The aim of this study was to evaluate the reliability and validity of a repeated modified agility test (RMAT) to assess anaerobic power and explosiveness. Twenty-seven subjects (age: 20.2 ± 0.9 years, body mass: 66.1 ± 6.0 kg, height: 176 ± 6 cm, and body fat: 11.4 ± 2.6%) participated in this study. After familiarization, subjects completed the RMAT consisting of 10 × 20-m maximal running performances (moving in forward, lateral, and backward) with ~25-second recovery between each run. Ten subjects performed the RMAT twice separated by at least 48 hours to evaluate relative and absolute reliability and usefulness of the test. The criterion validity of the RMAT was determined by examining the relationship between RMAT indices and the Wingate anaerobic test (WAT) performances and both vertical and horizontal jumps. Reliability of the total time (TT) and peak time (PT) of the RMAT was very good, with intraclass correlation coefficient > 0.90 and SEM < 5% and low bias. The usefulness of TT and PT of the RMAT was rated as "good" and "OK," respectively. The TT of the RMAT had significant correlations with the WAT (peak power: r = -0.44; mean power: r = -0.72), vertical jumps (squat jump: r = -0.50; countermovement jump: r = -0.61; drop jump (DJ): r = -0.55; DJ with dominant leg: r = -0.72; DJ with nondominant leg: r = -0.53) and 5 jump test (r = -0.56). These findings suggest that the RMAT is a reliable and valid test for assessing anaerobic power and explosiveness in multisprint sport athletes. Consequently, the RMAT is an easily applied, inexpensive field test and can provide coaches and strength and conditioning professionals with relevant information concerning the choice and the efficacy of training programs.
本研究旨在评估重复改良敏捷测试（RMAT）评估无氧能力和爆发力的可靠性和有效性。27 名受试者（年龄：20.2±0.9 岁，体重：66.1±6.0kg，身高：176±6cm，体脂：11.4±2.6%）参与了本研究。在熟悉之后，受试者完成了由 10×20m 最大跑步表现（向前、侧向和向后移动）组成的 RMAT，每次跑步之间有~25 秒的恢复期。10 名受试者至少相隔 48 小时进行两次 RMAT 测试，以评估测试的相对和绝对可靠性和有效性。RMAT 指数与无氧测试（Wingate 无氧测试，WAT）表现以及垂直和水平跳跃的关系确定了 RMAT 的效标效度。RMAT 的总时间（TT）和峰值时间（PT）的可靠性非常好，组内相关系数>0.90，SEM<5%，偏倚低。RMAT 的 TT 和 PT 的有用性分别被评为“好”和“尚可”。RMAT 的 TT 与 WAT（峰值功率：r=-0.44；平均功率：r=-0.72）、垂直跳跃（深蹲跳：r=-0.50；纵跳：r=-0.61；落跳（DJ）：r=-0.55；DJ 用优势腿：r=-0.72；DJ 用非优势腿：r=-0.53）和 5 跳测试（r=-0.56）显著相关。这些发现表明，RMAT 是一种可靠且有效的评估多冲刺运动运动员无氧能力和爆发力的测试方法。因此，RMAT 是一种易于应用、经济实惠的现场测试，可以为教练和力量与体能专业人员提供有关训练计划选择和效果的相关信息。
