This article analyzes the physiological, biochemical, and psychological bases of athlete fatigue and recovery mechanisms. The processes of energy resource depletion, metabolite accumulation, slowing of neuromuscular transmission, and hormonal changes under high-intensity physical loads are scientifically substantiated. Differences between central and peripheral fatigue and their impact on athletic performance are highlighted. The biochemical (glycogen resynthesis, protein synthesis), hormonal, nervous system, and psychological mechanisms of recovery are thoroughly described. Methods to accelerate recovery, including active and passive rest, proper nutrition, hydration, rehabilitation tools, and psychological techniques, are recommended. The study results are important for scientific planning of training sessions, prevention of overtraining, and achieving high sports performance.
