S10 Aerobic Exercise Physiology

In the Aerobic Exercise Physiology lesson, students record ECG and heart rate under a variety of conditions. Students see how the electrical activity of the heart and their heart rate change to meet changing metabolic demands. Students exercise to elevate heart rate.

• National Science Education Standards Correlation

Experimental Objectives

1. Measure changes in heart rate associated with a specified set of dynamic exercises.
2. Assess individual physical fitness by measuring elevated heart rate at the immediate end of a specific exercise period.
3. Assess individual physical fitness by measuring the time from the end of exercise to the return of resting heart rate.
4. Compare performance levels between groups, such as young women vs. young men, or persons with body weights of 75-150 lb. vs. persons with body weights of 151-250 lb.

Tasks Performed by the Student

• Record ECG and heart rate.
• Calculate personal maximum heart rate.
• Sit and relax.
• Exercise (e.g. running in place/jumping jacks) to elevate heart rate.
• Recover from exercise (sit and relax).
