Plyometrics are the modern method that allows individuals a greater power in development than it is possible by using strength training. Explosive power is expressed through the explosive jumping ability of the respondent’s neuromuscular system in order to express muscle strain in the shortest time interval. The case study had the aim to determine the effect of plyometric training on the explosive strength of the lower extremities measured by the Myotest. The purpose of the study was to determine the differences between the groups at the initial and final measurement. The study included 30 male respondents, the average age of 20.63 ± 1.58 (Mean ± St. Dev.). Using the Myotest and (CMJ), determined were the following: Height (in cm), Power (in W/kg), Force (in N/kg), and Velocity (acceleration in cm/s). The MANOVA-method was used, and it was reused for repeated measurements. We can conclude that there were no significant differences between the groups at the initial measurements p=0.102 on the multivariate level, as it is in the case of the univariate level height, p=0.130, p=0.906 power p=0.262; velocity, p=0.851, p>0.005. In the final analysis, a statistically significant difference during the initial p=0.002 in the multivariate level was found. The multivariate consisted of Height p=0.009, Power p=0.015. We concluded that at the initial measurement, the group membership did not affect any of the above variables, while at the final measurement it had a partial influence on Height p=0.009, Force p=0.015, an observer at univariate level, while at the multivariate level membership of the group had a large impact on the final measurement. It is recommended, therefore, to implement this program in all sports where a significant explosive power of the lower extremities is important, as concentric-eccentric contractions make an important contribution to the development of the same.
