Correlation of physical activity with step-length and step-width in healthy young adults

Abstract

Background: Gait is one of the most complex neuromuscular phenomena which require perfect coordination between the brain, spine, and muscles. Due to the adverse effects of physical inactivity, physical activity is now considered as the biggest health issue of 21st century. Physical activity effects the gait parameters to variable extent, thus affecting the quality of life. International analyses showed a clear reduction in youth physical activity.

Objectives: The purpose of our study was to identify the gait impairments present in the younger adults and modify their activity levels to avoid impairments and disability in later years of age. The objective was to determine the correlation between physical activity and step-length in healthy adults.

Methods: Gait parameters were assessed in 40 individuals including both males and females. Subjects with any musculoskeletal conditions, neurological impairments and individuals those were unable to follow verbal commands were excluded. Outcomes measure included International Physical Activity Questionnaire (IPAQ) to access physical activity level and observational method to access gait parameters step length and step-width. The data was analyzed using SPSS 21 software.

Results: Physical activity measured through the IPAQ and step-length through observational method showed no significant correlation of physical activity with step-length (p>0.05, r=0.226) and step width (p 0.37, r=-0.145).

Conclusion: Change in physical activity levels does not have any impact on step length and step width.
