title: Resistance training prescription with different load-management methods improves phase angle in older women.
abstract: The purpose of the present study was to investigate the effect of two different resistance training (RT) prescription methods on phase angle (PA) in older women. Seventy-six older women (68.5 ± 5.7 years) were randomly assigned to one of three groups: two training groups that performed an eight-week RT programme either in a constant load (CT, n = 25) or an ascending pyramidal load (PR, n =  26) routine three times per week, or a control group (CG, n =  25) that performed no exercise. The CT programme consisted of three sets of 8-12 repetition maximum (RM) with a constant load for the three sets, whereas the PR training consisted of three sets of 12/10/8 RM with incremental loads for each set. PA was assessed by whole-body spectral bioelectrical impedance. After the RT period, both CT and PR achieved higher (P < .05) values of PA (CT =  5.76 ± 0.59°, PR =  5.63 ± 0.61°, CG =  5.48 ± 0.46°) compared to the CG; however, there was no difference (P > .05) between trained groups. The results suggest that eight weeks of RT based on a PR and CT load routines promote an improvement in PA, and both prescription methods performed similarly.
