| Summary, etc. | Cette étude visait à comparer la composition corporelle et les performances physiques entre les joueurs de rugby U-17 et U-19 (avants et arrières) et à examiner les corrélations entre la composition corporelle, la force relative, les sauts et les performances de sprint dans les deux positions de jeu. Cinquante-deux joueurs de rugby adolescents masculins (moyenne ± ET : âge, U-17 : 16,2 ± 0,6 et U-19 : 18,09 ± 0,9 ans) ont participé à l’étude. Les joueurs ont effectué des tests anthropométriques, de composition corporelle (∑3 plis cutanés [SF], de graisse corporelle [BF] et de masse maigre [LM]), de saut vertical, de sprint de 30 m et de squat à répétition maximale (1RM-SQ). Des différences significatives ont été observées pour la masse corporelle (BM) et les variables de composition corporelle entre les positions de jeu pour les deux catégories ( p : 0,05 à < 0,001 ; ES > 0,72). Les avants U-17 ont montré des performances significativement différentes dans toutes les variables par rapport aux arrières U-19 ( p : 0,05 à < 0,001 ; ES > 1,08). De même, les avants U-17 ont montré une force relative plus faible ( p : 0,05–0,095; ES > 1,66) et des temps de sprint de 30 m plus élevés ( p < 0,024 ; ES > 0,57) par rapport aux avants U-19 et aux arrières U-17. Globalement, pour les dos, BM et LM étaient significativement associés à toutes les variables de performance ( r : −0,72 à 0,50 ; p < 0,05). À l’inverse, pour les avants, BF et SF étaient significativement corrélés avec la hauteur de saut vertical et les temps de sprint ( r : −0,62 à 0,52 ; p < 0,05). Des différences nettes existent entre les arrières et les attaquants quelle que soit la catégorie d’âge, alors qu’aucune différence n’a été observée entre les arrières U-17 et U-19. Les résultats actuels suggèrent que les praticiens devraient surveiller différentes variables de composition corporelle en raison de l’ampleur des associations observées avec les capacités de sprint et de saut. |
| 520 ## - SUMMARY, ETC. | |
| Summary, etc. | This study aimed to compare body composition and physical performance between U-17 and U-19 rugby players (forwards and backs), and examine the correlations among body composition, relative strength, jump, and sprint performance in both playing positions. Fifty-two male adolescent rugby players (mean ± SD: age, U-17: 16.2 ± 0.6 and U-19: 18.09 ± 0.9 years) participated in the study. Players performed anthropometric, body-composition (∑3 skinfolds [SF], body fat [BF] and lean mass [LM]), vertical jump, 30-m sprint, and squat one-repetition maximum (1RM-SQ) tests. Significant differences were observed for body mass (BM) and body composition variables among playing positions for both categories ( P: 0.05 to < 0.001; ES > 0.72). U-17 forwards showed significantly different performance across all variables when compared to U-19 backs ( P: 0.05 to < 0.001; ES > 1.08). Likewise, U-17 forwards showed lower relative strength ( P: 0.05–0.095; ES > 1.66) and higher 30-m sprint times ( P < 0.024; ES > 0.57) when compared to U-19 forwards and U-17 backs. Overall, for the backs, BM and LM were significantly associated with all performance variables ( r: −0.72 to 0.50; P < 0.05). Conversely, for the forwards, BF and SF were significantly correlated with vertical jump height and sprint times ( r: −0.62 to 0.52; P < 0.05). Clear differences exist between backs and forwards irrespective of the age category, whilst no differences were observed between U-17 and U-19 backs. The present results suggest that practitioners should monitor different body-composition variables due to the magnitude of associations observed with sprinting and jumping abilities. |
