Effects of a Twelve-Week Weight Reduction Exercise Programme on Selected Spatiotemporal Gait Parameters of Obese Individuals

Abstract

Objectives. This study was carried out to investigate the effects of twelve-week weight reduction exercises on selected spatiotemporal gait parameters of obese individuals and compare with their normal weight counterparts. Methods. Sixty participants (30 obese and 30 of normal weight) started but only 58 participants (obese = 30, normal weight = 28) completed the quasi-experimental study. Only obese group had 12 weeks of weight reduction exercise training but both groups had their walking speed (WS), cadence (CD), step length (SL), step width (SW), and stride length (SDL) measured at baseline and at the end of weeks 4, 8, and 12 of the study. Data were analysed using appropriate descriptive and inferential statistics. Results. There was significantly lower WS, SL, and SDL but higher CD and SW in obese group than the normal weight group at baseline and week 12. However, the obese group had significantly higher percentage changes in all selected spatiotemporal parameters than the normal weight group. Conclusion. The 12-week weight reduction exercise programme produced significantly higher percentage changes in all selected spatiotemporal gait parameters in the obese than normal weight individuals and is recommended for improvement of these parameters among the obese individuals with gait related problems.
