Effect of Using Tri-axial (3D) Sensor-Assisted Pedometer Measuring Moderate- To High-Intensity Physical Activity on Body Composition: Randomised Controlled Trial

Objective: We investigated the effect of tracking recommended dose of physical activity with pedometer on body composition. Methods: Participants were randomly assigned to control, walking (PAC) and pedometer (PAC-PED) groups, and moderate- to high-intensity physical activity was prescribed. The partcipants performed the recommended exercises in PAC group by taking notes on follow-up cards, in PAC-PED group by pedometer, and in control group without a follow-up. Results: A total of 50 participants, 23 in the control group, 11 in the PAC group and 16 in the PAC-PED group, were completed. The average age of all participants was 47,1 ± 12,8 (25 - 81), the proportion of women and men was 74% and 26%, respectively. The mean body mass index of the participants was 29,7 ± 5,5 kg / m2 and body fat ratio was 33,8 ± 8,5. Participants were followed up for an average of 2,0 ± 1,2 [0,5 – 6,3] months. There was a significant decrease in body weight in all groups. Body fat percentage did not change in the control group, but significantly decreased in the PAC and PAC-PED groups. Conclusion: Individualized follow-up by card in patients with personalized physical activity reduces body fat ratio while individual follow-up by pedometer reduces body fat ratio even more. Body fat ratio does not change when individual follow-up is not performed
