1. High Jump

2. How its evolved The way the athletes jump has changed over time.
Dick Fosbury revolutionised the sport by being the first athlete to jump with this technique.
Since then every athlete in the sport has copied him.

4. Further Improvenments Possible
They could get springier shoes to help with the jump.

5. Equipment or Athlete
The athlete is definately more important as there is very little equipment used.
Over time the bars have been made lighter so that it is easier to knock them off.
This means the athlete must have a better jump to fully clear the jump.
