Análise cinemática da marcha pós protocolo de fadiga global de curta duração

Abstract

AIMS: Evaluate the effects of a short-term fatigue protocol on gait’s kinematic parameters of healthy subjects.METHODS: 21 healthy young adults participated in the sample. The parameters of linear kinematics of gait (velocity, cadence, step length, step width, step time) and angular kinematics of gait (hip’s flexion and extension; knee’s flexion and extension; ankle’s dorsiflexion and plantar flexion) were analyzed before and after performing a short-term fatigue protocol. For gait evaluation, a three dimensional gait trajectory capture system was used, consisting of a kinematic system with 7 integrated cameras. The Short-Term Functional Agility Fatigue Protocol, which consists of a short-term global fatigue protocol with series of functional agility exercises, was used to fatigue participants. For comparisons between pre and post fatigue evaluations, the mean values to paired t test, and statistical significance was set as p < 0.05.RESULTS: There were no statistically significant differences in the angular and linear parameters evaluated, except for cadence (p = 0.03).CONCLUSIONS: The short-term global fatigue protocol did not alter the angular and kinematic gait parameters in young subjects, except for the cadence, that was higher after the fatigue protocol.
