Aerobic glycolysis
The conversion of glucose to lactate in the presence of oxygen has been termed aerobic glycolysis.
2atp are produced from aerobic glycolysis.
2atp are produced from aerobic glycolysis.
kreb cycle

the kreb cycle is chemical reachtion that produces carbon dioxide and Adenosine triphosphate.

Electron transport chain
stage 3
when you breath you can see the steam on a cold day and that is the co2 you are seeing.
34 atp are produced from electron transport chain.

ATP System
After 10 seconds of exercise your atp systyem run out and it will make it harder to exercise and you will have to depend on another system. The glucogen is stored in the muscles like sugar and it restores back your atp system so that you can use it for another 10 seconds and this is called glycolysis. Latic acid build up while you are exercising and that will make you have 40 to 60 seconds of exercise left.
Atp brakes down to make adp and releases energy into our muscles.
lacitc acid system
lactic acid system is what make your muscles hurt when you exercise and it take place in the muscles more stores of glycogen than pc so lasts longer about 14-15 seconds and no o2 needed so no delay will not happen. It burns you and slows you down and only 5 per cent of the number of ATPs that are produced by the aerobic system, yet more than the ATP/PC system. The lactic acid system is an important energy system because it provides a very quick supply of ATP for intense, short bursts of activity. this are a few sport that use this system is 100m sprint and weight lifting and long jump

long term effects of exercise
Regular exercise results in adaptations to the circulatory, respiratory and muscular systems in order to help them perform better under additional stress. Here are the changes which must take place within the muscles, respiratory system and circulatory system.so the more you exercise the stronger and thicker your heart get and your heart will be able to do four pump in one and that mean that your heart rate will decrease.
when you exercise your breating rate will go down because your lungs can hold more oxygen into your heart so then your heart beats faster and thats why your heart rate goes up and down. the number of red blood cells increases, improving the bodies ability to transport Oxygen to the muscles. The cardiac muscle surrounding the heart hypertrophies, resulting in thicker, stronger walls and therefore increases in heart volumes. The more blood pumped around the body per minute, the faster Oxygen is delivered to the working muscles. the longer you train your mucsle round your heart get stronger to pump more in one pump and your heart rate will decrease. if you train for longer your bones will get thicker and be harder to break and also the liquid surronding the bone will get thicker so it will be impact resitant e.g. like punching your fist togerther it will hurt but when you do it with boxing gloves on it wont hurt.

short term effects of exercise
When we begin to exercise the body has to respond to the change in activity level in order to maintain a constant internal environment (homeostasis). Here are the changes which must take place within the muscles, respiratory and circulatory system. Changes in the concentration of CO2 and O2 in the blood are detected by the respiratory centre which increases the rate of breathing

what my result was
This is my results for mesuring flexability and they are 10cm and 11cm and this shows how we mesured our flexability. Mark or take note of your best score, take a measure in cm or inches beyond the base of your foot, or you did not reach your toes, measure how far before the feet you were (a negative measurement score).
decreasing in resting heart
The number of times a walker's heart beats per minute while at complete rest. Resting heart rate will decrease as the walker's heart becomes larger and stronger with training. A low resting heart rate is an indicator of fitness. Your resting heart rate should be taken first thing in the morning, before getting out of bed. Find a clock or watch with a second hand or second display and take your pulse for 60 seconds.
effects of exercise
when you exercise your muscles slide against each other that crate friction and create little rips in the muscles and when they repair the muscle gets thicker and stronger.
If the rate of exercise is increased due to greater muscular activity, a point is reached at which not enough oxygen is supplied to meet the requirements of the muscle cells for aerobic respiration, as described earlier.
Anaerobic respiration cannot go on for more than a few seconds as the lactic acid/lactate builds up in the muscles and is said to cause cramp, or at least fatigue and soreness. In fact it is better to say that there is an equilibrium between the rate of production and the rate of removal of lactic acid/lactate.

what happens to your muscles
Your muscles work by pulling in pair and one of the work by pulling and the other one relaxes. muscles are made up of fibre that slide apart to get longer andrelax together to get shorter pull and as muscles pulls it get shorter it pulls across the joint of the arm.

respiratory
Respiratory rate is also known by respiration rate, pulmonary ventilation rate, ventilation rate, or breathing frequency is the number of breaths taken within a set amount of time, typically 60 seconds. A normal respiratory rate is termed eupnea, an increased respiratory rate is termed tachypnea and a lower than normal respiratory rate is termed bradypnea.
The respiratory system is the anatomical system of an organism that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs.

blood pressure
Blood pressure is the pressure exerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs. When used without further specification, "blood pressure" usually refers to the arterial pressure of the systemic circulation.
Here is an example of blood pressure 116/20 and this is a standing still and 120/58 and this is exercising for a minute.
Impact of Blood Pressure and Blood Pressure Change During Middle Age on the Remaining Lifetime Risk for Cardiovascular and the more blood that comes in the higher the blood pressure is and the less blood the pressure is going to be lower Your healthcare provider may take your blood pressure when you visit the office to check for changes in blood pressure.
The measurement blood pressure without further specification usually refers to the systemic arterial pressure measured at a person's upper arm and is a measure of the pressure in the brachial artery, major artery in the upper arm. A person's blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and in measured in millimetres of mercury (mmHg), for example 140/90.

heart rate
To see if your heart rate is chaging you will need to cheeck you pulse before, during and after the activity and how you do that you will need to cheeck your pulse per minute.
Heart rate is determined by the number of heartbeats per unit of time, typically expressed as beats per minute (BPM), it can vary with as the body's need for oxygen changes, such as during exercise or sleep. The measurement of heart rate is used by medical professionals to assist in the diagnosis and tracking of medical conditions.
