Method: This experiment includes two parts, the first part: using three dimensional motion capture system to examine self-manufactured six-axis wireless inertial measuring unit. After that, using intra-group correlation to examine the reliability of using three-axis accelerometer and three-axis angular velocity accelerometer device. The second part: subjects were 12 healthy college male subjects, using three-dimensional motion capture system and self-manufactured six-axis wireless inertial measuring unit to measure machine fly exercise of the forearm space-time parameters. Three different action frequencies were given during the experiment and using self-implementing algorithm to determine the action period of time and comparing the correlation between self-manufactured six-axis inertial device and three-dimensional motion capture system. Result: Intra-class Correlation Coefficient of self-manufactured six-axis inertial device at all axis using 30 times repeated active curve was 0.995. Self-manufactured six-axis wireless inertial measuring unit and three-dimensional motion capture system were highly correlated against each other, the Pearson correlation coefficient was γ = 0.999 at all six axis. Using two different devices to record three different velocities and from 12 subjects all showed significantly correlation against each other. Conclusion: This self-manufactured six-axis wireless inertial measuring unit has high correlation and high repeatability compared with the commonly use motion device and therefore it is convenient to determine human body space-time parameters as well as using it to record during the resistance training session for personal exercise prescription purpose.
