In the paper, collision mechanics is used to analyze the hitting process of the bats in the baseball games. The model is constructed in the paper to testify the sweet spot on a baseball bat. The vibration impulse on hands is analyzed. And the hitting point of the center of percussion with zero vibration impulse is obtained by quantitative calculation. Some reasons are given to explain why practical...
This paper discusses the development and implementation of a system of remote sensing applied to surfboards to be used, especially, in athlete coaching. The developed system uses ZigBee technology to transmit data and uses the experimental analysis of mechanical stress of the materials for the acquisition of the variables to be analyzed. It is basically composed by two modules, called Remote Central...
The widespread of CNT (computer networking technology) brings great changes in the whole society, such as in manufacture, in life and in thinking. Meanwhile, it also leads to remarkable reforms in university education thoughts, teaching methods and models. The rapid development of computer and network promotes the continual scientificalization of college PE administration, which in turn results in...

There is no field and track event like pole vaulting which sets free the pole's properties to enable a vaulter to yield great jumping performance. The best choice of a pole should convert the total vaulter's take-off kinetic energy to the potential energy. However, this needs perfect matching with the dynamics. Studying non-causal dynamics of a vaulting model enables one to start from the desired...
