Development of foot surface pressure distribution measurement system for the training of soccer players

In order to improve the training level of soccer players, a monitoring system of pressure distribution and posture is developed. The dynamic distribution with 12 testing points of forces exerted against the surface of football shoes when kicking the ball is recorded by a wireless pressure measurement system and the posture during soccer kicking is captured synchronously by a camera system. The pressure measurement system includes the electric charge amplifier circuit, the analog to digital conversion circuit, the wireless transmitting and receiving circuit, and the computer data collecting and processing system. The principle of the hardware and software system is introduced in detail. It is very helpful for research staffs and coaches to acquire the dynamic pressure distribution and action of excellent soccer players and to train young soccer players.
