Abstract
The importance of reducing health risk associated with high abdominal fat is obvious. In Singapore, we have witnessed good sales on motorized mechanical oscillators touted to induce slimming. Such equipment works on the principles of acupressure. No study has yet been done to evaluate the efficacy of the mechanical oscillator; thus it is the aim of this study to examine the efficacy of the mechanical oscillator and to provide the data on acupressure for weight reduction, and more specifically abdominal fat reduction.
33 male (age 21-35; BMI > 23kg/m2) participants were recruited and randomly assigned to the control and treatment group. Participants in the treatment group used the oscillator for an hour a day for 28 days. They were required to record their daily food consumption and physical activity in a log sheet during the treatment period. All data were analyzed using SPSS version 14.0. MANOVA was used for the between-groups analysis and one-way repeated measures ANOVA was used for the within-group analysis.
There was no significant difference in the outcome variables between the two groups. However, there was a significant reduction in abdominal fat within the treatment group. However,it was found that some individuals reported reductions in abdominal fat though no significant overall results were found. In conclusion, the mechanical oscillator cannot be used to replace physical activity for weight loss or maintenance.
