Effect of an accelerometer on body weight and fitness in overweight and obese active duty soldiers.
This study evaluated whether using a web-linked accelerometer, plus mandatory physical training, is associated with various weight- and fitness-related outcomes in overweight/obese active duty soldiers. Soldiers who failed the height/weight standards of the Army Physical Fitness Test (APFT) were randomized to use a Polar FA20 accelerometer device (polar accelerometer group [PA], n = 15) or usual care (UC, n = 13) for 6 months. Both groups received 1.5 hours of lifestyle instruction. We collected data at baseline, 2, 4, and 6 months, and evaluated group differences in temporal changes in study outcomes. At 6 months, 1/28 subjects (UC) passed the APFT height/weight standards. There were no group differences in changes in weight (PA: -0.1 kg vs. UC: +0.3 kg; p = 0.9), body fat (PA: -0.9% vs. UC: -1.1%; p = 0.9), systolic blood pressure (PA: +1.3 mm Hg vs. UC: -2.1 mm Hg; p = 0.2), diastolic blood pressure (PA: +3.8 mm Hg vs. UC: -2.4 mm Hg; p = 0.3), or resting heart rate in beats per minute (bpm) (PA: +7.8 bpm vs. UC: +0.1 bpm; p = 0.2). These results suggest that using an accelerometer with web-based feedback capabilities plus mandatory physical training does not assist in significant weight loss or ability to pass the APFT height/weight standards among overweight/obese soldiers.
