It is purported that supplementation with Cordyceps Sinensis (CordyMax Cs-4) will improve oxidative capacity and endurance performance. The intent of this investigation was to examine the effects of CordyMax Cs-4 supplementation on VO<(2peak,) ventilatory threshold, and endurance performance in endurance-trained cyclists. Twenty-two male cyclists participated in 5 weeks of supplementation with CordyMax Cs-4 tablets (3 g/d). Training intensity was maintained by weekly documentation and reporting…

NO EFFECT OF CORDYCEPS SINENSIS SUPPLEMENTATION ON TESTOSTERONE LEVEL AND MUSCLE STRENGTH IN HEALTHY YOUNG ADULTS FOR RESISTANCE TRAINING
TLDR
It is suggested that CS is relatively safe to be ingested; however, CS supplementation for eight weeks neither appear to possess a significant ergogenic value nor affect testosterone level of resistance-trained young male adults.
Cordyceps militaris Improves Tolerance to High-Intensity Exercise After Acute and Chronic Supplementation
TLDR
Acute supplementation with a Cordyceps militaris containing mushroom blend may improve tolerance to high-intensity exercise; greater benefits may be elicited with consistent chronic supplementation.
Effects of Concurrent Training and a Multi-Ingredient Performance Supplement Containing Rhodiola rosea and Cordyceps sinensis on Body Composition, Performance, and Health in Active Men.
TLDR
Despite MIPS improving certain aspects of weekly training performance, supplementation with MIPS for 14 weeks did not improve body composition, overall training and performance outcomes, or blood biomarkers of health in response to concurrent training in young men compared to PLA.
Effects of Concurrent Training and a Multi-Ingredient Performance Supplement Containing Rhodiola rosea and Cordyceps sinensis on Body Composition, Performance, and Health in Active Men
TLDR
Despite MIPS improving certain aspects of weekly training performance, supplementation with MIPS did not improve body composition, overall training and performance outcomes, or blood biomarkers of health in response to concurrent training in young men compared to PLA.
The Effects of High and Low-Dose Cordyceps Militaris-Containing Mushroom Blend Supplementation After Seven and Twenty-Eight Days
TLDR
It is found that short duration supplementation of higher doses of PeakO 2 may improve performance, but differing effects may occur based upon fitness level.
Effects of Eurycoma Longifolia Jack Supplementation on Recreational Athletes` Endurance Running Capacity and Physiological Responses in the Heat
TLDR
Findings suggested that supplementation of the E. longifolia product at a dosage of 150 mg.day-1 for 7 days has not provided beneficial effects on endurance running capacity and physiological responses of recreational athletes in the heat.
The effect of Ashwagandha ( Withania Somnifera ) on anaerobic performance on elite Indian cyclist
TLDR
There was significant improvement in both males and females in all the parameters of anaerobic capacity of elite cyclist and 8 weeks supplementation of ashwagandha leads to improvement in the anaer aerobic capacity of Elite cyclist.
The effects of sr2w-1 supplementation on high-intensity cycling performance and lactate metabolism
TLDR
Despite the small sample size, 3 weeks of SR2W-1 supplementation does not appear to aid cycling performance, attenuate skeletal muscle fatigue, or modify general physiological responses to exercise.

A fermentation product of Cordyceps sinensis increases whole-body insulin sensitivity in rats.
TLDR
It is concluded that CordyMax Cs-4 may have potential beneficial effects by maintaining whole-body glucose disposal with a less pronounced increase in insulin secretion after a carbohydrate challenge, however, its effects on endurance performance remain questionable.
CordyMax Cs-4 improves steady-state bioenergy status in mouse liver.
TLDR
CdyMax is effective in improving bioenergy status in the murine liver, suggesting a mechanism underlying the known clinical effectiveness of CordyMax in alleviating fatigue and improving physical endurance, especially in elderly subjects.

TLDR
Future research on ergogenic effects of herbs should consider identity and amount of substance or presumed active ingredients administered, dose response, duration of test period, proper experimental controls, measurement of psychological and physiologic parameters (including antioxidant actions), and measurements of performance pertinent to intended uses.

In experimental animals, a water extract of cultivated Cordyceps sinensis exhibited sedative action and antiinflammatory effect, inhibited saliva secretion induced by pilocarpine, prolonged sleeping
Chinese caterpillar fungus and world record runners
TLDR
The incredibly rapid ascendency of the Chinese women's track program has led to speculation that illicit drug use was responsible for their success, especially after reports that former East German sports scientists were hired to help train Chinese athletes.
