V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...
Over the course of 12 to 15 minutes, you increase the exercise intensity so that, ... Why does VO2 max decline as you age? ... making your body less energy efficient. VO2 Max by Age Chart.
Ventilatory threshold and lactate threshold are expressed as a percentage of VO 2 max; beyond this percentage the ability to sustain the work rate rapidly declines as high intensity but short duration energy systems such as glycolysis and ATP-PC are relied on more heavily.
VO2 max is a measure of how much oxygen your body absorbs and uses while you work out. (V stands for “volume” while “O2” is for oxygen.) (V stands for “volume” while “O2” is for ...
The body uses different amounts of energy substrates (carbohydrates or fats) depending on the intensity of the exercise and the VO2 Max of the exerciser. Protein is a third energy substrate, but it contributes minimally and is therefore discounted in the percent contribution graphs reflecting different intensities of exercise. The fuel provided ...
The higher your VO2 max, the more oxygen your cardiovascular system can deliver to your muscles - which means they can work harder and last longer.
As a result, an increase in the rate of oxygen consumption is representative of an increase in energy expenditure. VO2 is often measured in absolute terms (ex. Liters/min), but in weight bearing activities, such as running, body mass can have a profound influence on energy expenditure. As a result, it is common to express energy expenditure as ...
A variety of factors can influence your VO2 max, including your gender, genetics, and fitness level—which means you can train to improve your VO2 max, thereby increasing your tolerance for hard ...
