The purpose of this study was to determine the reliability and usefulness of the 30-15 Intermittent Fitness Test (30-15IFT) in professional male and female futsal players. Thirteen male (24.4 ± 5.6 years; 174.5 ± 10.3 cm; 70.3 ± 9.9 kg) and fourteen female (23.3 ± 4.5 years; 165.8 ± 6.2 cm; 61.7 ± 5.5 kg) professional futsal players performed the 30-15IFT on two occasions, separated by 5 days. Maximal intermittent running velocity (VIFT) and heart rate at exhaustion (HRpeak) data were collected for both tests. Reliability was assessed by the intraclass correlation coefficient (ICC), typical error (TE) expressed as a coefficient of variation (CV), and smallest worthwhile change (SWC). VIFT demonstrated very good reliability between sessions, both for male (ICC = 0.92) and female (ICC = 0.96) players. As the TE for VIFT and HRpeak was similar to the calculated SWC for both male and female players, the usefulness of the test was rated as "medium". A change in performance of at least 2 stages in male players, or a change of more than 1 stage in female players could be interpreted as a meaningful change in aerobic futsal fitness. The results of this study demonstrate that the 30-15IFT is both a reliable and useful test for male and female professional futsal players.
本研究的目的是确定30-15间歇体能测试（30-15IFT）在职业男女室内五人足球运动员中的可靠性和实用性。13名男性（24.4±5.6岁；174.5±10.3厘米；70.3±9.9千克）和14名女性（23.3±4.5岁；165.8±6.2厘米；61.7±5.5千克）职业室内五人足球运动员分两次进行30-15IFT测试，两次测试间隔5天。两次测试均收集了最大间歇跑步速度（VIFT）和力竭时心率（HRpeak）数据。通过组内相关系数（ICC）、以变异系数（CV）表示的典型误差（TE）和最小有意义变化（SWC）来评估可靠性。VIFT在男性（ICC = 0.92）和女性（ICC = 0.96）运动员的测试之间均显示出非常好的可靠性。由于VIFT和HRpeak的TE与男性和女性运动员计算出的SWC相似，该测试的实用性被评为“中等”。男性运动员至少2个阶段的表现变化，或女性运动员超过1个阶段的变化可被解释为室内五人足球有氧体能的有意义变化。本研究结果表明，30-15IFT对职业男女室内五人足球运动员来说是一项可靠且有用的测试。
