Fitness Test

A large red and blue cube frame that has blue and orange banners running from top to bottom with different information on each. In front on the grey carpet is a long checkerplate steel box.

Your heart beats faster during and directly after exercise.

How it works

After stepping up and down on a block, measure your post-exercise heart rate.

Things to try or ask around the exhibit

Step up onto and down off the block for three minutes (each step should take about one second). After three minutes, count the number of pulses (at your throat or wrist) in fifteen seconds. Read your fitness level on the chart.

Background

Your heart pumps blood rich in oxygen from your lungs to your muscles. During exercise, muscles need more oxygen. So, you breathe quickly to take in more oxygen and your heart beats faster to deliver more oxygen to your muscles.

Finding the science in your world

Fit, healthy hearts pump blood more efficiently and have lower pulse or pumping rates during and after exercise.
