Strength training is the most effective lifestyle interventionto increase muscle mass but limited data is available in older adults with diabetes. We determined the influence of strength training on muscle quality strength per unit of muscle mass skeletal muscle fiber hypertrophy and metabolic control including insulin resistance Homeostasis Model Assessment -HOMA-IR C-Reactive Protein CRP adiponectin and Free Fatty Acid FFA levels in Hispanic older adults. Sixty-two community-dwelling Hispanics 55 y with type 2 diabetes were randomized to 16 weeks of strength training plus standard care ST group or standard care alone CON group . Skeletal muscle biopsies and biochemicalmeasures were taken at baseline and 16 weeks. The ST group show improved muscle quality mean SE 28 3 vs CON -4 2 p and increased type I 8601252pm2 and type II fiber .
