Klein, IE, White, JB, and Rana, SR. Comparison of physiological variables between the elliptical bicycle and run training in experienced runners. J Strength Cond Res 30(11): 2998-3006, 2016-A novel outdoor elliptical bicycle (EBIKE) has been designed to elicit running-similar physiological adaptations while reducing the impact forces that commonly lead to injury. Various cross-training methods have been used to reduce injury risk, restore or maintain fitness, and prevent detraining. The purpose of this study was to compare 4 weeks of EBIKE-only training to run-only training on maximal oxygen consumption, ventilatory threshold, respiratory compensation point, running economy, and 5,000 m time trial times. Twelve experienced runners (age, 22.33 ± 3.33 years; running experience, 9.25 ± 4.53 years) completed 4 weeks of randomly assigned EBIKE or run training. Physiological and performance testing procedures were repeated, and subjects then performed a second matched 4-week training period in a crossover design. Ventilatory threshold was significantly greater after EBIKE (p ≤ 0.05; 41.60 ± 6.15 ml·kg·min) and run training (p ≤ 0.05; 42.33 ± 6.96 ml·kg·min) compared with the initial time point (40.17 ± 6.47 ml·kg·min). There were no significant group differences (p > 0.05) for these variables at any time point. In conclusion, EBIKE-only training yielded similar physiological and performance maintenance or improvements compared with run-only training. These results suggest that EBIKE training can be an effective cross-training method to maintain and improve certain physiological and performance variables in experienced runners over a 4-week period.
克莱因，IE，怀特，JB，以及拉纳，SR。有经验的跑步者在椭圆自行车训练和跑步训练之间生理变量的比较。《力量与体能研究杂志》30(11): 2998 - 3006，2016年——一种新型户外椭圆自行车（EBIKE）已被设计出来，旨在引发与跑步相似的生理适应，同时减少通常会导致受伤的冲击力。各种交叉训练方法已被用于降低受伤风险、恢复或保持体能以及防止体能下降。本研究的目的是比较仅进行4周椭圆自行车训练与仅进行跑步训练对最大摄氧量、通气阈值、呼吸补偿点、跑步经济性以及5000米计时赛成绩的影响。12名有经验的跑步者（年龄，22.33 ± 3.33岁；跑步经验，9.25 ± 4.53年）完成了4周随机分配的椭圆自行车训练或跑步训练。重复进行生理和性能测试程序，然后受试者在交叉设计中进行第二个为期4周的匹配训练期。与初始时间点（40.17 ± 6.47毫升·千克·分钟）相比，椭圆自行车训练（p≤0.05；41.60 ± 6.15毫升·千克·分钟）和跑步训练（p≤0.05；42.33 ± 6.96毫升·千克·分钟）后的通气阈值显著更高。在任何时间点，这些变量在两组之间均无显著差异（p > 0.05）。总之，与仅进行跑步训练相比，仅进行椭圆自行车训练在生理和性能维持或改善方面产生了相似的效果。这些结果表明，在4周时间内，椭圆自行车训练可以成为一种有效的交叉训练方法，用于维持和改善有经验的跑步者的某些生理和性能变量。
