Description of methods used for collection/generation of data: Sixty-nine fencers (35 female) performed five lunges on six different surfaces (A F: A E composed of various materials placed between the aluminium piste and the concrete floor; F was only the concrete floor), during the 2024 US Senior National Championships. A triaxial accelerometer mounted on the tibia was used to measure tibial accelerations as a marker of impact shock. The accelerometer was aligned to measure acceleration along the longitudinal axis of the tibia and set to record at 1000 Hz with a sensitivity range of 100 g. Data acquisition was carried out via a logging system (Biometrics DL1001, Gwent, UK), which was attached to the participant using a tightly fitted backpack. The peak positive axial tibial acceleration was extracted for each lunge and the average was calculated from three lunges after discarding the highest and lowest values from each surface. 2. Methods for processing the data: SPSS and excel were both used to process the data. 3. Instrument or software-specific information needed to interpret the data: Excel and SPSS v29 4.
