Take your resting pulse rate (for 15 seconds).
Average the three resting rate trials and multiply the average by four to determine resting heart rate per minute.
Conduct the exercise and pulse-measuring portion of the activity.
Do the exercise and plot the results using excel, SPSS or by hand.
Scenario shift: Test for muscle fatigue by opening and closing a clothespin for 20 seconds. Then rest for a few seconds and do another 20-second-long set. Record how long it takes before muscle fatigue sets in.
Discussion
Answer 3 of the following questions:
What are some of the factors that influence resting pulse rate? Why might an athlete have a lower pulse rate than a person who does not exercise regularly?
In the “Recovery Time” graph, describe the changes that occurred to your heartbeat in minutes 1–7. Use specific numbers from the data table in your response.
If you compared the graph of an extremely fit athlete with the graph of a sedentary 50-year-old individual, would you expect them to be alike or different? Explain your reasoning.
What effect could a longer pulse recovery period have on a person’s ability to perform certain activities? What effect could a shorter pulse recovery period have?
What might a person do to improve his or her recovery period?
