Fighting fit

Investigate your recovery after exercise
Q - How long does your pulse take to return to normal?

1. Draw out a results table: 2. Measure your pulse whilst resting and relaxed - record your resting pulse rate (bpm) 3. Decide on an activity, e.g. running on the spot, star jumps 4. Carry out your activity as intensely as you can for two minutes (discuss whether this is long enough and change if needed) 5. As soon as you stop the activity measure and record your pulse rate (bpm) 6. Repeatedly measure and record your pulse rate (bpm) every minute until either 10 minutes has elapsed or your pulse rate has returned to the resting rate you measured at the start. 7. Plot the results. Include a line on your graph to indicate your resting pulse rate. Use the graphing guidelines to make your graph an effective one. 8. Analysis and explanation, copy out and answer the questions: a. why your heart rate increased during exercise. b. compare your results with two friends in the class. Using the data from the experiment write a couple of sentences to explain who is the fittest and why.
