Demonstrating and Predicting Aerobic Power
Most students are familiar with or have some understanding of the concepts of aerobic and anaerobic respiration at the cellular level. During exercise, muscle contraction requires energy (ATP), which is supplied by both the aerobic and anaerobic metabolism of nutrients. Short bursts of high intensity exercise mainly utilize anaerobic energy sources, while exercise enduring longer than three to five minutes will utilize energy provided by aerobic metabolism. Students often have a difficult time being able to see an application of these concepts in human physiology. This lab activity will demonstrate anaerobic power in a physiologic way to which students may be able to relate.
