Objective: Polycystic ovary syndrome is a diverse endocrine disorder characterized by hyperandrogenism and ovulatory dysfunction. Hyperandrogenism affects body morphology, resulting in excess weight (overweight or obesity). This study aimed to evaluate the efficacy of high-intensity interval training on serum testosterone levels, body fat percentage, and level of physical activity among women with polycystic ovary syndrome.
Methods: Fifty participants were enrolled in the study and randomly allocated into two groups. Group A performed high-intensity interval training on alternate days per week (total of 12 weeks) and group B performed strength training on alternate days per week (total of 12 weeks). Baseline and 12th-week assessments included serum testosterone levels, body fat percentage using the skinfold method, and level of physical activity assessed using the International Physical Activity Questionnaire.
Results: After 12 weeks of intervention, both groups showed significant improvements in all the outcomes. However, group A (high intensity interval training) showed statistically significant results compared to group B (strength training) in lowering serum testosterone levels (P=0.049) and body fat percentage (P=0.001) and increasing physical activity levels (P=0.006).
Conclusion: After 12 weeks of exercise, both exercises benefited the participants; however, high-intensity interval training specifically was found to be a more effective exercise regimen than strength training in reducing serum testosterone levels and body fat percentage and enhancing levels of physical activity in women with polycystic ovary syndrome.
