The focus of this review paper is on biomechanical ana-
lyses, permitting one to draw conclusions on the charac-
teristics/parameters, which can be used for reasoning
the observed results. There are a plethora of further stu-
dies which are not included, for example: studies that
are only descriptive in nature; studies concentrating on
repeating previous investigations; and theoretical model-
ling and simulations for skill optimization.
