Efeito do alongamento e do exercício contra-resistido no músculo esquelético de rato

Abstract: Objective: To analyze the effect of stretching and resistive exercise on the soleus muscle in rats. Methods: Twenty-four Wistar rats (380±50g) were evaluated, divided into four groups (n=6): C, intact controls; S, left soleus muscle stretched for 40 minutes twice a week; RE, resistive exercise consisting of four series of ten jumps three times a week; and RE+S, resistive exercise plus stretching.After eight weeks, the animals were sacrificed and their soleus muscles were evaluated regarding muscle weight, musc… Show more

“…Some studies have reported that skeletal muscle and connective tissue's morphological adaptations depend on the type, intensity, duration and frequency of the exercises 8,9,29 . The muscular changes depend on mechanotransduction, which is the ability of the cell to sense, process, and respond to mechanical stimuli, regulating the muscle mass 30 .…”

“…Furthermore, stretching and/or resistive training can increase the serial sarcomere number and muscle fiber cross-sectional area of young rats 8,9 . Furthermore, in a recent study with aging female rats submitted to stretching exercise, an antifibrotic action was also detected 10 .…”

“…Além de aumentar a amplitude de movimento articular, o alongamento restaura e/ou mantém o comprimento e o número dos sarcômeros em série, sendo de fundamental importância na hipertrofi a das fi bras musculares e na hiperplasia (15,23). O ajuste no comprimento do sarcômero do músculo auxilia-o no desenvolvimento da tensão máxima, tornando, dessa forma, os exercícios de alongamento uma ferramenta terapêutica frequentemente utilizada na reabilitação física e desportiva (13,15,16,23).…”

“…Não há aumento de fl exibilidade quando a duração do alongamento é aumentada de 30 a 60 segundos, ou quando a frequência de alongamento é aumentada de uma a três vezes por dia (18,23). Corroborando com outros estudos (13,14,18,22,23), optou-se pela realização de apenas uma única sessão de alongamento estático e sua sustentação por um período de 60 segundos, sendo observada sua efi cácia nos alongamentos.…”
