RTA Sensor

The RTA Sensor (Rotational Traction Athlete Sensor) is used to measure torque as a function of high-frequency angle. It is mounted on a LwRTT (Lighweight Rotational Traction Tester) test apparatus and is the the first measuring device for the new rotational resistance test of the FIFA quality programme for football turf April 2024 Edition from page 17 to 19 (extract)

The device enables the simultaneous performance of the DETERMINATION OF PEAK TORQUE (FIFA TEST METHOD 2024-06) and DETERMINATION OF ROTATIONAL SHEAR STIFFNESS (FIFA TEST METHOD 2024-07) tests.

The sensor was designed and developed by PROLEXIA in partnership with LABOSPORT and based on the research of Loughborough University regarding injuries related to the rotational resistance of a sports surface, particularly on synthetic turf fields.

The sensor continuously measures torque and rotation during the measurement at a high frequency to enable analysis of the forces and stresses experienced by the player.

It is used by manufacturers of high-performance synthetic and hybrid turf, by groundsmens of major clubs, and by institutes accredited by sports federations such as LABOSPORT.
