Abstract

Objective: Analyze the muscular function of the knee joint of field soccer athletes of the under-13, under-15 and under-17 categories, and to compare this variable between the categories, as well as the tactical positioning.

Materials and Method: This cross-sectional study included a convenience sample of field soccer athletes, youth soccer club, in the interior of Rio Grande do Sul, Brazil. The muscular strength evaluation was performed through the isokinetic dynamometer (Biodex System Pro 4 ™) at speeds 60 ° / s and 300 ° / s.

Results: Differences were observed in relation to the isokinetic performance between the under-13 and under-15 categories, being higher values in the latter. In the three categories evaluated, high percentages of uni and bilateral asymmetries of knee extensors and flexors were evidenced. Regarding field positioning, we noticed a significant association between unilateral asymmetry (I: Q ratio) and the attack position. In light of our results.

Conclusions: We support the idea of evaluating muscular performance in young soccer players in order to correct possible asymmetries, since they represent a risk of developing an injury.
