Clinical Trial Summary

This parallel-arm trial study investigates the effects of restricting arterial blood flow during cycling exercise on citrate synthase. Participants will be randomized to either a blood flow restricted or non-blood flow restricted exercise training group. Both groups will complete seven, 30-minute exercise sessions over a 14-day period.
