摘　　要：Purpose:The study aimed to investigate the role of training load characteristics and injury and illness risk in youth ski racing.Methods:The training load characteristics as well as traumatic injuries,overuse injuries,and illnesses of 91 elite youth ski racers(age=12.1±1.3 years,mean±SD)were prospectively recorded over a period of 1 season by using a sport-specific online database.Multiple linear regression analyses were performed to monitor the influence of training load on injuries and illnesses.Differences in mean training load characteristics between preseason,in-season,and post-season were calculated using multivariate analyses of variance.Results:Differences were discovered in the number of weekly training sessions(p=0.005)between pre-season(4.97±1.57)and post-season(3.24±0.71),in the mean training volume(p=0.022)between in-season(865.8±197.8 min)and post-season(497.0±225.5 min)and in the mean weekly training intensity(Index)(p=0.012)between in-season(11.7±1.8)and post-season(8.9±1.7).A total of 185 medical problems were reported(41 traumatic injuries,12 overuse injuries,and 132 illnesses).The weekly training volume and training intensity was not a significant risk factor for injuries(p>0.05).Training intensity was found to be a significant risk factor for illnesses in the same week(β=0.348;p=0.044;R^(2)=0.121)and training volume represents a risk factor for illnesses in the following week(β=0.397;p=0.027;R^(2)=0.157).Conclusion:A higher training intensity and volume were associated with increased illnesses,but not with a higher risk of injury.Monitoring training and ensuring appropriate progression of training load between weeks may decrease incidents of illness in-season.
