High-intensity intermittent exercise is a key component of basketball performance and induces substantial metabolic and physiological stress. However, the acute relationships between exercise-induced metabolic changes, inflammatory responses, substrate utilization, and fatigue in female basketball players remain insufficiently understood.\n\nIn this prospective interventional study, eligible female basketball players will complete a standardized interval exercise protocol designed to replicate the physiological demands of competitive basketball. Physiological, biochemical, and perceptual measurements will be collected before exercise, immediately after exercise, and during recovery. Primary outcomes include changes in metabolic and inflammatory biomarkers, energy substrate utilization, and fatigue-related responses. Secondary outcomes include selected physiological and performance-related variables associated with recovery from high-intensity interval exercise.\n\nThe findings of this study will improve the understanding of the physiological responses to interval exercise in female basketball players and may contribute to the development of evidence-based training and recovery strategies aimed at optimizing performance and athlete health.",[71,72,73],"Exercise","Fatigue","Sport Physiology",[75,76,77,78,79,80,81,82],"basketball","Yo-Yo test","High-Intensity Interval Exercise","Reaction Time","Energy Metabolism","Free Fatty Acids","Exercise-Induced Fatigue","Female Athletes","NOT_YET_RECRUITING","2026-08-11",{"date":86,"type":87},"2026-08-12","ACTUAL",{"date":89,"type":65},"2026-09-20",{"date":91,"type":65},"2026-12-30",{"name":5,"class":6},1]
