The Effects Of Exercise On Pulse Rate

Aim: To find out how exercise influences the body, by measuring changes in pulse rate and blood pressure.

Introduction

The sugar is divided in our tissue into Adenosine Tri-Phosphate (ATP). ATP provides energy for techniques such as muscle contraction (the process necessary for exercise). The sugar and oxygen necessary for respiration are carried to the skin cells through the blood stream. The heart muscles contract to pump the blood around the body to the cells, providing the substances necessary for respiration. When you exercise the muscle cells (which muscles are made of) need to deal more than regular, requiring more energy. To create more energy the cells need more air and sugar than they would usually receive. To be able to supply the heart and soul muscles deal faster. This increased rate of contraction escalates the blood circulation pressure, transporting the blood round the body faster. The increased rate of contraction can be assessed through pulse rate or taking blood pressure. Glucose gets into the blood stream through the digestive tract but air is absorbed in to the blood stream through the lungs. Air is taken in to the lungs and diffuses in to the bloodstream. The air is transported round the body to the cells in this manner. In order to prove that these are the ramifications of exercise on your body I will need to perform an experiment. I'll exercise for mixed intervals or for varied durations of distance and I'll record my amount of breaths and pulse rate for one minute after performing exercises. I'll also record my pulse rate and inhale rate at rest. This should establish that both increase after exercise. To choose an exercise and also to determine whether I will use distance or time I'll conduct an initial experiment.

Method

1. Use the metre guideline to measure a distance of 62 metres.

2. Gauge the pulse (at the neck of the guitar or the wrist) each and every minute and volume of breaths per minute.

3. Jog the 62 metres (1 period).

4. When you have finished running record your pulse rate and range of breaths for one minute.

5. Jog 2, 3, 4, 5, 6, 7, 8, 9 and 10 measures, documenting pulse and number of breaths each and every minute after each amount of jogging.

6. Duplicate each range of measures at least 3 (preferably 5 or even more) times.

Result

My results helped me choose an exercise to work with for my test. running and motorcycle were all too exhausting to keep up for long periods of time (they gave an exceptionally high pulse and breathing rate for just one minute of exercise). Step ups, sit-ups and vitality walking gave quite low results, meaning that they could give insignificant changes after brief cycles of exercise. Exercising provided a good mixture between your two therefore i made a decision to use running as my chosen exercise. After choosing exercising I needed to determine whether time or distance was appropriate for my last experiment. I jogged for 1-5 minutes and I jogged 62-310 metres (62 metres was the distance of a tennis games court I used as a measure of distance). After jogging I got my pulse rate and deep breathing rate for one minute each.

Discussion

The exercise would have to give clear results that could make a significant difference to blood circulation pressure and pulse rate, without offering too drastic a big change. In the event the change was too drastic it might be difficult to keep up the exercise for years or distance. I noted results for eight different exercises, doing each exercise for one minute before taking pulse rate for one minute and breath for one minute.

Conclusion

Overall the evidence obtained was quite accurate and reliable. I saved several results for each distance in order to obtain a reliable average and to ensure that the results weren't incorrect or excessive. The results weren't as accurate as they must have been, however. Two results, one for amount of blood circulation pressure and one for pulse were anomalous and needed to be redone. The measurements considered were accurate so far as they go, but variety of breaths per minute is ambiguous. The tidal volume (depth) of the breaths may vary over the minute these were being recorded, with breaths at the start of the minute being deeper than those at the end (because of the fact that less energy is needed just after a fitness than is necessary a short while following the exercise). The procedure was relatively exact and allowed lots of chance of repeats. The task might have been improved if measures with changed with a continuing circuit, as more energy is necessary for turning and you will need to slow down to turn. The main problem with the task was that there is no foolproof way of keeping the pace constant. This could perhaps have been rectified by using an electronic fitness treadmill. On an electric treadmill you set a speed as well as your pace must stay the same in any other case you run out of space to jog on. The evidence is stable enough to support my bottom line, although more research is needed to confirm it. The evidence is also reliable as an acceptable amount of repeats have been conducted. To provide firmer results, more repeats should be performed on the wider range; preferably using several person (I used only myself in this test). Two anomalous results were registered. The first was a pulse rate of 123 after having run 310 metres (the other results noted were 169, 171, 174 and 170). This anomaly was the result of losing count during the reading. The next anomaly was 40 breaths after jogging 620 metres (the other results were 57, 54, 59 and 52). This anomaly was due to accidentally stopping the matter before about a minute had approved.

Reflection

As is seen after exercise pulse rate and respiration rate increased. The pulse rate gone up quite quickly initially, before slowly levelling off. Respiration rate increased continuously and slowly began to level off. The reason for this increase is due to the energy necessary for exercise. When working the muscles agreement to make move. To be able to contract they need energy. They produce this energy through a process called aerobic respiration:

As is seen Glucose and Oxygen must produce energy that muscle skin cells need to deal. Glucose and oxygen are taken to the skin cells in the bloodstream. Glucose is taken into the blood stream through the digestive system. Oxygen is considered into the bloodstream through the lungs. When humans gasp (breath in) the oxygen that is inhaled diffuses (diffusion is the random movement of molecules from an area of high concentration to low attention) into the bloodstream. The air diffuses through the alveoli, which can be microscopic "bubbles" in the lung. A network of capillaries (tiny arteries) surrounds these alveoli and it is through these that oxygen enters the bloodstream. In the bloodstream there are red bloodstream cells. These cells contain chemical called haemoglobin, which appeals to oxygen. The air is absorbed in to the red blood skin cells and varieties a compound with the haemoglobin, called ox haemoglobin, the heart muscles agreement, forcing the bloodstream across the body. The air is transported across the body in the red blood cells; to where it is needed (it is necessary in all skin cells as they must all perform respiration to survive). When you exercise the muscle cells need to create more energy than usual, so they want more air and blood sugar than usual. To permit this to happen, your respiration rate must increase. You ingest more breaths as well as your tidal amount the depth of your breath increases, Muscles in between your ribs contact, moving up and out and your diaphragm (a sheet of muscle in the bottom of your chest cavity) contracts, moving down. This escalates the volume in your thorax (torso cavity), decreasing the pressure. Air rushes right down to equalise the pressure. When you exhale your intercostals muscles and diaphragm relax, moving back again to their original positions. The pressure is increased in your thorax so air rushes out to equalise the pressure. Your intercostals muscles and diaphragm agreement more quickly and written agreement more than they usually would, to permit a greater amount of deeper breaths. Sugar and air must still be transferred to the cells, however. To perform your center muscles contract quicker. This increases the blood circulation pressure, forcing it across the body faster. This can help transport the oxygen and blood sugar to the muscle cells quicker. Also, it makes sure that a great deal of blood vessels is circulating about the capillaries in the lungs, so that more oxygen can be ingested into the bloodstream.
