Efficacy of a Motorized Mechanical Oscillator in Abdominal Fat, Weight, and Waist Circumference Reduction - Two Case Studies
動力化機械擺動瘦身器在減少腹部脂肪、體重和腰圍的效力 - 二個專題研究
LANGUAGE NOTE | Document text in English; abstract also in Chinese.
The importance of reducing health risk associated with high abdominal fat is frequently emphasized. Consequently, in Singapore, we have witnessed good sales on motorized mechanical oscillators touted to induce slimming based on the principles of acupressure. However, to date, no study has been done to evaluate the efficacy of such equipment. This pilot study aims to examine the efficacy of motorized mechanical oscillators in reducing waist circumference, weight and abdominal fat percentage over 4 weeks as well as augment the data on acupressure for weight reduction. Two male subjects, one mildly overweight and the other severely overweight, were recruited. They were required to keep to their existing lifestyles and dietary habits and were instructed to wear the oscillator belt for 30 minutes each time, twice a day, as per instructions given in the manual. The machine was operated using the automatic mode. The results show a slight decrease in total body fat % ascertained by DEXA scans. There was also a reduction in waist circumference and an increase in lean mass in the trunk area in both subjects. Specifically, one participant (mildly overweight) lost 1.2% of total body fat, and 0.7cm on the waist girth but gained 1 kg of lean trunk mass. The other participant (severely overweight), although having lost only 0.2% of total body fat and 1.3cm on the waist girth, lost 1.7 kg in total body weight. He also gained in trunk lean mass that resulted in trunk fat reduction of 0.4%. There appears to be some success in such treatment modality particularly with regard to reducing abdominal fat. Certainly, more work needs to be done and future studies are being considered that will involve bigger sample sizes.
