Different shapes of the skeleton help with different sports. There are 3 different types:
Mesomorph
As you can see a person that is a mesomorph is strong and muscular and a medium height. These suit types of sport like sprinting or swimming this is because these sport use power in their muscles which mesomorphs usually have.

Ectomorph

a ectomorph is usually tall and skinny this means the have a high centre of gravity which results in them being not so capable of competing in such sports like sprinting compared to mesomorphs. The sports that ectomorphs are usually good at are basket ball or volleyball.
Endomorph
An endomorph is someone who has a low centre of gravity and is usually quite stocky and fat. An endomorph would usually be suited in sports like rugby or sumo wrestling. They would not be suited in sports such as sprinting or swimming.
This photo shows an endomorph usually short and stocky helps in rugby because of the position they play which is a prop, and props need to be heavy and stocky to be harder to push in the scrum
Protection
Bones protect the internal organs such as the brain. The skeleton knows that the brain is essential to living so it protects it the most by making the cranium thick and high density also as it’s a fuses joint it adds extra protection as it cant move. This is to stop any bangs injuries to the head damaging the brain. Also the skeleton protects organs like the heart by providing a rib cage this is to make sure the vital living organs don’t get damaged in collisions. The skeleton has different thickness of bones depending on the are it is situated e.g. the cranium would be thick as its protecting the brain but another bone like the phalanges would be thin as there not protecting anything and if the were thick your fingers would be harder to move.

Movement /muscle attachment
Most of your bones are connected to some sort of other bone in your body usually at a flexible joint like the hip or elbow. This is because it helps the skeleton move and be flexible. The bones provide attachment for the tendons of the skeletal muscles and the ligaments of the joints. Most sports require different movements from the skeleton from drop shot in badminton to a hammer throw. Our muscles need our bones to cause the movement as the muscles are attached to the skeleton. The joints on our skeleton are the points of movement usually caused by bending or straitening.
Blood production
All bones contain bone marrow which is where blood is produced they produce red blood cells, white blood cells and platelets each of them are key to making the body work. The main bones that create the most red blood cells are the sternum and the pelvis. In the long bones there are two types of bone marrow: red marrow and yellow marrow. The yellow marrow is used during starvation, the body uses the fat in yellow marrow for energy. Red blood cells carry oxygen and nutrients to the body tissues.

Red blood cells- these contain haemoglobin and transport oxygen
White blood cells- these fight against infection
Platelets – the blood clotting agent
