Nutritional supplementation during the training phase has an essential impact on the training effect of athletes. A rational/scientific nutritional supplementation strategy can help athletes better adapt to the demands of training, it can also prevent potential injuries due to insufficient or unbalanced nutrition. At the same time, it helps to develop a rational dietary program so that athletes can recover more quickly after training. This paper will use the literature method to review the nutritional requirements of sprinters in the training phase to provide theoretical references for improving sprinters' competitive level. The results of the study are as follows: (1) Sprinting requires different types of energy supply according to different events. (2) Sprinting mainly focuses on speed and power; therefore, nutritional supplementation for sprinters needs to focus on nutrients related to lean body mass, strength, and explosive power (3) Protein‐rich foods help enhance explosive and strength performance during exercise. And, to reduce body fat levels, avoid high‐fat foods, and prioritize nutrient‐dense foods. (4) Sprinters can optimize glycogen reserves in the muscles and liver by consuming cereals and root foods or cow's milk powder for glycogen supplementation. And, in consuming protein‐based meals, it is essential to consume high‐quality proteins. Also, during the training phase, the use of creatine supplements can enhance certain sprints and high‐intensity training and increase the content and re‐synthesis rate of creatine phosphate. Finally, attention needs to be paid to the intake of carbohydrates and trace elements such as selenium, zinc, and copper as a means of enhancing antioxidant power, eliminating peroxides, and guaranteeing the viability of red blood cells. Through the organization and study of the literature, it can be found that the intake of a certain kind of food cannot meet the nutritional needs of sprinting in the training stage, so we can use compound nutritional regulations to ensure the intake of a variety of nutrients. In addition, although the majority of athletes have the positive will and mentality to develop rational dietary behaviors, they may not be able to guide their own nutritional intake correctly, so correct nutritional knowledge can be integrated into athletes' daily training and life by means of lectures, brochures, and posters in order to strengthen the level of nutritional knowledge of athletes.
