Stage 1 of aerobic energy is Aerobic Glycolysis.

Glycolysis breaks down Glucogen which produces 2 molecules of ATP and lactic acid the ATP is used to keep that system working the ATP system lasts for 10 seconds. The lactic acid system lasts between 40-60 seconds and when this runs out your body will start to train much slower than before for example.

When you are doing press ups you can go at a really fast and powerful pace for 10 seconds which is the use of the ATP/PC system after this you will start too slow down and pain will start to kick in due to your muscles burning, this is because of the build up of lactic acid. The next stage of this is called the Kreb cycle.
The Kreb cycle is where everything going on reacts and then creates 2 ATP molecules, Carbon Dioxide is also created aswell as hydrogen.

The third step of the energy system is called the electric transport chain during this process the hydrogen that is created reacts with the oxygen that is created and creates 34 ATP molecules.

Long term effects of the Respiratory, Musculoskeletal and Cardiovascular system.

 There will be an increased blood flow around our veins and arteries which is important to feed our muscles with oxygen rich blood. This is done by a elevated heart rate, our heart rate will increase.the faster and harder that we work. Although the longer we work and exercise our heart it gets bigger which makes it stronger and more efficient, This means our heart rate will decrease allowing us to work at a high intensity for a long period of time. When you exercise little cracks form in the bones, when they are being healed bone cells migrate to the stressed part of the bone laying down more bone which causes the bone to be stronger and more durable.

The long-term effects of exercise on the respiratory system are helping the lungs to become healthier and to produce a greater number of alveoli, and increasing the vital capacity and tidal volume of the lungs. Your respiratory muscles increase in strength . This will cause you to be able do excersize forr a longer period of time.


 The long term effects of cardiovascular are that you will have a lower resting heart rate and you will return to that quicker after stopping exercise. The Existing capillaries also open wider. Blood volume increases. The Body produces a greater number of red blood cells in order to keep  the muscles supplied with oxygen during heavy exercise.

I did a certain amount of excesize over a 2 week period i then saw how i felt after these 2 weeks and started to see changes happen. At the start of the 2 weeks i would go for a run and have to stop regulary for breath because my body wasnt used to the distance i was running. However i quickly felt an increase in my fitness at the start my muscles would tense up afterwards but after a week they felt pretty much fine. I no longer had to stop for breath because my diagphram had gotten much stronger. My heart also got used to it and started to pump the blood round accordingly to how much oxygen i needed.


Aerobic:
Long Distance Running: When long distance running for example a marathon you will burn about 2,600 calories you burn more in this excersize than the others because you are running 26 miles this is more than any of the other sports.

Swimming: In a 2 mile swim you burn about 1500 calories this would be less if were a 2 mile run but because of the resistance given againt you when you swim. alot more stamina is required to get through the resistance of the water.

Anerobic: 100m Sprint: A lot less calories are burnt when doing 100m sprint due to the fact that you are only using the energy from your atp-pc system which means the event will only last about 10 seconds long each time which means you oly burn about 6 calories at each sprint.

Javelin: Javelin is another explosive sport that only uses the atp-pc system which means you are not going to burn as many calories as swimming or a marathon. when you do javelin you can burn about 365 calories in an hour because for that 4 -5 seconds of doing it it can be quite demanding after a while.

Lactic Acid

Lactic Acid Builds up in your muscles between 40-60 seconds of exercise which means you will no longer be able to train at the same pace.Glycogen is stored in our muscles. Glycolysis takes place which breaks down glycogen. This releases molecules which enables atp-pc system to keep being produced.
This would not occur in these sports.
100 metres
Hammer

and most field events.
This would occur in.
Tennis. Serve and Volley

400 metres



We are concentrating on Anaerobic Glycolysis.

ATP-PC System

The ATP-PC system is an energy system in the body that releases a short burst of optimum energy for 10 seconds, the ATP-PC system breaks down after the 10 seconds. When the energy breaks some of it is used to reform the atp system whereas some of it is used to give you energy. Here are some sports that use this are:
100 meters
Shot-put
Discuss.
Javelin.
Hammer.

The Musculoskeletal System

In our lesson we learned about what happens to our muscles and joints when we exercise. We also did a sit and reach test before and after activity to see what effect exercise would have on our muscles. When we are exercising our muscles are expanding and retracting, as we build up our muscles, our muscles will tear and grow and repair themselves to be stronger, which is why our muscles grow. The reason why our muscles hurt is because of lactic acid build up, This is why we have to stretch before we exercise, this releases as much lactic acid as possible which stops our muscles from hurting because it doesn't build up.Muscles also work in pairs to provide a balance, a sense of stability and movement in the areas in which they work. Also, because there is two sides of the body, the muscles in most cases, are opposite one another. Joints: Joints that are not directly joined, are lubricated by a solution called Synovial Fluid that is produced by the synovial membranes. This fluid lowers the friction between the articular surfaces and is kept within an articular capsule, binding the joint with its taut tissue. This synovial fluid in our joints acts as a shock absorber and reduces friction when we are exercising. My results before exercise on the sit and reach test was 31 and after exercise 36, this shows that as heat gets to your muscles and your muscles start to expand and retract intensely, your muscles become more flexible which helps you perform better during exercise.     

Links

There are links with everything that happens around the body. For example if your heart rate increases your breathing rate will have to increase as well. This happens because my arteries constrict and the blood pumps around my body quicker which is giving my muscles more oxygen. if you exercise for a long period of time your body will start to react faster which will improve how much you can exercise.  

Cardiovascular Results

We also calculated our Cardiovascular results. We ran round the pitch for 10 mins and recorded our heart rate Before,During and After. My result before was 96 BPM, During 108 And after 144. We did this by taking our heart rate for 10 secs and then X by 6.  The image below shows how blood pressure increases.
