Abstract
Biomechanical inquiries into the performance of surfing-related manoeuvres / movements are rare within the scientific literature. Most studies that have been conducted have taken place in a lab-based setting or via video analysis. Consequently, any direct kinematic or kinetic measures of surfers and/or their surfboards while wave-riding are almost non-existent. The primary aim of this thesis was to investigate the feasibility of using accelerometers to collect kinematic data of experienced surfers and their surfboards during wave-riding. The intent was to detect the acceleration waveform signals produced during the performance of specific surfing manoeuvres / movements. The secondary aim was to analyse these waveform signals to identify any significant trends in manoeuvre / movement execution in addition to any variations specifically between complete and incomplete bottom turn to top turn manoeuvre combinations. Notable results from the three main studies are as follows. Pop-up acceleration waveform signals were congruent between the accelerometers and the criterion motion-capture system and provided a reliable means to detect the start of wave-rides within the surfing session data sets. The five surfing manoeuvres / movements that were analysed generally had unique acceleration waveform signals. There were also several discrete acceleration and temporal variables that had a significant main effect for manoeuvre type. Acceleration waveform patterns were similar but differed in magnitude between complete and incomplete bottom turn to top turn manoeuvre combinations. Certain discrete acceleration and temporal variables were also significantly different between complete and incomplete manoeuvre combinations. Overall, accelerometers provide a valid and reliable way to collect kinematic data of surfing performances. This unique study has contributed to the body of knowledge in this domain and was the first to measure and evaluate acceleration data related to the lower-body and surfboard during the execution of several commonly performed surfing manoeuvres / movements.
