Effects of High-intensity Interval Training Treadmill with Changes in Inclination to Body Fat Mass Percentage of Overweight Men

A higher body fat percentage reflects an increased risk of comorbidities. High-Intensity Interval Training (HIIT) is a more efficient and effective form of exercise in reducing body fat mass. This study aimed to determine the effects of HIIT treadmill with changes in inclination to body fat mass percentage of overweight men. Twenty-two overweight subjects who met the study criteria were randomly assigned to the intervention group and the control group. The intervention group did HIIT using a treadmill with incline changes for 4 weeks. Measurements of the anthropometrics such as weight, body mass index (BMI), waist and hip ratio (WHR), and body fat mass were performed pre and post the intervention in both groups. There was significant decrease in body fat mass percentage (p=0,000) and WHR (p=0,000) in intervention group and significant difference in body fat mass percentage (p=0,000) in the intervention group compared to the control group (p=0,00). However, there is no significant decrease in BW (p=0.598) and BMI (p=0.592) in the intervention group after exercise. HIIT treadmill with changes in inclination is good to reduce body fat mass percentage of overweight men
