Research on hand pressure information collection when pass, smash, blocking, mat-ball and serve

摘要

Pass, smash, blocking, mat-ball and serve are the five volleyball basic skills. How to improve competition results, and reduce sports injuries simultaneously, has become the focus of attention of volleyball teaching and training. Utilizing PVDF's advantages of fast response, high sensitivity, easy to process and so on, a method to collect hand pressure information when playing volleyball has been put forward. The sensor array, signal conditioner and power supply circuit have been developed. Three sets of quasi-static test prove that the sensors are accurate and reliable. Frontal underhand serve experiment proves that this method is practical and able to effectively acquire volleyball player's hand pressure information which can provide scientific basis for the further research of volleyball special training program design.
