A influência do ultrassom e do treinamento físico sobre os triglicérides séricos e intramusculares em ratos diabéticos experimentais

Abstract

Therapeutic ultrasound is seen today as one of the most useful resources in the practice of clinical medicine and physical exercise is consolidated as an effective and efficient therapeutics in several cases; however, they are still little investigated when associated. Therefore, the present work has as the aim to analyze the influences of ultrasound and physical exercise on serum and muscle triglycerides concentrations in experimental diabetes rats. Adult Wistar rats were used and divided in eight groups: Sedentary Diabetics (SD), Trained Diabetics (TD), Sedentary Diabetic and Ultrasound (SDUs), Trained Diabetic and Ultrasound (TDUs), Sedentary Control (SC), Trained Control (TC), Sedentary and Ultrasound Controls (SUCs), Trained Control and Ultrasound (TCUs). The training protocol was composed of swimming exercise five days a week, 30 daily minutes and with maximum load of 8% of body mass during three weeks. The ultrasound therapy was performed five days a week, for two weeks, with intensity of 0.2W/cm² and frequency of 1.0MHz. No significant differences were observed in the serum triglycerides or in the tibialis anterior and gastrocnemius muscles. Concerning the soleus muscle, the diabetic groups showed lower concentrations compared to the control groups and TD, and TDUs groups showed lower concentrations compared to SD and SDSU, with the trained groups presenting the lowest concentrations. The pulsed ultrasound in the intensity investigated did not influence serum triglycerides or IMTG. However, exercise was effective in reducing soleus muscle triglycerides.

Efeito do ultrassom terapêutico sobre as propriedades mecânicas do gastrocnêmio em ratos

“…Dentre elas, o ultrassom terapêutico (UST) é uma modalidade frequentemente empregada no meio clínico para aceleração do reparo tecidual e para tratamento de diversos distúrbios músculoesqueléticos em atletas tais como dor, contraturas articulares, tendinites, bursites, espasmos e contusões musculares [3][4][5][6][7][8] .…”
