To investigate the effects of resistance exercise and fish oil intake on muscle morphology in Wistar rats.METHODS:
Forty-eight animals that performed resistance exercise were initially divided into two groups. One group did not take fish oil and the other group took fish oil. The animals of the second group underwent training and took fish oil for eight weeks. At the end of the last resistance exercise session, the 48 rats were organized into six subgroups of eight each, according to the time gap (12, 24 or 48 hours) elapsed until the gastrocnemius muscle withdrawal procedure. At each established time after the last resistance exercise session, the gastrocnemius muscle was removed for morphological analysis.RESULTS:
Skeletal muscle cells of the animals that did not receive fish oil presented higher scores of edema, especially those from the groups that had their muscles withdrawn at 24 and 48 hours of time gap. As for the group that took fish oil, we observed a smaller amount of inflammatory infiltrate and reduced areas of necrosis compared to animals that exercised without the use of fish oil, at all post-exercise time gaps.CONCLUSIONS:
Fish oil intake attenuated morphological changes in muscle tissue after high-intensity exercises
