1. Using the athlete as an example students describe their chosen athlete/ athlete’s sport in terms of Action/Reaction. Detail the effects this relationship on the athlete, there sport and the equipment used:
There is an equal and opposite reaction for every action. in relation hurdles, if a hurdler goes in towards the hurdle very fast, they will go over it and come off it fast. This is because of the force they applied on the track pushing back up on the athlete allowing them to clear the hurdle and continue running. This also applies as a hurdler must go into the hurdle with the knee leading, arms pumping and facing forward. Action/reaction is shown in hurdles through momentum - force or speed of movement. Hurdlers 'race' their lead leg with their opposite arm and by thrusting the arm forward then back, the leg will get more quick as a reaction of the force or momentum of the arm. The effect of action/reaction on the equipment used is shown in the way hurdlers want a centre of gravity that is just above the hurdle. This is seen as the hurdler's head barely rising as they go over the hurdle. For the hurdler to obtain a lower centre of gravity they can lean forward. |
