Shuttle versus straight repeated-sprint ability tests and their relationship to anthropometrics and explosive muscular performance in elite handball players.

摘要: BACKGROUND This study assessed inter-relationships between shuttle and straight repeated-sprint ability tests the relationship of each measure to anthropometric explosive lower limb performance data in elite handball players. METHODS Twenty-two male players (18.9±0.2 years; body mass: 83.3±1.1 kg, height: 1.79±2.30 m, fat: 12.8±0.2%) completed that included a force-velocity test peak power (Wpeak), jumping (squat counter-movement jumps; SJ, CMJ), 1 repetition maximum (1-RM) half back squat, average sprint velocity over 5 m (V-5 m), 25-30 (Vmax), Yo-Yo Intermittent Recovery Test level (Yo-Yo IR1), determinations cross-sectional areas muscle volumes for leg thigh muscles. Data were compared with on two repeated tests; (6 × 30 [RSA30]) intermittent (6×[2×15 m] sprints [RSA15]). RESULTS V-5 1-RM, showed relevant relationships RSA (r2≥0.5). The IR1 explained largest percentage variance RSA15 total time (60%), also 56% time. RSA15% fatigue was only related 1-RM (explained variance: 58%), RSA30 no useful correlations any investigated predictors. Multiple-regression analyses using all physical 91% (P<0.001). CONCLUSIONS volume muscles seems important production distances 15 or less. is muscular power, maximal strength, speed endurance performance; however, not, thus does not seem testing
