Abstract

Aim This study compared the effect of different resistance training (RT) frequencies on total, android, gynoid and trunk body fat in overweight/obese older women.

Methods Fifty-seven overweight/obese older women (66.9±5.3 years and 39.9±4.9% body fat) were randomly assigned to one of three groups: a group performing RT twice a week (G2X), a group performing RT three times a week (G3X), or a non-exercise control group (CG). Both training groups performed the same 12-week RT program consisting of 8 exercises that trained all major muscle groups. Dual-energy X-ray absorptiometry was used to assess body composition.

Results After the intervention period, both G2X and G3X demonstrated significant (P<0.05) reductions in adiposity compared to the CG for total body fat (G2X=–1.7%, G3X=–2.7%, CG=+2.1%), android fat (G2X=–6.2%, G3X=–7.0%, CG=+8.6%), gynoid fat (G2X=–2.5%, G3X=–2.9%, CG=+1.0%), and trunk fat (G2X=–2.5%, G3X=–3.0%, CG=+2.9%), with no significant differences between training groups.

Conclusion These results demonstrate that a low-volume 12-week RT program performed two or three times per week causes decreases in total and regional fat deposition with the greatest reductions occurring in the android region.
