| Summary: | This interventional controlled study investigated the effects of Olympic weightlifting (OWL) on strength, power, and speed in adolescent rugby union players. Under-17 rugby union players were divided into two groups (WLG and CON) [n: 46, age: 15.4 (0.5) years, stature: 175 (6.1) cm, body mass: 73.7 (15.6) kg]. The WLG participated in an 8-week OWL program. Pre- and post-intervention assessments measured countermovement jump height, 10m and 30m sprint times, and a 5RM back squat.
Results showed no substantial differences between groups at pre- and post-intervention for strength, power, and speed. Strength significantly improved for both groups from pre-to-post. In addition, the WLG demonstrated a greater rate of strength development in comparison to the CON group (MLE = 7.30, SE = 1.83, 95%CI = [3.65, 10.94], t = 3.99, p < 0.001). Power did not present substantial changes between pre and post for both groups. Speed performance decreased from pre to post for both WLG and CON (p < 0.001). Nonetheless, smaller decreases were observed in the WLG for 10m (+0.05 vs +0.09 sec) and 30m (+0.12 vs +0.20 sec) sprints. Furthermore, anthropometrics (i.e., stature and body mass) proved to be important factors contributing to strength, power, and speed development.
The study found no clear evidence to support the benefit of OWL in developing strength, power, and speed in adolescent athletes without prior experience with these exercises. However, OWL may enhance absolute strength gains and mitigate speed performance declines in youth rugby players. Stature and body mass significantly affected these performance metrics, highlighting the need to consider individual differences and developmental changes. Continuous assessment and careful adjustment of training programs are crucial during adolescence to account for variations in stature and body mass.
