Highlights of Papers in Clinical Investigations Section: Insulin Action After Resistive Training in Insulin‐Resistant Older Men and Women

Aging is associated with decline in peripheral insulin sensitivity, in part because of decreased physical activity and increased central obesity, leading to a high risk for diabetes mellitus. This study assessed the impact of resistive training for 6 months on insulin action and determinants of changes in insulin action in 18 older men and postmenopausal women (11 normal and 7 impaired-glucose-tolerance subjects). Resistive training improved upper- and lower-body muscular strength and increased fat-free mass but did not change total body fat. Insulin action improved with resistive training, especially in subjects with insulin resistance.
