The most accurate data for measuring the explosive power of the lower extremities are provided by modern measuring instruments and apparatus for measuring the maximum isometric force of the leg extensors with associated hardware and software, tensiometric probe inside the foot platform, force reader with PC such as Quattro Jump, Ergo Jump, Myotest. Given that explosive power is one of the essential abilities in volleyball, which contributes to the vertical jump of volleyball players, this research would aim to present and assess the validity of these measuring instruments. The method of work is to collect relevant literature in the period from 2007 to 2021 and analyze them. The results showed practicality, efficiency, the economy in transport, validity, reliability, as well as the static correlation of tested variables. The research included nine original scientific papers, which satisfied the research problems and could provide an answer to the set goal. With the help of the found research, we can freely say that the application of measuring instruments for estimating the explosive power of the lower extremities in recreation and sports is in expansion and an increasingly common ally of coaches in initial measurement, tracking form, and designing training sessions.
