This study tested whether taking ashwagandha (KSM-66) daily for 42 days helps athletes recover from training and improve muscle strength. 56 rugby and water polo players took either 600 mg of ashwagandha or a placebo. Researchers measured stress hormones, muscle soreness, and performance tests like grip strength and jumps.
