Abstract
- In this study, we compared the knee strength parameters tested in professional football players at the preparatory and competitive seasons, separated by 12 weeks. Knee extensors and flexors peak torque, hamstring to quadriceps conventional ratio (H/Qcon), and bilateral asymmetry index (AI) on the dominant and non-dominant limbs of 10 football players were evaluated in an isokinetic dynamometer. Paired t-test was used to compare all variables between the preparatory and competitive seasons. A one-sample t-test was used to compare the H/Qcon and AI with theoretical means defined as 0.6 and 10%, respectively. The results showed a significant peak torque improvement in the dominant side for both knee extensors (p=0.013) and flexors (p=0.003), whereas on the non-dominant limb there was no significant difference. Regarding the H/Qcon, dominant and non-dominant sides were below 0.6 during the preparatory and competitive seasons (p
