Effect Increase
Trial Design Double blind
Trial Length 1-6 months
Number of Subjects 40
Gender Both Genders
Age Range 18-29
Body Types Average
Notes for this study:
Supplementation of 500mg of the water extract of ashawanghda has been noted to improve power output and velocity of sprints, as well as to improve VO2 max without affecting blood pressure.

Effects Of Eight-week Supplementation Of Ashwagandha On Cardiorespiratory Endurance In Elite Indian Cyclists

Effect Increase
Trial Design Randomized trial
Trial Length 1-6 months
Number of Subjects 45
Gender Male
Age Range 18-29, 30-44
Body Types Average
Notes for this study:
Eight weeks supplementation of 500mg of the water extract of ashwagandha roots to elite cyclists was able to increase their VO2 max on a treadmill test (12.5%) and time to exhaustion (7.2%) with no significant influence on RER.

Efficacy Of Ashwagandha (Withania Somnifera [L.] Dunal) In Improving Cardiorespiratory Endurance In Healthy Athletic Adults

Effect Increase
Values 20-m shuttle run. Placebo: before 42.18 (5.3), after 44.04 (5.95). Ashwagandha: before 41.74 (5.21), after 47.41 (6.63).
Trial Design Randomized trial
Trial Length 1-6 months
Number of Subjects 50
Gender Both Genders
Age Range 18-29, 30-44
Body Types Average
Notes for this study:
In a randomized, double-blind, placebo-controlled trial, 50 healthy, young, active participants were allocated equally to take either 600 mg of ashwagandha (standardized 5% withanolides) or placebo daily for 12 weeks.

Compared with the placebo group, the ashwagandha group saw a statistically significant increase in VO2max as evaluated by 20-m shuttle test after 12 weeks. There were also statistically significant improvements in quality of life as measured by WHO-QOL for physical health, psychological health, social relationships, environmental factors.
