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).本数据集包含轴向峰值胫骨加速度（axial peak tibial acceleration）的时间序列数据。我们招募了10名轴向峰值胫骨加速度较高的跑步受试者。受试者在自选鞋具条件下，以3.2±0.2 m/s的地面跑步速度完成步态再训练课程，实验过程中提供基于轴向峰值胫骨加速度的实时听觉生物反馈。通过连接超轻量加速度计（accelerometer）的背包系统，我们在基于生物反馈的干预实施前后，采集得到轴向峰值胫骨加速度数据。有关数据采集与处理的详细细节，请参阅配套完整论文。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：在使用听觉生物反馈系统开展地面跑步实验时，跑步者何时会改变其峰值胫骨加速度水平。名为"Change-Point"的文件夹内含可通过Change-Point Analyzer v2.3软件打开的.cpa格式文件。轴向峰值胫骨加速度的数值还存储于兼容Excel格式的"change point analysis_data"文件中，该电子表格共包含10列，每一列对应一名受试者。每列数据依次包含无生物反馈条件下（1.5分钟基线期）的轴向峰值胫骨加速度数值，以及生物反馈条件下（2次各10分钟的实验阶段）的对应数值。每名受试者的有效检测试次总数为1853±88（均值±标准差）。
