Ashwagandha has long been used to remedy general weakness, while boosting vitality and stamina. This infographic details clinical research assessing whether ashwagandha had a measurable impact on enhancing cardiorespiratory endurance, helping to improve quality of life in healthy athletic adults.
Ashwagandha is a known adaptogen, valued for its ability to increase vitality, energy, endurance and stamina, suggesting it could enhance physical performance. The question is whether a high concentration root extract of ashwagandha could enhance
cardiorespiratory endurance and improve quality of life (QOL) in healthy athletic adults
A prospective, double-blind, randomized, placebo-controlled trial at Hyderabad Spine Clinics, Secunderabad, India. A total of 50 healthy adults aged between 20 and 45 years and normal body mass index (BMI) received 300 mg twice daily of ashwagandha (as KSM-66) or placebo for 12 weeks. Efficacy was evaluated by conducting
a 20-minute Shuttle Run Test at baseline, week 8 and week 12, with a look at oxygen consumption
at peak physical exertion (VO2max); and quality of life assessed by a self-reported World Health Organization-QOL questionnaire
Over the course of the study and at conclusion, in adults taking ashwagandha:
“High-concentration full-spectrum Ashwagandha root extract improves an individual’s resistance toward stress and thereby improves self-assessed quality of life.”
As adults look to get more yield from their workouts, improving VO2max—or the amount of oxygen the body can use during exercise— supports muscle efficiency and performance.1 Further, quality of life measures are critical to ensuring exercise enhances both physical and psychological measures.2 Ayurvedic formulas known as Rasayana— such as ashwagandha—have been used as a remedy for general weakness and to improve vitality and stamina; however, research
was needed to prove clinical efficacy. The study results suggest ashwagandha (as KSM-66) enhances both cardiorespiratory endurance and quality of life in healthy, athletic adults.
