Study on the action of tactile and strength sensors in determining the ball force on the volleyballers’ forearms

Abstract

In the previous issues of the magazine we described the computerised apparatus for the acquisition and assessment of the two-handed pass from below in volleyball, stressing the typology and efficiency of the sensors that constitute the hardware of the apparatus.
The present paper aims at analysing the strength sensor, evincing its utility in executing the pass and in the takeover from attack and service.
To develop the project ”Computerised apparatus for the acquisition and assessment of the two-handed pass from below”, efforts were made to detect and measure the ball force exercised on the player’s forearms in executing the takeover from attack and service. Thus, it may be assessed if the forces are equal on both forearms at the moment the ball is hit.
