There were some boats and barges astrand
in the mud, and these enabled us to come within a few yards of her without being seen.
fh = Heart rate in 5th minute during the Astrand

Portanto, a relacao linear entre o V[O.sub.2] e a frequencia cardiaca (FC), tem sido utilizada para estimar o consumo de oxigenio e o gasto energetico em jogadores (Astrand
e colaboradores, 2003).

A capacidade aerobia maxima ([VO.sub.2] max.), tambem denominada de consumo maximo de oxigenio, e aceita como a medida normativa de aptidao cardiorrespiratoria, sendo considerada o padrao-ouro entre todos os indices (Astrand
e Rodhal, 1987).
In addition, based on the well-known linear relationship between heart rate (HR) and V[O.sub.2], alternative indirect approaches for the V[O.sub.2] estimate and the subsequent estimate of EE have been developed (Astrand
et al., 2003).

The PCI was founded on the principle that HR and walking speed are linearly related to V[O.sub.2] at the submaximal levels of exercise (Astrand
 compared cardiopulmonary responses between four widely used treadmill testing protocols in 51 men (22 active, 29 sedentary): Balke , Bruce , Ellestad , and modified Astrand
