20.500.12556/RUL-183013 Hydration and fluid intake in basketball players during training comparison of different age categories There are many studies on basketball players’ hydration in the literature. However, no studies have compared the hydration status of basketball players in different age categories. Therefore, this study aims to compare the hydration status and fluid intake of male basketball players of different age categories during a training session. A total of 70 athletes, actively competing in U14 (n = 30) and U21 (n = 40) teams, voluntarily participated. Urine samples were collected before and after the session to assess hydration status via urine specific gravity (USG). Fluid intake was also individually monitored during the training. Results showed a significant interaction between time and age group in terms of USG (F($_{1,68}$) = 23.72, p < 0.001, η$^2$ = 0.083). While dehydration levels increased in U14 players during the session, U21 players showed improved hydration. The U21 group consumed significantly more fluid (1.16 ± 0.65 L) than the U14 group (0.72 ± 0.50 L; p = 0.003). No significant correlation was found between fluid intake and hydration change in either group. These findings suggest that younger athletes may require more guidance and education regarding proper hydration habits during training. sport team sports hydration body composition fluid intake age groups urine specific gravity basketball šport ekipni športi hidracija telesna sestava vnos tekočine starostne skupine specifična teža urina košarka true false true Angleški jezik Slovenski jezik Članek v reviji 2026-06-01 12:18:34 2026-06-01 12:18:36 2026-06-02 04:34:19 0000-00-00 00:00:00 2025 0 0 9 str. iss. 19, art. 10304 Vol. 15 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.323 2076-3417 10.3390/app151910304 251345155 applsci-15-10304.pdf applsci-15-10304.pdf 1 CF4266CDCB39830BED481B3D370879EC 6b038b5c967a167f60df1b8641543f43faa1fb1d0fcee2ca4992407e73bb5361 90411e3b-5da3-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234795 https://www.mdpi.com/2076-3417/15/19/10304 1 e566dcd6-5da2-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234794 Fakulteta za šport 0 0 0
