INTRODUCTION: Using Compact Rio a standalone data logger to analyze snow profile felt through a snowboard while in use on both artificial and natural surfaces. To see if this form of data collection is suitable for further analysis on the rider to snowboard interaction and if it impedes the riders ability thus limiting the suitability of this method of testing. METHOD: A snowboard was instrumented with two Monitran accelerometers and these were connected to Compact Rio. Compact Rio was running a bespoke user interface written in Labview, which was designed specifically for collecting data whilst on a snowboard by National Instruments the Manufacturers of Compact Rio. A series of lest runs were conducted at Bracknell Dryslope and Milton Keynes Snowdome. This allowed testing on both snow and artificial matting commonly used by UK snowboarders, The rider was to perform a series of carved, linked turns during a 10second testing period triggered by the rider. The random snow profile was collected from these runs and combined into a single data set.To obtain an overall snow profile the FFT was performed on the data which gave a Power Spectral Density snow profile. This snow profile showed the frequencies on the different surfaces and how closely correlated the two were. RESULTS: The data collected with Compact Rio showed that is was indeed possible to collect snow profile data. It also highlighted the difference in frequencies between snow and man-made snow surfaces such as permasnow used for this testing see Table 1. Results are also plotted in Figure 1. DISCUSSION: In addition to providing a benchmark data series for analysis, the testing was to determine if Compact Rio was suitable for further analysis of the rider to snowboard interaction and whether it could affect the results collected due to impeding the riders movements. The feedback from the rider was that Compact Rio was lightweight and when carried in a secured and properly fitted Sports backpack hardly noticeable. CONCLUSION: The experiment showed that Compact Rio is not only able to collect data from an instrumented snowboard, but that it is also rider friendly in comparison to previous testing methods used.
