A stationary start modification to the Wingate Anaerobic Test (WAnT) has become increasingly common. The aim of the present study was to determine whether the traditional 85 g kg(-1) body weight (BW) load (TRAD), or an individualized optimal load (OPT), is more suitable for obtaining peak and mean power outputs (PPO and MPO, respectively) for a stationary start.
Twelve recreationally active males and 10 females (mean age 30 ± 9.1 and 25 ± 5.5 years, respectively) completed three trials. The first determined the OPT load and included a familiarization of the 30-s stationary start test, followed by two randomized sessions testing the OPT and TRAD loads during the 30-s stationary start test on separate days. For each test, measures of power (watts), time, and cadence were collected to determine PPO, MPO, rate of power decline (rPD) and time to peak power (TtPP). All power data were corrected for flywheel moment of inertia.
Results revealed significant differences between OPT and TRAD load settings for males (95.1 ± 10.7 and 85.06 ± 0.40 g kg(-1) BW; p = 0.008) but not for females (84.71 ± 8.72 and 85.2 ± 0.61 g kg(-1) BW; p = 0.813). Relative PPO was not different for OPT or TRAD loads for males (p = 0.485) or females (p = 0.488).
It is not necessary to use an OPT load setting to acquire maximal PO for a 30-s cycle test using a stationary start. Instead, the traditional 85 g kg(-1) BW loading is suitable for both males and females.
对温盖特无氧试验（WAnT）进行静止起始修改的做法越来越普遍。本研究的目的是确定传统的85克/千克体重（BW）负荷（TRAD）或个性化的最佳负荷（OPT），哪一种更适合在静止起始时获得峰值功率输出和平均功率输出（分别为PPO和MPO）。
12名休闲运动男性和10名女性（平均年龄分别为30±9.1岁和25±5.5岁）完成了三项试验。第一项试验确定了最佳负荷，并包括一次30秒静止起始测试的熟悉过程，随后在不同日期进行两次随机测试，在30秒静止起始测试中分别测试最佳负荷和传统负荷。对于每次测试，收集功率（瓦特）、时间和踏频的测量值，以确定PPO、MPO、功率下降率（rPD）和达到峰值功率的时间（TtPP）。所有功率数据均根据飞轮转动惯量进行了校正。
结果显示，男性的最佳负荷和传统负荷设置之间存在显著差异（95.1±10.7和85.06±0.40克/千克体重；p = 0.008），但女性不存在显著差异（84.71±8.72和85.2±0.61克/千克体重；p = 0.813）。男性或女性的最佳负荷或传统负荷的相对PPO没有差异（男性：p = 0.485；女性：p = 0.488）。
对于使用静止起始的30秒周期测试，无需使用最佳负荷设置来获取最大功率输出。相反，传统的85克/千克体重负荷对男性和女性都适用。
