文摘

Promoting physical activity is a global strategy to reduce the burden of cardiovascular disease. This study aimed to determine and compare the effect of light resistance training using either dumbbells or ankle-wrist weights on the anthropometric parameters and body composition of adults in Kelantan, Malaysia.

Methods

This randomized community trial was conducted in Kelantan, Malaysia, from March through August 2012. Adults with a body mass index (BMI) of more than 23 kg/m² were randomized into dumbbell (N = 69) and ankle-wrist (N = 69) weight groups. Participants in the dumbbell group performed structured group exercises three times per week using a pair of one-kilogram dumbbells. Participants in the ankle-wrist weight group were given one pair of 500 gm ankle weights and one pair of 500 gm wrist weights to be worn during the activities of daily living three days per week for at least 20 min. BMI, waist circumference (WC), waist-to-hip ratio (WHR), body fat percentage (BF%) and skeletal muscle percentage (SM%) were measured at baseline, week 6, month 3 and month 6.

Results

Eighty-nine participants completed this study. There were significant reductions in BMI only at week six for the dumbbell group. No significant BMI changes were observed for the ankle-wrist weight group. Significant improvements of WC, WHR, BF%, and SM% were observed in both intervention groups from baseline at week 6, month 3, and month 6.

Conclusion

Resistance exercise using either dumbbells or ankle-wrist weights produced significant improvements in certain components of body composition and anthropometric parameters.
