Key result
Low physical fitness level was not associated with an increased number of health problems compared to the rest of the cohort (mean 3.7 vs 3.6) in youth elite athletes over 26 weeks.
Why the study?
Youth elite athletes often double training loads upon sport academy enrollment, raising concern that the least fit athletes may face excessive load increases resulting in injury and illness.
Does low physical fitness level increase the number and severity of injury and illness in youth elite athletes newly enrolled in specialized sport academy high schools?
Cohort (n=166)
Yes
Does low physical fitness level increase the number and severity of injury and illness in youth elite athletes newly enrolled in specialized sport academy high schools?
Absolute Event Rate: 3.7% vs 3.6%
Low baseline physical fitness was not associated with an increased number or severity of self-reported injuries and illnesses in youth elite athletes during their first 26 weeks at a specialized sport academy.
Low fitness was not associated with more health problems in youth athletes; hypothesis-generating and should not yet alter fitness screening in sport academies.
Youth elite athletes often double their training and competition load after enrollment into specialized sport academy high school programs. The least fit athletes may be exposed to an excessive and too rapid increase in training load, with negative adaptations such as injury and illness as a consequence. In this study, our aim was to determine whether these least fit athletes were at greater risk of injury or illness during their first school year. Participants were 166 youth elite athletes (72% boys) from a variety of team, technical, and endurance sports newly enrolled into specialized sport academy high schools. The Oslo Sports Trauma Research Center Questionnaire on Health Problems was used to self-report injuries and illnesses weekly for 26 weeks. Athletes completed the Ironman Jr physical fitness test battery at baseline, evaluating endurance, strength, agility, and speed properties. We ranked the athletes based on their combined test scores and identified the least fit quartile. The main outcome was the number and severity of health problems, comparing the least fit quartile of athletes to the rest of the cohort. Overall, the least fit quartile of athletes did not report more health problems (mean 3.7, 95% CI 3.0-4.4) compared with the rest of the cohort (3.6, 3.2-3.9). In conclusion, we demonstrated no association between low physical fitness level and number and severity of injury and illness in youth elite athletes after enrollment into a specialized sport academy high school program.

Moseid et al. (2019) conducted a cohort in Injury and illness (n=166). Low physical fitness level (least fit quartile) vs. Rest of the cohort was evaluated on Number and severity of health problems. Low physical fitness level was not associated with an increased number of health problems compared to the rest of the cohort (mean 3.7 vs 3.6) in youth elite athletes over 26 weeks.
