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.\n\nExercise-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.\n\nCordyceps 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.\n\nDespite 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.\n\nObjectives\n\nThe primary objective of this study is to evaluate the effects of Cordyceps supplementation timing on exercise-induced physiological responses and aerobic adaptation following acute and chronic exercise training.\n\nSpecific objectives include:\n\n1. To compare the effects of pre-exercise and post-exercise Cordyceps supplementation on inflammatory response, muscle damage, and oxidative stress following acute exercise.\n2. To compare the effects of pre-exercise and post-exercise Cordyceps supplementation on inflammatory response, muscle damage, oxidative stress, and aerobic capacity following chronic exercise training.\n3. To compare physiological responses among pre-exercise supplementation, post-exercise supplementation, and placebo groups.\n4. To evaluate the interaction between supplementation timing and exercise exposure on selected physiological biomarkers.\n5. To investigate the relationship between changes in oxidative stress, muscle damage, and aerobic adaptation.\n\nStudy Rationale\n\nThe scientific rationale of this study is based on the hypothesis that the timing of nutrient delivery may influence physiological responses to exercise. Supplementation administered before exercise may enhance physiological preparedness and reduce exercise-induced stress, whereas supplementation administered after exercise may facilitate recovery and tissue regeneration processes. Identifying the optimal timing strategy may improve recovery efficiency and maximize training adaptation.\n\nStudy Outcomes\n\nThe study will evaluate biomarkers associated with inflammation, oxidative stress, and muscle damage, including IL-6, MDA, and CK. Aerobic adaptation will be assessed through maximal oxygen uptake (VO2max). In addition to biochemical markers and aerobic capacity, neuromuscular performance will be assessed using countermovement jump (CMJ) testing performed on a validated VALD system. CMJ variables will be used to evaluate lower-body power output and neuromuscular recovery status following acute and chronic exercise exposure.\n\nPotential Significance\n\nThis study is expected to generate novel evidence regarding the role of Cordyceps supplementation timing in athletic recovery and adaptation. The findings may support the development of evidence-based nutritional strategies for athletes, coaches, sports scientists, and healthcare professionals. Furthermore, the study may contribute to a better understanding of the relationship between oxidative stress, inflammation, muscle damage, and aerobic adaptation during exercise training.",[42,48,53],{"label":43,"type":44,"description":45,"interventionNames":46},"Pre-Exercise Cordyceps","EXPERIMENTAL","Participants receive Cordyceps supplementation twice prior to exercise sessions, with administration occurring approximately 11 hours and 1 hour before exercise.
