| Abstract | This study aimed to compare the effect of two different re- warm -up (RW) protocols on selected performance outcomes in professional soccer players. Thirteen male professional soccer players (age: 21.1±0.8 years; height: 1.77±0.04 m; weight: 67.7±6.3 kg; BMI: 22.3±1.8 kg×m2; VO2max: 48±1.7 ml×kg-1×min-1) were recruited to take part in this study. In a randomized counterbalanced crossover fashion, participants completed a simulated substitute soccer routine involving a 20-minute warm-up and 40- minute passive restfollowed by either a 2- minute high- intensity interval RW (HI-RW) at 90% VO2max interspersed with 30% VO2max, or a 3-minute continuous low-intensity RW (LO-RW) at 30% VO2max, both performed on a cycle ergometer. Countermovement jump (CMJ) flight time with simultaneous assessment of quadriceps muscle activation using electromyogram (EMG) activity, running anaerobic sprint test (RAST) indices, and ratings of perceived exertion (RPE) were measured after the 20-minute warm-up (pre) and post RW timepoints. No significant condition x time interaction was observed for CMJ flight time (p = 0.465) or quadriceps EMG activity in the rectus femoris (p = 0.263), vastus lateralis (p = 0.129), and vastus medialis (p = 0 .262). Similarly, there was no significant interaction effect found for RAST indices (all p>0.05) or RPE (p = 0.355). It is concluded that both HI-RW and LO-RW protocols exerted comparable effects on the measured physiological and performance parameters in soccer players. However, due to the practical advantage of using a 2-minute HI-RW due to the protocol being more time efficient, and thus, more ecologically valid during substitution scenarios, completion of a HI-RW may be considered a more suitable RW option for in-game substitutes. |
