Mobile Device Approach for the Measurement of Jump Flight Time.

Teenagers are mainly sedentary with the use of technological devices. However, technological devices may be part of recreational activities to challenge people to achieve better results. This paper described the acquisition of accelerometer data from mobile devices and BioPlux devices, measuring the correct jump flight time with the help of a pressure sensor in a jump platform. Also, this paper tested different methods for adjusting the calculation of the jump flight time, including the least-squares method, the subtraction of average error, and the multilayer perceptron. Currently, a mobile application is available with the Least Squares methods, but it will use the best method soon. Also, the method presented can be also incorporated in a game to stimulate the physical activity practice.
