abstract="OBJECTIVE: To investigate acute effects of a single bout of football specific neuromuscular injury preventive warm-up on potential anterior cruciate ligament (ACL) re-injury risk factors during anticipated and unanticipated jump-landings. <br><br>DESIGN: Crossover. <br><br>METHODS: Fourteen participants (mean ± SD age, 23.4 ± 4.1 years) 6-24 months after ACL reconstruction performed the Prevent Injury and Enhance Performance (PEP) and bicycle ergometer warm-up in a randomised sequence. Washout phase was one week. Countermovement jumps with anticipated and unanticipated single-leg-landings were assessed. Decision-making quality was measured using landing error count. <br><br>RESULTS: No carry-over effects occurred (p > 0.05). The unanticipated task produced significantly higher peak ground reaction forces (Δ+4%, F((11)) = 3.46, p < 0.001, eta(2) = 0.21) after PEP warm-up compared to ergometer warm-up. A lower number of decision (Δ+12%, F ((5)) = 17.1, p < 0.001, eta(2) = 0.57) and cumulated (Δ+15%, F ((3)) = 17.2, p < 0.001, eta(2) = 0.57) errors were recorded during the unanticipated condition following PEP compared to ergometer warm-up. <br><br>CONCLUSIONS: Evaluating unanticipated jump-landing ability prior to return to sports clearance may provide information on potential re-injury risk factors. PEP warm-up may be superior to bicycle ergometer warm-up at improving unanticipated decision-making quality among athletes cleared to return to sports.<p /> <p>Language: en</p>",
