Previous issue date: 2012-03-16 / 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 / O objetivo desse estudo foi verificar a influ?ncia do TF, com frequ?ncia de tr?s sess?es
semanais e dura??o de dez semanas, sobre par?metros cardiovasculares e
antropom?tricos. Trata-se de um estudo de interven??o do tipo antes-depois, cuja
amostra foi composta por 30 indiv?duos. Os mesmos eram adultos com idade
compreendida entre 18 e 40 anos, de ambos os sexos e sedent?rios h? pelo menos
tr?s meses. Foram realizados os testes da ergoespirometria computadorizada, PCR,
VOP e composi??o corporal (vari?veis dependentes), antes e logo ap?s o experimento.
As vari?veis independentes, idade e sexo, foram aferidas no sentido de verificar seus
efeitos sobre as vari?veis dependentes avaliadas. Ao comparar os par?metros
cardiovasculares iniciais com os obtidos ap?s a interven??o nos indiv?duos submetidos
ao TF proposto(atrav?s dos testes t de Student para amostras emparelhadas para os
par?metros que tiveram distribui??o normal e para os que n?o a possu?ram, o
Wilcoxon), n?o houve diferen?a significativa nem na VOP (p =0.469) nem na PCR
(p=0,247), por?m houve aumento no Limiar Anaer?bio (LA) (p=0,004) e no consumo
m?ximo de oxig?nio (VO2m?x) (p=0,052). Em rela??o ?s medidas antropom?tricas, os
indiv?duos diminu?ram significativamente o percentual de gordura (p<0,001) e a massa
de gordura (p<0,001), aumentaram a massa livre de gordura (p<0,001), por?m n?o
alteraram a rela??o cintura-quadril (RCQ) (p= 0,777), massa corporal (p=0,226) nem o
?ndice de massa corporal (IMC) (p =0,212). Os achados do presente estudo nos levam
a crer que o TF proposto, al?m de n?o aumentar a VOP nem a PCR, melhora a
capacidade cardiorrespirat?ria e a composi??o corporal. Portanto, os adeptos de tal
treinamento podem usufruir, com seguran?a, de todos os seus benef?cios sem risco ao
sistema cardiovascular
