Chapter 12

Question 1

List the first 3 principles of biomechanics

Answer 1

1. Stability
2. Production of Maximum Force
3. Production of Maximum Velocity

Question 2

Explain the Principle of Biomechanics: Stability

Answer 2

The greater the mass, the lower the centre of mass the the base of support. The larger the base of support , and the closer the centre of mass is positioned to the base of support, the more the stability increases

Question 3

What is centre of mass

Answer 3

The imaginary middle point around which the mass of an object or person is balanced

Question 4

What is a base of support

Answer 4

The supporting area beneath an object or body, its limit are defined by the point of contact with a supporting surface

Question 5

Explain the production of maximum force

Answer 5

The production of maximum force requires the use of all possible joint movements that contribute to the tasks objective.

Question 6

Explain the production of maximum velocity

Answer 6

the production of maximum velocity requires the use of joints in order from biggest to smallest.
