human’s low recovery rate and
their physical condition.

correlation to the excellence of their physical condition.

INTRODUCTION
A heart rate is crucial to understanding the physical health of ones heart. One can determine
their heart rate by measuring the amount of beats or pulses they feel per minute. Exercise has
been known to decrease one’s heart rate, and make the heart much stronger to pumping blood
around the body. The heart does not have to pump as hard or as often, to circulate the blood
around the body, because it is so strong. In this experiment, a test was done to determine the
heart rates of students ranging in age 18-20, based on their activity levels. Their heart rates
were recorded at various times after they did a 3 minute step exercise. The recovery rate of an
active human heart, should take the least amount of time to go back to a normal resting heart
rate. If a heart if unhealthy, there would be a longer time for the heart to come back to recover.
HYPOTHESIS
If low recovery rate after exercise correlates with an individual’s better physical condition.
MATERIALS
This experiment requires an 8-inch high chair, stool, stepper, or other object to stand up
completely on, and a timer/watch.
PROCEDURE
In this experiment, the radial pulse is measured for all of the collected heart rate data. The
radial pulse is located underneath the wrist, below the thumb.
To measure a resting heart rate, place your index and middle finger on the radial pulse and
count the amount of pulses for 30 seconds. Multiple by 2 to calculate the beats per minute.
Repeat twice for a total of 3 resting heart rates.
Now, the heart rate will be measured post workout. First, locate a set of stairs, or something to
step up on. Next, step on the higher surface with one foot, then followed by the other. To go
down, place one foot down, then the other. Maintain this pattern for a consistent pace, with a
steady 4-beat cycle. Do this pattern for a total of 3 minutes
Immediately after the 3 minutes of exercise, check the pulse for 30 seconds, and count the total
