Safety: I will have to make my investigation at a right time and place, I will be doing so by; * Safe floor (enough space for the activate, and flat surface). * Make sure that's its safe to do exercise e.g. wet, slippery, gravel not involved * Make sure I have not just eaten * Two - three to support you * Not to do more than your body can take * Make sure you have your medical thing with you e.g. a asthma pump * Make sure that you have water near you * Be aware of what your are doing e.g. ...read more.

Conclusion

So why is it beating faster? Because you are not inhaling enough oxygen, you are not inhaling enough oxygen as usual so your hart is beating faster because it not getting its normal amount so it bets faster so it can get the oxygen it need, but the more exercise you do the harder it is for you to inhale, your hart beats even faster because your inhaling less and less the more exercise you do, finally you cant do any more exercise. As soon as you finish you take In deep breaths to get the oxygen you lost you breath heavily and get a cramp, and need to drink water because you lost a lot during your exercise. METHOD: 1. I first got all the equipment needed for this investigation(bike machine, skipping rope, etc) 2. I then relaxed for 5 minutes and then measures my pulse rate 3. did my first exercise and did it a good paste (1 press up in 2 seconds). 4. I then recorded my pulse rate for 15 seconds 5. relaxed for 1 minute and measured my pulse rate again for 15 minute till my pulse rate became at its normal speed. 6. I recorded it and repeated it another three times and made a average table 7. I then drew a good graph from my average table. RESULTS: Here are my results For each exercise I have repeated it 3 times. And done a average table to make my results clearer I have also drawn graphs for each exercise ABDULLAH ELGAYAR HOW FIT ARE YOU? ...read more.
