[Measurement of maximal oxygen uptake in a Chilean population sample]
1Laboratorio de Fisiología, Universidad Metropolitana de Ciencias de la Educación, Santiago de Chile.
Background:
Maximal oxygen uptake is considered by the International Biological Programme as the international standard of cardiorespiratory adequacy and physical condition.
Aim:
To measure maximal oxygen uptake in normal Chilean subjects, to establish normal reference values.
Subjects And Methods:
Maximal oxygen uptake was measured in 2,203 subjects (451 women) aged 7 to 66 years old, during maximal exercise in a cyclo-ergometer or treadmill. This sample included trained sportsmen.
Results:
Maximal oxygen uptake in men was 3.4 +/- 0.8 Vmin (range 1.1 to 5.6) or 55.2 +/- 9.2 ml/kg/min (range 23.8 to 83.2). In women, the figures were 2.55 +/- 0.55 l/min (range 0.87 to 3.82) or 47.5 +/- 8.0 ml/kg/min (range 20.8 to 76.3). These values decrease 0.65 ml/kg/min per year of age.
Conclusions:
These values can be useful as a normal reference for epidemiological, clinical or sportive purposes.
