Muscle Fatigue Assesment of the Lower Limb in Young Hurdlers Using Isokinetic Dynamometry
This research study aim was to assess muscle fatigue of the dominant and non-dominant lower limb (knee flexion/extension, hip abduction/adduction and ankle plantar/dorsoflexion), using Biodex System 4 ProTM. This investigation tested the lower limb muscles during isokinetic concentric/concentric mode at 60o /sec,120o /sec, 300o /sec,450o /sec. Hip abduction/adduction of the right and left side values range for total work from 101.6 J to 528.1 J ; work first third from 32.7 J to 164.7 J; work last third from 25.2 J to 183.7 J. Knee flexion/extension of the right and left side values range for total work from 443.2 J to 792.2 J; work first third from 135.7 J to 258.7 J; work last third from 124.1 J to 249.2 J. The present study suggests that as we change the velocity, muscle fatigue can affect the kinetic lower limb chain.
