本研究的目的是调查反应强度指数（RSI）和最佳跌落高度（ODH）识别从多个跌落高度的日间可靠性。19名受过训练的男性投掷运动员（23.1 +/- 2.9岁，83.1 +/- 15.5 kg和182.5 +/- 4.89 cm）在间隔48小时的两次单独测试中，从4个递增的跌落高度（30、40、50和60 cm）完成了2次最大深度跳跃。用组内相关系数（ICC）和变异系数（CV）分析RSI和ODH的可靠性。RSI和ODH均表现出良好的可靠性，ICC >= 0.80（0.87和0.81），CV
The purpose of this study was to investigate the interday reliability of the reactive strength index (RSI) and optimal drop height (ODH) identification from multiple drop heights. Nineteen male trained hurling players (23.1 +/- 2.9 years, 83.1 +/- 15.5 kg, and 182.5 +/- 4.89 cm) completed 2 maximal depth jumps from 4 incremental drop heights (30, 40, 50, and 60 cm), over 2 separate testing sessions 48 hours apart. The RSI and ODH were analyzed for reliability using intraclass correlation coefficient (ICC) and coefficient of variation (CV). The RSI and ODH both demonstrated good reliability with ICC >= 0.80 (0.87 and 0.81) and CV
