The aim of this study is to compare the number of steps, cadence, speed of walk, distance walked, and heart rate of obese women workers during a 30- min walk in two different conditions. The study investigated 15 obese women (45.06 ± 8.42 yrs of age and BMI of 34.94 ± 2.99 kg·m -2 ). Each subject had a session of familiarization and two experimental sessions held at random which consisted of 30 min of walking in a laboratory and outside of a laboratory. During each session of walking the number of steps, cadence, speed, and distance were measured. The data were analyzed using a paired t-test. The alpha level for statistical significance was set at P<0.05). However, there was no significant difference (P>0.05) in heart rate between the two walking conditions (72.02 ± 7.63 and 72.35 ± 7.47, laboratory vs. outside, respectively). Although walking outside was characterized by a different gait pattern from that of walking inside, the heart rate of the subjects was the same.
