Abstract

The authors used an self developed inertial sensor, which provides triaxial accelerometers and gyroscopes, RF capability and 2GB on-board memory in a waterproof casing attached to swimmers to investigate the symmetry in freestyle swimming. The recorded acceleration data was filtered using a high-pass Hamming windowed FIR filter to remove the sensor orientation from the wanted signal. The signal was then analysed using a zero-crossing detection algorithm to find the induvidual strokes and the differences between left and right arm stroke durations.
