The devices used in the study, RS-400, were provided with the "OwnCal" software calculating energy expenditure from variables such as sex, age, body height, BM, maximum heart rate ([HR.sub.max]), maximum oxygen uptake
(V[O.sub.2max]), and a level of physical activity, and from heart rate monitored on an ongoing basis .
(2011) Validity of the 20 meter multi-stage shuttle run test for estimation of maximum oxygen uptake
in male university students.

, CWS = comfortable walking speed.
The maximum oxygen uptake
([VO.sub.2max]) value was accepted when the following criteria were met (15):
There is an increase in heart rate, cardiac output, and stroke volume, and a reduction in maximum oxygen uptake
which reduces exercise tolerance.
Direct measurement of maximum oxygen uptake
(V[O.sub.2] max) is recognized as the best single index of aerobic fitness .
For example, a single anchor method might involve assessing the change in maximum oxygen uptake
required for people to rate their health-related quality of life (the anchor) as much improved.
Participants were young (mean age, 27 years [SD, 3]), lean (mean body mass index, 24 kg/m2 [SD, 2]), and physically fit (mean maximum oxygen uptake
, 51 mL/kg of body weight per minute [SD, 8]).
The payoff from the 3-month intervention was significant reductions in waist circumference, diastolic blood pressure, body weight, fat mass, and LDL cholesterol, and increased aerobic capacity as measured by maximum oxygen uptake
, or [VO.sub.2] max, said Dr.
Eight of the 11 studies reported that aerobic exercise resulted in an approximately 14 percent improvement in cardiorespiratory fitness (as measured by the maximum oxygen uptake
test); this improvement coincided with improvements in cognitive capacity.
"You've got to get the oxygen a distance of about two metres from nostril into muscle.To get to maximum oxygen uptake
The V02 max test measures the maximum oxygen uptake
of the body and is considered a good way of assessing your fitness level.
