Chapter 4, Problem 3O
Summary Introduction
To describe: The graphical changes in oxygen uptake and lactate during an incremental (graded) exercise test.
Introduction: The maximal ability for the heart, lungs, and blood to transport oxygen to other tissues in the body and utilize it to transform energy is called maximal oxygen uptake or VO2 max. An increase in oxygen consumption and uptake usually results in (VO2max).
Summary Introduction
To identify: The lactate threshold and maximal oxygen uptake (VO2 max).
