Effect of Cs-4 (Cordyceps sinensis) on Exercise Performance in Healthy Older Subjects: A Double-Blind, Placebo-Controlled Trial
Key Finding
Cordyceps supplementation (1g daily) improved aerobic capacity and exercise performance in older adults over 12 weeks.
Plain-English Summary
This double-blind, placebo-controlled trial investigated Cordyceps sinensis supplementation on exercise performance in 20 healthy older adults (60-75 years). Participants received 333mg of Cordyceps three times daily or placebo for 12 weeks.
The Cordyceps group showed significant improvements in metabolic and ventilatory thresholds, indicating enhanced aerobic capacity. Maximal oxygen consumption (VO2 max) increased, suggesting improved cardiovascular fitness and energy metabolism.
Cordyceps has traditionally been used to combat fatigue and enhance stamina. The mushroom appears to improve cellular energy production by enhancing ATP synthesis and oxygen utilization. While this study focused on physical performance, improved energy metabolism also supports cognitive function, as the brain is highly energy-dependent. Cordyceps was well-tolerated with no adverse effects reported.
