Abstract Summary
Objective: To assess the impact of KSM-66 Ashwagandha supplementation on muscle strength and recovery in healthy adult males engaged in resistance training.
Context: KSM-66 is a high-concentration, full-spectrum Ashwagandha root extract known for its adaptogenic properties, including potential benefits in enhancing physical performance and energy levels.
Methods Used
Approach: A randomized, double-blind, placebo-controlled trial was conducted over eight weeks.
Data Collection: Fifty-seven male subjects with little experience in resistance training were randomly assigned to receive either 300 mg of KSM-66 Ashwagandha root extract twice daily or a placebo. Muscle strength was measured using one-repetition maximum (1-RM) tests for bench press and leg extension. Muscle recovery was assessed by measuring serum creatine kinase levels, and body composition was analyzed using dual-energy X-ray absorptiometry (DEXA) scans.
Researchers' Summary of Findings
The study found that participants supplementing with KSM-66 Ashwagandha experienced significantly greater increases in muscle strength on the bench press and leg extension exercises compared to the placebo group. Additionally, the Ashwagandha group exhibited a greater reduction in exercise-induced muscle damage as indicated by lower serum creatine kinase levels. These findings suggest that KSM-66 Ashwagandha supplementation may enhance muscle strength and promote recovery, thereby contributing to improved energy levels during physical activity.
