Improving Training Condition Assessment in Endurance Cyclists: Effects of Ganoderma lucidum and Ophiocordyceps sinensis Dietary Supplementation

Summary

This research examined how two medicinal mushrooms – Reishi and Cordyceps – can help protect athletes from overtraining and improve their recovery. The study found that taking these supplements for 3 months helped balance stress hormones and boost antioxidant defenses in cyclists. Unlike traditional antioxidant supplements that may interfere with training adaptations, these mushrooms appear to work through multiple beneficial pathways. Impacts on everyday life: – Provides a natural alternative for athletes and active individuals to prevent overtraining – Offers potential benefits for managing physical and mental stress – Demonstrates how traditional medicinal mushrooms can be integrated into modern sports nutrition – Shows promise for improving exercise recovery and preventing burnout – May help weekend warriors and recreational athletes train more effectively

Background

Fatigue and underperformance affect over 65% of athletes at their career peak. These symptoms are defined as nonfunctional overreaching (NFO) and overtraining syndrome (OTS). NFO requires 72 hours recovery while OTS requires days/weeks. Athletes increase training to improve performance but without adequate rest this can lead to maladapted responses and decreased performance. The mechanisms involve hormonal changes and oxidative stress.

Objective

To evaluate the effects of fungal supplements Ganoderma lucidum and Ophiocordyceps sinensis on athletic performance of road cyclists by monitoring testosterone/cortisol ratios and oxidative stress markers before and after physical exertion.

Results

After 3 months of fungal supplementation, the testosterone/cortisol ratio changed significantly, protecting athletes from NFO and OTS. The data showed increased scavenger capacity of free radicals in athletes’ serum after races. Four out of five athletes who were at risk of overtraining in the placebo condition overcame these symptoms after fungal supplementation.

Conclusion

A 3-month period of O. sinensis and G. lucidum dietary supplementation may protect endurance athletes from nonfunctional overreaching/overtraining by improving hormonal ratios and antioxidant capacity. The supplements provide a viable alternative to traditional antioxidant supplements that may interfere with beneficial exercise adaptations.
