An Assessment of the Hopping Strategy and Inter-Limb Asymmetry during the Triple Hop Test: A Test–Retest Pilot Study

The aims of the present study are to: (1) determine within- and between-session reliability multiple metrics obtained during triple hop test; (2) any systematic bias in both test inter-limb asymmetry scores for these metrics. Thirteen male young American football athletes performed three trials a on each leg two separate occasions. In addition to total distance hopped, manual detection touch down toe-off were calculated via video analysis, enabling flight time (for hop), ground contact (GCT), reactive strength index (RSI), stiffness (between hops) be calculated. Results showed all coefficient variation (CV) values ? 10.67% intraclass correlation coefficients (ICC) ranged from moderate excellent (0.53–0.95) sessions. Intrarater (CV 3.60%, ICC ? 0.97). No was evident between sessions raw (g = ?0.34 0.32) or magnitude ?0.19 0.43). However, ‘real’ changes (i.e., greater than CV session 1) an individual level For direction asymmetry, kappa revealed poor-to-fair levels agreement (K ?0.10 0.39), with exception first 0.69). These data show that, given inherent limitations jumped test, practitioners can confidently gather range reliable when computed manually, provided sufficient familiarization is conducted. addition, although appears only small sessions, limb dominance does appear fluctuate highlighting value also monitoring imbalance.
