# Heart Rate Lab

## Research

We decided to set up our experiment by having two different exercises and exercisers. We did this because we wanted to see how it affected each person and which exercise was the most effective in raising your heart rate. We took our resting heart rate while sitting down and a few minutes after the exercises, we decided to do this because during our research its best to wait ten minutes and lie down and then test it but due to time restraints, we only waited a few minutes.

## Hypothesis

If the exercisers do the exercises, then the heart rate will increase, then after a minute of monitoring the heart rate, the rate will get slower.

## Independent/Dependent Variable

Independent- Sprints and stairs

Dependent- Heart rate

## Control

Resting heart rate, and where the pulse is taken.

## Constants

Meghan, Eduardo and time.

## Averages

Meghan-(gray)-24

Eduardo-(blue)-34

## Average of BPM

Meghan-(gray)-72.66 --> 73

Eduardo-(blue)-72.83 --> 73

## Average of Recovery Time

Meghan-(gray)-58.66 --> 59

Eduardo-(blue)-103

## Conclusion

Once the exercisers do their exercises, and wait one minutes, then their heart rate will have slowed down. As you can tell in the data when Meghan and Eduardo finished doing the exercise, Meghan and Eduardo's heart rates were fast, then after a minute became slower. For example after Eduardo did his sprints, the pulse was faster than it was after Eduardo waited a minute to take his pulse again. Whenever an exerciser does any exercise, specifically a few sprints or some stairs, the pulse will be faster than the normal heart rate. But after waiting one minute or a few minutes, the heart rate should go down to normal or almost normal.
