Abstract	This study investigated the effect of curd (Indian dahi) supplementation on sports performance, specifically maximal oxygen uptake (VO₂ max), in resident female athletes aged 18–25 years at the Sports Development Authority of Tamil Nadu. Thirty aerobic athletes received 100 ml of curd daily for 45 days while following a standardized diet and training routine. VO₂ max was assessed using the Harvard Step Test at baseline, 15, 30, and 45 days. The results showed a progressive improvement in VO₂ max, with a notable increase after 30 and 45 days of supplementation. The findings suggest that regular curd intake, as a natural probiotic food, may enhance aerobic capacity and endurance in female athletes, highlighting its potential role as a simple and cost-effective nutritional intervention for improving sports performance.
