Mechanisms of Fatigability With Diabetes

Sponsor: University of Michigan

View on ClinicalTrials.gov

Summary

Pre-diabetes (Pre-D) is a precursor to type 2 diabetes (T2D) and characterized by increased exercise fatigability of lower limb muscles, that can impede exercise performance. The cause for the increased fatigability in people with Pre-D is not known. Given the profound vascular disease present in people who have had uncontrolled diabetes for several years, we will determine whether dynamic, fatiguing contractions of the lower limb muscles in people with Pre-D are limited by vascular dysfunction at multiple levels along the vascular tree including the artery, arteriole, and/or capillary. This clinical trial involves a novel exercise training regime involving blood flow restriction to the exercising limb will be used as a probe to further understand the vascular mechanisms for increased fatigability in people with Pre-D and T2D. The long-term goal is to better understand what limits exercise and functional performance in people with diabetes to help develop targeted, more effective exercise programs.

Interventions

OTHER

Control Exercise

Each participant will attend 3 sessions per week for 8 weeks. Participants will perform low-load knee extension resistance training (20% of 1-RM) without blood flow restriction on the designated leg for 4 sets of contractions with 15 contractions per set of contractions with a 30 second rest between each set of contractions.

OTHER

Blood Flow Restriction Exercise

Each participant will attend 3 sessions per week for 8 weeks. Participants will perform low-load knee extension resistance training (20% of 1-RM) with blood flow restriction on the designated leg for 4 sets of contractions with 15 contractions per set of contractions with a 30 second rest between each set of contractions.
