1. Maximum effort
Principles 2 & 3

2. Learning goals
We are learning the difference between max force and max velocity.
We are learning to apply these principles to sport examples.

3. Well … maximal or near-maximal effort is required by most skills
associated with 2 principles:
Principle #2 - Maximum Force
Principle #3 - Maximum Speed

4. Some terms Force: a push or pull that causes motion, (N)
Velocity: how fast a body is moving in a specific direction (m/s)
Acceleration: the rate of change in velocity (m/s/s)

5. Principle 2: maximum force
the production of maximum force requires the use of all the joints that can be used
if one is left out, then the force will be reduced
use slower, controlled movements at high intensities
e.g. power lifting

6. the more joints that an athlete uses in a movement, the more muscles they contract and the greater force they can exert.

7. Recall: law #2
larger athlete - slower starts
more force to get moving

8. Principle 3: maximum velocity
the production of maximum velocity requires the use of joints in order from largest to smallest
larger, slower joint 1st
smaller, faster joints 2nd
maximum possible speed at impact (The Critical Instant) is achieved by adding the speeds of the preceding body segments

9. Baseball anyone?
What is the order of joint progression for Maximum Velocity in the baseball pitch?

10. That was easy …
Running

11. applications many sports require both maximal force and velocity
e.g. Baseball pitch
e.g. Overhand Skills
Some skills require less force thus fewer muscle groups.
e.g. badminton serve
e.g. archery
