Physical fitness together with cardiorespiratory fitness highlights the development level of the physical capacity of the human being. The explosive force (the detent) is a basic parameter that emphasizes the physical fitness level. The present study proposes to make a comparative analysis on the measurement of the lower limbs explosive force by two different methods: a classical method (the Alpha Fit test) and a modern method (the Myotest device). The Myotest device does not calculate and does not measure only the muscle performance, but it is a tool for improvement and analysis, whose purpose is to optimize the sports performance. The Alpha Fit test, conducted by direct recording with the metric strip, is based on measuring of the height jump. This paper aims at highlighting the most accurate method of measuring the detent. The modern methods of measurement, by means of the devices used, confer a special fidelity of the measured parameters, these being more successful than the classical methods of measuring the detent. The study subjects are represented by male and female students from the University Polytechnic of Bucharest. As a result of the analysis and of correlating the parameters registered between the two methods of measuring the explosive force at the lower limbs level (the Alpha Fit and the Myotest), there was found that there is a significant difference between the classical testing method (the Alpha Fit) and the modern method (the Myotest). © 2016 Published by Future Academy www.FutureAcademy.org.uk Keywords: Lower limbs force; Alpha Fit; Myotest device. http://dx.doi.org/10.15405/epsbs.2016.09.100
