The main reasons for injury are: insufficient training level, poor physical fitness, incorrect movements and lack of self-protection ability; There are no or insufficient warm-up activities before exercise, lack of training to adapt to the environment, and improper teaching and competition organization.
Sports injury is more acute than chronic, and acute injury can be transformed into chronic injury due to improper treatment or premature training.
