Key result
A rapid increase in training load (A:C4) was significantly associated with an increased risk of non-contact injuries (OR 4.39) in young male soccer players.
Why the study?
There is a lack of knowledge regarding the effect of high training load on young athletes, in whom maturity status could alter physiological responses to training.
Cohort (n=23)
No
Odds Ratio: 4.39 (95% CI 2.84–6.79)
p-value: p=<0.01
In young soccer players, a rapid increase in training load combined with decreased recovery status is associated with higher susceptibility to non-contact injuries, with physiological responses varying by maturity status.
No takes yet. Share an insight, caveat, or question.
May warrant cautious load monitoring in youth soccer; hypothesis-generating for causality and maturity-specific thresholds.
Mandorino et al. (2021) conducted a cohort in Healthy young soccer players (n=23). Acute to chronic workload ratio for 4 weeks (A:C4) vs. Lower workload ratio (healthy reference weeks) was evaluated on Risk of non-contact injuries associated with A:C4 (OR 4.39, 95% CI 2.84-6.79, p=<0.01). A rapid increase in training load (A:C4) was significantly associated with an increased risk of non-contact injuries (OR 4.39) in young male soccer players.
