Nutrition significantly affects cardiovascular health in athletes by influencing energy levels and recovery times. A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats supports heart health by providing essential nutrients and maintaining healthy cholesterol levels. Omega-3 fatty acids, found in fish and seeds, play a crucial role in reducing inflammation. Hydration is also vital, as it aids in blood circulation and oxygen delivery to muscles. Thus, an athlete’s nutritional choices can directly impact their performance and long-term cardiovascular health.
