Transcript Force Summation

Force Summation
 In
order to generate momentum, a force
must be applied to the object. When we
are trying to give the object momentum,
the amount of the momentum we can give
is determined by the sum of all the forces
generated by different body parts.

There are 5 basic
guidelines for giving an
object as much linear
momentum as possible
1. Using Body Segments:

We should use as many body segments as
possible when trying to give the object maximum
momentum
 This is because we can maximise the muscular
force that each muscle group associated with
each segment can generate.
 In golf, which body segments are being used? –
legs – hips – trunk – shoulders - arms - wrist.
2. Stretch out:



Before completing any exercise we need to
stretch our muscles to their optimal length.
this allows the muscles to be contracted with
optimal force. We do not want to over stretch
or over reach as this in turn has a negative
effect on the force produced.
How do we see this being applied in golf?
3. Sequencing of Body segments:

Generally, to give maximum momentum to an
object, we move the larger muscle groups first,
followed by the smaller muscle groups closer to
the object last.
 the benefit of this is that the momentum
generated by larger muscles about larger
segments can be passed on to the smaller ones
until we make contact/release.
 In golf, how is this principle applied?
4. Timing of Body Segments:



Generally, to give maximum momentum to an
object (striking) we need to make sure that the
right body segment is adding to the overall
momentum at the right time.
What happens if the timing is out of order? Not
only does it lack co-ordination, but maximum
force generated is lessened
How does correct timing ensure maximum
momentum? It means we use those longer
muscle groups first and the smaller muscle
groups last.
5. Full Range of Motion:
 Generally,
to give maximum momentum to
an object, we need to move the segments
through the greatest range of motion that
we possibly can.
 Benefit of this = the greater the range of
motion, the higher the speed of the
extremities on release/contact.
