| Outline of Final Research Achievements |
This study performed 30% and 70% of the one repetition maximum squat in rat disuse atrophy model by tail suspension to evaluate the influence of ten days of exercise intervention in the recovery process from disuse atrophy. Although exercise interventions delayed the recovery of lower leg muscles from disuse atrophy, in 30% of one repetition maximum group, quadriceps femoris muscle showed increased mass. The results suggest that intense exercises to disuse atrophied muscles delays the recovery of weaker muscles more affected by disuse, however they could contribute the strengthening of the muscles less affected by disuse atrophy in compensation.
