Abstract

The aim of this study was to compare the gross and NET METABOLIC COSTs of walking in a range of specific speeds between obese and normal-weight non- athlete girls. In this study 19 non-athletes were divided into two groups including normal weight (BMI= 21.4±1.4, n=10) and obese (BMI= 32.1±1.7, n=9) groups. To determine the metabolic cost, we measured VO2 and VCO2 while subjects walked on a treadmill at six speeds (0.50, 0.75, 1.0, 1.25, 1.5, 1.75 m/s) 5 minute trails, with a 5 minutes rest between trails). Standing metabolic cost was measured at the beginning of trial, while the subjects had no movement and stayed still on the treadmill. The gross and NET METABOLIC COSTs of obese subjects (4.31±0.8, 3.2±0.6 respectively) were significantly higher than the normal weight subjects (3.13±0.5, 1.2±0.5 respectively) for all speeds. However, when these variables were adjusted for body weight, no significant difference was found between the two groups. The GROSS METABOLIC COST of obese individuals was higher than normal weight individuals. Similar but lower difference was found for NET METABOLIC COST because of less standing metabolic cost for obese group. NET METABOLIC COST for obese individuals shows a greater difference at three higher speeds even when expressed per Kg of body weight which might be due to physiological and mechanical differences of walking in the obese individuals.
