Resumo: Neuromuscular electric stimulation by Russian current, used in rehabilitation, is able to increase muscle trophism and strength, especially in muscles with post-immobilization deficit, as is the case of injuries during sports practice. The purpose here was to assess the gastrocnemius muscle mechanical properties of rats immobilized for 14 days and subjected to electric stimulation by Russian current for 10 days. Thirty two Wistar female rats were divided into four groups: control (G1), immobilized (G2), immobilized and freed (G3), and immobilized and afterwards submitted to Russian current (G4). Mechanical properties - maximum load and stretch, stiffness, and resilience - were assessed by longitudinal traction. As to maximum load, G4 showed higher values when compared to the only-immobilized group (G2, p

Objetivou-se avaliar as propriedades mecânicas do músculo gastrocnêmio de ratas imobilizadas por 14 dias e posteriormente submetidas à eletroestimulação por corrente russa durante 10 dias. Utilizaram-se 32 ratas Wistar divididas em quatro grupos: controle (G1), imobilizado (G2); imobilizado e liberado por 10 dias (G3) e imobilizado e submetido à corrente russa por 10 dias (G4). A avaliação das propriedades mecânicas - carga, alongamento, rigidez e resiliência - foi feita por ensaio de tração longitudinal. Quanto à carga no limite máximo, o G4 apresentou valores mais elevados quando comparado ao grupo apenas imobilizado (G2, pUniversidade de São Paulo.
