Performance differences between female youth handball players selected for national teams and non-selected peers are often linked to strength, speed, and power. This study aimed to compare the conditioning capacities and body composition of national and non-national youth handball players. The sample included 36 female players (17.13 ± 1.75 years), 18 national and 18 position-matched non-national players. Anthropometry, sprint and change in direction ability, vertical jump, upper- and lower-body strength, aerobic capacity, and body composition were assessed using standard tests and bioimpedance analysis. For normally distributed variables, an independent-samples t-test was applied, while for variables that did not meet the normality assumptions, the Mann–Whitney U test was used. Cohen’s d was used to assess effect size. National team players showed significantly greater jump height (p < 0.001, d = 1.408), higher relative peak power (p < 0.001, d = 1.644), and faster 20 m sprint times (p = 0.004, d = −1.037). No significant differences were found in body composition or the other measured parameters, although a moderate Yo-Yo IRL1 effect size suggests a potential practical advantage in aerobic capacity for national team players. These results indicate that explosive power and linear speed are key discriminators for youth national-team selection.

No significant differences were found in body composition or the other measured parameters, although a moderate Yo-Yo IRL1 effect size suggests a potential practical advantage.

Background/Objectives: The aim of this study was to describe seasonal trends in match-average External Load (EL) variables across three (2022/23, 2023/24, 2024/25) consecutive competitive seasons in a Hungarian professional second-division soccer team (Gyirmót FC Győr), using the Catapult Vector S7 Global Navigation Satellite System (GNSS). Specifically, Average Distance (AD; m), Average Player Load^TM (PL; AU), and Acceleration–Deceleration Efforts (>2 m·s⁻²) (ADE) were examined. The study aimed to provide descriptive reference values and characterize seasonal variation in match EL demands within a professional second-division context. Methods: A descriptive seasonal comparison was conducted based exclusively on aggregated match average EL values. The unit of analysis was the match, with each match contributing one aggregated value per variable derived from players who completed the full match. A total of 94 matches were included (2022/23: N = 38; 2023/24: N = 29; 2024/25: N = 27); matches with red cards were excluded. EL data were collected using a 10 Hz Catapult Vector S7 GNSS. Results: The median AD decreased continuously from the 2022/23 season (10.210 m) to the 2024/25 season (9.795 m). The median PL decreased from 1002 (2022/23 and 2023/24) to 846 in the 2024/25 season. The median ADE decreased from 220.8 (2022/23) to 199.0 (2024/25). Conclusions: Lower values were observed across match EL variables, with the most pronounced reduction in PL. These findings provide descriptive reference values and may support the interpretation of seasonal variation in match EL demands in professional second-division soccer.

Background/Objectives: Soccer is a team sport that places significant physical demands on players. Players cover greater distances at higher speeds, and the number of high-intensity movements is increasing. The present study analyzed the locomotor and mechanical variables of Hungarian second division professional soccer players over three seasons (2022/23, 2023/24, 2024/25), using Catapult Vector S7 and processing data from 94 matches. Methods: We included 94 matches in the study (2022/23: N=38; 2023/24: N=29; 2024/25: N=27), in which only the data of players who played the entire matches were analyzed, excluding red card matches. Performance data was collected using Catapult Vector S7 10 Hz GNNS system. Results: The median average distance covered decreased continuously from the 2022/23 season (10.210 m) to the 2024/25 season (9.795 m) (H (2) = 14.14, p<0.001, Rank ε² = 0.152, medium effect size). The median Player Load decreased from 1002 (2022/23 and 2023/24) to 846 in the 2024/25 season (H (2) = 55.64, p<0.001, Rank ε² = 0589, very large effect size). The median acceleration-deceleration effort (Accel + Decel) decreased from 220.8 (2022/23) to 199.0 (2024/25) (H (2) = 26.81, p<0.001, Rank ε² = 0.288, effect size). Conclusion: There was a significant seasonal decrease in match load variables. The most pronounced decrease occurred in the mechanical indicator. These results may provide useful insights into the physical demands of matches.
