Cardiovascular test and Blood test

Cardiovascular includes-
heart,viens,arteries
pulse
blood presure

Cardiovascular test
Firstly i found my resting heart rate  - i did this by resting for two minets Then after taking my pulse for 10 secs and then timing the result by 6
My test was a 30meter relay race up and back-twice- 
Straight after i took my PuLes rate again for 10 secs again and times the result by 6 
My heart rate was alot faster after my exercise because my heart had to pump more blood around my body quicker delivering more oxygen to the muscles that require it. 

Blood presure; when your heart beats, it pumps blood round your body to give it the energy and oxygen it needs. As the blood moves, it pushes against the sides of the blood vessels. The strength of this pushing is your blood pressure. If your blood pressure is too high, it puts extra strain on your arteries (and your heart) this can cause heart attacks and strokes

my blood pressure before i exercised was _
And after i exercised it was _
The blood pressure increased beacause the vessles pump the blood around the body to deliver oxygen to the muscles that require them therfore our heart rate will increase too this is because every time our heart pumps its pumping blood around your body so the faster contracts together the higher your heart rate will be 


average blood pressure for an 15 year old 125/79
My resting blood pressure was 136/46 i have too much blood coming into the heart and not much coming out however this isnt a fair test because i havent done these so i was a bit nervous and this could affect the test because when you panic or get angry your body gives you a adrelanin rush which makes the blood pump faster its also known as fight,flight and fright its a natural instinct every human anamal e.c.t has            

Long terms affect of exercise on the heart
your heart beats will eventually decrease after exercise when consistantly done over a period of time. Beacuse your heart is a muscle consequently it will build and get stronger so it wont take as much beats to pump blood around the body

  1. Well done, excellent work on the cardiovascular system, good detailed account of what you tested and your results. This goes towards evidence for P2 and M2
    This also provides evidence for P1,M1 as you explain the changes.
