Document Summary

Critical power (cp): represents the threshold of aerobic function - the highest sustainable work rate for which pulmonary. If you work above cp, you will fatigue rapidly vo2 will increase until vo2max/fatigue. If you work below cp, should be able to work for a longer period of time achieve a ss. 3 minute all out test: protocol used to estimate cp and w"- like wingate test but lasts for. Multi-step constant load test: cp is assumed to be y-intercept , w" is assumed to be the slope, draw a regression line. Graph: plot po against inverse of exercise duration- hyperbolic relationship becomes linear: po = w"(1/tlim) + cp. If you know cp and po and w", can predict how long person will last at a po y = mx+b. Relationship between cp in 1 test vs. multi test relationship is good- can predict cp accurately with a single 3 min test.
