Document Summary
Attribute of characteristics, endurance, ability to sustain work for a long period of time. How well & long we can do work. Inversely related to all-cause death, heart disease, chf death, diabetes. 1 met increase in fitness = 10% decrease in mortality. Can be used to monitor training progress. The fitter you are, the healthier you are. Heart pumps deoxygenated blood to the lungs. Heart pumps oxygenated blood to the muscle. Heart receives deoxygenated blood from the muscles. Outside air body lungs heart muscle mitochondria. Once in mitochondria it is used to produce energy. We can increase a-vo2 by increasing capillary density. Needed to be accepted to increase blood blow. Slows red blood cell transit allowing for enough time for oxygen diffusion. Vo2: the volume of oxygen consumed during pa. Q = cardiac output (hr * stroke volume) Stroke volume = amount of blood ejected from the heart. Measure ventilation, carbon dioxide, and oxygen using metabolic cart.
