Features of the
Cardiovascular System
1. Read the “ Pulse-Rate Method ” in section 8.3 Heartbeat of your Lab Manual .
On at least two different mornings, take your resting pulse rate , before you get out of bed in the morning , and
before you engage in any activity or are disturbed. Record your daily resting heart rate and the average.
Day 1: Day 2: Average Resting Pulse Rate = beats per minute
2. Computation of your target heart rate.
In order to improve and maintain the health of your cardiovascular system (i.e., to increase your stamina and to
reduce the risks of heart disease, strokes, diabetes, and impaired circulation), it is generally recommended that you
engage in aerobic exercise for at least twenty minutes, 3–4 times per week. During these exercise sessions, you
should sustain a target heart rate that takes into account your age and the current condition of your heart. [Consult
your physician before starting any radically new exercise regime!]
