Introduction: Overtraining in football is caused by an imbalance between body load, stress, and recovery. High-volume non-scientific physical training and continuous high-intensity football matches are often the main reasons for the overtraining of athletes. Objective: This article explores the characteristics of the changes in physical function of football players during a complete training cycle. Methods: We use experimental methods to analyze the changes in the physical load characteristics of football players during high-intensity training. Results: Creatine kinase, urea nitrogen, and oxygen transport indicators did not change significantly during football training. Testosterone and cortisol will gradually increase with an increase of exercise load. Conclusion: In football training, we need to reasonably arrange the total exercise volume, exercise intensity, and exercise interval time of the athletes according to the trainer’s physical adaptability and athletic ability, supplemented with nutrition and enthusiasm recovery measures. These methods can improve or enhance the physical function of football players. Level of evidence II; Therapeutic studies - investigation of treatment results.
Basketball often leads to injury of the flexor tendon. And surgery is an effective way to perform flexor tendon injuries. Collagen biofilm can effectively prevent postoperative tendon adhesion. Because of this, we analyzed the effect of collagen biofilm in preventing postoperative adhesion of flexor tendon injury caused by basketball. This article discusses 80 patients who came to our hospital for treatment and were diagnosed with basketball flexor tendon injuries. We randomly divide them into two groups. In the observation group, 3-0 or 4-0 atraumatic suture modified Kessler’s method, or internal “8” suture was used to repair the flexor tendon with (1–2) × 4 cm biofilm or liquid coating around the suture of the tendon. The control group was treated by suturing the wound after hemostasis. Compare the efficacy of the two and other biological indicators. The study found statistical differences in the postoperative mobility and excellent and good rate of the two groups of patients. For this reason, we believe that collagen biofilm can be effective in the surgical treatment of flexor tendon injuries caused by basketball. This method is worthy of clinical application.
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.
