# Recovery rate after exercise

Extracts from this document...

Introduction

Biology Assessment Skill 2 & 3: How quickly does your heart rate recover after exercise? My results: Table showing resting heart rate: Time (min) Number of heart beats (per 30 sec) Number of heart beats (per min) 1 47 95 2 45 90 3 43 86 Average 45 90 Table showing heart beat rate after soft exercise: Time (min) Number of heart beats (per 30 sec) Number of heart beats (per min) 1 65 130 2 59 118 3 52 104 4 47 94 5 44 88 6 45 90 Table showing heart beat rate after hard exercise: Time (min) Number of heart beats (per 30 sec) Number of heart beats (per min) 1 85 170 2 74 148 3 56 112 4 51 102 5 46 92 6 45 90 Interpretations of my results from graph: � The gradient of the line from hard exercise is steeper than that of soft exercise which means it recovered at a faster rate after hard exercise. The heart rate dropped by 30 beats per minute after hard exercise, whereas, it dropped by 18 beats per minute after soft exercise. � As time increases, it started to level out and reach the resting heart beat rate. ...read more.

Middle

Number of heart beats (per min) 1 72 144 2 65 130 3 47 94 4 38 76 5 36 72 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. ...read more.

Conclusion

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. ...read more.

1. ## Investigating the effect of exercise on the heart rate and recovery time.

3 star(s)

The web site ''www.smm.org/heart/lesons/lesson1.htm'' says that '' with exercise or physical activity, the heart rate increases to supply the muscles with more oxygen to produce extra energy. The heart can beat up to 200 times per minute with extreme exercise.

2. ## How Exercise Affects Your Heart Rate and Recovery Time

Units to measure in are beats per minute. Controls: * Take resting heart rate after 5 minutes sitting down without talking and moving as less as possible. * The time measuring your heart rate before and after exercise. For the before exercise reading I will take it over 60 seconds so that I get a more accurate reading over a longer period of time.

that the chemical reactions generate. They need to get rid of heat. Just like an electric motor, a working muscle generates heat that it needs to get rid of. In order to continue exercising, muscles must continuously make ATP. To make this happen, the body must supply oxygen to the muscles and get rid of the waste products and heat.
