Milo Fitness Flipper TS-03, Руководство по обучению, Страница: 21 / 54

To show how the length of the implement changes the optimal foot position, Figure 17 shows the
optimal starting position of a simulated TS-04 (frame simplified for illustration), which is six inches
longer than the TS-03. The foot position is clarified in Figure 18 by the 90 degree relative angle
of the shoulder to ball of the foot to the line of action of the handle to the floor. This is with the
handle located at the same height as it was in Figure 14.
The optimal foot position behind the chest pad went from 4.0 inches on the TS-03 to 2.1 inches
on the TS-04. The longer the implement, the less the angular inclination for the same handle
height, and therefore the farther forward the optimal foot placement will be in this model. How
does this compare to a tire you may ask? Well, a 73.2 inch (1.86 m) diameter tire may not be easy
to find. The tires reported in some of the studies were 1.5 m by Keogh et al (Keogh, et al., 2010)
and 1.6 m by McGill et al (S. M. McGill, et al., 2009). Most of the other tires appear to be of a
