Centrifugal intensity and duration as countermeasures to soleus muscle atrophyThe effects of artificially induced gravity on the atrophy process of slow-twitch soleus muscle are studied in order to determine whether centrifugation could be an effective countermeasure to nonweight bearing at 1 G. It is observed that the soleus muscle atrophied 32 percent during seven days of nonweight bearing without countermeasures, and centrifugation treatment did not completely prevent atrophy relative to precontrol wet weight of the soleus muscle. Nonweight-bearing groups receiving treatments of 1, 1.5, or 2.6 G had 48, 56, and 65 percent, respectively, of the atrophy observed in a nonweight-bearing-only group compared with the precontrol group. It is concluded that, as a countermeasure to nonweight-bearing-induced atrophy of the soleus muscle, centrifugation at 2.6 G is no more effective than exposure to 1 or 1.5 G.
