Mobile hardware-software tools for the assessment and development of speed-strength qualities in cross-country skiers: opportunities and prospects

The purpose of the study is to identify the prerequisites for the use of mobile hardware-software systems with feedback for assessing and developing speed-strength qualities of skiers. Research methods: analysis of literary sources, questionnaires, and methods of mathematical-statistical data processing. Research results and conclusions. A high demand for wireless feedback systems in speed-strength training of skiers was revealed. According to coaches' assessments, such devices provide real-time monitoring of dynamic and kinematic parameters of movements, convenient data collection, and increased athlete motivation through results visualization. The implementation of such devices is an effective tool for planning and monitoring the training process.
