The AlterG Anti-Gravity Treadmill allows individuals to walk at reduced body weight by using lower body positive pressure (LBPP). PURPOSE: The purpose of this study was to discern if the AlterG Anti-Gravity Treadmill was an effective tool to use in a weight loss walking program with obese individuals when compared to walking on a traditional treadmill. METHODS: Fifteen male (n = 3) and female (n = 12) obese participants, aged 18-55 years old with an average body mass index [BMI] ≥ 30 kg/m2), were randomly assigned to the AlterG treadmill (AlterG; n = 6) and traditional treadmill (TT; n = 9). Participants followed an 18-week (three 6-week phases) weight loss walking protocol and exercised 3 days a week. Each 6-week phase increased in intensity and duration, and by Phase 3 participants were walking at an intensity of 60-85% HRmax for 60 minutes. The participant’s weight, BMI, and body fat percentage (BFP) were recorded during the program. RESULTS: There was no significant overall weight loss difference determined between the two groups. The AlterG and the TT group lost an average of 2.33 kg and 2.14 kg, respectively. Similarly, no significant overall differences in BMI and BFP were found between the two groups. Significant differences were found among the three phases of the weight loss intervention for weight loss (p = 0.024), BMI reduction (p = 0.021), and BFP reduction (p < 0.0005). Each group exhibited significant decreases in weight, BMI, and BFP by the conclusion of the study. CONCLUSION: This study demonstrated that the walking protocol used with the AlterG Anti-Gravity Treadmill was effective to produce significant weight loss, decreased BMI, and reduced percent body fat in obese individuals.
