An assessment of a volleyball player’s loads in a match on the basis of the number and height of jumps measured in real-time conditions

Jump Performance During Official Matches in Elite Volleyball Players: A Pilot Study

“…The data showed no changes in the types of jumps performed and in their intensities among the different game sets in the sample study. Thus, these results showed stable data between sets which is in opposition to results from a study by Wnorowski et al (2013) with elite male Polish players (one match). They found a reduction of the relative jump heights throughout the match.…”

“…Therefore, they can adjust their actions to the game situation to control their efforts better and to be able to maintain their jump ability throughout the rally and the match. The total relative jump height values for the different actions of the study sample are lower than the ones reported in previous research on elite, male Polish volleyball players (Wnorowski et al, 2013). These differences could be related to the levels of players, training performed, or the way height was measured (inertial sensor vs video analysis), among other possible factors.…”

“…Less is known about jump intensity. A study with elite, male Polish players showed that players executed their jumps during the game at between 77-90% of their maximal potential and that the intensities of these jumps changed throughout the game (Wnorowski et al, 2013). However, another study with elite, female Argentinean players found, in assessments carried out after matches, that players’ maximal jumping ability did not decrease after a match (Esper, 2003).…”

External and internal Load and their Effects on Professional Volleyball Training

“…When analysing jump height, it was determined that players performed fewer maximal (81-100 cm) and more submaximal (50-80 cm) jumps in all sessions. Also, a study on a Polish team shows that during a game, 77-90 % of players perform maximal jumps [40]. Nevertheless, the values obtained in the present study were absolute values that were not adjusted to each player, thus casting doubt concerning the comparison between the players' effort in training versus in competition.…”

Analysis of jump load during a volleyball season in terms of player role

“…13 Other studies point out that SE, who participates in almost every rally in order to send the ball to a partner so that he/she spikes, perform the highest number of jumps. This occurs in top-level competitions in which setters try to set while jumping, but their jump load is defined as a submaximal effort, 2,23 which implies fewer injury risks because of a lower jump height. 24 Regarding the macro-cycle, the influence of the transformation and realization phases on jump load may point at the specificity of these periods in terms of training actual game demands Moreover, an increase in jump load during the transformation phase, followed by a decrease in the realization macro-cycle, should confirm a common reduction load employed in tapering-phases prior to crucial events (important matches, competition final, etc.).…”
