Delivering What Muscles Need

There was supposed to be a graph but I couldn't get it.

1. Which activities increased your heart rate the most?
2. Which activities increased your heart rate the least?
3. Was the order in which you ranked the activities accurate? (It's good to be wrong!) Explain.
4. What changes did you notice about your heart rate as you became more active?
5. Why do you think your heart rate changed when you were more active? What inference can you make?

1.The jumping jacks increased my heart rate the most probably because I'm moving my arms and legs at the same time. 


2. Sitting down increased my heart the least because I didn't have to move unless you count things like breathing.

3. I did not predict correctly I assumed that sprinting in place would get my heart rate up the most without a doubt.

4. My heart rate increased as I became more active.

5. I think my heart rate increased when I became more active because I needed more blood and nutrients so my heart pumped more blood and it pumped it faster than usual.
