Recovery rate after exercise

Possible sources of error:

• Might not be able to find the pulse right away after exercise, so it will increase the chance of data being incorrect.
• We measured the heart rate by counting, so it might not be reliable. Instead, we could have sued a proper machine, which will reduce the chance of human error, for example: a heart rate monitor.
• We measured our resting heart rate on a hot day, and our heart rate after soft and hard exercise during a cold day and after a cross-country race. The resting heart rate from the first day might differ from the one on the second day, because it might be slightly higher.
• During the two minutes of rest before we measured our resting heart rate, we might not be completely still, so it might have affected the results, which will be slightly higher.

 Interpretation:

• Her resting heart beat rate is 72 beats per minute.
• Her heart beat rate was 84 beats per minute after soft exercise and it took her 3 minutes to return back to resting heart rate. Whereas, my heart beat rate was 130 beats per minute after soft exercise and it took me 6 minutes to return back to my normal resting heart rate.
• Her heart beat rate was 144 beats per minute after hard exercise and it took her 5 minutes to return back to resting heart rate. Whereas, my heart beat rate was 170 beats per minute after hard exercise and it took me 6 minutes to return back to my normal resting heart rate.
• Rachael’s rate for soft exercise was:

• rate = (84-72)÷3
• rate = 4

• My rate for soft exercise was:

rate = (130-90)÷6

rate = 6.67

• This shows that my recovery rate is faster. But it took me longer to recover to resting heart rate as my heart rate after exercise was much higher than hers.
• Similar time were taken for both of us to return back to resting heart beat rate after hard exercise.
• Half the time of mine was needed for her to return back to resting heart beat rate after soft exercise.

Interpretation:

• His resting heart beat rate is 72 beats per minute.
• My resting heart bat rate is 18 beats higher.
• His heart was was  80 beats per minute after soft exercise and it took 2 minutes to return back to resting heart rate. Whereas, my heart rate was 130 beats per minute after soft exercise and it took me 6 minutes to return back to resting heart beat rate.
• Hanley’s rate for soft exercise was:

• rate = (80-76)÷2
• rate = 2

• My rate for soft exercise was:

• rate = (130-90)÷6
• rate = 6.67

• This shows that my recovery rate is faster. But it took me a longer time to recover to resting heart beat rate because my heart beat rate after exercise was much higher than his.
• His heart beat rate was 152 beats per minute after hard exercise and it took him 4 minutes to retun back to resting heart beat rate. Whereas, my heart beat rate was 170 beats per minute after hard exercise and it took me 6 minutes to return back to resting heart beat rate. The difference in heart beat rate after exercise was 18 beats per minute, which is the same as the difference in resting heart beat rate.

Comparison:

• In general, I have the highest resting heart beat rate with a difference of (all three of us) 18 beats per minute.
• It took my heart beat rate the longest to return back to resting heart rate after soft and hard exercise.
• Overall, I think that I am the most unfit.

Explanation:

• During exercise, we respire more and require more energy than we do at rest. Therefore, the heart pumps faster to get the oxygenated blood with oxygen and glucose to all the cells in the body, especially the muscles.
• The more you exercise, the higher you heart beat rate and the longer it takes for it to return back to resting heart beat rate.
• During exercise, your heart beats faster. Regular exercise is good for you because it exercises the heart muscle, making it stronger. Also, when the exercise is over, the heart rate returns to its normal resting heart rate more quickly if you are fit.
• We all have different resting heart rates depending on different mass, consuming different amounts of energy each day, how active they are, gender, growing or not and if they are pregnant.
