Introduction: Elderly is a process that involves slow and progressive changes with the aging of human body. These natural changes will be affected by factors such as gender, race, social status, and even occupation. As a result, aging leads to a reduction in the physical function of daily living. Hence, falling and in-activity are one of the most common problems in the elderly, to the extent that it is known to be the sixth cause of death. The main risk factors for falling into elderly people are related to functional limitations; fall in history, increased age, muscle weakness, the use of psychosocial drugs and environmental risks. Thus, the purpose of this study was to evaluate the effect of walking speed on walking kinematic variables among adults.
Methodology: The participants included 15 adult women who participated in the study according to inclusion and exclusion criteria. They were asked to walk along the path of 8 meters in three walking speeds (low, high, and preferred speeds) with bare foot. Before the test, 11 markers were attached to the subject's body, then kinematic variables of walking were recorded by the motion analysis system. To analyze of data, the within group ANOVA test was used.
Results: Results showed that there were significant in three walking speeds. Thus, there is a significant difference between low and high speed, low and preferred speed (P<0.05), but there is no significant difference between high and preferred speed (P>0.05).
Discussion: Based on the results of present research, kinematic variables were affected by speed walking and these results can be used to design exercises and research studies.
