How Fit Are You
Planning:
I will do my exercise and recordings in this way:
- Make sure its fair and safe
- Measure my pulse while relaxed for 15 sec (and then *by 4 to make 1 minute)
- I will do my exercise, and as soon as I have finished record my pulse for 15sec
- Relax for 1 minute and then record it for 15 sec again
- And keep on recording my pulse till my hart has recovered and is at its normal speed.
e.g. this graph shows the increase and decrease in my pulse rate before, during, and after exercise.
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. if cycling fast make sure you have enough space and its safe
Fair tests;
I have to make sure that my results come out right to do so I will:
- measure my pulse before exercise.
- I will measure it at the same position e.g. sitting or standing
- I will repeat the same exercise three times.
- I will have five minutes between each exercise even though my pulse rate will have recovered.
- I will do each exercise for two minutes and do the same amount e.g. 50 press ups in two minutes.
- I will always use the same machines, place, and the same person to stop the stop watch.
Things which made my results not fair :
- Me and my group will do our exercise right after lunch break where we have been playing football and our pulse may not have recovered, so it will take longer to recover when it shouldn’t.
- Have just eaten and may not be able to do as much as usual
ALL THESE PROBLEMS MAY RESULT IN UNRLIBLE RESULTS
Prediction:
I predict that when I do my exercise my body temperature will increase and then will be detected by a part of the brain called the hypothalamus. Messages are sent to the sweat glands telling them to secrete sweat because the body temperature has risen. When the sweat evaporates it take heat from the skin, and the heat is lost to the air and you cool down.
When I do my exercise my muscles will need more energy so tissues and respiration has to go faster. my muscles need more oxygen and produce more carbon dioxide when they respire. And if my body does not work fast enough my muscles will start to feel pain because the is not enough oxygen in my muscles which mean that I am not inhaling enough oxygen and my body is having a hard time, for gaseous exchange. This is called Anaerobic exercise. Lactic will then be produced and very soon after I will have a cramp and will stop.
I also think that my pulse rate will increase on the amount of exercise for e.g. if I am doing bike riding and is traveling at a high speed my pulse will increase and my hart will be beating at a high speed.
Here is the equation for respiration:
Glucose + Oxygen = = = = = = = > Carbon Dioxide + Water +Energy.
Anaerobic respiration :
Anaerobic respiration occurs when oxygen is not available. Anaerobic respiration in muscles produce lactic acid which is toxic and can cause cramps. In yeast, anaerobic produces alcohol.
Glucose = = = = = = > Lactic acid + Water +Energy – humans
Glucose = = = = = = > Alcohol + Carbon Dioxide + energy – in yeast

INTRODUCTION:
Aim- Investigate how the pulse changes during physical exercise.
I have chosen to do the following exercise, I will measure my pulse rate before and after the exercise I will also note down how I feel during the exercise e.g. pain in muscles because of shortage of oxygen in muscles.
- steps
- jumping
- running on spot
- bike riding
- press ups
- skipping
I will make sure that my experiment will be fair and safe before doing it.
Analysing:
During this investigation I have spotted what I have said in my prediction and the research I have looked up.
Patterns in my results:
- If I do the same exercise my hart rate will increase but gradually go back to its normal rate.
- If I do a exercise where I do as much as possible for two min my hart rate will go very high but go back to its normal rate fast but still takes time.( but depends if you are fit or not fit).
- My repeats are always very similar, and if not it is because I have not fully recovered from the exercise before.
EVALUATION:
I have managed to finish this investigation very well I have done my practical work have written my results, I did have a result table which was not expected my hart rate was not recovered and back to its normal paste so it took longer to recover then usual. I repeated my exercise many times have drawn graphs which draws me to my firm Evaluation:
Evaluation:
You pulse is the beat of your hart rate if you hart rate is fast so will your pulse, when you do exercise your pulse becomes faster than usual your hart is pumping blood around and taking in deoxygenated blood it then goes to your lungs to get oxygen and is then taken to your organs and muscles your using.
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:
- I first got all the equipment needed for this investigation(bike machine, skipping rope, etc)
- I then relaxed for 5 minutes and then measures my pulse rate
- did my first exercise and did it a good paste (1 press up in 2 seconds).
- I then recorded my pulse rate for 15 seconds
- relaxed for 1 minute and measured my pulse rate again for 15 minute till my pulse rate became at its normal speed.
- I recorded it and repeated it another three times and made a average table
- 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
