Abstract

Background: Previous studies performed analysis of the agonist/antagonist ratio (AAR) largely in atlhlete population. However, no study has observed the effects of physical activity on the AAR in different movement velocities on the elderly people.

Aim: This study aimed to analyze the AAR of the lower limbs in elderly participants of the Exercise Guidance Service (SOE) and compare them with sedentary eldery, using a group of young adults as a control group.

Method: 86 individuals divided into three groups: young adult (n=25); sedentary (n=30); active (n=31). Collection of the AAR was made through the isokinetic dynamometer at velocities of 60 and 120°/s.

Results: The results indicated a difference in the velocity of 60°/s for the hip and in the velocity of 120°/s for the knee. In addition, there was a difference between the elderly (active and sedentary) and the adults at ankle.

Conclusion: Although the sedentary elderly presented higher mean values compared to active group, there was no significant difference for AAR of the lower between these groups.
