2. Relationship between curvilinear sprint performance, hip strength, jump performance and reactive strength in elite youth soccer playersAžbe Ribič, Matic Sešek, 2025, izvirni znanstveni članek Opis: The aim of this study was to investigate the relationships between hip strength, vertical jump performance, reactive strength index, and curvilinear sprint (CS) performance and to compare these variables between different playing positions in youth soccer players. Thirty-four players completed two test sessions. Hip adduction and abduction strength was measured using a hand-held dynamometer. A force plate was used to measure the height of the countermovement jump and the drop jump as well as the contact time, from which the modified reactive strength index and the reactive strength index (RSI) were calculated. The CS was tested on the penalty arch of a soccer pitch. One way ANOVA was used to test the effects of playing position whereas the Pearson's r was used to test the relationship between variables. There were no significant differences in the measured variables between defenders, midfielders and attackers (p≥ .140). Along with RSI, which showed significant moderate to large correlations (r = -0.39 to -0.59), hip abduction strength was also significantly associated with CS split times (r = -0.36 to -0.38). Results emphasize the relevance of ankle reactive strength and hip strength for CS performance and supports the inclusion of ankle and hip-specific strength exercises in the training of youth soccer players.

3. Determining power training needs using the force-velocity profile (imbalance) in elite female volleyball using different vertical jumpMarko Joksimović, Dana Badau, Rebaz B. Tawfeeq, Nebahat Eler, Raul Ioan Muntean, Adela Badau, Matej Plevnik, 2025, izvirni znanstveni članek Opis: This study aimed to evaluate the Force-Velocity (Fv) profile of elite female volleyball players during the Squat Jump and Countermovement Jump to define the Fv profile of female athletes based on strength, power, and individual mechanical characteristics. The goal was to enhance training efficiency and improve performance in ballistic movements. For this study, we recruited 12 elite female volleyball players from the Montenegro U19 national team. The Fv profile was assessed in two types of muscle contractions: the Squat Jump (concentric contraction) and the Countermovement Jump (eccentric-concentric contraction) to determine Fv imbalance. First, the height of the jump was measured in the Squat Jump, followed by the Countermovement Jump. After that, the Fv profile was analyzed under both contraction types to assess potential imbalances. The results showed an Fv imbalance of 24.93% during the concentric muscle contraction and 29.71% during the eccentric-concentric muscle contraction. Based on these findings, it is suggested that training should prioritize enhancing strength capabilities while simultaneously addressing Fv imbalances. Reducing theoretical Fv imbalance could serve as a supplementary component of training to improve overall physical. performance.
