How does exercise affect heart rate?

Extracts from this document...

Introduction

How does exercise affect heart rate? Aim The aim of this experiment is to investigate how exercise affects heart rate. I am going to record my resting heart rate, then exercise for 30 seconds , then 1 minute and increase the period of exercise by 30 seconds until I am exercising for three minutes without stopping . I will does this twice and take an average Prediction I predict that my heart rate will increase as a result of exercise. I think that there will be a slight increase to begin with, but as the body has to work harder I think that the heart will then increase at a faster rate. ...read more.

I will keep the exercise, step ups, the same. To keep it a fair test I will rest between each period of exercise to let my heart rate to return to my resting heart rate. Apparatus Timer, step Method Collect apparatus Record resting heart rate for 1 minute (arm, neck, temple, chest) Exercise for 30 seconds and record your heart rate Rest until your heart rate is as it was at resting Repeat this for each period of exercise increasing it y 30 seconds each time until your exercising for 3 minutes Do this experiment 3 times to get an average Results Time minutes 1st pulse bpm 2nd pulse 3rd pulse Average pulse 0 60 64 64 63 0.5 ...read more.

Conclusion

you exercise for longer periods of time as your muscles need more energy to work longer Evaluation My results were quite accurate although there was one anomalous point which didn't quite follow the straight line pattern (circled on the graph and table) this may because I rested to long and didn't start again on time. Because this was only found out from my averages I couldn't repeat it although if I had more time I would have liked to. If I could improve this experiment I would use a more intense exercise like running on a treadmill as I think this would be more accurate as you can keep the intensity the exact same for each period of exercise ...read more.

  1. Investigate how the pulse changes during physical exercise.

    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.

  2. Personal Exercise Programme

    For example I will be undertaking a light jog with a full range of stretches. 1. Cool down reduces injury 2. Keeps capillaries open 3. gets rid of lactic acids 4. prevents muscle soreness 5. lowers levels of adrenaline 6.

  1. Discuss the physiological mechanisms underlyingthe benefits of exercise in diabetic individuals.

    Insulin stimulates the translocation of these vesicles by binding to the Insulin Receptor (IR), which leads to tyrosine phosphorylation of adapter proteins, including members of the Insulin-receptor substrate (IRS) family (Alexander et al. 2000). IRS-1 and IRS-2 act as docking proteins for PI 3-kinase which is a key signalling transducer in GLUT-4 translocation to the plasma membrane (Alexander et al.

  2. Investigating Human heart rate.

    I feel that it would be more appropriate counting for 10 seconds and not a whole minute because it would be easier to count and would be the pulse as close to the moment after exercise, or the resting period.

  1. Investigating the Short-Term Effects of Exercise on the Body.

    This was in order to pump blood around the body quicker, supplying oxygen to these cells. Overall, pulse rate and intensity of exercise are proportional. The greater the intensity of exercise, the higher the body pulse rate is - after exercise.

  2. Mechanics of Breathing and responses to exercise

    The graph above is the average group results for respiratory rate. The standard error is also show. It is much smaller for the after holding breath and after exercise compared to the standard error for the tidal volume results and the standard error appears to have remained the same for the control.

  1. Fatigue - affects on the body

    The absence of calcuim means that that the sliding filament theory cannot take place. During contraction calcuim ions bind to tropinin, causing exposure of the vross-bridge, allowing actin and myosin to attach. While lactic acid may play a role in fatigue its supposed role in muscle soreness has been disproved

  2. Conduct the Queens Step test (provided) for all 4 students. Record the resting heart ...

    After 5 minutes recovery time, her heart rate was 30 beats per min. This is not accurate as it is more than half of her resting heart rate at the start and does not correspond with her exercise routine at the present.
