Subjects with type 2 diabetes will be stratified into two-quantiles based on ambient hyperglycemia (fasting glucose and HbA1c) and then the effects of a single aerobic exercise bout (1-hour at 50%VO2max) on pancreatic endocrine function will be determined.

Condition Intervention
Type 2 Diabetes
Behavioral: Exercise

Study Type: Interventional

Primary Outcome Measures:
  • Pancreatic endocrine function [ Time Frame: 24-hours following a period of rest/exercise ]
    Insulin and glucagon secretory responses to intravenous glucose (hyperglycemic clamp 5.4 mmol/l above basal), glucagon-like peptide-1 (0.5 pmol/kg/min), and arginine (5 g injection) will be determined.

Enrollment: 14
Study Start Date: January 2013
Study Completion Date: October 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Resting Trial
Pancreatic endocrine function will be determined the morning following a day where no exercise is performed
Experimental: Exercise Trial
Pancreatic endocrine function will be determined the morning following a day where a 1-hour aerobic exercise is performed at 65% of pre-determined HRmax (maximal heart rate measured during an incremental work-load exercise test to volitional exhaustion)
Behavioral: Exercise
