- Description: Due to its associated injury risk, rotational traction is a frequently measured natural turf surface property. The most commonly used equipment, the studded boot apparatus (SBA), consists of a circular stud configuration that does not replicate the stud pattern on a regular football boot and may under or over estimate the surface traction. The aim of this study was to establish potential differences in the rotational traction measured between the current stud configuration on the SBA and the stud configuration on the most commonly used Australian football boots. The original studded boot had significantly higher rotational traction than the moulded stud sole or bladed sole. Location, quality and time tested all interacted significantly with the rotational traction measured. The current SBA may not accurately represent the rotational traction experienced by football players, and consequently may not be the most appropriate configuration to assess the relationship between rotational traction and injuries. © 2012 International Sports Engineering Association.

- Description: Little evidence exists on the surface temperatures experienced on third generation (3G) artificial turf sports surfaces. Without this fundamental information, it is difficult for local government organizations, governing bodies of sport, or facility managers to determine whether these surfaces are the most appropriate option for their venues and whether different management strategies need to be applied if these surfaces are installed in hot climates. Ambient and surface temperature, relative humidity, wind speed, and cloud cover were measured on two natural grass and two adjacent artificial turf surfaces. The highest temperatures were recorded on 3G artificial turf (M = 46.3°C, maximum = 86.6°C) and the lowest on irrigated natural grass (M = 24.1°C, maximum = 49.4°C). Overall, surface temperature was significantly associated with ambient temperature, wind speed , and cloud cover and with the interaction between ambient termperature and surface type. The current findings have implications for sport surface selection and management, particularly in hot climates.
