1.3 BACKGROUND INFORMATION:
Cardiovascular system transports essential nutrients, gases, and hormones throughout the body. The heart, lungs, and blood arteries all work together to form the CVS. The heart is a pump that pumps blood around the body. Blood vessels serve as conduits that transport blood throughout the body. The lungs provide oxygen to the blood and eliminate carbon dioxide. The CVS is kept in balance by a multitude of sophisticated nerve and hormone systems that respond to the body's shifting oxygen and nutritional demands. Each heartbeat begins with an electrical signal created by the pacemaker, a component of the heart (the sinoatrial or SA node). This signal goes via the heart's nerves and causes the heart muscle to contract, causing blood toflow.The ‘pulse' of blood moving through the arteries may be felt in the wrist and neck. The resting heart rate of a healthy individual is normally between 60 and 100 beats per minute (Intensive Care NSW, 2021) The radial artery is the most typical location for a pulse check. Several fingers are inserted around the wrist joint on the artery. Because of the broad, sensitive surface accessible to detect the pulse wave, it is advisable to utilise more than one fingertip. The number and regularity of beats per minute, the intensity and strength of the beat, and the strain given by the artery to the finger are all noted as the pulse is examined. In most cases, the time between beats is the same length. (Oliver, Entman and Jacob, 2020)A healthy heart requires physical exercise such as skipping, which can also help avoid Coronary Heart Disease. Your heart is a muscle that becomes stronger with activity, just like any other muscle. Skipping is a good example of a frequent physical exercise that helps your heart get stronger. This implies you'll have more stamina and energy since it can pump more effectively. Increased activity, such as skipping or other aerobic activities, will boost your body's tissues' ability to take oxygen from your blood. This will aid in the maintenance of appropriate blood fat levels as well as the acceleration of your metabolism (skip-hop, n.d.) Jumping rope raises your heart rate and respiration in the same way as running does. If you jump rope for ten minutes every day, your body will adjust in ways that are advantageous to your cardiovascular health, including as decreasing blood pressure and slowing down your resting heart rate. Jumping rope improves cardiorespiratory fitness, which means your body becomes more effective at absorbing and using oxygen. Cardiorespiratory fitness has been related to better health and lifespan in studies. Improved cardiorespiratory fitness has been demonstrated to lower blood pressure, enhance insulin sensitivity, reduce inflammation, and minimise the risk of diabetes and other chronic diseases (Bottoms, 2020) Somewhere in report, purposes of experiment pulse rate, things of the heart. How the heart rate shows up in the pulse rate.
2.MATERIALS AND METHOD:
Gather all equipment that is necessary to conduct this experiment

  • Set up space to do experiment

Variables:
Exercise how the heart works Talk to you about that about how you look look up your research and then down here in your discussion this is how your results will likes to your knowledge of your heart thing and you'll probably have to look up a little bit more stuff because you've now got some numbers to work on that are specific and as I said here your results look like you're pretty fit sort of person because you can um you could say here or even at the beginning how what a high blood pressure means what a low blood pressure means but a high pulse rate means model low pulse rate means and so that when you get to discussing here um it says discuss the changes in your health parameter over time why did the exercise in your case change it what was the heart doing that made those numbers go up and then down again OK and that that after you done exercise you pulse rate rocketed up and then it calmed down again but not back to normal um and um why this might be the case why doesn't the body go straight back to normal when you stop why does it why is there that time lag boy if you start at 65 in five minutes it's like this but 10 minutes later it's not even it's barely halfway down again what why does it take so long to get back to normal for you half an hour was enough because in half an hour you were back up to be old virtually the same pulse rate you started with so your body had got back to normal within 1/2 an hour now I'll tell you that's pretty quick Olympic athletes who have done a long distance run if the sum of them can't run again for example the the two the two mile mile Sprint people have done the mile which is basically a mile sprinting they can take a whole day to get back to the pulse rate and hardware that they had before they started the race body just takes a long time to get back even for an elite athlete so why is that what else is happening in the body that means it your heart rates keeps going even though you stopped doing him exercise and get your heart still thinking that that you are what what is that they can just throw in a little bit of research on that this plenty it's not unusual why does the heart just keep going like that why is apt so high