Effects of Single Set Resistance Training With Different Frequencies on a Cellular Health Indicator in Older Women.

Effects of Single Set Resistance Training With Different Frequencies on a Cellular Health Indicator in Older Women. J Aging Phys Act. 2017 Nov 28;:1-23 Authors: Ribeiro AS, Nascimento MA, Schoenfeld BJ, Nunes JP, Aguiar AF, Cavalcante EF, Silva AM, Sardinha LB, Fleck SJ, Cyrino ES Abstract The main purpose of this study was compare the effects of resistance training (RT) performed two versus three times per week on phase angle (a cellular health indicator) in older women. Thirty-nine women (69.1±5.5 years) were randomly assigned to perform a RT program two (G2X) or three (G3X) days per week for 12 weeks. The RT was a whole-body program (8 exercises, 1 set, 10-15 repetitions). Phase angle, resistance, reactance, and total body water were assessed by bioimpedance spectroscopy. Intracellular water, reactance, and phase angle increased significantly in G2X (2.1%, 3.0%, and 5.6%, respectively) and G3X (5.0%, 6.9%, and 10.3% respectively) from pre- to post-training, with no significant difference between groups. Bioimpedance resistance decreased similarly in both groups (G2X=-1.7% vs. G3X=-3.2%). We conclude that a single set RT program with a frequency of two days per week may be sufficient to promote an improvement in cellular health in older women.
