Abstract
Aim: To determine how do performance parameters of the trunk and knee flexors and extensors vary with age.
Subjects and method: 215 subjects (82 men and 133 women), were divided into three age groups: 20 (mean 22.69, SD=1.72, min=20.0; max=28.0), 40(mean 44.81, SD=2.58, min=40.0; max=49.0) and 70-yearold (mean 70.23, SD=2.54, min=65.0; max=74.0).
Results: The values of the peak torque was incrementally reduced with age, more so in men and with respect to the extensors of the trunk.
Conclusion: The results point out to a selective reduction in trunk muscles function. Given the functional significance of these muscles, prevention programs targeting the elderly should take special attention of this finding.
