Cardiovascular Effects of Exercise

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.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 (30 m sprint), flexibility (sit-and-reach test) and vertical jump performance (squat jump).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 favor of the control group for the intervention period and the follow-up (crude β: -0.04 [95% CI: -0.06; -0.01]; -0.03 [95% CI: -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 [95% CI: -0.10; 0.00]; -0.05 [95% CI: -0.10; 0.04]).The present study has shown no short and long-term performance enhancement in sprint, flexibility, agility and jump performance after the FIFA 11+ in male amateur futsal players.
