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 ...
As the intensity level of the activity being performed increases, breathing becomes faster; more steadily first and then more rapid as the intensity increases. When breathing surpasses normal ventilation rate, one has reached ventilatory threshold. For most people this threshold lies at exercise intensities between 50% and 75% of VO 2 max. A ...
Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...
Cardiovascular drift. Cardiovascular drift (CVD, CV drift) is the phenomenon where some cardiovascular responses begin a time-dependent change, or "drift", after around 5–10 minutes of exercise in a warm or neutral environment 32 °C (90 °F)+ without an increase in workload. [1][2] It is characterized by decreases in mean arterial pressure ...
The 3-2-1 rule. There are three things you should cut out before bed in order to achieve a better night’s sleep. Breus broke down what they are and when to quit them with these simple guidelines ...
Cardiorespiratory fitness (CRF) refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity. Scientists and researchers use CRF to assess the functional capacity of the respiratory and cardiovascular systems. These functions include ventilation, perfusion, gas exchange ...
2. max. vV̇O2max (velocity at maximal oxygen uptake), also known as maximal aerobic speed (MAS), is an intense running or swimming pace. This is the minimum speed for which the organism's maximal oxygen uptake (VO 2 max) is reached, after a few minutes of constantly maintaining this exercise intensity. At higher paces, any additional increase ...
