Weight Training Reduces Risk of Type 2 Diabetes Mellitus in Men | Heart diseases and Heart Conditions | Scoop.it

Take Home Message: Physicians have recommended a MINIMUM of 150 minues of exercise weekly for diabetic risk reduction but the role resistance training or weight lifting is not certain.  In this study, weight training was associated with a significantly lower risk of Type 2 Diabetes (T2DM), independent of aerobic exercise. Combined weight training & aerobic exercise conferred a greater benefit.

Association of weight training with risk of T2DM in US men & to assess the influence of combining weight training and aerobic exercise, a prospective cohort study of 32 002 men from the Health Professionals Follow-up Study from 1990-2008. Weekly time spent on weight training & aerobic exercise (including brisk walking, jogging, running, bicycling, swimming, tennis, squash, and calisthenics/rowing) was obtained from questionnaires at baseline and biennially during follow-up. 

During 508 332 person-years of follow-up (18 years)

=> 2278 new cases of T2DM

=> dose-response relationship: increasing time spent on weight training or aerobic exercise and lower risk of T2DM (P < .001 for trend)

=> Engaging in weight training or aerobic exercise for at least 150 minutes per week was independently associated with a lower risk of T2DM of 34% (95% CI, 7%-54%) and 52% (95% CI, 45%-58%), respectively.

+> Men who engaged in aerobic exercise & weight training for at least 150 minutes per week had the greatest reduction in T2DM risk (59%; 95% CI, 39%-73%)
