Treinamento multicomponente com peso corporal melhora a potência, funcionalidade e capacidade de resposta em idosos : um estudo quase experimental

Abstract

The present study aims to verify the effect of multicomponent training with body weight on functional performance in elderly women. The participating group was estimated by sample calculation (n = 27) and after the initial evaluation period was randomly divided into two groups: Experimental Group (n = 15) and Control Group (n = 12). To evaluate explosive force and Lower limb muscle power was evaluated by SJ and CMJ horizontal jumps using the My Jump 2 application as well as a kinematic analysis using the kinovea software of the first 5 repetitions of the sit and raise 30s test. For upper limb power was performed and throwing test with Medicine Ball. To evaluate localized muscular endurance, the Sit and Lift 30s tests for the lower limbs and Flexion Elbow 30s for the upper limbs were used. Finally, to evaluate the agility and dynamic balance, the Time Up and Go tests and the Up and Down Stairs test were used. . The intervention period occurred for 10 weeks, with 3 weekly training sessions being applied, where 2 of these sessions followed the protocol and one session was free, then a new evaluation period was applied. For analysis and results, descriptive statistics were used. and comparison of inter and intragroup measurements, pre and post intervention period through a mixed model of repeated measures (group x time). Significant differences between and within the groups were found predominantly in the lower limb muscle power of the elderly (p = 0.022) and (p <0.001). Regarding upper limb muscle power, the Experimental Group was the only one that presented significant alteration after the intervention period (p = 0.010). There were no statistically significant results for localized muscular endurance and agility and dynamic balance, noting only a correlation between the Climbing Stairs with the SJ (P = 0.017) and CMJ (P = 0.007) and Climbing the Stairs (p) = 0.009) and (p = 0.005) for SJ and CMJ respectively. Thus, it is concluded that Multicomponent Training with body weight is effective in lower limb power, is related to agility and dynamic balance and can generate improvement in localized muscular endurance.
