The main objective of the study was to determine to what degree higher muscular activity,
achieved by increased load in the extension phase (eccentric muscle action) of the vertical …

In this study, we attempt to answer the following question: To what degree the higher
muscular activity determined by increased load in the extension phase (eccentric muscle …

In many sports vertical jumping is important. This study compared neuromuscular
functioning of the lower extremity muscles together with some kinetic and kinematic …

The increase of the resistance of the movement-on the basis of the dynamic fundamental
law Ft= mv (Force Impulse= Change of the Kinematic Impulse)-can be achieved either by …

The aim of this research was to determine the basic kinematic parameters of the high jump
as well as the impact of changes in kinematic parameters on the height of the jump, and …

The aim of this study was to identify the determinants of peak power achieved during vertical

In the literature, drop jumping is advocated as an effective exercise for athletes who prepare
themselves for explosive activities. When executing drop jumps, different jumping …

The validity and reliability of the jumping ergometer method for evaluating performance in
two-legged vertical countermovement and serial rebound jumps were investigated. The …

For 13 subjects the performance of drop jumps from a height of 40 cm (DJ) and of
