Purpose: The purpose of this study was to explore the association of aerobic capacity (V02max) with heart rate variability (HRV), and the influence of exercise beliefs and physical activity recall on these variables in youths with type 1 and type 2 diabetes. We also compared V02max and HRV in adolescents with type 1 versus type 2 diabetes. Conceptual Framework: The framework is predicated on biobehavioral linkages in health outcomes, particularly the influence of health beliefs and practices on health status. Subjects: 45 adolescents with type 1 (16.4 ± 1.9 yrs.) and 11 adolescents with type 2 diabetes (16.6 ± 1.8 yrs) participated. BMI was 24.2 ± 3.9 vs. 36.0 ± 13.1 for those with type 1 and type 2 diabetes, respectively (P=.001). Methods: Aerobic capacity was measured by obtaining VO2max values using the McMaster Cycle Test and Sensormedics® VMAX29 cardiopulmonary metabolic cart. HRV was measured following exercise testing by using Spacelabs Burdick Vision Premier SoftwareTM for 24-hour Holter recording analysis. Metabolic control (hemoglobin A1c) was determined by cation exchange chromatography. Results: Cardiovascular endurance (V02max) was associated with metabolic control, physical activity recall and exercise beliefs (P < .05) in adolescents with type 1 diabetes. HRV was associated with V02max (P < .01) and exercise beliefs (P < .05) in adolescents with type 1 diabetes. V02max values were significantly lower in adolescents with type 2 diabetes (27.5 ± 6.7 vs. 36.2 ± 9.1, P < .01). Although nonsignificant, HRV measures were lower in adolescents with type 2 diabetes. Conclusions: Increased V02max appears to be positively influenced by better glucose control, physical activity, and beliefs about exercise in youths with type 1. Greater modulation of HRV may be a benefit for those with increased V02max. Additional research is needed to support these relationships in both type 2 and type 1 diabetes. AN: MN030077
