When it comes to recording accurate performance data for elite athletes, GPS technology can’t keep up, a Griffith researcher claims. Instead SABEL Labs has developed SABEL Sense, an alternative to GPS for tracking running speeds and distances, which is set to be a game changer in the sports performance and wearable technology industries. SABEL Sense is timely, as sporting organisations in particular consider their options. The AFL recently announced it had switched its GPS provider. SABEL Labs project manager and research fellow Dr Jono Neville developed a model which presents accelerometers as a viable alternative to GPS in the quest for improved athlete assessment techniques. His research, titled ‘A model for comparing over-ground running speed and accelerometer derived step rate in elite level athletes’, is detailed in Sensors Journal, which is currently published online and will be in print next month. Dr Neville said while Global Positioning Systems (GPS) are an important tool for workload management, the devices have limitations when it comes to changes in speed and direction and when they are used indoors, due to their reliance on external satellites. He said he compared inertial sensor data with GPS data, collected simultaneously from Brisbane Lions AFL players during 2009, to create a model which was highly accurate for running speeds. “There is a driving need for emerging technology like this in the sports performance industry,” the microelectronic engineer said. “When it comes to frequent and rapid changes in speed and distance, GPS just doesn’t cut it, although it’s still the most widely used technology. “We have found a data processing technique which allows us to extract data from an athlete and create an individualised model. “ Dr Neville said his technology will be key in monitoring training and game workloads. “This will assist in preventing things such as over-training, which is a major concern for elite athletes, to reduce risk of injury.” Dr Neville said individualised models are created automatically using SABEL Sense technology which can then be used to track speeds and distances. SABEL Labs is an entrepreneurial enterprise of Griffith University, specialising in wearable technology for sports and health applications. Its clients include many of Australia’s elite sporting organisations, research groups and Jaybird, a leading consumer electronics international company.

New technology for elite athletes that leaves GPS behind
Coralline algae (pink & lavender colour in the image above) are red calcifying algae found worldwide from the poles to the tropics, from high light environments such as the intertidal zone down to depths of up to 200m. They play a central role in coral reef ecology. Coralline algae produce limestone (calcium carbonate) that acts as glue or mortar holding coral fragments together and cementing and stabilising the reef framework. This allows coral reefs to resist the impacts of strong storms and cyclones. Coralline algae also provide hard substrate for coral larvae to attach to the bottom, and serve as habitat and food source for other reef creatures. However, despite the importance of coralline algae and the vital roles they play in reef ecology little is currently known in regards to their growth and ability to produce limestone (calcification) under future climate change scenarios. Ocean acidification is the result of world’s oceans absorbing approximately half of the excess CO2 released by human activities in the past 200 years. This increased in CO2 lowers the pH and carbonate ions needed for calcifying organisms (such as coralline algae) to make their limestone skeletons, and in doing so restricts their ability to form and maintain the reef framework. Our research and that from other groups has demonstrated vulnerability of coralline algae to ocean acidification and ocean warming. In light of their ecological importance, coralline algae sensitivity to human induced climate change is a critical issue for coral reefs in the Great Barrier Reef and worldwide. The aim of this project is to investigate the effect predicted future ocean acidification conditions have on the growth and calcification of coralline algae, and to determine if increased nutrient levels, often found on the reef during flood events, help or hinder their ability to calcify and perform the vital task of maintaining the reef framework. This project involves collaborators from a number of institutions such as Griffith University, The University of Queensland, the Great Barrier Reef Foundation, and the Australian National University.
