Effect of 12 weeks of pliometry on young rugby players' physical parameters (U14-16) in Ivory Coast

BACKGROUND: This study explores the effects of a 12-week plyometric training program on physical parameters such as speed, vertical jump ability, and power among young rugby players from the Treichville Biafra Olympique club in Côte d’Ivoire. Plyometric training, despite its potential to enhance sports performance, is not widely integrated into the routines of young athletes in rugby - a contact sport that demands both strength and speed. This research aims to assess the impact of this training method on U14 and U16 players, considering age and gender differences.METHODS: A total of 72 young rugby players participated undergoing plyometric training. Performance was measured using three standardized tests: the 40-m sprint for speed, the Sargent Test for vertical jump ability, and the standing long jump for power. RESULTS: The plyometric training program significantly improved specific physical parameters. U14 and U16 boys showed notable gains in speed and power, though results for vertical jump ability were inconsistent. U16 girls experienced significant speed improvements, whereas U14 girls did not demonstrate progress in vertical jump ability. Additionally, U16 boys exhibited remarkable power gains, but these improvements were not observed among girls. CONCLUSIONS: The 12-week plyometric training program positively influenced speed and power, but its effects varied across age and gender groups. These findings underline the importance of tailoring training programs to the unique needs of different subgroups, ensuring they are age- and gender-appropriate to maximize effectiveness.
