Hormones play a critical role during exercise by regulating various physiological responses, which includes metabolism as well as other functions such as energy production, growth, and recovery. During physical activity, hormones like adrenaline increase heart rate and energy availability, while hormones such as cortisol help manage stress and metabolism. Additionally, growth hormones and testosterone promote muscle growth and repair, enhancing overall performance and recovery.

By influencing how the body utilizes carbohydrates, fats, and proteins, hormones ensure that energy systems are efficient and responsive to the demands of exercise. Their involvement is essential for adapting to the physical stresses placed on the body during workouts, thereby facilitating improvements in strength, endurance, and overall fitness. This multifaceted role underscores the importance of hormonal balance in achieving optimal exercise performance and recovery.
