Abstract

This paper investigated the effects over time of different forms of neuromuscular training on hemodynamic responses, the estimated VO_2max, and walking performance. 105 older adults were randomly organized into three groups: RG_A, RG_B, and the Control Group (CG). RG_A and RG_B did 4 weeks of adaptation phase training and 12 weeks of intervention with different loads: moderate loads for RG_B. and higher loads for RG_A. A pre- and post-evaluation of the resting heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), double product (DP), estimated VO_2max, and walking performance were assessed. Significant differences were observed for SBP, DBP, HR, and DP. For SBP, a post-evaluation reduction was observed only in RG_A (p = 0.007) and when comparing RG_A with the Control Group (p < 0.000). For the absolute VO_2max, a significant improvement was seen in RG_B compared to RG_A (p = 0.037) and CG (p < 0.000). For the relative VO_2max, RG_B scored significantly higher than RG_A (p < 0.000) and CG (p < 0.000), post-intervention. For the walk test, a significant reduction in completion times was observed for RG_A (p = 0.027) and RG_B (p < 0.000), and for RG_B compared to RG_A (p = 0.000) and CG (p < 0.000). Resistance training can be an excellent strategy for hemodynamic and cardiorespiratory improvement in the elderly.
