A wireless framework for movement activity monitoring of sprinters The most important factor for success in short distance track and field running is an optimal combination of the step frequency and step length. Evaluation and analysis of step parameters allows enhancing the overall performance and avoiding injuries. This paper presents a low-cost, lightweight wireless solution. The developed system derives information about step parameters from accelerometer and gyroscope measurement results and fulfills a real-time analysis of sprinter's activity. The described instrument supports coaches and help to optimize the training process.
