Force Summation #2

Define Force Summation

• The combination of forces produced by different parts of the human body.

• The greater the number of joints used the greater the applied force

• Move the joints supported by the large muscles that are in the centre of the body first, before the joints supported by the small muscles that are found at the ends of the arms and legs.

• Body segments need to be used at the correct time to give maximum momentum

Define Sequencing of Body Segments

• The combination of forces produced by different parts of the human body.

• The greater the number of joints used the greater the applied force

• Move the joints supported by the large muscles that are in the centre of the body first, before the joints supported by the small muscles that are found at the ends of the arms and legs.

• Body segments need to be used at the correct time to give maximum momentum

Define Use of Body Segments

• The combination of forces produced by different parts of the human body.

• The greater the number of joints used the greater the applied force

• Move the joints supported by the large muscles that are in the centre of the body first, before the joints supported by the small muscles that are found at the ends of the arms and legs.

• Body segments need to be used at the correct time to give maximum momentum

Define Timing of Body Segments

• The combination of forces produced by different parts of the human body.

• The greater the number of joints used the greater the applied force

• Move the joints supported by the large muscles that are in the centre of the body first, before the joints supported by the small muscles that are found at the ends of the arms and legs.

• Body segments need to be used at the correct time to give maximum momentum

What happens when the timing and sequence of a movement is wrong?

• It will look uncoordinated and not produce maximum force

• It will look coordinated and provide maximum force

The greater the range of movement

• the more efficient your arms rotate

• the limbs should be straight and strong at the time of release

• the better the extension & flexion of arms

• the higher the speed of the extremities on release/contact

At time of release the muscles should be

• stretched out, straight and strong

• contracted

• adjacent myofilaments in the sarcomeres slide closer together

• eccentric contractions
