| Hammes et al., 2014 [22] | Randomized Clinical Trial | 265 | Intervention Group (n=146) Age: 45 ± 8 years old. Group Control (n=119) Age: 43 ± 6 years old. Gender: Male |
Duration: 9 months Frequency: 1 time a week |
No significant difference was found between the Intervention Group and the Control Group in the global incidence of lesions (IRR: 0.91 (0.64-1.48), p = 0.89) Only serious injuries reached significance Statistic with higher incidence in the Group Control (IRR: 0.46 (0.21-0.97), p = 0.04). |

The FIFA11 + program significantly reduced the overall injury rate in the Intervention Group by 41% [RR = 0.59 (95% CI: 0.40-0.86; p = 0.006)] and lesions in lower limbs 48% [RR = 0.52 (95% CI: 0.34-0.82; p = 0.004)]. The FIFA11 + program is effective in reducing injury rates in young male soccer players. |
| Silvers-Granelli et al., 2015 [26] | Randomized Clinical Trial | 1525 | Intervention Group (n=675) Group Control (n=850) Age: 18-25 Gender: Male |
Duration: 5 months Frequency: 1 time a week |
In group Control, 665 injuries (mean ± SD, 19.56 ± 11.01) were reported by 34 teams, which corresponded to an incidence rate (IR) de 15.04 lesions per 1000 exposure time. In the Intervention Group, 285 lesions (mean ± SD, 10.56 ± 3.64) were reported by 27 teams, which corresponded to an IR of 8.09 lesions per 1000 exposure time. Total days lost due to injury were significantly higher for group control (Mean ± SD, 13.20 ± 26.6 days) than for the Intervention Group (mean ± SD, 10.08 ± 14.68 days) (P = 0.007). There was no difference for the loss of time due to an injury based on the field type (P = 0.341). FIFA11 + significantly reduced injury rates by 46.1% and decreased injury time loss, 28.6% in competitive male collegiate football player (rate ratio, [95% CI 49-, 59]), 54, P <0.0001. |
| Soligard et al., 2008 [24] | Randomized Clinical Trial | 1892 | Intervention Group (n=1055) Group Control (n=837) Age 15,4±0,7 Gender: Female |
Duration: 8 months Frequency: 2 a 5 times a week |
In the intervention group, there was a significantly lower risk of injury in general (RR = 0.68, 95%; CI 0.48-0.98), lower risk of overuse / fatigue injuries (RR = CI 0.47, 95% 0.26-0.85) and lower risk of serious injury (RR = 0.55, 95% CI 0.36-0.83) compared to the control group). The FIFA11 + program is effective in reducing injury rates in young female gender football players. |
| Steffen et al., 2013 [25, 27] | Randomized Clinical Trial | 226 | Intervention Group (n=146) Group Control (n=80) Age:13-18 years old Gender: Female |
Duration: 4.5 months Frequency: 2-3 times a week |
Compared to players with low adherence, players with high adherence to FIFA 11+ had a 57% lower risk injury (RR = 0.43; 95% CI 0.19-1.00). However, after adjustment for covariables, this difference between groups was not statistically significant (RR = 0.44; 95% CI 0.18-1.06) |
| Steffen et al., 2008 [23] | Randomized Clinical Trial | 2020 | Intervention Group (n=1073) Group Control (n=947) Age 13 – 17 years old Gender: Female |
Duration: 8 months Frequency: 1 time a week | There was no difference in the overall lesion rate between the intervention (3.6 lesions / 1000 h, CI: 3.2-4.1) and group Control (3.7, Cl 3.2-4.1; RR 51.0, CI 0.8-1.2, P 50.94) or in the incidence of any type of injury. |
