Whole Body Muscle Activity during the FIFA 11 + Evaluated by Positron Emission Tomography

Purpose: This study investigated the effect of the FIFA 11+ warm-up program on whole body muscle activity using positron emission tomography. Methods: Ten healthy male volunteers were divided into a control group and a group that performed injury prevention exercises (The 11+). The subjects of the control group were placed in a sitting position for 20 min and 37 MBq of Ffluorodeoxyglucose (FDG) was injected intravenously. The subjects then remained seated for 45 min. The subjects of the exercise group performed part 2 of the 11+for 20 min, after which FDG was injected. They then performed part 2 of the 11+for 20 min, and rested for 25 min in a sitting position. Positron emission tomography-computed tomography images were obtained 50 min after FDG injection in each group. Regions of interest were defined within 30 muscles. The standardized uptake value was calculated to examine the FDG uptake of muscle tissue per unit volume. Results: FDG accumulation within the abdominal rectus, gluteus medius and minimus were significantly higher in the exercise group than in the control group (P,0.05). Conclusion: The hip abductor muscles and abdominal rectus were active during part 2 of the FIFA 11+ program. Citation: Nakase J, Inaki A, Mochizuki T, Toratani T, Kosaka M, et al.
