Force Summation
As we know, in order to generate momentum a force must be applied to a body
An athlete is able to achieve a maximum velocity or force by the transfer of momentum through successive body part movements.

Force Summation
Rule 1: Use All Body Segments
To maximise muscular force we want to use as many body segments as possible.Slide4
Force Summation
Rule 2: Stretch Out
Before we begin the sequence of body movements we should stretch muscles out to their optimal
length to
allow muscles to be contracted with max force.Slide5
Force Summation
Rule 3: Sequencing of Body Segments
Generally we move larger muscle groups first and smaller muscle groups last
Force generated by the larger muscle is groups passed on to the smaller onesSlide6
Force Summation
Rule 4: Timing of Body Segments
To produce max force we need to ensure that the right body segment is adding to the overall force at the right time
If timing is out of order movement will lack co-ordination and force generation is lessened or lostSlide7
Timing of body segmentsSlide8
Force Summation
Rule 5: Full Range of Motion
We need to move body segments through the greatest range of motion that we can.
Greater the range of motion, the higher the speed of the extremities on release/contact
