Abstract

The purpose of this study was to evaluate the contribution of the 3 main energy pathways during a 30-second elliptical all-out test (EAT) compared with the Wingate all-out test (WAT). Participants were 12 male team sport players (age, 20.3 ± 1.8 years; body mass, 74.8 ± 12.4 kg; height, 176.0 ± 9.10 cm; body fat, 12.1 ± 1.0%). Net energy outputs from the oxidative, phospholytic, and glycolytic energy systems were calculated from oxygen uptake data recorded during 30-second test, the fast component of postexercise oxygen uptake kinetics, and peak blood lactate concentration, respectively. In addition, mechanical power indices were calculated. The main results showed that compared with WAT, EAT was characterized by significantly lower absolute and relative contributions of the oxidative system (16.9 ± 2.5 J vs. 19.8 ± 4.9 J; p ≤ 0.05 and 11.2 ± 1.5% vs. 15.7 ± 3.28%; p ≤ 0.001). In addition, significantly greater absolute and relative contributions of the phospholytic system (66.1 ± 15.8 J vs. 50.7 ± 15.9 J; p ≤ 0.01 and 43.8 ± 6.62% vs. 39.1 ± 6.87%; p ≤ 0.05) and a significantly greater absolute contribution of the glycolytic system (68.6 ± 18.4 J vs. 57.4 ± 13.7 J; p ≤ 0.01) were observed in EAT compared with WAT. Finally, all power indices, except the fatigue index, were significantly greater in EAT than WAT (p ≤ 0.05). Because of the significantly lower aerobic contribution in EAT compared with WAT, elliptical trainers may be a good alternative to cycle ergometers to assess anaerobic performance in athletes involved in whole-body activities.

摘要

本研究的目的是评估在30秒椭圆全力测试(EAT)期间与温盖特全力测试(WAT)相比,3种主要能量途径的贡献。参与者为12名男性团队运动运动员(年龄20.3±1.8岁;体重74.8±12.4千克;身高176.0±9.10厘米;体脂12.1±1.0%)。分别根据30秒测试期间记录的摄氧量数据、运动后摄氧量动力学的快速成分以及血乳酸峰值浓度,计算氧化、磷酸解和糖酵解能量系统的净能量输出。此外,还计算了机械功率指标。主要结果表明,与WAT相比,EAT的特点是氧化系统的绝对和相对贡献显著降低(16.9±2.5焦耳对19.8±4.9焦耳;p≤0.05,11.2±1.5%对15.7±3.28%;p≤0.001)。此外,与WAT相比,EAT中磷酸解系统的绝对和相对贡献显著更大(66.1±15.8焦耳对50.7±15.9焦耳;p≤0.01,43.8±6.62%对39.1±6.87%;p≤0.05),糖酵解系统的绝对贡献显著更大(68.6±18.4焦耳对57.4±13.7焦耳;p≤0.01)。最后,除疲劳指数外,EAT中的所有功率指标均显著高于WAT(p≤0.05)。由于与WAT相比,EAT中的有氧贡献显著降低,椭圆训练机可能是一种很好的替代自行车测力计的工具,用于评估参与全身活动的运动员的无氧性能。
