BACKGROUND AND METHODS: To evaluate the physiologic basis for the suboptimal peak oxygen uptake observed after heart transplantation, we calculated the functional aerobic impairment ([(peak predicted oxygen uptake-peak observed oxygen uptake)/peak predicted oxygen uptake] x 100) and related it to donor/recipient, operative, and maximal exercise variables. Fifty-seven heart transplant recipients ...

The Type A behaviour pattern is a well-documented, if controversial, risk factor for coronary heart disease. Surprisingly, relatively little work has been reported on ways of modifying this behaviour pattern. Aerobic exercise, with its demonstrated benefits for both cardiovascular reactivity and psychological 'well-being', is a promising treatment. The literature is ...

Aerobic fitness and aerobic endurance are two separate components of aerobic metabolism. Aerobic fitness, best measured by VO2max, is a measure of oxygen transport and utilization. Aerobic endurance is not measured in a VO2max test because it does not measure the ability of the muscle to perform prolonged work. Endurance ...
