ABSTRACT
The purpose of this lab is to describe the procedures for performing the Critical Velocity (CV) test on a running track. The CV test estimates three parameters of physical working capacity: 1–5 (1) the maximal running velocity that can be maintained for an extended period of time without fatigue, called the CV; (2) the total distance that can be run using only stored energy sources (creatine phosphate, glycogen, and oxygen bound to myoglobin) within the activated muscles, called the anaerobic running capacity (ARC); and (3) the time to exhaustion or time limit (TL) during continuous running at any velocity (V). The CV test uses linear mathematical modeling of the relationship between the total distance (TD) at different velocities and the corresponding TL values to estimate the CV, ARC, and TL simultaneously at any velocity (Figure 12.1).
