| Abstract |
| Background Ankle sprains are the most common sports injury among football players, accounting for approximately 40% of all sports injuries, with a recurrence rate as high as 61%. Over 70% of individuals who sustain an ankle sprain develop chronic ankle instability (CAI). Objectives Compared with non-CAI individuals, those with CAI demonstrate reduced athletic performance, particularly in change-of-direction (COD) movements. This study aimed to examine the acute effects of a FIFA 11+–based peroneal muscle activation (FIFA 11+PMA) warm-up program on COD and forward sprint performance in soccer players with CAI. study design A total of 38 collegiate soccer players with CAI (16 males, 4 females; age: 20.3 ± 0.98 years; height: 176.3 ± 8.70 cm; weight: 68.36 ± 10.46 kg; BMI: 21.97 ± 2.59) participated in this randomised crossover study. Each participant completed two warm-up protocols—standard FIFA 11+ and FIFA 11+PMA—in a randomised order, with at least a 7-day washout period between sessions. The FIFA 11+PMA protocol retained the first and third segments of the standard FIFA 11+ but replaced four exercises in the second segment to emphasise peroneal muscle activation: Elastic Band Ankle Eversion, Bosu-ball Swallow Stance, Bosu-ball Squat, and Left–Right Jump. Immediately after each warm-up, participants performed performance tests, including the Eight-hop and Illinois Agility Tests for COD ability, and 20 m sprint tests with and without the ball for forward sprint performance. Paired-sample t-tests were used to compare post-warm-up performance between conditions. Results Compared to the standard FIFA 11+, the FIFA 11+PMA warm-up resulted in significant improvements in both COD and sprint performance. Participants demonstrated faster times in the Eight-hop Test (p < 0.05) and Illinois Agility Test (p < 0.05), as well as reduced sprint times in the 20 m sprint with and without the ball (p < 0.05). Conclusions The FIFA 11+PMA warm-up was more effective than the standard FIFA 11+ in enhancing change-of-direction and forward sprint performance among collegiate soccer players with CAI. Incorporating targeted peroneal activation exercises into existing warm-up routines may improve neuromuscular readiness and movement efficiency, potentially reducing ankle injury risk in soccer players with instability. |
