本研究旨在评估30 s Wingate测试中时间和种族差异对肌肉力量和疲劳的影响。在一个随机的顺序，36名足球运动员- 12个黑色突尼斯人（BT），12个白色突尼斯人（WT），和12个南非人（SA）被要求在两个实验阶段，这是在08：00或17：00进行30-s温盖特测试。在每个测试阶段开始时，记录静息核心温度。在Wingate试验期间计算峰值（PP）和平均（MP）功率以及疲劳指数（FI）。在所有组中，核心温度、PP和MP均显著升高（p
The present study was designed to evaluate the effect of time-of-day and racial variation on muscle power and fatigue during a 30-s Wingate test. In a randomized order, 36 footballers - 12 black Tunisians (BT), 12 white Tunisians (WT), and 12 South Africans (SA) were asked to perform a 30-s Wingate test during two experimental sessions, which were either at 08:00 or 17:00h. At the beginning of each test session, resting core temperature was recorded. Peak (PP) and mean (MP) power as well as the fatigue index (FI) were calculated during the Wingate test. In all groups, core temperature, PP and MP were significantly higher (p
