Good nutrition supports athletic performance by providing the necessary nutrients for energy production, muscle repair, and overall health. Adequate intake of macronutrients—carbohydrates, proteins, and fats—ensures sustained energy levels and optimal recovery post-exercise. Additionally, vitamins and minerals play crucial roles in metabolic processes and the maintenance of bodily functions. A well-balanced diet tailored to the specific needs of an athlete can lead to improved performance, endurance, and resilience against injuries.
