A Study on the Kinetic Mechanism of Swing Motion of Sport Ball Hitting Event

As the economic life has been improved in the modern times, physical activities
intended improve health have been actively carried out. In particular, diverse kinds of
sport activities using tools are being performed in elite sports and social sports. The
swing motions using tools are aimed to precisely hit the target by transmitting the kinetic
energy generated by the human body to a racket, a club, a bat, and the like. That is, the
swing motions, which are expressed in various sport events, can be regarded to be acts of
making the target fly quickly, accurately, and in the desired direction using the tool. In
many sport events, athletes are continuously making efforts to improve the maximum
swing speed with a view to improving their athletic performance and sport instructors and
scholars are conducting kinetic and kinematic analyses to analyze the kinetic principle of
efficient swing motions.
Consequently, studies on swing motions utilized in sports have mainly been conducted
to realize the most efficient swing motion necessary to produce strong hit balls. Studies on
swing motions as such should be valuable as effective and efficient scientific learning
materials for elite players belonging to sport groups such as table tennis, baseball, golf,
and tennis groups. In addition, if materials that explain the swing motions by sport event
based on scientific studies of swing motions, it should be very helpful for the development
of table tennis, baseball, golf, tennis, etc.
