for bone mass vs. GF (0.51±0.57 vs. 0.01±0.54; p

Abstract

Objetive. The acute effects of cryotherapy on creatine phosphokinase (CPK) and lactate dehydrogenase (LDH) expression, perceived pain and upper limb muscle strength in jiu-jitsu competitors were investigated. Method. Ten highly trained athletes underwent two simulated competition sessions composed by four 7-minute combats with a 15-minute interval between them. Athletes were randomly allocated to receive either cold water immersion (5 ± 1 °C for 19 minutes) or no intervention (control) after competition simulation in a crossover counterbalanced fashion. Results. For LDH, there was an effect of condition (F1,18= 7.91, P = 0.012; η2 = 0.31), with lower values being found in cryotherapy as compared to control (criotherapy = 533.2 ± 55.4 and 671.2 ± 61.0 for pre- competition and post-recuperation, respectively; control = 528.5 ± 63.7 e 759.8 ± 85.7 UI/l for pre- competition and post-recuperation, respectively). Delta CPK differed significantly between conditions (criotherapy = 138.0 ± 95.1 UI/l; control = 231.3 ± 135.8 UI/l t = -1,72; P = 0,119; effect size = 0.75). For perceived pain there was also an effect of condition (F1,18 = 12.35, P = 0.003; η2 = 0.41), with lower values being found following cryotherapy (2.4 ± 1.4 versus 4.4 ± 1.8, P = 0.003). Pre-competition skin temperature was lower than that measured after recovery (34.5 ± 1.9 ºC. versus 37.6 ± 1.3 ºC, P = 0.0005). There were significant correlations between perceived pain and CPK (r = 0.314) and LDH (r = 0.546). The concentrations of CPK and LDH were negatively correlated with dynamic strength (r = - 0.525). Conclusion. Recovery via cold water immersion after simulated competition resulted in less muscle damage and hypoalgesia compared to the control. Objetivo. Investigar los efectos agudos de la crioterapia en la expresión de la enzima creatina fosfoquinasa (CPK), lactato deshidrogenasa (LDH), percepción del dolor y fuerza muscular en los miembros superiores de competidores de jiu-jitsu. Método. Diez luchadores altamente entrenados fueron sometidos a dos sesiones de competición simulada (4 × 7-minutos y 15 minutos de intervalo). Después del primer día, cinco atletas fueron elegidos para la inmersión en piscina con hielo (5 ± 1 °C) durante 19 minutos, los demás fueron asignados al grupo control. Resultados. Para LDH se observó efecto de la condición (F1,18 = 7,91, P = 0,012; η² = 0,31) con valores más bajos (P = 0,012) en la crioterapia en comparación con el control (crioterapia = 533,2 ± 55,4 y 671,2 ± 61,0, respectivamente para inicial y final; control = 528,5 ± 63,7 y 759,8 ± 85,7 UI/l; respectivamente para inicial y final). El delta del CPK fue significativamente distinto entre las condiciones (crioterapia = 138,0 ± 95,1 UI/l; t = -1,72; P = 0,119; control = 231,3 ± 135,8 UI/l; tamaño del efecto = 0,75). Para el dolor percibido también hubo efecto de la condición (F1,18 = 12,35, P = 0,003; η² = 0,41) con valores más bajos (P = 0,003) en la crioterapia (2,4 ± 1,4 frente a 4,4 ± 1,8). La temperatura corporal posrecuperación fue más baja en grupo crioterapia (P = 0,005) que la obtenida después en el control (34,5 ± 1,9ºC frente a 37,6 ± 1,3ºC). Se encontró correlación significativa entre la percepción del dolor y las concentraciones de CPK (r = 0,314) y LDH (r = 0,546). Las concentraciones de CPK y LDH se correlacionaron negativamente con la fuerza dinámica (r = - 0,525). Conclusión. La recuperación usando la inmersión después de la competición resulta de un menor daño muscular e hipoalgesia.

Abstract

Trivariate Box-splines lack an efficient and general exact evaluation technique. This paper presents one possible and underexploited approach to solving this problem. The algorithm we propose is based on mixed directional differences and summations for computing the Bézier net coefficients of all trivariate four-direction Box-splines of any degree over tetrahedral tessellations of the domain. A Matlab package, called MDDS, for computing the Bézier net both in the trivariate and bivariate cases, is also provided.

Abstract

Objective: The aim of the present study was to examine the influence of karate practice level (national vs international level) and sex (women vs men) on physiological and perceptual responses in three modern karate training modalities (tactical-technical (TT), technical-development (TD), and randori). Method: The study included 18 karatekas participating in an eight-session training camp of four TT, two TD, and two randori. During each session, the percentage of maximal heart rate (HR), blood lactate concentration [La-], and rating of perceived exertion (RPE) were assessed. Results: The main results showed that the percentage of maximal HR was significantly higher in women than in men regardless of practice level or training modality (70.3 ± 4.1 vs 66.2 ± 6.3, respectively). Moreover, [La-] and RPE were significantly lower in international-level karatekas compared with their national-level counterparts whatever the sex or training modality ([La-] = 11.4 ± 2.6 vs 8.3 ± 2.4 mmol · L-1and RPE = 3.6 ± 1.2 vs 4.3 ± 1.5, respectively). Last, physiological and perceptual responses were significantly higher during randori in comparison with TT and TD for both sexes. Conclusion: The combination of [La-] and RPE thus seems to be a good indicator for discriminating between national- and international-level karatekas, and randori seems to be an effective means to reproduce official karate sparring.

