The effect of 2 walking programs on aerobic fitness, body composition, and physical activity in sedentary office employees
Purpose The present study examined changes in body composition , maximum oxygen uptake , and physical activity in sedentary office employees prescribed with two different walking programs during a 10-week intervention . Methods 68 sedentary employees were r and omly assigned to one of three groups : multiple bouts of walking ( n = 24 ( 5 male , 19 female ) Age = 46±9 , BMI = 30.5±5.78 kg/m2 ) , continuous walking ( n = 22 ( 6 male , 16 female ) Age = 48±9 , BMI = 30.6±6.2 kg/m2 ) and the control group ( n = 22 ( 5 male , 17 female ) Age = 42±10 , BMI = 27.5±5.23 kg/m2 ) . Dual-energy X-ray absorptiometry ( iDXA ) assessed body composition and a Bruce protocol treadmill test assessed aerobic fitness at baseline and week 11 . At baseline , week 6 and week 11 a waist worn accelerometer  measured physical activity and sedentary behavior . Physical activity was measured throughout the program with a wrist worn accelerometer . Results The results from the mixed- design ANOVA show that fat mass ( p < .000 ) and fat percentage ( p < .000 ) decreased for all three groups as a main effect of time . Sedentary behavior did not change ( p>0.05 ) for all three groups . Moderate intensity physical activity increased significantly from pre-test to week 6 ( p<0.05 ) , then decreased from week 6 to post-test ( p<0.05 ) , with no significant changes observed from pre-test to post-test ( p>0.05 ) for all groups . No changes in VO2 were observed ( p>0.05 ) for all groups . Conclusions Continuous or intermittent walking activity produce similar benefits on body weight , fat mass and body fat percentage in sedentary employees .  Meanwhile , intermittent walking allowed these sedentary employees to increase lean mass and fat free mass . Intermittent walking could provide at least similar benefits on body composition compared to a continuous walking program
