Efeitos da remobilização em duas semanas com natação sobre o músculo sóleo de ratos submetidos à imobilização

Abstract: Uma importante questão para a reabilitação é como proteger o músculo esquelético dos efeitos da imobilização, pois, o músculo é o mais mutável dentre os tecidos biológicos e responde às demandas normais ou alteradas com adaptações morfológicas e funcionais. O objetivo deste artigo foi verificar o efeito de duas diferentes intensidades de carga de natação sobre a morfologia do músculo sóleo, e se são eficazes para reverter o processo de atrofia causado pela imobilização durante o período de 15 dias. Foram utili… Show more

“…Those findings comply with previous studies that used the same model and presented reduction of sarcomeres along the muscle when animals were submitted to remobilization by swimming, low intensity walk on treadmill or series of static stretch [19][20][21] . Butterfield and Herzog 30 highlighted that tension in the muscle-tendon unit is not the primary source of sarcomerogenesis but it may occur in some cases of eccentric exercise 28 like contractions and disregarded in the present study.…”

“…Tonic muscles like soleus present a greater hypotrophy. That is the reason why devising resources to help people have their optimal movements back is extremely important besides the existing electrical stimulation and physical exercises [17][18][19][20][21][22] . Physical exercise is beneficial to muscle recovery as stated by Malysz et al 23 in his study on muscle recovery of Table 2.…”

“…Several biochemical, metabolic and structural changes are found in muscle disuse related to immobilization (Alves et al, 2013;Volpi et al, 2008). Among them is muscle atrophy, a process that causes loss of strength, gradual decreasing of the activities performed by the patient and metabolism changes (Appell, 1990).…”

“…, Volpi et al 18 , e Gomes et al 2 . Além disso, o processo de imobilização induz a apoptose que acarreta redução no numero de mionúcleos e do conteúdo de DNA, induzindo, por conseguinte, uma atrofia muscular e consequente perda de peso 19 .…”

“…Segundo Volpi et al 18 , duas semanas de remobilização por meio da natação, com tipos distintos de sobrecarga não foram capazes de reverter totalmente o processo de atrofia causado pela imobilização.…”
