Reliability and validity of a pool-based maximal oxygen uptake test to examine high-intensity short-duration freestyle swimming performance. J Strength Cond Res 33(5): 1208-1215, 2019-A modality-specific swimming protocol to assess maximal oxygen uptake (V[Combining Dot Above]O2maxsw) is essential to accurately prescribe and monitor swimming conditioning programs. Consequently, there is a need for a reliable and valid graded intensity swimming pool test to accurately assess V[Combining Dot Above]O2maxsw using indirect calorimetry. The purpose of this study was to assess (a) reliability of an intensity self-regulated swimming pool test of V[Combining Dot Above]O2maxsw and (b) validity of a V[Combining Dot Above]O2maxsw test using performance swim (PS) time as the criterion. Twenty-nine men (n = 15) and women (n = 14) (age, 23 ± 6.4 years; body mass index, 23.5 ± 3.0 kg·m) performed 2 swimming pool V[Combining Dot Above]O2maxsw trials (V[Combining Dot Above]O2maxsw A and V[Combining Dot Above]O2maxsw B), and 2 PS tests (45.7 m [31.20 ± 4.5 seconds] and 182 m [159.2 ± 25.5 seconds]). For test-retest reliability (trials A vs. B), strong correlations (p < 0.05) were found for V[Combining Dot Above]O2maxsw (ml·kg·min) (r = 0.899), O2 pulse (ml O2·beat) (r = 0.833), and maximum expired ventilatory volume (L·min) (r = 0.785). For performance validity, moderately strong correlations (p < 0.05) were found between V[Combining Dot Above]O2maxsw A and 45.7-m (r = -0.543) and 182-m (r = -0.486) swim times. The self-regulated graded intensity swimming pool protocol examined presently is a reliable and valid test of V[Combining Dot Above]O2maxsw. Studies should consider the suitability of a V[Combining Dot Above]O2maxsw test for military personnel, clinical populations, and injured athletes.
内格尔,EF,长谷川,T,贝特,AZ,洛韦卡,MT,泽拉,JN,康纳博伊,C,阿巴特,JP,比尔斯,K,尼丁,BC,罗伯逊,RJ 和莱法特,SM。一种基于泳池的最大摄氧量测试来检测高强度短时间自由泳表现的可靠性和有效性。J 力量与调节研究 33(5):1208-1215,2019-一种专门用于评估最大摄氧量(V[组合点上方]O2maxsw)的游泳模式是准确规定和监测游泳适应计划所必需的。因此,需要一种可靠且有效的分级强度泳池测试,以便使用间接热量法准确评估 V[组合点上方]O2maxsw。本研究的目的是评估 (a) 自我调节泳池 V[组合点上方]O2maxsw 强度测试的可靠性和 (b) 使用性能游泳(PS)时间作为标准的 V[组合点上方]O2maxsw 测试的有效性。29 名男性(n = 15)和女性(n = 14)(年龄,23 ± 6.4 岁;体重指数,23.5 ± 3.0 kg·m)进行了 2 次泳池 V[组合点上方]O2maxsw 试验(V[组合点上方]O2maxsw A 和 V[组合点上方]O2maxsw B)和 2 次 PS 测试(45.7 m [31.20 ± 4.5 秒]和 182 m [159.2 ± 25.5 秒])。对于测试-重测可靠性(试验 A 与 B),发现 V[组合点上方]O2maxsw(ml·kg·min)(r = 0.899)、O2 脉冲(ml O2·beat)(r = 0.833)和最大呼气量(L·min)(r = 0.785)之间存在强相关性(p < 0.05)。对于性能有效性,发现 V[组合点上方]O2maxsw A 与 45.7-m(r = -0.543)和 182-m(r = -0.486)游泳时间之间存在中度强相关性(p < 0.05)。目前检查的自我调节分级强度泳池方案是一种可靠且有效的 V[组合点上方]O2maxsw 测试。研究应考虑 V[组合点上方]O2maxsw 测试对军人、临床人群和受伤运动员的适用性。
