After studying various reasons for the fouls occurred at the take-off in long jump, the author believes that a good consciousness control ability plays a key role in the accuracy of board take-off, which will be a certain theoretical basis for the improvement of the take-off success rate.

Human-board interaction during a running takeoff in springboard diving;

The taking-off process in springboard diving motion is analyzed in this paper on the basis of mechanical model of diver/springboard system.

This paper analyses the technique of both approach and take-off on springboard diving,and primarily introduces the research of both methodological advancement and progeny,then makes elementary academic discussion on some biomechanical problem of springboard diving.
