Abstract
Objective-Low cardiorespiratory fitness (CRF) is an independent risk factor for cardiovascular disease (CVD), especially in individuals with type 2 diabetes. Age-predicted, sex-stratified, and maximal MET cut points have been developed to determine the risk of CVD events and mortality in low CRF categories. We examined the proportion of Health Benefits of Aerobic and Resistance Training in IndividualsWith Type 2 Diabetes (HART-D) participants above these cut points before and after 9 months of aerobic training (AT), resistance training (RT), or a combination of both (ATRT). RESEARCH DESIGNANDMETHODSdParticipants from the HART-D study (n = 196) who were randomly assigned to exercise training (AT, RT, or ATRT) or to a nonexercise control group between April 2007 and August 2009 were used in this ancillary study. Cut points were previously established for age-predicted METs (.100% and .85%, mean and increased CVD risk, respectively), age-and sex-stratified METs (Aerobic Center Longitudinal Study), and clinically discernible METs (men .8.0, women .6.5). Results-Baseline prevalence of participants above these cut points was similar for all intervention groups (P . 0.50) and ranged from 11.9% (.100% age predicted) to 55.1% (.85% age predicted). Baseline prevalence and age-, sex-, and race/ethnic group-adjusted percentage of participants above each cut point increased significantly after AT and ATRT (P , 0.05 for all). Conclusions-Structured exercise training, especially the AT component, was associated with a greater number of participantsmoving above established cut points indicative of low CRF. These results have public health and clinical implications for the growing number of patients with type 2 diabetes at high risk for CVD. © 2013 by the American Diabetes Association.
