Profil isocinétique des muscles fléchisseurs et extenseurs du genou dans une population d’athlètes sauteurs

Introduction. - This study explored concentric and eccentric profile of knee musculature in a jumpers population. Relationships between isokinetic assessment and field tests performances have also been explored. Materials. - Jumpers population presented higher knee flexors performances in concentric and eccentric mode and superior knee extensors strength in eccentric. Significant correlations between isokinetics and field tests results were exclusively observed with athletes quadriceps performances. A very high correlation (r = 0.93) was found between the second bound relative performance of the ten multijumps test and eccentric quadriceps relative peak torque. Conclusion. - Jumpers training may favour a specific muscular development. The knee extensors eccentric strength may be a major factor in the athletic performance. (c) 2005 Elsevier SAS.
