Abstract
Introduction: The physical performance of runners is dependent on biomechanical factors. In addition to aerobic capacities, body composition significantly affects fitness status. Arginine is a precursor to nitric oxide gas. Blood flow to the involved organs during exercise. It is proposed to provide more substrates for enhancing athletic performance. Exercise stimulates metabolic processes, and increases the release of nitric oxide. Athletes engage in specific exercises and consume dietary supplements to optimize athletic performance. The purpose was to determine the impact of eight weeks of aerobic activities with and without arginine supplementation on body mass index, body fat percentage, and aerobic capacity on female endurance runners.
Methodology: Among female endurance runners aged 20 to 30 in the Mashhad, 32 participants were purposefully selected through random sampling and divided into four equal groups: aerobic exercise with arginine, arginine, aerobic exercise and Placebo. Before conducting the pre-test, the participants were homogenized based on the entry criteria in the study. Dietary intake and menstrual habits of the participants were controlled. Training engaged in aerobic exercises for eight weeks, three times per week, with an intensity of 60 to 70 percent of maximum heart rate. 80 mg of arginine per kilogram of body weight per day after breakfast was consumed for eight weeks, Placebo took the same form and taste as arginine supplement. Body mass index, body fat percentage and aerobic capacity were measured before and after the exercise and supplement intervention. Data analysis was conducted at a significant level of 5%. One-way analysis of variance, and Tukey's post hoc test were utilized in the statistical analysis.
Results: The eight weeks of aerobic exercise, both with and without arginine supplementation, led to a significant reduction in post-test body fat percentage(P=0.016), body mass index (P=0.007) and significant increase in aerobic capacity(P=0.005) for female endurance runners.
Conclusion: In order to improve certain performance factors in sports, such as aerobic capacity, body fat percentage, and body mass index, it is necessary to incorporate aerobic exercises and nutritional strategies, especially the intake of arginine, into endurance athletes' dietary plans. This may lead to improved athletic performance.
