Abstract

This study aims to provide insights into nutritional and ergogenic strategies that support athletic performance by examining the physiological changes occurring during and after exercise. Research in the field of exercise physiology highlights the significance of proper nutrient intake and supplementation in enhancing performance. In this context, studies conducted between 2014 and 2024 were reviewed to evaluate the effects of nitrate on exercise performance. During exercise, glycogen stores are primarily used for energy; as these stores are depleted, the creatine phosphate and lactic acid pathways become active. Lactic acid accumulation contributes to muscle fatigue, whereas exercise-induced adaptations lead to an increase in mitochondrial density, making energy production more sustainable. Additionally, oxidative stress levels rise during physical activity, while the body's antioxidant defense mechanisms become more active. Along with supplements such as creatine, caffeine, and L-carnitine, nitrate—known as a precursor of nitric oxide—has been shown to promote vasodilation, enhancing oxygen and nutrient delivery to muscles and thereby improving performance. The findings indicate that nitrate supplementation may increase endurance performance by approximately 3% and can be beneficial when consumed prior to exercise.
