Scientific Interest(s):

Dr. Christian Roberts leads the Exercise and Metabolic Disease Research Laboratory (EMDR), which investigates the role of exercise training and diet in the development and prevention of metabolic diseases, including cardiovascular disease and diabetes. Its long-term goals are to investigate:
  1. the efficacy and mechanisms by which novel exercise and diet interventions ameliorate disease risk;
  2. the individual responses to these exercise and diet interventions; and
  3. the impact of metabolic health improvement independent of obesity reversal.
At present, the EMDR has the following grants:
  1. a Tobacco-Related Disease Research Program (TRDRP) New Investigator Award to investigate the effects of resistance training on cardiovascular risk and insulin sensitivity in smokers;
  2. an NIH grant from NHLBI to investigate cardiovascular risk in Mexican Americans and the effects of lifestyle modification in this same population; and
  3. an NIH grant from NIDDK to investigate the efficacy and mechanisms by which a low-glycemic load diet and/or resistance training affects endothelial function, inflammation and glycemic variations.
In addition, the EMDR recently completed a Beginning Grant-in-Aid from the American Heart Association (AHA), Western States Affiliate to investigate the effects of resistance training on cardiovascular risk. These studies incorporate the use of randomized-controlled trial study design and measurement techniques such as DXA for body composition, MRI to determine visceral and organ fat, human monocyte and endothelial progenitor cell isolation and characterization, oral and intravenous glucose tolerance testing, tissue biopsy analyses and ultrasound to estimate brachial artery flow-mediated dilation and echocardiography. The EMDR is very resourceful and a proponent of collaborative research. Its intention is to continue to seek extramural funding that will foster continuous productivity for the EMDR laboratory.
