Effect of Exercise and Muscle Contraction on Insulin Action, Transportation and Sensitivity and Muscle Fibres in type II Diabetes Mellitus

This review will critically evaluate the role of exercise in increasing the insulin action, transportation and sensitivity in skeletal muscles. The review will also, try to explore the relationship between the insulin stimulation and glucose transporter type 4 (GLUT-4) protein after the exercise The secondary purpose of this review is to explore whether the exercise induced sensitivity of glucose transport activation is mediated by translocation of greater number of GLUT-4 to the cell surface, and the role of different types of exercise in increasing insulin sensitivity. The review concluded that the stimulation of insulin and exercise is relevant to the physiological developed process of GLUT-4, isoform gene expression is precise and associated with the exercise only. While performing the endurance exercise as well as resistance training we can maintain the muscle bulk and prevent the atrophy in DM. Furthermore, it was proved that the resistance training puts direct effects on the muscles glycogen uptake intracellular and extra cellular signalling pathway and GLUT4, when the subject fed the rich diet of carbohydrate and participates in the exercise. These effects also found in the non-diabetes and healthy subjects.
