RESUMO:

Aging is associated with structural and functional changes in the foot which, in turn, may explain the changes observed in the lower-extremity distal powers. These powers have been obtained by the inverse dynamics approach where the segments, including the feet, are considered rigid bodies. However, the foot undergoes deformation during walking, and adopting it as a rigid body is a methodological limitation that restricts the understanding of the function performed by the foot during walking. Recently, more complete methods have been proposed to quantify the mechanical power of the ankle and foot complex, however, these studies focused only on healthy young population thus preventing to apply the results to older individuals. Another limitation of previous studies, that compare the gait of young and elderly individuals, is the lack of control of walking speed even though this variable is considered a confounding variable in the literature. Hence, this study aimed at comparing the mechanical powers of the ankle and foot through a more complete approach considering both young and elderly adults while walking on the ground at different speeds. To investigate the effect of age and speed on the ankle and foot power output profiles, the kinematic and kinetic data of 39 individuals (23 young and 16 older) were obtained from a previously published data set. The results revealed a significantly effect of speed on the outcome variables. In contrast, the factor age did not have a significant effect on any of the dependent variables in the study and did not contribute significantly, compared to speed alone, to explain the changes in the dependent variable.
