Long term effects

TENDON
Increase in tendon strength.This happen when you exercise because your tendon gets stronger but if you use it too much then it wares out so it becomes weaker over time.

BONE DENSITY
increase in bone density. This means that your bones become more tightly compact so bones become denser. This happen because when you exercise the high impact of the outside of your bone and there forms small crack that then re-heal so strengthing bone and  bone becomes more compact because so then it becomes more harder so for example footbollers have high bone density then their is less chance of breaking their bones.

HYALINE CARTILAGE
Increase in thickness of hyaline cartilage increases with exercise so when the movements of joints becomes easier to do. This is because the body need to get used to exercise so it creates more hyalike cartilage.

SYNOVIAL FLUID
Increase production of synovial fluid because the movement and flexible of the joints becomes easyer to do like in tennis where movement is essential

CARTILAGE
More cartilage from exercise because so it then can take impact better and then their will be better movement because the cartilage between your bones do not allow your bone to rube against each other so you are quicker, less pain and take more impact.

LUNG CAPACITY
Increase in lung capacity because your diorama and intercostal muscles increase  in strength so your ribs open more because the stronger they are the better they can push the ribs so more air goes into your lung where alveoli are to transfer to the blood stream. This could help for example long distance swimmers and deep sea divers because you can hold more oxygen.

MUSCLE
Muscle increase because they get small tear and then repair so they get bigger.When you exercise your muscle tear so your heart is a muscle so it gets stronger from tearing so the the stroke volume increases this is important in weight lifting where you need to lift as much as possible.

BLOOD CELLS
Your red blood cells increase from exercise because it need to get more oxygen to your body so it produces more but when you get used to the exercise there are more blood cells in the body.
