Background: Artificial turf is considered a feasible global alternative to natural turf by many sports governing bodies. Consequently, its ability to
provide a safe and consistent playing surface regardless of climate becomes essential. The aims of this study were to determine the effects of
artificial surface temperature on: (1) mechanical properties of the turf and (2) the kinematics of a turf-sport related movement.
Methods: Two identical artificial turf pitches were tested: one with a cold surface temperature (1.8°C–2.4°C) and one with a warm surface temperature
(14.5°C–15.2°C). Mechanical testing was performed to measure the surface properties. Four amateur soccer players performed a hurdle jump to sprint
acceleration movement, with data (contact time, step length and hip, knee and ankle kinematics) collected using CODASport (200 Hz).
Results: The temperature difference had a significant influence on the mechanical properties of the artificial turf, including force absorption,
energy restitution, rotational resistance, and the height where the head injury criterion was met. Both step length (p = 0.008) and contact time
(p = 0.002) of the initial step after the landing were significantly longer on the warm surface. In addition, significant range of motion and joint
angular velocity differences were found.
Conclusion: These findings highlight different demands placed on players due to the surface temperature and suggest a need for coaches,
practitioners, and sports governing bodies to be aware of these differences.
