Purpose

Principles

Questions

what is force summation
What is Force Summation?
  • It is the combination of forces produced by different parts of the human body.
  • It’s purpose is to achieve maximum force/acceleration and apply it to an object or the human body.
principles
Principles
  • Principle 1
  • Use as many body parts that relate to the movement as possible.
principles1
Principles
  • Principle 2
  • Body parts should move in a sequence with the bigger muscles (e.g lower body and trunk) leading the action. The smaller muscles closer to the object should be used last.

Principles
  • Principle 3
  • Muscle need to be used and accelerated with the correct timing.
principles3
Principles
  • Principle 4
  • All the muscles used must go through their greatest range of motion to achieve maximum momentum.
summary
Summary
  • The 4 principles of force summation are:
  • More muscles
  • Correct sequencing
  • Correct timing
  • Greatest range of motion
  • These 4 principles all help to generate maximum force.
stability and balance
Stability and Balance
  • It is important that all of these actions are performed over a stable base.
  • This allows maximum force/acceleration to be applied to the object.
