A helpful tool for any Wing Tsun / Wing Chun enthusiast. The basis of this book is Oliver Gross' diploma thesis. The mechanism of the Wing-Tsun defensive movements is dealt with fundamentally and comprehensively. This takes place against the background of the existing theories (especially Dr. K. R. Kernspecht) and from different sports-science perspectives, such as sports psychology (cognitive architecture), biomechanics (utilization of the opponent's energy) and physiology. Finally, the findings obtained are compared with the common Wing-Tsun philosophy.