Abstract

The aim of this study was to evaluate the performance, as well as neuromuscular activity, in a strength task in subjects with different training backgrounds. Participants (n = 26) were divided into three groups according to their training backgrounds (aerobic, strength or mixed) and submitted to three sessions: (1) determination of the maximum oxygen uptake during the incremental treadmill test to exhaustion and familiarization of the evaluation of maximum strength (1RM) for the half squat; (2) 1RM determination; and (3) strength exercise, four sets at 80% of the 1RM, in which the maximum number of repetitions (MNR), the total weight lifted (TWL), the root mean square (RMS) and median frequency (MF) of the electromyographic (EMG) activity for the second and last repetition were computed. There was an effect of group for MNR, with the aerobic group performing a higher MNR compared to the strength group (P = 0.045), and an effect on MF with a higher value in the second repetition than in the last repetition (P = 0.016). These results demonstrated that individuals with better aerobic fitness were more fatigue resistant than strength trained individuals. The absence of differences in EMG signals indicates that individuals with different training backgrounds have a similar pattern of motor unit recruitment during a resistance exercise performed until failure, and that the greater capacity to perform the MNR probably can be explained by peripheral adaptations.

Pocecco, E., Faulhaber, M., Franchini, E., and Burtscher, M.

Abstract

The aim of the present study was to compare performance and physiological responses during arm and leg aerobic power tests of combat duration in male child, cadet and senior judo athletes. Power output and physiological parameters, i.e., peak oxygen uptake (VO2peak), peak ventilation, peak heart rate, lactate, and rate of perceived exertion, of 7 child (under 15 years: age class U15, 12.7 ± 1.1 yrs), 10 cadet (U17, 14.9 ± 0.7 yrs) and 8 senior (+20, 29.3 ± 9.2 yrs) male judo athletes were assessed during incremental tests of combat duration on an arm crank and a cycle ergometer. Children as well as cadets demonstrated higher upper body relative VO2peak than seniors (37.3 ± 4.9, 39.2 ± 5.0 and 31.0 ± 2.1 ml∙kg-1∙min-1, respectively); moreover, upper and lower body relative VO2peak decreased with increasing age (r = -0.575, p < 0.003 and r = -0.580, p < 0.002, respectively). Children showed lower blood lactate concentrations after cranking as well as after cycling when compared to seniors (7.8 ± 2.4 vs. 11.4 ± 2.1 mmol∙l-1 and 7.9 ± 3.0 vs. 12.0 ± 1.9 mmol∙l-1, respectively); furthermore, blood lactate values after cranking increased with age (r = 0.473, p < 0.017). These differences should be considered in planning the training for judo athletes of different age classes. [ABSTRACT FROM AUTHOR]

Abstract

High dose chemo-radiotherapy followed by autologous bone marrow transplantation (ABMT) is known to be an effective treatment in stage IV neuroblastoma (NB). Since October '84, 19 children with NB (12 relapsed or resistant: Group A; 7 in first CR: Group B) received ablative therapy (AT) consisting of VCR (4 mg/mg), L-PAM (140 mg/mg) and fractionated TBI (1000 Rads). Induction strategy at diagnosis or at relapse included high dose Peptichemio, 2-3 cycles of Vincristine-Cyclophosphamide--high dose Platinum and surgery. Bone marrow was harvested after 2 evaluation proved negative by cytomorphology, histology and immunofluorescence. Mononuclear cells (median 6.7 x 10(7)/kg) were cryopreserved and reinfused without purging. At the time of AT in Group A8 children were in CR, 4 had minimal diseases; in Group B 6 were in CR and one in PR. One toxicity-related death occurred on day 7 in a child in first CR; median duration of granulocytopenia 0.5 x 10(9)/l and thrombocytopenia less than 50 x 10(9)/l were 20 days (R: 9-40) and 27 days (R: 11-51) respectively. Persistent immune thrombocytopenia occurred in 4 children. Fever higher tha 38 degrees C developed in all patients: sepsis was documented in 6 patients. Extramedullary toxicity was moderate: GI tract was the most affected. Two out of 5 children who received AT having residual disease achieved CR; relapse or progression of disease occurred in all these patients. Four out of 8 children in second or subsequent CR and 4 out of 5 in first CR are alive and well at 3-12 months (median 7).(ABSTRACT TRUNCATED AT 250 WORDS)
