The interaction between player and field is an important factor in the assessment of the foundation. The various sports federations such as FIFA, FIH, and the World Athletics have set a number of characteristic values. One of these standardized values is the rotational resistance (or traction).
When the resistance against rotation is too high, too much stress may be placed on the joints of the sportsman. When the resistance is too low, the result can be insufficient grip with the effect of the sportsman slipping. For this reason FIFA has laid down a testing procedure with clearly defined values for the rotational resistance. The test foot is loaded with weights till it reaches 46 kg and must fall from a predetermined height before determining the resistance against rotation.
The Deltec Rotational Resistance Tester performs the measurements in a simple manner. During the development, special attention was given to ergonomic characteristics of the device. The weight for example consists of several plates.
The testing device consists of a tripod with bearings to ensure that the free fall and subsequent rotation are executed with as little friction as possible. After the drop, the required torque is determined by using the supplied torque wrench to rotate the test foot over an angle of a minimum of 45 degrees.
The (optional) Deltec Smart Carrier is a tool made for transport across the field in between the measurements. With some simple actions, you could fixate the Rotational to the carrier.
