In many sports such as football, rugby, volleyball and handball, athletes frequently fall and slide at high  speed. One of the challenges manufacturers are facing is to create a surface that offers a low risk of skin injury during these common playing actions.

Labosport has developed a Skin Injury Test that realistically simulates the fall and slide of an athlete on the surface. The test apparatus measures both the coefficient of friction of the surface, and the temperature elevation felt by the players. Labosport has been measuring temperature elevation since 2017. The addition of coefficient of friction offers a unique technical solution.


  • Athlete weight : from 25 to 150kg

  • Falling / sliding speed : up to 5m/s

  • Sample size : 5m x 0,4m

Typical output from the load cell and the two lines are the vertical force (Fy), and the horizontal force (Fx). The coefficient of friction is the ratio between the two forces during the steady state phase in the middle of the impact event.

The Skin Injury Test uses bespoke apparatus to accelerate a mass and to create a sliding event on a surface with game-relevant kinetics and kinematics (speed and load). Temperature elevation is measured using thermocouple sensors, and the coefficient of friction ‘µ′, is measured using a 6-axis load cell whereby,
