ABSTRACT
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 (ageâ¯=â¯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 (pâ¯=â¯0.005) between pre-season (4.97 ± 1.57) and post-season (3.24 ± 0.71), in the mean training volume (pâ¯=â¯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) (pâ¯=â¯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 (ßâ¯=â¯0.348; pâ¯=â¯0.044; R²â¯=â¯0.121) and training volume represents a risk factor for illnesses in the following week (ßâ¯=â¯0.397; pâ¯=â¯0.027; R²â¯=â¯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.Key words
