An Epidemiological Study On The Causes Of Injury And Recovery Time Of Athletes In National Winter Events

Abstract

PURPOSE: This study conducted an epidemiological investigation on the cause and recovery time of sports injuries during the the preparation phase of winter events and revealed the regular occurrence of sports injuries in winter events. METHODS: The main research methods of this study are related to epidemiology, including the record sheets of sports injuries of the 10 national winter sports teams and the record statistics of the daily injuries of the team doctors. RESULTS: According to the different causes of injury, we divide the causes of injury into strain, accident, technical instability, fatigue, learning new techniques, insufficient preparation activities, fields and facilities, interference by others, and equipment failure. The primary cause of injury is a strain (37.91%), including acute onset of chronic injury and the gradual deterioration of chronic injury. The second cause of injury was accidents (25.63%), mainly due to general falls during training. The third reason for the damage is technical instability (17.69%), mainly due to damage caused by learning new technology or technological transformation. The fourth cause of injury is fatigue (10.11%), which is a mainly acute injury under fatigue. Others included learning new moves (4.33%), insufficient preparation activities (2.17%), fields and facilities (1.26%), interference (0.54%), and equipment failure (0.18%). The percentage of injured athletes who resume training within 7 days is 88.86%, and the percentage of recovery training within 30 days is 98.65%. Among them, alpine skiing, freestyle skiing aerials, and freestyle skiing obstacle chasing events accounted for less than 70% of recovery training within 7 days. CONCLUSIONS: The winter event injury mainly comes from the acute onset of chronic injury and the gradual deterioration of chronic injury. As some athletes are transferred from other events to winter events, there are more acute injuries caused by learning or modification techniques. Most of the injuries caused by the event can resume training within a week.
