The purpose of this study was to examine the reliability and sensitivity of 3 ecologically valid repeated high-intensity exercise (RHIE) tests for professional rugby league (RL) and rugby union (RU) players. A further purpose was to investigate the relationship between RHIE performance and measures of speed (20-m sprint) and high-intensity intermittent running ability (yo-yo intermittent recovery test). Thirty-six RU and RL players were separated into 3 equal groups based on playing position: backs, RL forwards and RU forwards. Test-retest reliability was assessed by comparing total sprint time over 9 sprints during 2 identical testing sessions. The intraclass correlation coefficients (ICCs) for total sprint time were moderate to high (0.82, 0.97, and 0.94) and coefficient of variation (CV) low (4.2, 1.4, and 0.6%) for the backs, RL forwards, and RU forwards tests, respectively. However, sprint performance decrement scores were poorer, with ICC and CV of 0.78, 0.86, and 0.88 and 49.5, 48.2, and 35.8% for the backs, RL forwards, and RU forwards, respectively. Total sprint times for the backs, RL forwards, and RU forwards decreased over the 3 tests by 0.54, 0.53, and 2.09 seconds, respectively. Changes in RHIE total sprint time were moderately related to changes in 20-m sprint times (T1 to T2, r = 0.63; T2 to T3, r = 0.69; and T1 to T3, r = 0.63; all p < 0.05) but not yo-yo intermittent recovery test performances. This study has shown that the designed RL and RU RHIE tests have moderate to high reliability and produce significant improvements over a training period when total sprint times are compared.
本研究旨在检验 3 项具有生态效度的重复性高强度运动(RHIE)测试在职业英式橄榄球联盟(RL)和橄榄球联盟(RU)运动员中的可靠性和敏感性。进一步的目的是研究 RHIE 表现与速度(20 米冲刺)和高强度间歇跑步能力(Yo-Yo 间歇恢复测试)测量值之间的关系。36 名 RU 和 RL 运动员根据场上位置分为 3 个相等的组:后卫、RL 前锋和 RU 前锋。通过比较 2 次相同测试中 9 次冲刺的总冲刺时间来评估测试-重测可靠性。总冲刺时间的组内相关系数(ICC)为中度至高度(0.82、0.97 和 0.94),变异系数(CV)低(4.2%、1.4%和 0.6%),分别适用于后卫、RL 前锋和 RU 前锋测试。然而,冲刺表现下降得分较差,ICC 和 CV 分别为 0.78、0.86 和 0.88,以及 49.5%、48.2%和 35.8%,适用于后卫、RL 前锋和 RU 前锋。3 次测试中,后卫、RL 前锋和 RU 前锋的总冲刺时间分别减少了 0.54、0.53 和 2.09 秒。RHIE 总冲刺时间的变化与 20 米冲刺时间的变化中度相关(T1 到 T2,r = 0.63;T2 到 T3,r = 0.69;T1 到 T3,r = 0.63;所有 p < 0.05),但与 Yo-Yo 间歇恢复测试成绩无关。本研究表明,设计的 RL 和 RU RHIE 测试具有中度至高度的可靠性,当比较总冲刺时间时,在训练期间会产生显著的提高。