after exercise and so this would be part of your explanation explaining you that yes your bull your hypothesis obviously was going to be correct you exercising and pulse rate goes up but did it completely agree with it did it completely agree with when the answer was toilet didn't go back to normal becausr blah blah blah blah blah blah blah you see what I'm saying OK 'cause that that's what makes this exercise interesting so I mean I used to teach it the last time I thought it was was beginning of last year can't remember now but that was what throw most throws most people why didn't it go back to normal why is it so wonky the whole thing like my heart rate went down pretty quick would I have to say it's because I do training everyday BLOB like well I have to explain that it would be very good to say as part of your observation that um rather than you could say my suppose if you explained that it's yourself doing this not somebody else you could say that because this one explanation I want explanation for this change all all in any research you can say in in this in my experiment because I am a I am a fit person who trains regularly my heart rate returned to normal within half an hour for other other people may take a lot longer because fitness affects your heart in this way so and that's where you can talk about how you can try in the heart to to pump or not come depending on how it is your hearts are must your heart is a muscle muscles get used are efficient muscles that don't get used are inefficient that's just the way it is so big and so you can sort of you can put that in as an opposite part of your observation that having explained how the heart takes time to get back to normal and why and then you can burn your building that BIH cause I train regularly this my heart is an example of how hard can get back to normal quickly if it's in good and fit or something like that yeah perfectly reasonable it's a good thing to throw in when you're online too OK um I mean you can even put it in your conclusion you could ****** then your conclusion says address what you learned the I'm in the research question and you say my the fact that I am a big train regularly and am fit and my and my blood pressure went back back to my heart rate went down to normal so quickly supports my hypothesis which is blah blah you could just put a little little comment like that in where you actually you actually related your experience and your experiment and your personal observation do you hypothesis OK doesn't it doesn't have to be your life story something like a quick summary or something it just does something like that shows that you actually applied this too sorry no it's alright so it'll probably go again Asian but I've got a machine that I cheque my blood pressure and so on with each morning and that's it gives me a rate like you know 100 / 60 at 50 or something so you could you could just sort of explain how your heart rate works with blood pressure or something just the health president pulse measures about that body system and so that pulse and blood pressure are very closely tide up together and you might say that your machine measures blood pressure and pulse or not whichever you prefer and then you could say an average pulse would be for example for example you might get a hunter S in 100 / 50 at 70 or something I think is pretty over 220 / 6072 or something I think is the average of can't remember and explained that that's what these parameters are and then down here um here talk about the normal health range would be a blood pressure and pulse combination of something like such and such to so and so or resting pulse for an average female might be arresting pass from average male might be an exercise right and there might be some examples when you do your research there might be some typical exercises that are done and I'm sure there are that for example if you go to the doctor and they give you as a stress test on of treadmill or something they will have a set of pace and time which they can compare you with all of the other people who come in for example with your weight so and I can cheque it with the Aussies above or below what the average is full of people that have come in to do that stress test but there'd be no point in a doctor saying I would you do yours yours is test for five minutes and Joe bloggs coming in next they can do 7 minutes and or marries in a hurry she can do 2 minutes 'cause you can't workout what an average would be for that exercise so you might want to just throw find find something about averages here when you research it average for a healthy female average for healthy mile or something what what's the normal range OK OK and then you know about how to do a reference list and all that so looks like to me like you're pretty well sorted anything else in particular that you needed um looking at I think the mature mature mine issue is actually going to be being careful about apart from fixing up your details on your method but make sure you explain in your your app and your piece of equipment that you're using this background information using reliable references and routine health indicators you know this standard blood pressure don't forget there's gonna be difference from males to females all too young you'll have to