Countermovement jump performance (jump height, peak power output), alongside 15 m sprints, were assessed post-warm-up, and pre- and post-simulated match-play. Core temperature, heart rate, ratings of perceived exertion, and blood glucose and lactate concentrations were measured throughout.ResultsWarm-up-induced core temperature elevations (∼2.3%, +0.85 °C; p < 0.001) were maintained until after the first rewarm-up. Thereafter, core temperature was reduced from post-warm-up values until pre-simulated match-play (∼1.6%, -0.60 °C; p < 0.001), where values were similar to pre-warm-up (37.07 ± 0.24 °C, p = 0.981). Simulated match-play increased core temperature progressively (p ≤ 0.05) but values remained lower than post-warm-up (∼5 min; p = 0.002) until ∼10 min into exercise. From post-warm-up to pre-simulated match-play, sprint times (∼3.9%, +0.10 s, p = 0.003), jump height (∼9.4%, -3.1 cm; p = 0.017), and peak power output (∼7.2%, −296 W; p < 0.001) worsened.
