Abstract
Introduction and objectives: women with hyperkyphosis have respiratory disorders and shortness of breath, which is associated with a decrease in oxygen supply and metabolic capacity of peripheral muscles and early fatigue. This research investigates the effect of aerobic and corrective exercises on the aerobic performance of women with postural hyperkyphosis.
Materials and methods: 32 women with a kyphosis angle greater than 40 degrees were purposefully selected and randomly divided into four groups of eight people (control group, aerobic exercise group, corrective exercise group, combined aerobic and corrective exercise group). Aerobic and corrective exercises (including stretching, mobility, and strength) were performed for 6 weeks. Kyphosis angle and aerobic performance were measured before and after the intervention. Aerobic performance was measured through the Bruce test. ANCOVA test was used to evaluate the effect of the pre-test and the effect of exercise on the variables of the exercise group. Correlated t-test was used to compare the average of research variables before and after the exercise protocol. Hypotheses were tested at a significance level of p≤0.05. SPSS version 23 was benefited for data analysis.
Findings: The results showed that aerobic exercises (p=0.020), corrective exercises (p=0.023), and their combination (p=0.002) had a significant effect on aerobic performance. The greatest effect was for combined exercises. Aerobic exercises (p=0.131) had no significant effect on the kyphosis angle. Corrective (p=0.001) and combined exercises (p=0.001) had a significant effect on reducing the kyphosis angle.
Conclusion: Aerobic exercises can restore lung capacities and improve body structure; they have, along with corrective exercises, a double effect on improving the kyphosis angle. Therefore, the aerobic and corrective exercises are effective in improving the kyphosis angle and aerobic performance.
