PHYSICAL-FITNESS TEST SYSTEM USING ACCELERATION SENSOR

摘要

The present invention relates to a fitness testing system using an acceleration sensor, of which a mobile device containing an acceleration sensor is attached to the body of the test subject and the test subject is induced to perform an exercise according to the fitness test instructions provided through the fitness testing process installed in a personal computer during which the acceleration signals are measured through RF communication for an output of the fitness test and assessment results. For this purpose, the present invention embodies a fitness measurement system consisting of an acceleration sensor device with a 3-axis acceleration sensor that is attached to the test subject to detect the 3-axis acceleration signals produced according to the test subject's movement and transmits the signals through RF communication; and an assessment and analysis unit that receives 3-axis acceleration signals from the acceleration sensor device through a host gateway and detects the maximum acceleration from the 3-axis acceleration signals received as the exercise intensity; wherein the execution processing unit of the assessment and analysis unit, in case the test items is “balance”, receives the x-axis acceleration signals, which are related to the left and right movement of the test subject, and z-axis acceleration signals, which are related to the forward and backward movement, via the host gateway and detects the trajectory according to the input x- and z-axis acceleration signals and the maximum acceleration value according to the forward, backward, left and right movements.
