The main aim of this study was to examine the effect of L-arginine supplements on individuals' athletic abilities and physical condition. The study involved 18 male track and field athletes between the ages of 15 and 37 years who were affiliated with sports clubs in FC Sherwana, Kurdistan-Iraq. Participants were randomly divided into two groups: one received L-arginine supplements and the other received placebos. Over 30 days, the athletes were given either a daily dose of 4 g of L-arginine or an equivalent amount of placebo. Pre- and post-intervention assessments were conducted to evaluate exercise performance, body mass index (BMI), body fat mass (BFM), and lean body mass (LBM). The mean age of the participants was 23.14 ± 2.75 years. The group that received L-arginine supplementation showed a significant improvement in exercise performance (4.15 ± 0.35) compared to the placebo group (2.89 ± 0.76) (P = 0.04) . This increase in performance remained significant throughout the study even after accounting for baseline values, physical activity, and usual dietary intake. Furthermore, L-arginine supplementation had a significant impact on weight, BMI, BFM and LBM with values ​​of (68.31 ± 10.11), (22.30 ± 1.12), (14.07 ± 6, 99) or (54.67 ± 4.75). The p values ​​for these effects were (0.09), (0.02), (0.05), and (0.02), respectively. Overall, the results suggest that a daily intake of 4 g of L-arginine may increase the athletic performance of male track and field athletes and also impact various anthropometric measurements such as BMI, BFM and LBM.
