BACKGROUND: The ability of the FIFA 11+ to enhance performance has demonstrated controversial results. Hence, we examined the short and long-term effects of the FIFA 11+ on performance in male amateur futsal players.
METHODS: Seventy-one male futsal players from six amateur clubs were recruited and randomized to an intervention (n=37, age: 27.0±5.1 years) or a control group (n=34, age: 26.0±5.1 years). The intervention group was submitted to 10-weeks of FIFA 11+ injury prevention program, 2 sessions/week, followed by a 10-week follow-up period, while the control group performed regular futsal warm-ups during the training sessions. During the follow-up period both groups performed only regular warm-ups during their training sessions. Physical performance was assessed by measuring agility (T-test), sprint (30m sprint), flexibility (sit-and-reach test) and vertical jump performance (squat jump).
RESULTS: Differences between groups were found at baseline for training exposure, body mass index, body weight, flexibility and sprint. The results of the effect of the FIFA 11+ on the sit-and-reach test, speed and agility did not show differences pre-post intervention, as well as for the 10-week follow-up. Jump performance, showed a significant difference in favour of the control group for the intervention period and the follow-up [Crude β, -0.04 (-0.06; -0.01); -0.03 (-0.06; -0.00), respectively], however after adjustment for the baseline differences the confidence interval fell out of the range of significance for the intervention and follow-up period [Adjusted β, -0.05 (-0.10; 0.00); -0.05 (-0.10; 0.04)].
CONCLUSIONS: The present study has shown no short and longterm performance enhancement in sprint, flexibility, agility and jump performance after the FIFA 11+ in male amateur futsal players.
