As you can see, this is my grafic about the beats I had when I was doing these three activities;
When I was doing the continuous running method, my beat was being regulated or sometimes going down during the whole test.
When I was playing handball, my beat started in a lower than when I finished the activity.
When I was doing the interval running method, I started the first lap slowly, as in the third one, so I get a lower beat than in the second lap, because I started quickly, as in the forth one.
