In order for my experiment to be fair and gain accurate results I carried out two or three more times so that to see if there have been any changes to the results. I also consider the following points as I thought they would also make a huge difference. Such as I made sure that it was done accurately, not be under the time limit or over. Do not let the person stop skipping in the middle of the exercise because it will make an impact in the results.
I needed to ask some questions for my volunteer to fill in before we began our experiment. By doing this it enabled me to know my volunteer health conditions. This made me aware if my volunteer fitness level and medical conditions were in a good state because the questions are basically to check if my volunteer is healthy enough to be able to carry this task successfully.
Below is a questionnaire:
Questions :
What is the gender? male/ female
what is your age?
What is your height?
What is your weight?
Do you have breakfast in the morning everyday?
What is your fitness level/exercise?
How many days do you exercise in a week?
Do you eat fruits and vegetables? If yes how many proportions a day?
Do you smoke?
Do you drink alcohol?
Do you have any health problems e.g. diabetes, obese etc. If any please specify.
Results
Analysis
From the graph it shows that as the length of the exercise increases the pulse rate raises which then cause the heart rate to increase and taking time to return back to its normal heart rate. The highest pulse rate that is increase occurs in the third series of exercise (150 sec).
I also think that when the length of the exercise increase, the number of heart beats per minute will rise. The number of beats per minute will rise steadily because the amount of exercise will gradually increase causing the heart to beat faster. The heart rate raise during exercise because the respiration in the muscle increase so the level of carbon dioxide in the blood raises.
I believe that I have a positive conclusion because I repeated my results two to three times in order to take an average that would provide me with more reliable results. Which it did as my results were similar. However, if I were given to do the experiment again I would try my best to not stop skipping in the middle of the exercise. Also the more I repeated the exercise I became tired and as a result this may have affected the results as well.
I also believe that if I had more participations then it would have been better for me because then I would have a wider range of people and that could mean that I could have improved my experiment by comparing the differences between the participations results.
Health and Safety consideration
- Adjustment of the rope according to your height is very important.
- The place should be clean with lots of spaced provided e.g. gym, park.
- Shorten the rope so handlers reach their armpits.
- The participant should not skip if they ate heavy meals or lunch
- The participant should not continue skipping if they feel unconscious
- It is recommended to wear athletic shoes for pleasure rope skipping
I also believe that the person should make sure that they tie their shoe lace tightly so that it will be impossible for them to trip or fall down. I also think that skipping should take place in hard floors or on a flat surface by this it will help prevent injury.
Overall I am quite pleased with how I have carried out my experiment successfully because I think I was accurate enough. I have learned quite a lot of information about the effect on the heart rate while doing exercise.
