Abstract

This study aimed to compare the V[Combining Dot Above]O2max and first and second ventilatory threshold (1stVT and 2ndVT) V[Combining Dot Above]O2 values and rating of perceived exertion (RPE) responses of treadmill running (TR) with those of 3 water aerobic exercises: stationary running (SR), jumping jack (JJ), and forward kick (FK). Nine women (22.89 ± 1.81 years, 1.66 ± 0.07 m, 58.46 ± 4.19 kg) performed 1 maximal test session for each of the 4 exercise protocols in a randomized order to determine the V[Combining Dot Above]O2max and V[Combining Dot Above]O2 values and RPE responses corresponding with the 1stVT and 2ndVT. V[Combining Dot Above]O2 values were also expressed as a percentage of V[Combining Dot Above]O2max (%V[Combining Dot Above]O2max). A repeated measures analysis of variance and Bonferroni's post hoc test were used, with α = 0.05 denoting statistical significance. The analyses showed that the V[Combining Dot Above]O2 responses were significantly higher for TR than for the other exercises at all effort intensities (V[Combining Dot Above]O2max: p < 0.001; 1stVT and 2ndVT V[Combining Dot Above]O2: p < 0.001), followed by intermediate responses for SR and FK and lower responses for JJ. However, no significant differences between exercises for values of %V[Combining Dot Above]O2max (1stVT: p = 0.099; 2ndVT: p = 0.131) and RPE (1stVT: p = 0.275; 2ndVT: p = 0.477) were found at submaximal intensities, indicating that it is possible to achieve and maintain the same training intensity with these exercises during a typical water fitness lesson. Moreover, the RPE values obtained for the 1stVT and 2ndVT can make the prescription of intensity for these water exercises for young women more simple and practical.

摘要

本研究旨在比较跑步机跑步(TR)与 3 种水上有氧运动(静止跑步(SR)、开合跳(JJ)和前踢(FK))的最大摄氧量(V[Combining Dot Above]O2max)和第一、第二通气阈(1stVT 和 2ndVT)的 V[Combining Dot Above]O2 值和主观用力感知(RPE)反应。9 名女性(22.89 ± 1.81 岁,1.66 ± 0.07 m,58.46 ± 4.19 kg)以随机顺序在每个运动方案中完成 1 次最大测试,以确定与 1stVT 和 2ndVT 相对应的 V[Combining Dot Above]O2max 和 V[Combining Dot Above]O2 值和 RPE 反应。V[Combining Dot Above]O2 值也表示为 V[Combining Dot Above]O2max 的百分比(%V[Combining Dot Above]O2max)。使用重复测量方差分析和 Bonferroni 事后检验,α=0.05 表示统计学意义。分析表明,在所有努力强度下,TR 的 V[Combining Dot Above]O2 反应均显著高于其他运动(V[Combining Dot Above]O2max:p < 0.001;1stVT 和 2ndVT V[Combining Dot Above]O2:p < 0.001),其次是 SR 和 FK 的中等反应,而 JJ 的反应较低。然而,在次最大强度下,各项运动的%V[Combining Dot Above]O2max 值(1stVT:p=0.099;2ndVT:p=0.131)和 RPE(1stVT:p=0.275;2ndVT:p=0.477)之间没有显著差异,这表明在典型的水上健身课程中,这些运动可以达到并保持相同的训练强度。此外,在这些水中运动中获得的 1stVT 和 2ndVT 的 RPE 值可以使年轻女性对这些运动强度的处方更加简单和实用。
