wbe continuous blood circulation that helps in growth of brain cells and make them active.it makes our body warm and fit by using each part of our body.so those muscles that were not in use gets energy .it makes our mind peaceful
The body uses up stores of energy to restore the energy in muscles spent during muscular contractions. Oxygen delivery is also increased as this is used during aerobic reactions, which are the most efficient means of producing energy with either fat or carbohydrate. In absence of oxygen, only carbohydrate can be used as energy, and it is burned less efficiently.
There are a lot of things that happen when we exercise... if you are doing a cardio exercise, the brain tells the body to perform a specific muscle contraction (lets say jogging) the body releases calcium in the leg muscles to perform a contraction, this contraction is just a single action of a repetitious action that will take place when we perform jogging. The body also needs oxygen to make this contraction so the brain tells the body to take deeper or more air to support the muscle contraction needed to perform the cardio exercise . The increase of air intake will also mean an increase of "pumping" for the heart because it is our blood that brings the air (oxygen) to the muscle that contracts. Now we also have to consider the glycogen (carbs) that was stored by the body, it is use by the body as fuel or energy. Normally the body with use the glycogen for the first twenty minutes then it changes to fat for fuel specially if you are between 60% - 70% of your theoretical maximum heart rate. All these happen from the time you start your first step for jogging...
nothing happens...LOL!
nothing.
You will be fat.
Nothing
You will be healthy and your body will become stronger.
When you fail to exercise your body has to make do with what it has already. When this happens, your body has to take from other parts of your body to ensure homeostasis.
Heart rate increases.
After exercise your pulse becomes faster. The reason you get exhausted while doing exercise is you can't get enough oxygen into your body.
when you exercise, the fat stored in your body gets burned up..
They will first start to hurt, but they are actually becoming stronger and stronger!!
You'll most likely lose weight - but remember, too much exercise is never good for the body. Your body needs to rest at some point, so let it catch up with you.
Either you must exercise to burn the extra calories, or it will turn into fat.
