对卧床休息或太空飞行的适应伴随着直立运动能力的受损。我们假设每天30分钟的高强度间歇直立或仰卧对抗下体负压（LBNP）运动可以维持卧床休息后的直立运动心率和呼吸反应。24名男性（31+/-3岁）进行了5天的6度头部向下倾斜：8人不进行运动（CON）， 8人进行直立跑步机运动（UPex）， 8人进行仰卧跑步机运动，对抗LBNP -51.3+/-0.4 mm Hg （LBNPex）。在床前和床后分别测量亚极限跑步机运动反应（VO2peak的56%、74%和85%）。对照组患者卧床休息后亚最大心率、呼吸交换率、通气量显著增高（P<或= 0.05）。在UPex和LBNPex中，亚极限运动反应在床前和床后休息相似。我们的研究结果表明，每天30分钟的高强度间歇直立运动训练或针对LBNP的仰卧运动训练足以在卧床休息5天后维持直立运动反应。这些结果可能对航天飞行中运动对抗的发展具有重要意义。
Adaptation to bed rest or space flight is accompanied by an impaired ability to exercise in an upright position. We hypothesized that a daily, 30-min bout of intense, interval exercise in upright posture or supine against lower body negative pressure (LBNP) would maintain upright exercise heart rate and respiratory responses after bed rest. Twenty-four men (31+/-3 yr) underwent 5 d of 6 degree head-down tilt: eight performed no exercise (CON), eight performed upright treadmill exercise (UPex), and eight performed supine treadmill exercise against LBNP at-51.3+/-0.4 mm Hg (LBNPex). Submaximal treadmill exercise responses (56, 74, and 85% of VO2peak) were measured pre-and post-bed rest. In CON, submaximal heart rate, respiratory exchange ratio, and ventilation were significantly greater (P< or= 0.05) after bed rest. In UPex and LBNPex, submaximal exercise responses were similar pre-and post-bed rest. Our results indicate that a daily 30-min bout of intense, interval upright exercise training or supine exercise training against LBNP is sufficient to maintain upright exercise responses after 5 d of bed rest. These results may have important implications for the development of exercise countermeasures during space flight.
