    Functional movement screening (FMS) is a test developed to evaluate the fundamental movement patterns underlying both sports performance and injury risk. This study aims at evaluating the relationships between FMS test scores and strength and balance performance in young male athletes. Male athletes (n = 41, mean age 13.5 ± 1.7 years) interested in team sports participated in the study voluntarily. FMS scores, dynamic balance, static balance and strength values of the participants were determined. Shapiro-Wilk test was applied to determine if the data were normally distributed, Pearson’s correlation coefficient analysis was used measure linear correlation, and Spearman’s rank correlation coefficient (ρ) was determined to measure the strength and direction of correlation between variables. Significant differences ranged between p = 0.01 and p = 0.05. As a result of the analyses, a positive low-level relationship for the balance measures was found between the total. FMS score and the right postero-medial (p = 0.042), and right leg composite (p = 0.30), left leg composite (p = 0.026) of the Y balance subtests while no relationships were identified in other parameters (p > 0.05). For the strength masures, a positive low-level relationship was detected between the FMS score and back strength (p = 0.016), while no relationship was found between the other strength parameters (p > 0.05). For balance and strength parameters, a moderate negative relationship was found between the FMS score and the left leg flamingo test (p = 0.009). Also according to regression analysis that the predictive power of independent variables on FMS scores is quite low. In general, it is seen that the autocorrelation between the dependent variable and predictor variables is at an acceptable level (1.768 < Durbin-Watson < 2.196). As a result, FMS scores in this athlete sample were associated with dynamic balance, static balance and strength performance.

    Effects of different pre-exercise strategies on jumping performance in female volleyball players
    (Edizioni Minerva Medica, 2024-12) KESKİN, Kadir; AKÇAY, Neslihan; ÖZMEN, Tarık; CONTARLI, Nurcan; YILDIZ, Kerem C.; SOFUOĞLU, Cem; KAMİŞ, Okan; ROLNICK, Nicholas; de QUEIROS, Victor S.; MONTOYE, Alexander
    BACKGROUND: The present study aimed to compare different pre-exercise strategies on jumping performance in female volleyball players. METHODS: Fifteen healthy female volleyball players (age=18±0.6 years; training experience = 7.3±1.4 years; height = 164.8±5.4 cm; body mass = 57.2±8.1 kg) volunteered to participate in the study. Three different pre-exercise conditions (5 repetition maximum knee extension, electromyostimulation [EMS] and ischemic preconditioning [IPC]) were applied to the subjects and compared to a control condition performing a standardized warmup. Subjects performed the squat jump and 15 sec repeated countermovement jumps following a rest period. Measures associated with jumping performance were collected and compared between conditions. Rating of perceived exertion was also collected after each performance test. RESULTS: No pre-exercise condition outperformed a standardized warm-up on inducing improvements in jumping performance and in fact, EMS and IPC conditions resulted in performance decrements compared to control (P<0.05). CONCLUSIONS: We conclude that a standardized warm-up is enough to induce improvements in jumping performance in female volleyball players. Future research should examine alternative strategies alongside standardized warm-up to determine how best to prepare for jumping and related sport-specific tasks in female volleyball players.

    Effects of Different Intensities Post-Activation Performance Enhancement Protocols on Repeated Sprint Ability in Male Soccer Players: A Randomised Crossover Trial
    (MDPI AG, 2024-11-06) Akgül, Mustafa Şakir; Tohănean, Dragoș Ioan; Akçay, Neslihan; Păun, Laurian Ioan; Çetin, Tuğba; Uysal, Hüseyin Şahin; Alexe, Cristina Ioana
    (1) Background: Post-activation performance enhancement (PAPE) protocols using heavy resistance preloading may improve RSA, yet optimal preloading intensity for amateur players is still unknown. This study investigated the effects of two PAPE protocols using different preloading intensities (85% and 90% of 1RM back squat) on RSA. (2) Methods: A double-blind, randomized, two-period crossover design was used, and 18 amateur male players were included in the study. RSA was assessed using a 6 x 35m sprint protocol with 10-second rest intervals (RAST). (3) Results: While the main effect of time significantly (p=0.01, η²=0.71) influenced performance decline across all groups, there was no significant (p=0.65, η²=0.01) interaction between time and condition. Individual responses to PAPE varied, highlighting the importance of individual differences. Interestingly, the BS85% group exhibited a less pronounced decline in performance compared to the control group, while the BS90% group only showed significant differences in three sprint levels. (4) Conclusions: Our findings suggest that a lower preload of 85% of 1RM may be as adequate as a higher preload of 90% of 1RM in enhancing RSA in amateur soccer players. These results may indicate a potential fatigue-delaying effect of PAPE protocols and emphasize the importance of individualized approaches for optimizing PAPE strategies.
