Data from: “Change point detection of peak tibial acceleration in over-ground running retraining”

This dataset contains the time series of axial peak tibial acceleration. We recruited 10 runners with high axial peak tibial acceleration. The participants performed a gait retraining session whilst running overground at 3.2 ± 0.2 m/s in self-selected footwear. Real-time auditory biofeedback on axial peak tibial acceleration was provided. The axial peak tibial acceleration was detected before and during the biofeedback-based intervention using a backpack system connected to a very lightweight accelerometer. We refer to the full paper for details on how the data were collected and processed. Data are from an experimental protocol approved by the Ethics Committee of Ghent University (bimetra identification number 2015/0864). The present dataset has been used to determine when runners change their level of peak tibial acceleration during over-ground running using an auditory biofeedback system. The folder 'Change-Point" contains the .cpa-files to be opened in the Change-Point Analyzer v2.3 software. The values of axial peak tibial acceleration are also stored in an Excel-compatible file 'change point analysis_data' . The spreadsheet comprising of 10 columns. Each column represents a participant. A column contains the values of axial peak tibial acceleration of the no-biofeedback condition (1.5 min. of baseline), followed by the biofeedback condition (2x10 min.). The total number of trials detected per participant equals 1853 ± 88 (mean ± SD).本数据集包含胫骨轴向峰值加速度（axial peak tibial acceleration）的时间序列数据。本研究招募了10名胫骨轴向峰值加速度偏高的跑步者。受试者以3.2±0.2 m/s的配速在户外跑步，期间开展步态再训练，并穿着自选跑鞋。系统会提供针对胫骨轴向峰值加速度的实时听觉生物反馈。在基于生物反馈的干预实施前及过程中，通过连接超轻量级加速度计的背包式系统采集胫骨轴向峰值加速度数据。 有关数据采集与处理的详细流程，请参阅完整研究论文。 本数据集源自根特大学伦理委员会批准的实验方案（bimetra识别编号：2015/0864）。 本数据集曾用于探究跑步者在使用听觉生物反馈系统进行户外跑步时，何时会改变其胫骨轴向峰值加速度水平。名为‘Change-Point’的文件夹内包含可通过Change-Point Analyzer v2.3软件打开的.cpa格式文件。 胫骨轴向峰值加速度的数值同时存储于兼容Excel格式的'change point analysis_data'文件中。该电子表格共包含10列数据。每一列对应一名受试者：每列数据首先包含无生物反馈阶段（1.5分钟基线期）的胫骨轴向峰值加速度数值，随后为生物反馈阶段（2组，每组10分钟）的对应数值。每名受试者的有效检测采样总次数为1853±88（均值±标准差）。
