Abstract
PURPOSE: This study aimed to propose an exercise technique that helps improve the skeletal muscle function while suppressing the symptoms of respiratory distress, by mediating squat exercises in whole-body vibration for patients with severe COPD, and comparing the post intervention pulmonary function and activity of quadriceps.
METHODS: Totally, 21 patients with severe COPD were randomly assigned to two groups through clinical sampling: experimental group I included 11 patients (Squat exercise combined with whole-body vibration exercise), and experimental group II included 10 patients (Only squat exercise). Before intervention, we measured pulmonary function using a pulmonary function tester, muscle activity of quadriceps using surface EMG, and gait ability using the 6MWT.
RESULTS: Comparison of intra-group changes in both experimental groups showed a significant increase in the activity of rectus femoris, vastus medialis, and vastus lateralis, and also in the 6MWT. Intra-group comparisons also revealed significant difference in the activity of rectus femoris, vastus medialis, and vastus lateralis (p < .05).
CONCLUSION: Squat exercise combined with wholebody vibration significantly increased the activity of the quadriceps muscle, suggesting that this intervention helps maintain the function of skeletal muscles and prevent muscle atrophy. Therefore, studies to develop protocols using whole body vibration in clinical practice as an exercise method can safely be performed in severe COPD patients, as considered necessary.
