This study compared the energy system contributions and relationship between mechanical and energy system variables in upper and lower body Wingate tests (WAnT) in judo athletes.
Eleven male judo athletes (18 ± 1 years, 174.3 ± 5.3 cm, 72.6 ± 9.9 kg, 11.8 ± 1.7% body fat) attended two laboratory sessions to perform two WAnT (upper and lower body) and two incremental tests (upper and lower body). The energy contributions of the oxidative, glycolytic, and phosphagen (ATP-PCr) systems were estimated based on oxygen consumption ( ) during WAnT, delta of lactate, and the fast phase of excess , respectively.
The upper and lower body presented similar results of oxidative (21 ± 4% vs 23 ± 3%) and ATP-PCr system contributions (29 ± 6% vs 32 ± 5%). The glycolytic system contribution (50 ± 5% vs 45 ± 4%) was higher in the upper body. The variance of mechanical variables in upper body was explained by glycolytic (R = 0.49-0.62) and oxidative systems (R = 0.44-0.49), whereas the variance of mechanical variables in lower body was explained by ATP-PCr (R = 0.41-0.55) and glycolytic systems (R = 0.62-0.94).
During WAnT, the glycolytic system presented the major energy contribution, being higher in the upper body. Moreover, mechanical and energy system variables presented a distinct relationship when comparing upper and lower body WAnT.
本研究比较了柔道运动员上下肢 Wingate 测试（WAnT）中能量系统的贡献以及力学和能量系统变量之间的关系。
11 名男性柔道运动员（18±1 岁，174.3±5.3cm，72.6±9.9kg，11.8±1.7%体脂）参加了两次实验室测试，进行了两次 WAnT（上下肢）和两次递增测试（上下肢）。基于 WAnT 期间的耗氧量（ ）、乳酸差值和快速相的 excess ，分别估计了氧化、糖酵解和磷酸原（ATP-Cr）系统的能量贡献。
上下肢的氧化（21±4%比 23±3%）和 ATP-Cr 系统贡献（29±6%比 32±5%）相似。上半身的糖酵解系统贡献（50±5%比 45±4%）更高。上半身的力学变量的方差可以用糖酵解（R=0.49-0.62）和氧化系统（R=0.44-0.49）来解释，而下半身的力学变量的方差可以用 ATP-Cr（R=0.41-0.55）和糖酵解系统（R=0.62-0.94）来解释。
在 WAnT 期间，糖酵解系统提供了主要的能量贡献，在上肢更高。此外，在比较上下肢 WAnT 时，力学和能量系统变量之间存在明显的关系。
