| Objectives: As one of the emerging winter sports in China,Skeleton has a late development,but the performance improves rapidly,so it is now expected to create excellent results in the Beijing Winter Olympic Games.As a sport event with high risk,Skeleton has a high incidence of sports injury.As a huge resistance in training and competition,sports injury will directly affect the training level and competitive performance of athletes.At present,there are few researches on Skeleton in China.Even more,there is actually no research focus on the injury situation.Therefore,it is necessary to understand the current situation of sports injury among Skeleton athletes in China,analyze the possible causes of sports injury,and make suggestions for the establishment of injury prevention system.Methods: Through questionnaire survey,the sports injury status of 22 male and 11 female athletes in China’s national team of steel frame snowmobile was studied.The questionnaire design was completed by referring to the relevant literature of sports injury investigation,soliciting expert opinions and combining with the needs of this investigation and research.The reliability test of the questionnaire was completed by retest method,and the reliability index was 0.84,indicating good reliability.The validity test was conducted by SPSS22.0 version of statistical software,and its KMO value was 0.870,indicating that it was suitable for factor analysis.Further Bartlett spherical test showed that the difference was statistically significant(χ2=143.69,P=0.000),suggesting that the questionnaire had good validity.A total of 43 questionnaires were sent out and 43 were recovered.43 points were valid,the recovery rate was 100%,and the validity was 100%.Two coaches and Three physiotherapists were interviewed.The interview was conducted in the form of telephone interview,mainly to understand the following contents: technical characteristics,training plans,common injuries of athletes,the relationship between sports injuries and different training contents,and the main rehabilitation methods currently used.By means of literature research,mathematical statistics and logical analysis,the present situation,causes and prevention methods of sports injury for skeleton athletes in China were analyzed.Results: The incidence of collision injury,fatigue injury and strain injury was the highest,and the injury times per capita were 0.45,1.36 and 0.63,respectively.The incidence of fatigue injuries was 48.5%,75.8% and 12.1% in waist,knee and ankle,respectively.The incidence of strain was 27.3% and 12.1%,respectively,in the posterior group of thigh muscle and calf.Shoulder joint injury is a potential special injury.Strength training is easy to cause fatigue injury of waist and knee joint.Sprint training and starting training are easy to cause fatigue injuries of waist,knee and ankle joints and lower limb strain.The technical link of the curve slide is prone to collision.At the same time,athletes and coaches attach less importance to rehabilitation training.Conclusion: bumps,waist and knee,ankle injury and lower extremity injury to Skeleton athletes in our country the main special damage,suggested by strengthening technical training,strength training,strengthen the region associated stability training,pull to relax,and education of the importance of athletes for rehabilitation training to reduce the occurrence of injury. |
