该数据集名为NTNU步行速度—大腿+背部加速度测量，健康成年人，包含24名健康成年人在挪威进行的受控地面步行协议中佩戴两个Axivity AX3加速度计（右大腿和腰部，50 Hz）的数据。数据记录了三种速度等级和慢跑时的加速度信息，并已统一为每位受试者的parquet文件格式，每行代表一个原始样本。数据集共有24名参与者，176万样本，100%标记，总时长为9.8小时。数据适用于步行速度预测和人体活动识别任务，特别适合训练和评估步行速度分类器。数据集包含详细的标签词汇表、传感器轴方向说明以及加载和使用示例。

The dataset NTNU Walking Speed — Thigh + Back Accelerometry, Healthy Adults contains data from two Axivity AX3 accelerometers (right thigh and lower back, 50 Hz) worn by 24 healthy adults during a controlled overground walking protocol at three speed tiers and jogging in Norway. The data is harmonized into per-subject parquet files with one row per raw sample. It includes 24 participants, 1.76 million samples, 100% labeled, totaling 9.8 hours. The dataset is intended for walking-speed prediction and human activity recognition from dual-sensor thigh + back accelerometry, making it well-suited for training and evaluating walking speed classifiers. It includes detailed label vocabulary, sensor axis orientation notes, and examples for loading and usage.
