| Research Abstract |
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.
