Influence of Nutritional Supplementation and Sports Training on the Physical Fitness of Track and Field Athletes

Abstract

This study aims to understand the influence of nutritional supplementation and sports training on the physical fitness of track and field athletes. Twenty track and field athletes from Chongqing Normal University were supplemented with nutrition and trained for eight weeks. Water, sugar, and vitamins were supplemented. They were trained three times a week, two hours each time. One hour was for special track and field training, and one hour was for physical training. Before and after the experiment, the body composition, sports quality, and functional movement screening (FMS) of the athletes were tested. Compared with before the experiment, the muscle weight of the athletes increased, the fat-free weight increased (p < 0.05), the sports quality significantly improved, the endurance increased, the speed increased, the flexibility improved, the total score of FMS also increased significantly (p < 0.05). Nutritional supplementation and sports training can improve athletes’ body composition and sports quality and enhance limb flexibility and stability, which has a positive impact on physical fitness. They can be applied in practical training.
