BACKGROUND: Polycystic ovary syndrome (PCOS) is a multifactorial disorder characterized by hyperandrogenism, ovulatory dysfunction, and metabolic disturbances. Physical exercise is known to improve metabolic and hormonal profiles, yet the optimal type and intensity remain unclear.
OBJECTIVE: To compare the effects of high-intensity interval training (HIIT) versus regular-intensity training (RIT) on the free androgen index (FAI) and other hormonal and metabolic parameters in women with PCOS.
METHODS: Forty-eight women with PCOS were randomly assigned to a 12-week supervised exercise program: HIIT (n = 24) or RIT (n = 24). Serum hormone and metabolic parameters were measured at baseline and post-intervention. Age was included as a covariate in analyses due to between-group differences.
CLINICAL TRIAL NUMBER: Not applicable.
RESULTS: After 12 weeks, the HIIT group showed a significantly greater reduction in FAI and HOMA-IR compared with RIT (p < 0.05). Improvements in BMI, LH/FSH ratio, and fasting insulin were also more pronounced in the HIIT group. Bonferroni corrections and effect sizes (Cohen's d) were calculated for all multiple comparisons.
CONCLUSION: HIIT appears to exert superior effects on androgenic and metabolic profiles compared with RIT, suggesting its potential as an efficient, non-pharmacological intervention for PCOS management. The clinical significance of these findings supports incorporating structured HIIT protocols into individualized PCOS treatment strategies.
CLINICAL TRIAL NUMBER: Not applicable.
