Influence of Nicotine on Evaluation Indexes of Volleyball Players' Physical Training

Objectives: This paper studies the effect of nicotine on the recovery of articular cartilage injury and physical training of volleyball players. Methods: In this study, a rat model of cartilage defect was established, and BMSCs sodium alginate gel was used to repair and give nicotine treatment. On the other hand, 20 volleyball players in our school were taken as the experimental objects. Group A is the experimental group and group B is the control group, with 10 people in each group. The experimental group was tested in smoke-free environment for one week. The control group was tested in smoke-free environment for one week. The physical differences between the two before and after the experiment were compared. Results: BMSCs composite alginate gel can repair cartilage defects well, and nicotine has an adverse effect on its defect repair effect. The repair tissue produced by BMSCs composite alginate gel is similar to normal cartilage. Nicholas Ding Ke affects the morphology of chondrocytes and proteoglycan synthesis in matrix. After 10 weeks of physical exercise function training, the total score of functional movement screening (FMS) index of the experimental group in smoke-free environment showed significant difference compared with that before the experiment. It shows that after 10 weeks of physical exercise function training, the injury degree of athletes in the experimental group in smoke-free environment has been significantly improved, and their physical fitness has also been relatively improved. Conclusion: Nicotine has a certain impact on the recovery of bone and joint injuries and physical training of volleyball players. Volleyball players should smoke less or even no smoking in order to improve their performance. Non smoking volleyball players should not be in a passive smoking environment for a long time.
