Effect Of Beta-Adrenergic Blockade On Coronary Blood Flow During Isometric Exercise In Older Adults, A. Ross, Z. Gao, M. Heffernan, U. Leuenberger, L. Sinoway, M. Muller

International Journal of Exercise Science: Conference Proceedings

Ross A., Gao Z., Heffernan M., Leuenberger U., Sinoway L., Muller M. Penn State Hershey Heart and Vascular Institute, Pennsylvania State University College of Medicine, Hershey, PA

The rise in heart rate (HR) and cardiac contractility during exercise is due to activation of myocardial b-adrenergic receptors. b-receptors are also located on coronary blood vessels and are thought to participate in exercise hyperemia, thereby helping to preserve the balance between myocardial oxygen supply and demand. However, experimental data in human subjects are lacking. Purpose: We hypothesized that intravenous b-adrenergic blockade would attenuate the reflex tachycardia and coronary hyperemia in response to …

Increased Frequency Of Moderate Intensity Walking Increases Consumption Of Low Energy Density Foods, L. Panek-Scarborough, J. Temple

International Journal of Exercise Science: Conference Proceedings

Panek-Scarborough, L., Temple, J., University at Buffalo, Buffalo, NY

Figure 1: Mean + SEM change in laboratory energy consumed from pre to post exercise intervention from HED foods (top) and LED foods (bottom). The 5 day/week group consumed significantly more energy from LED food from pre- to post-exercise treatment (p = 0.002) compared to the other groups.

Background: There is evidence that exercise has an effect on the type and amount of food consumed. One factor that regulates eating is the reinforcing value of food. While previous studies have demonstrated interactions between exercise and eating, to date, no one has …

Metabolic Demand And Nutrient Resource In Rowing Ergometer And Treadmill Exercise, E Burns, D. Burns

International Journal of Exercise Science: Conference Proceedings

Burns, E., Burns, D. DeSales University, Center Valley, PA

Purpose: Rowing ergometer exercise differs from treadmill exercise in two ways. Treadmill exercise utilizes primarily the lower extremities and is a load-bearing activity. Rowing is a seated activity and utilizes a much greater muscle mass. This study compared metabolic responses to these two exercise modes at differing submaximal intensities. Methods: Twelve healthy college-age males completed one exercise exposure on a treadmill and one on a rowing ergometer. Metabolic steady state was achieved during each stage of exercise at intensities approximating 4, 6, and 8 MET. Oxygen consumption, respiratory exchange ratio (RER), …

Effects Of A High Speed-Low-Resistance Bicycling Intervention In Parkinson’S Disease, M. Bellumori, M. Uygur, C.A. Knight

International Journal of Exercise Science: Conference Proceedings

Bellumori, M., Uygur, M., Knight, C.A. University of Delaware, Newark, DE

Bradykinesia is a symptom of Parkinson’s disease (PD) that substantially decreases mobility while contributing to increased rates of disability and health care costs. Bicycling exercise is a promising strategy that could improve mobility in PD. Purpose: To determine the effects of a six week exercise intervention that uses high speed- low-resistance (HS-LR) stationary recumbent cycling in people with PD. Methods: Pre-exercise tests assessed level of PD severity, physical function, and perceived health. These were again performed following a supervised, 6-week (12 sessions), HS-LR program. Results: Eleven participants (age 62.7 …
