**Abstract**

The desire of more and more segments of the population for self-improvement and self-expression through amateur sports has acquired a global scale. The evaluation and analysis of the amateur athletes' achievements in the chosen physical activity become of practical importance for most amateur athletes and open up the possibility of developing innovative interventions to stimulate the engagement in physical activity of as much population as possible. For this purpose, we have developed an elementary methodology for monitoring the achieved level of strength and overall endurance of students, designed to monitor and motivate amateur athletes of various types of physical activity. The purpose of this research project was to conduct the targeted analysis of the array of physiological indicators of those engaged in physical activity, and also to justify and test technologies for collecting and interpreting objective indicators of performing elementary physical test exercises and calculating their dependence on objective indicators of the cardiovascular system. Subsequently, we planned to develop a simple methodology for collecting, evaluating, and interpreting test information. We suggest using this technique in the daily training sessions of amateur athletes of various qualifications.
