Resumo
O objetivo do estudo foi verificar o efeito crônico do alongamento estático antes
e durante um programa de treinamento da força no desempenho de 8
repetições máximas (8-RM), da flexibilidade e nos níveis sérico-basais de IGF-
1.Trinta voluntários treinados foram divididos aleatoriamente em três grupos:
Grupo Treinamento de Exercícios Resistidos (ER), Grupo de Treinamento com
Alongamento Antes do Treino do Exercício Resistido (AAER), Grupo de
Treinamento com Alongamento Durante o Treino do Exercício Resistido
(ADER). O tratamento experimental foi realizado 3 vezes por semana durante
10 semanas em 4 séries de 8 a 10-RM, com intervalo de 90 segundos, nos
exercícios supino sentado, puxada pela frente, cadeira extensora, mesa
flexora, rosca bíceps e rosca tríceps. Foram realizados testes de flexibilidade,
8-RM e de níveis sérico-basais de IGF-1 nos momentos antes e depois do
tratamento experimental. Após análise dos dados somente o treinamento de
força promoveu aumentos significativos na amplitude articular para ABDO
(9,31%), ADHO (17,82%), RLO (30,15%) e EQ (46,12%). Ao realizar em
conjunto um treinamento de flexibilidade, foram observados aumentos para
ABDO (7,64%), ABDHO (20,12%), RLO (24,20%) e FQ-JF (8,04%). Os
resultados em relação à flexibilidade demonstraram que as articulações do
ombro e do quadril foram positivamente afetadas com a realização de ambos
os protocolos de treinamento com alongamento. Em relação à força, nas
análises intragrupos observaram-se aumentos na força de 20.76% para o
grupo AAER, 14.41% para o grupo ADER e 33.79% para o grupo ER no
exercício puxado pela frente. Em relação ao IGF-1, observaram-se aumentos
significativos nos níveis de IGF-1 no grupo ER. Pode-se concluir que
flexibilidade foi positivamente afetada com a realização dostratamentos
experimentais que utilizaram o alongamento e que o treinamento de força sem
a utilização do alongamento apresentou aumentos significativos nos níveis de
IGF-1.
The aim of the study was to verify the chronic effect of the static stretching before and during a strength training program in the performance of 8 maximum repetitions (8-MR), flexibility, and basal serum levels of IGF-1, thirty trained volunteers were divided randomly in three groups: Training Group of Resisted Exercises (RE), Training Group with Stretching Before the Training of the Resisted Exercise (SBRE),Training Group with Stretching During the Resisted Exercise (SDRE).The experimental treatment was performed three times a week for 10 weeks in 4 sets of 8 to 10-MR, with an interval of 90 seconds, in bench presses in sitting position, pulled for the front in the extension chair, leg curl, biceps curl and triceps curl machine. Tests of flexibility were performed, 8- MR and of serum-basal levels of IGF-1 in the moments before and after the experimental treatment. After analyzing the data only strength training promoted significant increases in range of motion for ABDO (9.31%), ADHO (17.82%), OFR (30.15%) and EQ (46.12%). When conducting a joint training flexibility, increases were observed for ABDO (7.64%), ABDHO (20.12%), OFR (24.20%) and CF-JF (8.04%). Regarding the results of flexibility demonstrate that the articulations of shoulder and hip were affected positively with the accomplishment of both training protocols with stretching. Regarding strength, the analysis intra groups showed increases in strength of 20.76% for the SBRE group, 14.41% for the SDRE group and 33.79% to RE group in the exercise pulled in the front. Regarding IGF-1, significant increases are observed in the levels of IGF-1 in the RE group. It can be concluded that flexibility was affected positively with the accomplishment of the experimental treatments that use the stretching and training strength without using of the stretching presented significant increases in the levels of IGF-1.
