Abstract Summary
Objective: This study investigates the effect of Ashwagandha supplementation on physical performance and muscle recovery in active adults.
Context: Ashwagandha is widely known for its adaptogenic properties, including its potential to enhance physical performance by reducing fatigue and promoting muscle recovery. Athletes and physically active individuals have used Ashwagandha to improve strength, endurance, and post-exercise recovery.
Methods Used
Approach: A 12-week, double-blind, placebo-controlled trial was conducted with 100 healthy adults (ages 25-45) who engaged in regular physical activity. Participants were randomized into two groups: one receiving 600 mg of Ashwagandha root extract daily and the other receiving a placebo.
Data Collection: Physical performance was measured by VO2 max, strength (via one-rep max for bench press and leg press), and muscle recovery through the visual analog scale (VAS) for soreness at baseline, 6 weeks, and 12 weeks.
Researchers' Summary of Findings
Impact on Health: By the end of the study, participants in the Ashwagandha group demonstrated a 12% increase in VO2 max, a 10% improvement in bench press strength, and an 8% improvement in leg press strength. Muscle soreness, as measured by the VAS, decreased by 15% in the Ashwagandha group compared to a 4% decrease in the placebo group.
Health Implications: This study supports the efficacy of Ashwagandha supplementation in enhancing physical performance and aiding muscle recovery in active adults. The significant improvements in VO2 max and muscle strength suggest that Ashwagandha may serve as a natural ergogenic aid. However, additional studies are needed to explore its potential applications in athletes and different populations.