say well if you're going to you can't put them all in there's lots so you can say for an average person in the 20 to 40 age group or mail through a male or a female or something yeah 'cause I'm only 19 as well OK well you have to make it in the in the for my mic for my turn into 30 then just so I could squeeze in there yeah sounds like average teenager 'cause there's a big difference in what you can do now at 19 compared to 13 for example I don't imagine when you were 13 you could do what you're doing now at 19 so we sort of say 18 to 30 so or whatever you could you pick a slot but you know what I'm saying you don't pick at the average 19 year old because that's too that's too specific yeah you just pick up average like like a range of ages like you said 18 to 30 Yep something like that yeah so this is what it is or what whatever whatever is given and if they only go from 20 to 30 don't worry about it haven't got the other birthday yet just do it and if you don't like it don't don't let that little snippet why are you um now some back here the effects of their child on here what are some of the things that I'm not quite sure 'cause I have I don't have this criterias but changed a little bit background into the effects of their chosen change on the chosen indicator why OK why outline the normal healthy range for the indicator and some background into the effects why does it go up you tell me why does the pulse rate go up when you start to exercise um I don't know how to explain it why does the body need the heart to work harder and the pulse rate to go up well what is what is the actual heart actually physically what exactly doing well it's producing more producing anything now what it's actually doing something what do you what is the function of the heart what is doing this what's it doing to to beat I don't know how is a pump pump pumping blood is pumping blood why is it does it need to pump faster when you're doing exercise what is it actually doing where is the blood going from the heart two places very important Lee what does blood carry that your body needs oxygen it does it carries oxygen so when your heart is pumping where does the blood go two places to your lungs yes it goes to your lungs to pick up oxygen and to dump what go to get rid of I don't know but I forgot the word for it when you breathe out what do you breathe out what guess um carbon dioxide it's right respiration produces carbon dioxide oxygen in carbon dioxide out if it didn't work like that we die yeah well the planet stops OK respiration remember you did respiration and photosynthesis OK So what happens is the the hardest pumping first up the blood that the used up blood from your body goes to the heart and gets shifted into the lungs in the lungs the carbon dioxide comes out and fresh oxygen goes in the carbon dioxide hot out in a with the oxygen out carbon dioxide rubbish OK so it goes for the having picked up a nice dose of oxygen that lovely fresh now bright red oxygenated blood then goes back to the heart and then the heart pumps where where does it go come on easy answer enter the what into the body body so so the heart the blood for them from the heart goes to the body carrying the oxygen and so why does it come faster when you need to pump faster when you are doing exercise exercising no you'd breathe more small what is your body using up very it's using up oxygen very very fast your muscles are chewing through the oxygen because in respiration remember to get your energy ATP to get your energy your oxygen links up with your carbohydrates and it produces ATP energy so you gotta be constantly pumping oxygen into your cells so they can be pumping out energy so you can keep exercising yeah so that's what's happening and as a result of all that they're producing a lot more carbon dioxide so you're breathing in more so you get more oxygen you're breathing in faster to get more oxygen at the same time your blood is coming through and dumping more carbon dioxide and it's going like 90 OK when you stop does your body suddenly stop like that like I've had a brick wall and everything goes back to normal no no it doesn't it takes time for all your cells to get back to normal balance and that's going to travel right through your body and your cells have been geared up to work fast and now they've got to be ungauged to slow down back to normal so they gonna take awhile to get rid of all that excess carbon dioxide that they've made and turn off all the enzymes that have been pushed into them to work faster and produce their proteins more quickly and to break up there carbohydrates more quickly so so it takes longer to get back to normal that making sense no no yeah it does it does yeah OK so now you've had a little extra little you've travelled through the body and now you're back to normal and so now you understand why even though you've stopped your body has to play catchup yeah OK fantastic, that in the background. Respiratory rate - pulse rate Please read what’s highlighted these are notes that were dictated from my teacher. Make sure to add what she says in discussion and conclusion. Read the read and add all the red in the discussion and conclusion use some academic sources to reference please. Any source that is referenced add to the reference list please.
