Effects of static interventions on disuse atrophy of the rat soleus muscle at different sites along its longitudinal axis

摘要: [Purpose] The purpose of our study was to verify the inhibitory effects static intervention (heat load and muscle stretching) on disuse-related adaptation changes in soleus compare these across different sites along its longitudinal axis. [Subjects] Forty 8-week-old male Wistar rats. [Methods] heat and/or stretching rat during hindlimb suspension were evaluated by measuring cross-sectional area fibers, succinate dehydrogenase activity, number capillaries proximal, middle, distal regions. [Results] With no proximal region showed highest reduction area, whereas activity due suspension. These differences between regions decreased with both interventions, most pronounced a combination stretching. [Conclusion] Differences structure increased suspension, this heterogeneity associated disuse inhibited including Furthermore, reduced heterogeneity.
