How Do Different Activities Affect Your Heart Rate?
by Rachel A.
4th Grade - 1st Place

Hypothesis: Activities like reading and music will lower your heart rate. Activities like sit-ups, walking, jump roping, and running will increase your heart rate. Jump roping and running will make a person hit their taget heart rate.

Conclusion: For non-exercising activities, depending on the person, music either slightly increased the heart rate over their resting heart rate or slightly decreased under the resting heart rate. The change was generally between 6 and 10 percent. Reading stayed slightly above a person's resting heart rate but never went above a person's minimum target heart rate. Reading increased or decreased the heart rate
by 10 percent.

The anaerobic exercise I chose was sit-ups. In general people's heart rates stayed between the minimum and maximum heart rate. Heart rates increased by 12 to 40 percent. The aerobic exercises I chose were walking, jump roping, and running. Walking heart rate stayed between the minimum and maximum target heart rate. The percent of heart rate increase was 10 to 37 percent. Jump roping increased a person's heart rate by 63 to 149 percent. Most people hit their maximum heart rate. The rest of the people at least hit their maximum target heart rate. Running increased people's rate by 96 to 215 percent. People either hit their maximum heart rate or were just below their maximum target heart rate.

In conclusion, of the four people that participated two had heart rates that were highest when they were
running, the other two when they were jump roping. Jump roping increased heart rates the fastest.
Therefore, aerobic exercise increased the heart rate the most, and nonexercise had little effect on heart rate.
