The goal of the present study was to explore Primary Education students’ views on their involvement in a three pedagogical models’ hybridization (Health-Based Physical Education, Cooperative Learni...
Neuromuscular and cardiovascular adaptations during concurrent strength and endurance training in untrained men.
2012
This study examined the effects of concurrent strength and endurance training on neuromuscular and endurance characteristics compared to strength or endurance training alone. Previously untrained men were divided into strength (S: n=16), endurance (E: n=11) or concurrent strength and endurance (SE: n=11) training groups. S and E trained 2 times and SE 2 + 2 times a week for strength and endurance during the 21-week period. Maximal unilateral isometric and bilateral concentric forces of leg muscles increased similarly in S and SE by 20-28% (p<0.01) and improvements in isometric forces were accompanied by increases (p<0.05) of maximal muscle activation. Rate of force development of isometric …
Réponses cardiovasculaires lors de la distribution du courrier postal avec un vélo à assistance électrique
2010
Cette etude a evalue les reponses cardiovasculaires lors de la distribution du courrier postal. Vingt-deux facteurs ont ete testes sur deux journees de travail, l’une realisee avec un velo electrique (VE), l’autre avec un velo traditionnel (VT). Les resultats ont montre une diminution significative (p < 0,05) de la frequence cardiaque moyenne avec l’utilisation d’un VE (90 ± 15 bpm) en comparaison d’un VT (94 ± 14 bpm), dont l’importance semble dependante du type de tournee realisee (type Pavillon vs. type Centre-ville). La duree de travail (≈ 660 min) et la depense energetique (≈ 330 Kcal) n’etaient pas affectees par le type de velo utilise. Le VE semble donc etre une alternative interessa…
Differences in gender and performance in off-road triathlon.
2010
The aims of this study were: (1) to examine performance trends and compare elite male and female athletes at the off-road triathlon (1.5-km swim, 30-km mountain biking, and 11-km trail running) world championships since its inception in 1996, and (2) to compare gender-related differences between off-road triathlon and conventional road-based triathlon. Linear regression analyses and ANOVA were used to examine performance trends and differences between the sexes. Elite male performance times stabilized over the 2005-2009 period, whereas elite female performance times continued to improve, especially for the run leg. Differences in performance times between the sexes were less marked in swimm…
Effects of Stretching on Upper-Body Muscular Performance
2008
The purpose of this investigation was to examine the influence of upper-body static stretching and dynamic stretching on upper-body muscular performance. Eleven healthy men, who were National Collegiate Athletic Association Division I track and field athletes (age, 19.6 +/- 1.7 years; body mass, 93.7 +/- 13.8 kg; height, 183.6 +/- 4.6 cm; bench press 1 repetition maximum [1RM], 106.2 +/- 23.0 kg), participated in this study. Over 4 sessions, subjects participated in 4 different stretching protocols (i.e., no stretching, static stretching, dynamic stretching, and combined static and dynamic stretching) in a balanced randomized order followed by 4 tests: 30% of 1 RM bench throw, isometric ben…
The effects of the Nordic hamstring exercise on sprint performance and eccentric knee flexor strength: A systematic review and meta-analysis of inter…
2021
Objectives: The primary aim of this study was to investigate the effects of the Nordic hamstring exercise (NHE) on sprint performance (i.e., 5, 10 and 20 m) and explore associations between study characteristics and sprint outcomes in team sport players. Secondary aims were to (1) investigate the effects of the NHE on eccentric strength of the knee flexors (ESKF) with categorical subgroup analysis to determine differences between recreationally, well-trained individuals and young athletes, (2) determine the relation between ESKF and sprint performance in team sport players, and (3) explore the effect of study characteristics (i.e., weekly volume, time duration and body mass) on ESKF.Methods…
Psychometric Evaluation of the Norwegian Versions of the Modified Group Environment Questionnaire and the Youth Sport Environment Questionnaire
2021
This study aimed to translate the modified Group Environment Questionnaire (GEQ) and the Youth Sport Environment Questionnaire (YSEQ) into Norwegian, examine the factor structure and reliability of the scales through independent clusters model confirmatory factor analysis (ICM-CFA) and exploratory structural equation modeling (ESEM), and examine differential item functioning (DIF) as a function of sex. Three-hundred-and-thirty-three athletes (M(SD)age = 18.7(2.60) years; 33% females) completed the GEQ. Three-hundred-and-three athletes (M(SD)age = 15.0(1.48) years; 26% females) completed the YSEQ. Results indicated acceptable fit indices for a four-factor, a second-order two-factor (task a…
Últimas Tendencias en el Análisis Técnico-Táctico del Voleibol de Alto Nivel. Revisión Sistemática (Latest Trends in Technical-Tactical Analysis of H…
2022
El análisis técnico-táctico se ha convertido en una pieza clave en el rendimiento del voleibol. Por tal motivo, el objetivo de esta revisión sistemática fue profundizar en las últimas tendencias de investigación aplicadas al análisis técnico-táctico del voleibol de alto nivel. Para ello, se llevó a cabo una revisión sistemática de la literatura siguiendo los criterios PRISMA, en el mes de febrero de 2022. Las bases de datos consultadas fueron SPORTDiscus, Web of Science y Scopus. Como resultado se obtuvieron un total de 1087 artículos, de los cuales finalmente 45 formaron parte de la revisión. Se identificaron tres tipos de variables independientes relacionadas con: el contexto social (rank…
Effect of total knee replacement surgery and postoperative 12 month home exercise program on gait parameters
2017
Abstract Objective To evaluate the effects of surgery and a postoperative progressive home exercise program on gait parameters among individuals operated with total knee arthroplasty. Design Single blinded randomized controlled trial. Subjects 108 patients (84 females, 24 males, mean age 69 years). Interventions Patients were equally randomized into an exercise group (EG) and control group (CG). The 12-months progressive home exercise program starting two months postoperatively was compared to usual care. Methods Gait analysis was performed using the Gaitrite electronic walkway system. In addition, knee extension and flexion strength were measured by a dynamometer preoperatively, and pain o…
