Lab #6 prediction and direct determination of maximal oxygen. Student learning objectives: explain how to administer an incremental aerobic exercise test to maximum, describe the heart rate, ventilation rate and oxygen consumption responses during an incremental aerobic exercise test to maximum. Metabolic cart or system including mouthpiece and nose clip. This lab will expose students to indirect (estimated) and direct measurements of oxygen consumption. For demonstrative purposes, two students will complete a maximal oxygen consumption test on a treadmill. All students will participate in the harvard step test. Procedures: heart rate measurement, palpation technique: after locating the proper spot, count the number of beats for a predetermined length of time (use a stopwatch if necessary), use tips of index and middle finger. Do not use your thumb (why: place fingers over approximate location of radial artery. i. Radial artery: located thumb side on wrist, usually in the little. Fill in table 1 below: convert data to beats per minute.
