The acceleration and angular velocity of swimmer's lumber in breaststroke swimming was measured using an inertial sensor logger, and it was accurate to estimate the swimming acceleration along the propulsive direction using the sensor data. Although it was difficult to execute the estimation in real-time by the methodology, it was found that the measured acceleration along longitudinal axis of swimmer's trunk was partially corresponded with the swimming acceleration. The findings were applied to develop a device, which was able to express changes of the swimming acceleration by frequency of sound. The developed system made possible the feedback of the swimming acceleration during breaststroke swimming.

利用惯性传感器记录仪测量了蛙泳游泳时运动员身体的加速度和角速度，并利用传感器数据准确地估计了沿推进方向的游泳加速度。尽管该方法难以实时进行估计，但发现测量的沿游泳者躯干纵轴的加速度与游泳加速度部分对应。研究结果被应用于开发一种设备，该设备能够通过声音频率来表达游泳加速度的变化。所开发的系统使得蛙泳游泳过程中游泳加速度的反馈成为可能。
