The body responds to hormonal changes during exercise by adjusting various physiological processes to support increased physical demands. Hormones like adrenaline and noradrenaline elevate heart rate and energy availability, enhancing performance. During prolonged exercise, cortisol helps manage stress and recover energy levels. Additionally, the release of endorphins during physical activity contributes to improved mood and reduced perception of pain. These hormonal adaptations help the body optimize performance, recovery, and overall responses to exercise.
