exercise capacity

max·i·mal ox·y·gen con·sump·tion

(mak'si-măl ok'si-jĕn kŏn-sŭmp'shŭn)
Highest amount of oxygen a person can consume during maximal exercise of several minutes' duration. It is demonstrated by a leveling off or decline in oxygen consumption with increasing intensity.
Synonym(s): aerobic capacity, aerobic power, maximal oxygen uptake, VO2max.

exercise capacity

The ability of a person to increase oxygen uptake above his or her oxygen uptake at rest. While lying comfortably in bed each individual's body uses a basal (resting) level of oxygen to perform basic metabolic functions. This level of oxygen usage is referred to as one metabolic equivalent, or informally, as 1 MET. While walking on level ground the average person doubles his oxygen uptake, that is, his oxygen uptake increases to 2 MET. Higher levels of exercise (such as jogging) can only be achieved by individuals with greater exercise capacity; jogging at 6 miles per hour requires 6 MET. Highly trained athletes can achieve 15 MET or more. Studies have shown that the lower one's exercise capacity, the more likely that person is to die from heart disease.

The primary measure of efficacy is change in peak oxygen uptake as assessed by cardiopulmonary exercise testing (CPET), a quantitative measure of exercise capacity. Secondary efficacy measures include change in exercise capacity as assessed by the six-minute walk test, and change in patient-reported quality of life as assessed by the Kansas City Cardiomyopathy Questionnaire
The topics are spirometry: dynamic lung volumes, static (absolute) lung volumes, diffusing capacity of the lungs, bronchodilators and bronchial challenge testing, arterial blood gases, other tests of lung mechanics: resistance and compliance, the distribution of ventilation, maximal respiratory pressures, preoperative pulmonary function testing, simple tests of exercise capacity, patterns in various diseases, when to test and what to order, interpreting pulmonary function tests, and illustrative cases.
In HFpEF, the wall of the left ventricle is too stiff to fully fill with blood, resulting in diminished exercise capacity. There are currently no drugs available to treat HFpEF, but scientists have observed that metformin, when taken by people with diabetes, increases left ventricular dilation and lowers the rate of heart failure.
METEORIC-HF is designed to assess the effect of treatment with omecamtiv mecarbil compared to placebo on exercise capacity as determined by cardiopulmonary exercise testing (CPET) in patients with HFrEF.
The study further confirmed that all exercise variables included in estimating physiological age were powerful predictors of survival, including exercise capacity, chronotropic competence (heart rate response to exercise) and heart rate recovery.
The equation uses exercise capacity, how the heart responds to exercise (chronotropic competence), and how the heart rate recovers after exercise.

No changes in endurance exercise capacity and hormonal profile were observed after Rhodiola ingestion.

FRIDAY, June 29, 2018 (HealthDay News) -- A three-pronged approach to prehabilitation, which includes improving nutritional status, exercise capacity, and worry reduction, may improve outcomes after cardiac surgery, according to a study published online June 27 in the Canadian Journal of Cardiology.
