many people ask this very question and the answer is many big parts of the body. for example the heart, brain, blood and veins, muscles, lungs,bones, body weight. WOW! i know im pretty amazed too, how many things can be improved in someones body and its easy as riding your bike atleast half an hour every day. what does each one do? well here are the effects of each part if excersised while riding a bike.
LUNGS:
In order for your body to keep biking you need oxygen to make energy so you wont get tired easily. Exercising constantly develops the body`s ability to both take in and then deliver oxygen to the muscles that are being used.Which means you can ride your bike for a longer period of time.
BLOOD AND VEINS:
when you excersise your muscles they need more oxygen and nutrients to be delivered to them. the blood flow increases with more capillaries developing in the muscles.In addition there`s a greater opening of existing capillaries and more effective blood distribution.Plus your resting blood pressure decreases.
BRAIN:
Exercise causes the releases of endorphins (natural pain killers) in the brain.This is why after exercising you feel great,almost as if you`re on a high.This helps to combat the effects of stress.
MUSCLES :
Your muscles become more efficient at generating energy and combatting tiredness,so they can keep working for longer periods of time.
This happens in a number of ways….
* They can tolerate greater levels of lactic acid,the substance which causes that tying up feeling in your muscles,this is known as the lactate threshold.
*they can store more carbohydrate (the muscle fuel).
*there is an increase in the substances in the muscle which enable it to work longer and harder b
efore tiring.
HEART:
Your heart is a type of muscle,and it develops in response to exercise in a similar way to the rest of the muscles in your body.To provide for the demand for greater bloodflow around the body the following happens….
*it gets bigger and stronger.
*it becomes more efficient and can pump more blood with each beat.When you`re exercising flat-out this means you can exercise even harder.
*consequently your heart rate decreases,both while exercising and resting.
BONES:
Exercise increases both bone and muscle density.This means there is less risk of developing osteoporosis (brittle bone disease).
BODY WEIGHT :
To fuel your activities your body burns more calories.This results in both body weight and the amount of body fat decreasing.
