Resumo
O treinamento concorrente tem sido amplamente utilizado em academias
e em alguns esportes, sendo realizado por diversas populações. Contudo,
poucos estudos avaliaram a resposta hormonal de homens treinados
conjugando um exercício do treino aeróbio com o exercício de força. Com isso,
o objetivo deste estudo é observar o efeito do treinamento concorrente na
resposta hormonal aguda (testosterona, cortisol, hormônio do crescimento e
IGFBP-3 de homens treinados. Vinte homens treinados (24±5 anos) foram
divididos em 2 grupos: treino aeróbio mais força (AF, n=10) e treino de força
mais aeróbio (FA, n=10). Cada grupo treinou uma única sessão de
treinamento. Antes do período de treino, os sujeitos foram avaliados em
parâmetros relacionados à força muscular, teste de 1RM, capacidade aeróbia,
teste de lactato. Antes e após a sessão de treino era realizada a coleta
sanguínea. Os resultados mostraram que houve diferença significativa nos
níveis de cortisol pré e pós (G1=11,55±6,52 e 15,43±6,59) comparado ao (G2=
19,81±6,98 e 31,40±14,89) respectivamente, em que FA apresentou um
aumento mais acentuado entre momentos. Houve aumento significativo de
testosterona ao longo do tempo, independentemente da ordem de conjugação
do exercício aeróbico com exercício de treino de força. Em relação à razão
testosterona/cortisol, constatou-se que existe uma tendência idêntica na
diminuição em ambos os grupos. Houve uma interação inversa nos níveis de
IGFBP-3, (G1=4809,20±792,68 e 5573,00 ±1276,64) enquanto no AF
demonstrou um aumento, no FA ocorreu uma diminuição (G2= 5,073±803,69 e
4660,00±979,82), sendo que ambas foram significativas. Ainda, houve um
aumento significativo nos níveis do hormônio do crescimento em ambos os
grupos, sem diferença entre eles. Os presentes resultados demonstraram que
as respostas hormonais agudas, nas diferentes ordens de conjugação de
exercícios apontaram diferentes resultados. Assim, quando se tem que juntar
na mesma sessão de treino, exercícios de TF e exercícios predominantemente
aeróbios, e o objetivo é a manutenção da massa muscular, parece que os
exercícios aeróbios devem vir antes dos exercícios de TF.
The concurrent training has been widely used in gyms and some sports, being performed by several peoples. However, few studies have evaluated the hormonal response of trained men combining an exercise of the aerobic training with the strength exercise. Thus, the aim of this study is to observe the effect of the concurrent training on acute hormonal response (testosterone, cortisol, growth hormone and IGFBP-3) of trained men. Twenty trained men (24 ± 5 years old) were divided into 2 groups: aerobic training plus strength (AS, n = 10) and strength training plus aerobic (SA, n = 10). Each group trained a single training session. Before the period of the training, the subjects were evaluated on parameters related to muscle strength, test of the 1RM, aerobic capacity, test of the lactate. Before and after the session of the training the collect of blood was done. The results show a significant difference in the levels of cortisol before and after (G1=11,55±6,52 and 15,43±6,59) compared the (G2= 19,81±6,98 and 31,40±14,89) respectively, in which SA had an increase, more emphasized between moments. There was a significant increase in testosterone over time, regardless of the order of combination of the aerobic exercise with exercise of training of strength. In relation to testosterone/cortisol there is a similar trend in the reduction in both groups. There was an inverse interaction in the levels of IGFBP-3, while the AS showed an increase (G1=4809,20±792,68 and 5573,00±1276,64) in the SA there is a decrease, (G2= 5,073±803,69 and 4660,00±979,82), and both were significant. There was still a significant increase in the levels of the growth hormone, in both groups, with no difference between them. The present results demonstrate that the acute hormonal responses in different orders of combining of exercises show different results. So when it has to join in the same training session, exercises strength training and predominantly exercise aerobic, and the goal is to maintain muscle mass, it seems that aerobic exercise should come before the strength training.
