There is a direct linear relationship between intensity of aerobic exercise and VO 2. Our maximum intensity is a reflection of our maximal oxygen consumption (VO 2 max). Such a measurement represents a cardiovascular fitness level. [3] VO 2 is measured in METs (mL/kg/min). One MET, which is equal to 3.5 mL/kg per minute, is considered to be the ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
In an incremental exercise test, it is the first speed at which any increase in exercise intensity fails to elicit an increase in oxygen consumption. The vV̇O 2 max of world class middle- and long-distance runners may exceed 24 km/h or 2:30/km pace ( 15 mph or about 4:00/mile), making this speed slightly comparable to 3000 m race pace.
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 ...
Peak power output (PPO), also known as "peak work rate" is a common measure of exercise intensity.For example, researchers may ask subjects to complete an incremental exercise test where VO 2 max is measured while the person cycles at increasingly difficult power generation levels as measured by a cycle ergometer.
The lactate threshold is a useful measure for deciding exercise intensity for training and racing in endurance sports (e.g., long distance running, cycling, rowing, long distance swimming and cross country skiing), but varies between individuals and can be increased with training.
Generally speaking, adults should aim to get at least 150 minutes per week of moderate-intensity aerobic exercise and two days of muscle-strengthening activity. Even small bouts of exercise can ...
The respiratory exchange ratio (RER) is the ratio between the metabolic production of carbon dioxide (CO 2) and the uptake of oxygen (O 2). [3] [4] The ratio is determined by comparing exhaled gases to room air. Measuring this ratio is equal to RQ only at rest or during mild to moderate aerobic exercise without the accumulation of lactate.
