Hydration is crucial for athletes before competition as it significantly affects performance and recovery. Adequate fluid intake helps maintain blood volume, which is essential for effective oxygen transport and thermoregulation during intense physical activities. Hydration also prevents dehydration, which can lead to fatigue, cramps, and impaired concentration. Athletes are advised to drink fluids rich in electrolytes to replenish minerals lost through sweat. A well-hydrated body allows athletes to train harder, achieve peak performance, and recover more effectively after competitions.
