Abstract Phil LaScola., Ph.D., August 2015 School of Health Sciences PHYSIOLOGICAL RESPONSES TO COUNTERWEIGHTED SINGLE-LEG CYCLING IN AN ELDERLY POPULATION (67 pp.) Director of Dissertation: John McDaniel, Ph.D. Co-Director: Ellen Glickman, Ph.D. INTRODUCTION: Single-leg cycling allows for a greater muscle specific exercise capacity and therefore provides a greater stimulus for metabolic and vascular adaptations when compared to standard double-leg cycling. PURPOSE: The purpose of this investigation was to compare the metabolic, cardiovascular, and peripheral responses of single-leg cycling with a counterweight to double-leg cycling in a healthy elderly adult male population. METHODS: Eleven healthy males (age 66 ± 8 years) performed two cycling conditions consisting of double-leg cycling (DL) and single-leg cycling with a 97N counterweight attached to the unoccupied crank arm (CW). For each condition, participants performed cycling trials (60rpm) at three different work rates (25, 50, 75 W) for 4 minutes each. Oxygen consumption (VO2), respiratory exchange ratio (RER), heart rate (HR), mean arterial pressure (MAP), femoral blood flow, rating of perceived exertion (RPE), and liking scores were recorded. RESULTS: HR was similar between DL and CW conditions at all three intensities. VO2 was similar between DL and CW at 25W and 50W, however, at 75W VO2 was greater during the CW condition compared to DL (p= 0.037). Femoral artery blood flow was significantly greater during CW cycling for the 50W and 75W work rates (p= 0.01, and p<0.001). RPE and liking were similar between both conditions (p= 0.065, p= 0.060). CONCLUSION: At least at low and moderate intensities, counterweighted single-leg cycling provides a greater peripheral stress for the same cardiovascular demand as double-leg cycling in a healthy elderly adult male population. Furthermore, enjoyment of single-leg cycling was similar to double-leg. Thus, single-leg cycling with a counterweight may be a feasible exercise modality for a diseased population (i.e. peripheral vascular disease/cardiovascular disease).
