S keletal muscle mass, which is mostly located in the lower body, constitutes approximately 40% of fat-free body mass in young adults 1 but decreases with advancing age, especially after the fifth decade of life. 2 These age-related changes lead to a decline of strength and power, a decrease in physical performance, and disability. 3 Because the population of elderly people is growing in most countries, including Japan, the agerelated loss of skeletal muscle mass is likely to have a severe economic impact on the healthcare system.Age-related loss of skeletal muscle mass (Sarcopenia) has been studied extensively by evaluating muscle volume, muscle cross-sectional area (CSA), and anatomical muscle thickness (MTH). 4 Recently, Abe and colleagues demonstrated that age is associated with site-specific loss of skeletal muscle mass in Japanese men and women 5,6 and in German men 7 . Interestingly, in the anterior and posterior regions of the thigh, age-related muscle loss was observed in the quadriceps but not in the hamstrings and adductors. 8 The etiology of sitespecific sarcopenia is multifactorial and complex. Several factors have been implicated such as declining anabolic hormone concentrations, nutritional deficiencies, chronic inflammation, and insulin resistance. 5,7 Decreased physical activity levels that occur with aging also contribute to sarcopenia. It is well established that hormonal receptors for mRNA and transcriptional activity are increased 8 and that there is reduced insulin resistance 9 in exercising muscles following an acute bout of exercise for sedentary individuals. There are therefore many important interrelationships between physical activity levels and other etiologic factors associated with health and aging that may contribute in varying degrees to the age-related loss of skeletal muscle mass in older populations. More recently, we examined the effect of habitual physical activity on age-related loss of skeletal muscle and found that there is site-specific loss in both active (more than once a week) and inactive old women. 10 In that study, the subjects were classified into active and inactive groups based on their self-reported habitual physical activity. The effect of exercise intensity and duration of daily physical activities on site-specific loss of thigh muscle is unknown. However, muscle mass and strength losses associated with increasing age

The study compared effects of maximal resistance training (MRT) versus endurance resistance training (ERT) in overweight people at risk of developing Type 2 Diabetes. Dependent variables included changes in body fat %, upper leg skeletal muscle area (left + right), BMI and body weight pre-to post intervention. Eighteen individuals, 33-69 years of age, were randomly assigned to one of two groups. Group 1 engaged in MRT three days/week over a four month period while members of Group 2 acted as controls. Later, Group 2 engaged in ERT three days/week over a four month period and the members acted as their own controls. Both interventions consisted of eight exercises. Pre-to post changes were significant for MRT with a reduction in BMI (p=0.013) and body weight (p=0.010), while percentage of body fat was significantly reduced (p=0.009) and skeletal muscle area increased (p=0.021) with ERT. The results support both approaches as interventions in primary prevention of obesity and consequently in reducing risk of Type 2 Diabetes.

Abstract-Introduction: There is compelling evidence that type 2 diabetes mellitus (T2DM) is more likely to develop in individuals who are insufficiently active. Resistance exercise (RE) has received high recognition as a cornerstone in the management of T2DM. There are several advanced research about RE. However, those do not use rubber band during exercise. Therefore, the purpose of this study was to examine the effect of rubber band resistance exercise on blood glucose level of the patient with T2DM. Methods: The research design was one group pretestposttest design (rubber band resistance exercise) as the treatment given to the patient with T2DM. Fifteen participants were randomly selected from PHC 2 South Denpasar, Bali, in March 2017. Each participant was given exercise using the rubber band in groups carried out every day with a duration of 30 minutes for a week. Blood glucose level was measured by using blood glucose test before and after the intervention. Results: The result showed rubber band resistance exercise was statistically significant decrease the level of blood sugar by 25.43 mg/dl, (p < 0.05). Discussion/Conclusion: Resistance exercise using the rubber band is an alternative form of exercise for the T2DM patient. There is good evidence that rubber band resistance exercises improving glycemic control patients with T2DM.
