简要总结
Athletes frequently perform high-intensity exercise to improve physical performance and aerobic capacity. However, such training can induce exercise-induced muscle damage, oxidative stress, and inflammatory responses that may delay recovery and compromise subsequent training adaptations. Optimizing recovery strategies is therefore essential to maintain performance, reduce injury risk, and support long-term athletic development.
Cordyceps is a medicinal mushroom that contains several bioactive compounds, including cordycepin and polysaccharides, which have demonstrated antioxidant, anti-inflammatory, and immunomodulatory properties. Although previous studies have reported beneficial effects of Cordyceps supplementation on exercise performance and physiological function, limited evidence exists regarding the optimal timing of supplementation relative to exercise.
This study aims to investigate the effects of different Cordyceps supplementation timing strategies on physiological responses and aerobic adaptation following acute and chronic exercise training. Participants will be assigned to receive Cordyceps supplementation before exercise, after exercise, or placebo. The study will evaluate biomarkers of inflammation (IL-6), oxidative stress (MDA), muscle damage (CK), aerobic capacity (VO2max), and neuromuscular performance assessed using countermovement jump (CMJ) testing.
The findings of this study are expected to provide evidence-based recommendations regarding nutritional recovery strategies and supplementation timing to optimize recovery and training adaptation in athletes and physically active individuals.
详细描述
Background
Recovery is a fundamental component of the training process because physiological adaptation occurs not only during exercise but also during the recovery period following exercise-induced stress. High-intensity exercise is widely used to improve athletic performance and aerobic capacity; however, it is also associated with increased physiological stress, including exercise-induced muscle damage (EIMD), oxidative stress, and inflammatory responses. Excessive accumulation of these responses may impair recovery, reduce training quality, increase injury risk, and contribute to non-functional overreaching or overtraining.
Exercise-induced physiological stress is commonly characterized by elevations in inflammatory biomarkers such as interleukin-6 (IL-6), muscle damage markers such as creatine kinase (CK), and oxidative stress markers such as malondialdehyde (MDA). Conversely, appropriate recovery interventions may facilitate restoration of physiological homeostasis and support positive training adaptations, including improvements in aerobic capacity.
Cordyceps is a medicinal fungus that contains several biologically active compounds, including cordycepin, polysaccharides, nucleosides, sterols, and phenolic compounds. Experimental and clinical studies have demonstrated antioxidant, anti-inflammatory, and immunomodulatory properties of Cordyceps. These mechanisms suggest that Cordyceps supplementation may help attenuate exercise-induced physiological stress while supporting recovery and adaptation processes.
Despite increasing interest in Cordyceps supplementation among athletes, evidence regarding the influence of supplementation timing remains limited. Most previous studies have focused primarily on supplementation efficacy without specifically evaluating whether administration before exercise or after exercise produces differential physiological effects. Understanding the role of supplementation timing may contribute to the development of more effective recovery strategies in sports science.

研究组 & 干预措施
Pre-Exercise Cordyceps
Participants receive Cordyceps supplementation twice prior to exercise sessions, with administration occurring approximately 11 hours and 1 hour before exercise. This intervention is designed to evaluate the effects of pre-exercise supplementation timing on inflammatory response, oxidative stress, muscle damage, neuromuscular performance, and aerobic adaptation following acute and chronic exercise training.
干预措施: Pre-Exercise Cordyceps militaris (Dietary Supplement)
Post-Exercise Cordyceps
Participants receive Cordyceps supplementation immediately after completion of each exercise session. This intervention is designed to evaluate the effects of post-exercise supplementation timing on physiological recovery, neuromuscular performance, and aerobic adaptation following acute and chronic exercise training.
干预措施: Post-Exercise Cordyceps militaris (Dietary Supplement)
Placebo
Participants receive placebo capsules matched in appearance and administration schedule to the Cordyceps supplementation groups. The placebo group serves as the control condition for comparison of physiological and performance outcomes.
干预措施: Placebo (Other)
