Evaluación isocinética de músculos flexores y extensores en jugadores de fútbol profesional antes de iniciar la fase de pretemporada

Objective

Assessment the concentric isokinetic performance of the flexor and extensor muscles of the joints of the knees legs dominant and not dominant prior to the commencement of a new soccer season.

Material and methods

A total of 30 high-performance professional soccer players aged between 18 and 33 years, and 86% had the right leg as dominant (kick) and the remaining 14% left leg. All underwent isokinetic testing in angular velocity of 60°/s in the dynamometer using concentric muscle action.

Results

The following results were obtained: peak torque in angular velocity of 60°/s of the flexors of the dominant leg (DL) was higher than 3% to the non-dominant leg (NDL), but this difference was not significant. Unlike the torque pique the extensor muscles of the NDL was 9% higher (P = 0.06) than DL. The percentage of flexors/extensors ratio for peak torque NDL was abnormal and below 7% (P = 0.09) than DL.

Conclusion

These results indicate the need for prior assessment of the flexor and extensor muscles of the knee as a preventive conduct before starting the training program of high performance soccer players.
