ABSTRACT
Objective:
To evaluate the muscular fatigue of flexors and knee extensors in active and sedentary individuals.
Methodology:
The International Physical Activity Questionnaire (IPAQ), Physical Activity Alert Questionnaire (PAR-Q) and functional clinical examination were performed in order to guarantee safety during Isokinetic Dynamometry, performed in 3 sets of 5 repetitions of the knee flexion and extension movements, at speeds 120º/s, 180º/s and 240º/s.
Results:
Sedentary individuals had a higher fatigue index, being this difference significant in the left hamstrings.
Conclusion:
It is important to determine the fatigue index, since the fatigue of the muscles directly interferes with the muscular performance and the appearance of injuries.
