Resumen

Objective: To compare the physical performance and official match demands of soccer players following a warm-up session that involved small-sided games with weighted vests of varying loads. Equipment and methods: This study involved fifteen highly trained male soccer players (age: 17.8 ± 0.5 years; height: 173.4 ± 6.3 cm; body mass: 66.1 ± 7.4 kg; training experience: 10.5 ± 1.3 years) from the same team who competed in the national league for their age group. Their regular training schedule included four sessions and one competitive match per week. The participants completed three different warm-up protocols without weighted vest, with 5%, and 10% body mass weighted vest) during the intervention, following a counter-balanced design. After each protocol, players completed the triple hop jump test and the modified change-of-direction test. Also, the physical demands, including distance, high-speed distance, distance in acceleration and deceleration, and peak velocity, were assessed at three intervals: 0–15, 15–30, and 30–45 min of the first half of official matches. Results: The one-way repeated measures ANOVA revealed that the performance in the triple jump test and T-test significantly improved (P < 0.01) after the protocol that included a small-sided game with a weighted vest at 5% of body weight compared to the protocol without a weighted vest. The peak velocity was higher after the protocol using vests at 5% of body weight than after the protocol without weighted vests in the intervals 0–15 (P < 0.01), 15–30 (P < 0.01), and 30–45 min (P < 0.05). Players covered more high-speed distance after the protocol with a weighted vest at 5% of body weight than after the warm-up without a weighted vest at 0–15 (P < 0.05) and 15–30 min (P < 0.01). Both acceleration and deceleration distance during the 30–45 min interval were significantly greater (P < 0.01) after the protocol using a weighted vest at 10% of body weight than after the protocol using a 5% body weight vest and the protocol without a weighted vest. In conclusion, a loaded warm-up with a 5% body mass enhances acute performance in horizontal jump, change-of-direction ability, and peak velocity compared to an unloaded warm-up. Incorporating a specific warm-up with a weighted vest at 5% body mass proves effective, particularly in the initial 30 min of the match.
