To verify the hypothesis that the peak power (PP) of a Wingate test (WT) is an underestimation of maximal power (P(max)) computed from the force-velocity test (FVT), to examine possible fatigue effect on P(max), and to investigate the effect of load on mean power (MP) and fatigue index (FI) during a WT in trained and recreational men.
Ten recreational (22.9 ± 1.7 y, 1.81 ± 0.06 m, 73.3 ± 10.4 kg) and 10 highly trained subjects (22.7 ± 1.4 y, 1.85 ± 0.05 m, 78.9 ± 6.6 kg) performed 2 WTs with 2 loads (8.7% and 11% of body mass [BM]) and an FVT on the same cycle ergometer, in randomized order.
Optimal load was equal to 10% BM in recreational participants. Given the quadratic relationship between load and power, the underestimation of P(max) was lower than 10% for the average values of trained and recreational participants with both loads. However, PP with a load equal to 8.7% BM was a large underestimation (~30%) of P(max) in the most powerful individuals. In addition, PP was not greater than P(max) of FVT for the same load. FI was independent of the load only if it was expressed relative to PP. The optimal load for MP during WT was close to the optimal load for PP.
The optimal load for WT performance should be approximately equal to 10% BM in recreational subjects. In powerful subjects, the FVT appears to be more appropriate in assessing maximal power, and loads higher than 11% BM should be verified for the WT.
验证以下假设,即温盖特测试(WT)的峰值功率(PP)低估了根据力-速度测试(FVT)计算得出的最大功率(P(max)),研究疲劳对P(max)的可能影响,并调查负荷对训练有素和业余男性进行WT期间平均功率(MP)和疲劳指数(FI)的影响。
10名业余受试者(22.9±1.7岁,身高1.81±0.06米,体重73.3±10.4千克)和10名训练有素的受试者(22.7±1.4岁,身高1.85±0.05米,体重78.9±6.6千克)在同一台自行车测功仪上,以随机顺序进行两次WT,负荷分别为体重(BM)的8.7%和11%,并进行一次FVT。
业余参与者的最佳负荷等于BM的10%。考虑到负荷与功率之间的二次关系,对于训练有素和业余参与者在两种负荷下的平均值,P(max)的低估低于10%。然而,对于最强壮的个体,负荷等于BM的8.7%时的PP对P(max)的低估幅度较大(约30%)。此外,相同负荷下PP不大于FVT的P(max)。仅当FI相对于PP表示时,它才与负荷无关。WT期间MP的最佳负荷接近PP的最佳负荷。
业余受试者进行WT的最佳负荷应约等于BM的10%。对于强壮的受试者,FVT似乎更适合评估最大功率,对于WT应验证高于BM的11%的负荷。
