Abstract
The topic of my project is to test the importace
of the right ballet shoes to avoid injuries and
at what age would be the best to go on pointe
what i will do is i will take some young people
and make them do some basic steps and then do
more complex ones. And then do the same thing
with the older people. I will se the impact they
made and see if it affected the feet.
3
Purpose
My purpose is to investigate if the pointe
slippers used too early in the ballerinas can
affect their feet.
4
Problem
How to avoid injuries caused by the wrong use of
ballet shoes
5
Hypothesis

• If ballerinas are too young and they change from
  the split sole to a pointe shoe at a young age
  damages will be caused to her muscles and bones
  due to the higher presure on her foot.

Background
The toes are straight while en pointe other wise
you would hurt your feet and toes. don't expect
to be en pointe right after you start dancing it
won't happen, you have to build up strength in
your ankles. injuries occur as a result of poor
intrinsic foot muscle strength. The intrinsic
foot muscles are tiny little muscles that start
and end within the foot, that help control the
position of a ballet dancers arch, and are
responsible for the control of her toes within
the shoe en pointe. If these small muscles are
not working effectively, larger muscles called
the extrinsic foot muscles, that originate
further up the leg become overused, as they
attempt to perform two roles. This often leads to
conditions such as Anterior Compartment
Syndrome, Stress Fractures of the shin bone
(tibia), or Medial Tibial Stress Syndrome ,
commonly known as Shin Splints.

Background Continuing

• , In many other sports, orthotic devices may be
  worn in the footwear required that will help
  stabilize the arch and settle symptoms related to
  poor intrinsic muscle strength. Unfortunately, in
  ballet slippers, these orthotics cannot be worn
  (although many have attempted this!) so the
  dancer is often left to live with symptoms, or
  have repeated extended breaks from dancing.
• However for many people, the isolated strength
  needed in the feet must be specifically trained,
  especially nowadays, as many children who grow up
  in cities spend little time bare foot on
  different surfaces, which naturally trains the
  tiny intrinsic muscles of the feet. Understanding
  how these muscles should work when dancing is
  imperative in a long, injury free, career in
  dance.

Methodology

• ask older people to do the same steps
• Graph results
• Buy materials to do final project
• Do final project.

• Decide on a topic
• Do hypothesis
• Do proposal
• Buy clay to do experiment
• Ask young people to do basic steps then some
  higher grade steps
