本研究旨在调查在 6 次头低位倾斜卧床休息 20 天期间，阻力训练对人体下肢 4 个肌肉群和/或 17 个单独肌肉的体积的影响。 12 名健康男性被分为两组：阻力训练组：BR-Tr (n = 6) 和对照组：BR-Cont (n = 6)。计算膝伸肌、膝屈肌、内收肌、跖屈肌和背屈肌群及其各个肌肉的体积。卧床休息后，BR-Tr 受试者几乎所有测试的肌肉体积都没有显着变化；相比之下，BR-Cont 组的四个肌肉群的体积显着下降（-12% 至 -8%）。这些结果表明，卧床休息期间的阻力训练可以防止大腿肌肉和小腿肌肉的恶化。 (c) 2006 Elsevier Ltd. 保留所有权利。
The present study aimed to investigate the effect of resistance training on the volume of four muscle groups and/or 17 individual muscles of the human lower limb during 20 days of 6 head-down tilt bed rest. Twelve healthy men were divided into two groups: the resistance training group: BR-Tr (n = 6) and the control group: BR-Cont (n = 6). The volumes of the knee extensor, knee flexor, adductor, plantar flexor, and dorsiflexor muscle groups and their individual muscles were calculated. After the bed rest, the BR-Tr subjects showed no significant change in the volume in almost all tested muscles; in contrast, the volumes of the four muscle groups significantly decreased in the BR-Cont group (-12% to -8%). These results suggest that resistance training during bed rest can prevent the deteriorating of thigh muscles and calf muscles. (c) 2006 Elsevier Ltd. All rights reserved.
