HG Biomechanics Recap

Which of the following statements is NOT beneficial when playing sports that require good stability and balance.

• You are able to generate more power and force from a stable base
• You are harder to knock over in sports such as rugby and sumo
• You are less likely to fall over
• You are able to change directions quickly
• Your line of gravity stays inside your base of support

A person is most stable when?

• High COG, Narrow BOS and LOG inside BOS
• Low COG, Wide BOS and LOG inside BOS

In order to generate the maximum force when throwing a ball which of the following is NOT a factor of Force Summation?

• Use as many segments as possible
• Use the correct order
• Use small muscles first then large muslces
• With the correct timing
• Using the greatest Range of Motion (ROM)

How does Valerie Adams use Force Summation to throw the shotput as far as possible.

• Valerie Adams relies solely on arm strength to throw the shot put.
• She uses only her upper body to generate power for the throw.
• Force Summation is not a technique used in shot put throwing.
• Valerie Adams uses Force Summation by generating power from her legs, transferring energy through her core, and applying it to her arms for maximum shot put distance.
