An accelerometer system was used to measure the characteristics of the motion of 133 healthy male soccer athletes in a 30-s walking test and the data obtained were analysed using the gait evaluation differential entropy method (GEDEM). GEDEM processes gait acceleration data and calculates an index that provides a quantitative evaluation of a subject's gait, at low cost and with negligible effect on the subject. The GEDEM index was not significantly correlated with age, body weight, body mass index, or the number of years of active training. The GEDEM value for the anterior-posterior axis showed a small negative statistically significant correlation with height and the vertical axis was moderately and statistically significantly positively correlated with the time spent training per week. The triaxial accelerometry system described here is easy for subjects and testers to use, and enables measurements to be made on the sports field to evaluate an athlete's musculoskeletal condition with respect to gait stability.
使用加速度计系统在30秒步行测试中测量133名健康男性足球运动员的运动特征，并使用步态评估微分熵方法（GEDEM）分析所获得的数据。GEDEM处理步态加速度数据，并计算一个指标，该指标以低成本且对受试者影响可忽略不计的方式对受试者的步态进行定量评估。GEDEM指数与年龄、体重、体重指数或积极训练年限均无显著相关性。前后轴的GEDEM值与身高呈微弱的负相关，垂直轴与每周训练时间呈中等程度且具有统计学意义的正相关。这里描述的三轴加速度测量系统便于受试者和测试人员使用，并且能够在运动场上进行测量，以评估运动员关于步态稳定性的肌肉骨骼状况。
