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 ...
The multi-stage fitness test is also part of most health-related fitness test batteries for children and adolescents, such as Eurofit, [3] Alpha-fit, [3] FitnessGram [4] [3] and ASSOFTB. [ 5 ] The multi-stage fitness test was first described by Luc Léger [ 6 ] with the original 1-minute protocol, which starts at a speed of 8.5 km/h, and ...
Running economy (RE) a complex, multifactorial concept that represents the sum of metabolic, cardiorespiratory, biomechanical and neuromuscular efficiency during running. [1]: 33 [2] [3] Oxygen consumption (VO 2) is the most commonly used method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects energy metabolism.
The type of oxygen sensor used in most underwater diving applications is the electro-galvanic oxygen sensor, a type of fuel cell, which is sometimes called an oxygen analyser or ppO 2 meter. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and trimix . [ 9 ]

The Clark oxygen electrode laid the basis for the first glucose biosensor (in fact the first biosensor of any type), invented by Clark and Lyons in 1962. [6] This sensor used a single Clark oxygen electrode coupled with a counter-electrode. As with the Clark electrode, a permselective membrane covers the Pt electrode.
The speed varied depending on the loop length up to 20 Mbit/s. [citation needed] In 2015, O2 Czech Republic (owned by PPF) was split into two companies: CETIN, which owns the fixed and mobile network, and the mobile operator, O2. [18] CETIN is offering its cable network not only to O2, but also to another ISPs.
