The Triple Jump.

The Triple Jump.
General Considerations:
a) The 1st requirement to practice the triple jump is the jump master well in extension.
b) The triple jump requires no particular physical type, preferably the long-legged athlete.
Anatomical and physiological considerations:
One. Requirements to practice the triple jump.
High - strong legs - well proportioned - speed - flexibility - good coordination
2nd. Muscles acting
Impulse - twin-soleus - elevation - quadriceps crural - balance - arms deltoides
3rd. Heating.
Pedagogical Progression:
From the simplest to the most complex - Capacity imitative - Movies - photos - slides - Educational - Good sense.
Mechanical principles of the Triple Jump.
1 - The principles of the high jump and triple the distance apply.
2 - The distance depends on the jump:
Horizontal speed reached, speed control, conservation of speed and velocity distribution in the phases of the jump.
3 - To skip the athlete performs movements that generate opposing forces and horizontal whose values ​​will depend on:
Speed, body mass, thrust angle and drop angle, athlete's ability and air resistance.
4 - Angles equal thrust and fall (1 ° and 2 ° jumps)
5 - Acute angle favors the maintenance of speed.
6 - Position of center of gravity.
