Introduction: According to the definitions of the World Health Organization Overweight and obesity have been described as abnormal or excessive fat accumulation which may impair health. The excess accumulation of abdominal fat (abdominal adiposity) is more associated with complications of the obesity than the excess total body fat. The addition of an exercise training program is a helpful strategy for the management of obesity and related complications. Brisk walking and treadmill walking are the simlplest way of aerobic exercises. Although physical activity and exercise are commonly recommended to reduce overall obesity, the effect of exercise-induced weight loss on abdominal adiposity has been yet to be investigated.

Aim: To compare the effect of treadmill walking and brisk walking on abdominal fat.

Methodology: 40 obese and overweight otherwise healthy men with abdominal circumference >102 cm and BMI (kg/m²) 25-40, age group 18- 40 years were selected for the study. Group – A (20 people did treadmill walking) and group – B (other 20 people did brisk walking) at a speed of 6kmph, 20min/day, 5day/week for 12 weeks. BMI and abdominal circumference were measured and compared before and after the training of 12 weeks.

Results: BMI of both groups is decreased but there was very little difference in decrease in BMI of both groups. Group B (brisk walkers) have slightly more decrease in abdominal circumference as compared to the group A (treadmill walkers).

Conclusion: Brisk walking is more effective way of reducing abdominal fat as compared to treadmill walking.
