To analyze the causes of muscle soreness and injury during precompetition training in university sports meet and taking the DOMS mechanism as the main line to find a reasonable way to deal with the muscle pain and prevent the injury, 125 college students participating in stadium games training were randomly selected. The muscle pain and injury during the training were obtained through interviews, mathematical statistics, and literature review. The information of exercise load, pain and injury type, exercise ability, pain degree, and recovery time was comprehensively analyzed to study the mechanism of pain and injury formation. Muscle pain and injury occurred in precompetition training, especially in freshmen. After heavy load, muscle soreness occurred, causing DOMS and developing into muscle injury. Affected by the external climate environment, sudden muscle soreness and injury are a gradual transformation process with DOMS as the boundary, which is the comprehensive result of exercise load, water, energy, and material metabolism; control load intensity, water supplement, and energy and material supplement can effectively prevent the occurrence of DOMS, and timely recovery after DOMS symptoms can effectively avoid the occurrence of sports injury. According to the different intensity of exercise, it is of great significance to clarify the mechanism of DOMS and explore effective prevention methods for physical education and sports training.
Objective: Taking DOMS mechanism as the center, tries to find the countermeasures to deal with the muscle pain and prevent the injury in the pre competition training of college games. Methods: 125 students from Guangxi University of science and technology were randomly selected to participate in the training. The data of muscle pain and injury during the training were statistically analyzed. The mechanism of pain and injury was studied from lactate mechanism, glycolysis system, DOMS threshold and other aspects. Results: Muscle pain and injury mainly occur in pre competition training, especially in freshmen. Lack of rest after heavy load is easy to cause muscle pain, DOMS and muscle injury. Conclusion: Pain, DOMS, injury is a gradual process of comprehensive effects of exercise load, energy, material metabolism, etc; controlling load intensity, supplementing water, energy, material, can effectively prevent DOMS, and timely recovery after DOMS can effectively avoid sports injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
