Will walking create the same cardiac response as running? Physical activity is associated with numerous health benefits, even modest levels of physical activity (Janssen & Leblanc, 2010; Strong et al., 2005). However, many students remain largely inactive. This module is designed to promote student-specific physical activity as a health promotion strategy by introducing the concepts of vital signs and target heart rate training. Ideally, students will discover an enjoyable type of exercise and/or learn how to self-assess their cardiovascular responses (i.e. vital signs) to exercise to most effectively train.
Students learn: 1) How to measure basic vital signs, 2) How to calculate their own target heart rate, 3) To design their own workout plans, and 3) How exercise duration and intesnsity affect performance.
This module helps students learn about the mammalian dive response. Students simulate a dive by submerging their faces in cold water for 30 seconds. They measure heart rate and body temperature before and after the “dive”. Students learn how the human body responds to stress (cold water) and they convey their findings using bar graphs and a final lab report.
