“…Injury severity is commonly calculated as the number of days elapsed from the day of injury until the day the player returns to full training and/or is available for match selection ( 64 ), often presented as the proportion of injuries falling within defined bins (e.g., percentage of all injuries lasting 7–28 days). Although cut-offs vary slightly between studies and the choice of injury definition affects distributions, the combined findings suggest that 38% (7–74%) of injuries in boys last less than a week, another 38% (16–67%) last between a week and a month, while every fifth injury (21%, 2–37%) lasts more than a month ( 18 , 20 , 21 , 23 , 25 , 28 , 29 , 31 – 37 , 39 , 41 , 46 , 48 , 49 , 53 – 56 , 61 ). For girls, a larger proportion of “mild” injuries is observed, with around a half (51%, 38–52%) lasting a week or less, a third (36%, 32–41%) between a week and a month, and the remaining 16% (12–20%) more than a month ( 55 , 58 , 60 ).…”
