If you do this correctly, you will also feel a straightening of the right knee -- this will make it easier for your lead (left) shoulder to turn under your chin and produce a much bigger upper body rotation
-- Slowly move your waist in circular motion to the left and to the right Cool down -- Breathe in, breathe out.
Studies have shown, surprisingly, that in cases of passive head and body rotation
, the resultant gain was higher than 1, more than in active head rotation .
That is, they measured the maximal hip alignment rotation before the beginning of its forward rotation, while other studies measured it at the beginning of the racquet forward movement, when hips might have started to rotate forward before the completion of the backswing (Akutagawa and Kojima, 2005) because the upper body rotation
followed the pelvis rotation (Kawasaki et al., 2005).
where [??] is the vector of reference point rate of the static system; [??] is the vector of body rotation
Reduced body rotation
on new TireHand models meets tire-handling needs while moving the center of gravity closer to the machine, minimizing the size of the loader or forklift required.
If you combine this with sustained body rotation
, you should produce a lower, more penetrating flight that bores through the wind.
Figures 3 and 4 illustrate the phase velocity of QT1 wave when the piezoelectric body rotation
about the [x.sub.3] and [x.sub.1] axes with varied rotation speeds and [gamma] = 0, respectively.
In practice you need to ensure that you fully cock the wrists in the backswing and then allow your body rotation
to initiate your downswing.
This design for long life is housed in a miniature body, and incorporates wire leads out the top, allowing body rotation
for close-center mounting.
After working on body rotation
and 'feeling the water' in week one, this week my personal swim coach Adam Riley of Total Swimming had me doing freestyle lengths using only one arm to concentrate on positioning.
