Beta-blockade and oxygen delivery to muscle during exercise. Hughson RL(1), Kowalchuk JM. Author information: (1)Department of Kinesiology, University of Waterloo, Ont., Canada. The most commonly observed effect of beta-blockade on cardiovascular function has been a reduction in heart rate both at rest and during exercise.Author: Richard L. Hughson, John M. Kowalchuk

Jul 01, 1988 · Endurance during prolonged exercise decreases more markedly with nonselective than betarselective betablockade. Because both types of blockers exert comparable effects on cardiac performance, oxygen supply to the working muscle, and extramuscular substrate mobilization, the difference in exercise capacity is apparently due to other factors.Author: J. Cleroux, F. H. H. Leenen

Results. Age, length of hospitalization, and TBSA burned were similar between groups. In both groups, muscle strength, lean body mass, and VO 2 peak were significantly greater after exercise training than at baseline. The percent change in VO 2 peak was significantly greater in the propranolol group than in the control group (P< 0.05).Author: Laura J. Porro, Laura J. Porro, Ahmed M. Al-Mousawi, Ahmed M.

Apr 08, 2014 · Effects of Beta-blockade on Cardiopulmonary Exercise Testing. ... Several parameters can be measured during CPET, including maximal systemic oxygen delivery, the anaerobic threshold (the oxygen delivery value at which anaerobic metabolism begins), maximum workload, and ST segment depression/elevation (as in a standard exercise tolerance test ...

Oxygen kinetics – start smart for a mean finish! The way your body transports and uses oxygen during the initial stages of vigorous exercise might not sound very exciting, but new research suggests that understanding this process and adjusting your pre-race preparation accordingly can result in truly remarkable performance gains.

Body Adjustments During Exercise to Increase the Delivery of Oxygen to the Working Muscle. During exercise, working muscles have an increased demand for oxygen. Your body makes multiple adjustments during exercise which contribute to provide the necessary oxygen and increased blood flow to the working muscles. These ...

During submaximal exercise, oxygen delivery to muscle is closely tied to the mitochondrial oxygen demand which is driven by the cellular charge (i.e., [ADP + Pi]) provided by the exercise. As mentioned earlier, this same cellular charge also drives other metabolic pathways, notably, glycolysis.
