summation of force

Question 1

what is a kinematic chain?

Answer 1

process that determines how to best use body segments depending on the demands of the task

Question 2

what are the two ways force is summated?

Answer 2

• simultaneously

- sequentially

Question 3

what is simultaneous force summation?

Answer 3

• Where all body parts move at the same time to produce a force
• produce accuracy

Question 4

what is sequential force summation?

Answer 4

• Sequential combination of forces produced by different parts of the body, acting together to maximize force
• produce maximal force

Question 5

what principles need to be applied to create maximal force?

Answer 5

• The stronger and larger muscles of the thighs and trunk are moved first followed by the smaller and faster muscles.
• Sequentially accelerate each body part so that optimum momentum passes from one body part to the next.
• Each body part should be stable so that the next body part accelerates around a stable base to transfer momentum.
• Use as many body parts as possible, so force can be applied over the maximum possible time.
• Follow through is important to prevent deceleration of last segment and safe dissipation of force.
• Ensure all forces are directed towards the target.
