Strength Training's Preventative Capabilities
There is an emerging body of evidence (listed below) that suggests that resistance training can be viewed as a beneficial preventive measure for risk factors related to type 2 diabetes mellitus in overweight and obese older men and women. More specifically, it is well established that physical inactivity (sedentary lifestyle) is an important contributor to the deterioration of insulin sensitivity with advancing age, through its consequences on loss of muscle mass and muscle strength, as well as increased fat mass. A physical activity regimen focusing on strength training in combination with aerobic exercise can be beneficial through ameliorating the age-related loss of metabolically active muscle tissue which has been shown to be an important determinant of glucose tolerance. Therefore, Lift for Life, an evidence-based strength training program designed for those with or at risk of diabetes, may be a practical public health program to employ for the prevention of diabetes and a healthier lifestyle.
