This research mainly explores the antioxidant effect of vitamins in high-intensity cross-country running and the effect of physical supplementation. The subjects were all athletes in trail running sports. Before the experiment, the maximum oxygen uptake of each athlete was measured to predict the exercise intensity in the formal exercise test. After resting for 1 hour, go on high-intensity cross-country racing. During 0, 10, 20, and 30 minutes of exercise, supplement vitamins at 2 mL/kg of body weight. Venous blood is collected within 10, 20, and 30 minutes, and urine is collected within 10 and 60 minutes. Within 20 minutes after the end of the cross-country race, supplement the vitamin content at 5mL/kg body weight. The test subjects had a standard meal at noon that day. The second exercise starts 1 hour after the first exercise, and the exercise plan is the same as the first exercise. The test subjects were the same, cross-country running to exhaustion, the time was recorded, and vitamin supplements were added. The subjective fatigue ratio score is recorded every 10 minutes, and the venous blood fluid balance and urine test indicators are also measured. After 60 minutes of exercise, the SOD content in the control group was 144.87±20.12 (U/ml), and the experimental group was 134.85±10.44 (U/ml), which was statistically significant (P>0.05). Research results show that vitamins help neuronal cells to build more ion channels, replenish consumed energy, achieve prolonged exercise time, stimulate the response of target cells, improve the body’s nerve conduction efficiency, and improve the body’s exercise capacity and antioxidant capacity ability.
