### Force Summation

Purpose

Principles

Questions

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
• Principle 1
• Use as many body parts that relate to the movement as possible.
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.
Principles
• Principle 4
• All the muscles used must go through their greatest range of motion to achieve maximum momentum.
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
• 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.
Questions
• Explain in detail how to achieve maximum acceleration in a chest pass in basketball? (use force summation principles in your answer).
Questions
• Explain in detail how to achieve maximum power in a 3 point shot in basketball.
