Long term effect on the skeletal system.

If you train your bone and body over a long period of time, they will become stronger, bigger and more efficient, because over that long period of time your bone and body got used to that type of training you've been doing.

 Skeletal muscles adapt to using more oxygen, the muscles and their capillaries become more efficient and can therefore work for a longer period of time.

Increase of bone density (bone strength) due to the increase in calcium production.

Increased Joint range of movement, because exercises increase the production of synovial Fluid. Synovial fluid increase our joint range of movements in the short term, but over a long period of times our joints dry out and they become stiff and we lose the range of movement, so the exercise we do creates the synovial fluid that allows us to increase our joint range of movements.

Our ligaments gets stronger, because they get used to the exercise you have done over that long period of time. The more exercise you do the stronger your ligaments become. if you put more weight on them they become stronger and more resistant.

Long term effect on the cardiovascular system.

If you train your body by doing loads of aerobic endurance, eventually all of your cadiovascular system wil become efficient.

Your breathing rate decreases at a resting point, your breathing becomes more efficient. You'll start taking less oxygen when your exercising, because your heart got bigger and stronger and increase of stroke volume, that means it will be more efficient on pumping blood around your body. pumping more blood in one beat than it used to with two pumps. The beats become more efficient , because the high intensity of exercise you've been doing over that period of time causes the wall of the left Ventricle to become thicker allowing a lot more blood leave the heart, so it doesn't have to pump has much. lowering your resting heart rate by even two beats a minute means your heart beats 2,880 less in just one day.

Your blood vessels will be able to handle significant amount of pressure, because of the training you've put them through over a long period of time. The number of Capillaries increases due to the regular exercise you've been doing, so your body becomes more efficient on taking waste products out, such as like carbon dioxide.

Long term adaptation of the muscloskeletal system.

Training your muscle over a very long period of time can lead to muscle hypertrophy.

 Muscle hypertrophy is when your training the muscle, Also it is caused by the increases in volume of contractile proteins within the muscles. The fibres in your muscle tear and after they start to recover, when they recover. They become stronger and bigger, so you can adapt to the weights your lifting.

If lots of your muscle tear at one it can lead to muscle injury, so lifting alot of weight that is impossible for you to lift will just injure you.

 Hypertrophy will happen (increased muscle size), because of the intense muscle training. Your muscles will realise that they cant lift that weight, so they become bigger and stronger for them to lift the weight.

Increased number of mitochondria, because they need to increase for you to lift the weight. Mitochondria stores energy within the muscle cell, so this increases the supple of ATP. Myoglobin is a site for oxygen storage within the muscle. The bigger your muscles become the more there will be for Myoglobin to store oxygen.

There will be an Increase of Tendon strength. Tendons are tough band of fibrous connective tissues that hole the bone and the muscle together. The tendons are there to withstand a high level of force. Tendons are just like muscles, if you train them they become stronger.
