FUNCTIONAL TESTS AND ISOKINETIC KNEE ASSESSMENT IN STREET RUNNER ATHLETES CORRELATION

CORRELACIÓN ENTRE PRUEBAS FUNCIONALES Y EVALUACIÓN ISOKINÉTICA DE RODILLA EN PRACTICANTES DE CARRERA DE CALLE

ABSTRACT

Introduction:

The assessment of biomechanical changes related to the lower limbs is necessary in clinical practice to measure the potential risks of injury and the influences on existing dysfunction. Biomechanical changes related to previous ankle injuries are known to influence the performance of the entire lower limb.

Objective:

The aim of this study was to correlate muscle strength tests, performance tests and ankle stability with the Single Hop Test (SHT).

Methods:

82 amateur runners were evaluated with isokinetic tests of quadriceps and hamstring muscle strength, as well as Y Balance Test (YBT), Weight-bearing Lung Test (WBLT), and the SHT.

Results:

The results showed there was a significant correlation between the SHT and the YBT in subjects with hamstring/quadriceps ratio (I/Q ratio) <0.55, and the length of the unilateral SHT with the peak torque of ipsilateral knee extensors.

Conclusion:

The study was successful in correlating the functional tests in question with the results obtained in isokinetic dynamometry. Level of Evidence V; Cross-Sectional Study.
