Abstract
High-intensity training and competition consume a lot of physical energy for tennis players. It is not enough to rely on exercise means, physics means and sleep for recovery. The substances consumed during exercise are mainly supplemented by the intake of nutrients in the diet. Although energy intake basically meets the demand, there are situations where carbohydrate intake is too low and protein intake is too high. In the intake of minerals and vitamins, half of athletes do not meet the recommended intake standards. Therefore, this article uses minerals and vitamins as the starting point to explore their impact on sports tennis athletes’ athletic ability, and conduct simulation experiments on our city’s tennis athletes. The experimental results show that only 54.3% of players know the correct three-meal ratio. The high concentration of vitamin C reduces the lipid peroxidation damage of the skeletal muscle cell membrane, thereby reducing the degree of muscle soreness and speeding up recovery. High-intensity training can increase the excretion of Ca in urine and decrease of Ca in blood below the clinical standard. Supplementing Mg additives can effectively enhance athletes' skeletal muscle and cardiac muscle function. Sports tennis players can enhance immune function and relieve fatigue and muscle aches by supplementing vitamin C.
