How would I analyze the data from a gender difference study of heart rate?
I'm investigating the effect of exercise on the heart rate of two groups, females and males, in order to see the differences in gender. They would perform 20 jumping jacks at the same pace, and their heart rates would be measured.
How would I analyse the data? Is this using percent changes? Or is it using a certain kind of test?

There are several things you should do to create this experiment.
First, you should get the heart rate of the females and males when they are at rest. This will give you a baseline. Also you should keep in mind that it would be good to have a random sample of men and women, in order to protect your study against unintended selectivity.
Second, you should have the two groups do their jumping jacks. After they are done, you should measure their heart rate. You probably want to do this several times to make sure that the measurement are good.
Finally, you would want to compare the heart rates in two different ways. Compare the heart rates at rest and after exercise within each group - female and male. Whose heart rate goes up more? Then compare the heart rates of the two groups. The first will give you insight on how exercise affects women and men. The second will offer an interesting comparison.
