| Resumo: | This study aimed to determine the influence of strength training (ST), in three weekly
sessions over ten weeks, on cardiovascular parameters and anthropometric
measurements. It is a before and after intervention trial, with a sample composed of 30
individuals. Participants were adults aged between 18 and 40 years, from both sexes
and sedentary for at least three months previously. Tests were computed
ergospirometry, CRP, PWV and body composition (dependent variables) before and
after the experiment. Independent variables, age and sex, were considered in order to
determine their influence on the dependent variablesevaluatedend. By comparing the
initial cardiovascular parameters with those obtained after intervention in patients
undergoing the ST proposed (a Student s t-test was conducted within each group for
samples matched to parameters with normal distribution, while the Wilcoxin was applied
for those without), there was no significant difference in PWV(p =0469) or PCR(p
=0.247), but there was an increase in anaerobic threshold(AT) (p=0.004) and Maximal
Oxygen Uptake(VO2max) (p =0.052). In regard to anthropometric measures, individuals
significantly reduced their body fat percentage (p<0.001) and fat mass (p<0,001), as
well as increasing lean mass (p<0.001). However, no changes were recorded in the
waist-to-hip ratio (WHR) (p= 0.777), body mass (p=0.226) or body mass index (BMI) (p
=0.212). Findings of this study lead us to believe that the proposed ST, and did not
increase the VOP or PCR improves cardiorespiratory capacity and body composition.
Devotees of this training can therefore safely enjoy all its benefits without risk to the
cardiovascular system |
