![عکس صفحه اول مقاله: Effect of unloading on muscle volume with and without resistance training Effect of unloading on muscle volume with and without resistance training](/preview/png/1717116.png)
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∘6∘ head-down tilt bed rest. Twelve healthy men were divided into two groups: the resistance training group: BR-Tr (n=6)(n=6) and the control group: BR-Cont (n=6)(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 (-12-12% to -8-8%). These results suggest that resistance training during bed rest can prevent the deteriorating of thigh muscles and calf muscles.
