Influence of resistance training on cardiorespiratory aptitude in elderly people
Abstract
Much is already known about the effects of resistance training on young people. However, there are still questions regarding its influence on cardiorespiratory system improvements, especially in older individuals. Thus, the present study has the objective of verifying the influence of resistance training on the cardiorespiratory aptitude of elderly people. 10 sedentary individuals of both sexes, aged 69± 5.4 years, participated in the study. Their mass, height, isokinetic strength and oxygen consumption ina submaximal cardiorespiratory stress test were measured before and after five months of resistance training. In order to compare the variables that were observed, a T test for repeat measurements was used and the level of significance was established as p≤ 0.05. There was a significant reduction of relative (p=0.003) and total (p=0.002) oxygen consumption for the same expenditure of effort, considering that there was no obvious change between tests in the time spent on the evaluation (p=0.08). There was no significant increase of isokinetic strength after the five months of training. We conclude that resistance training may be considered an efficient means for developing aerobic capacity in elderly people, at least for the more fragile individuals.
