Electromyographic Comparison of Grand Battement Devant at the ...

Peak: Muscle � Event � Condition
In the peak event, the graphs of both ABS and QA appear
in the plots as flat lines across the three conditions, meaning
there is essentially no difference across conditions in the
use of these two muscles at the peak of the battement (see Figures
1 and 7). As with stance, ES, HAM, and TA all
FIGURE 5. Gluteus maximus (left and right) by condition by event

increased in activation from barre to traveling and from
center to traveling, but did not demonstrate significant differences
between barre and center. And once again, the two
muscles demonstrating significant differences between all
three conditions are AH and GA, the lower leg muscles that
may be contributing to ankle strategy balancing mechanisms,
as previously discussed.
