High intensity interval training (HIIT) is widely used to improve VO. The purpose of this study was to examine if lower extremity HIIT resulted in improved maximal oxygen uptake (VO) and peak power output (PPO) of the upper extremities. Twenty healthy and trained participants (11 female and 9 male, VO 3160±1175 ml/min) underwent a 6-week HIIT program of the lower extremities on a cycle ergometer. Before and after the training period a maximal cycle ergometry (CE) and a maximal hand crank ergometry (HCE) were conducted to determine VO and PPO. Additionally, hematological parameters were determined. Increases in VO of the lower extremities (3160±1175 to 3449±1231 ml/min, p<0.001, ηp=0.779) as well as of the upper extremities (2255±938 to 2377±1015 ml/min, p=0.010, ηp=0.356) from pre- to post-test were found. PPO of the lower extremities increased (243±95 to 257±93 W, p<0.001, ηp=0.491), whereas it remained unchanged for the upper extremities (103±50 to 108±54 W, p=0.209, ηp=0.150). All hematological parameters increased. The results demonstrate that VO of the upper extremities increased after 6-weeks of cycling HIIT. However, upper body PPO was unchanged.
高强度间歇训练（HIIT）广泛用于改善 VO。本研究旨在探讨下肢 HIIT 是否会提高上肢的最大摄氧量（VO）和最大功率输出（PPO）。20 名健康且训练有素的参与者（11 名女性和 9 名男性，VO 3160±1175ml/min）在周期测力计上进行了 6 周的下肢 HIIT 训练计划。在训练前后，进行了最大的自行车测力计（CE）和最大的手摇测力计（HCE），以确定 VO 和 PPO。此外，还确定了血液学参数。下肢 VO 的增加（3160±1175 至 3449±1231ml/min，p<0.001，ηp=0.779）以及上肢 VO 的增加（2255±938 至 2377±1015ml/min，p=0.010，ηp=0.356）从预测试到后测试。下肢 PPO 增加（243±95 至 257±93W，p<0.001，ηp=0.491），而上肢 PPO 保持不变（103±50 至 108±54W，p=0.209，ηp=0.150）。所有血液学参数均增加。结果表明，经过 6 周的自行车 HIIT 后，上肢 VO 增加。然而，上半身 PPO 没有变化。
