I'm Studying for my Fitness theory exam and have a week to take the test in order to recieve additional funding from the Government... I'm wondering if anyone has info on applying Biomechanics and Anatomy to Kung Fu:)

"This study compares the EMG activity of the TB, BB and
BR muscles during strikes with and without impacts. The
EMG analyses were done in the time and frequency domains.
For the frequency domain, an original method was
used to quantify statistically significant regions on the
wavelet power spectra, and it was proven be very reliable.
The results indicate that there are greater TB and BR
muscle activities for the strikes with impacts. The reasons
for this greater muscle activity are expected to be both
psychological, such as greater motivation, and biomechanical,
such as the need for stabilizing the joints during
the impacts. In addition, the results show that the wavelet
power spectra pattern for the three analysed muscles obtained
from the strikes with and without impacts were
similar. The results suggest that training forms or “katas”
should not replace training with pads. Although in both
types of training the movements performed present very
similar muscle activation characteristics, the magnitude of
the contraction of some muscle are greater for the movements
done with pads. In consequence, the relative time
spend in each type of training should be determined depending
on the application. For example, for participants
that need to increase strength either for combats or breaking
demonstrations, training with pads should be more
relevant than without pads. In addition, the methodology
developed in this article has other applications, such as
muscle control and rehabilitation evaluations for athletes
and non-athletes.
