“…7,16,22 Not all training programs have had significant success in reducing ACL injury rates, and female athletes may not universally experience the same magnitude of landing pattern improvement. For example, Pfeiffer et al 24 recently published the results of a randomized…”

“…The training consisted of a 20-minute, 2-times-per-week plyometric-based exercise program focused on mechanics and alignment of the lower extremity when landing from a jump and deceleration with directional changes when running. 24 Myer and colleagues 20 have recently reported that female athletes who are at high risk for ACL tear, as classified by their large external knee abduction moment during landing from a drop vertical jump (DVJ), were able to substantially reduce their knee valgus moment after 6 weeks of training that included plyometrics instruction and training, core strengthening, balance exercises, resistance training, and speed training. Although the female athletes reduced their external knee valgus moment, they still did not reduce their moments to values similar to their low-risk female counterparts.…”

Purpose The objective of the present randomised controlled trial was to study the effect of a neuromuscular warm-up programme on performance tests in youth female football.Methods Four youth female football teams with players aged 12-16 years were randomised into an intervention group and control group. The intervention was a 15-minute neuromuscular warm-up program carried out twice a week during the 11-week study period.Baseline and follow-up measurements of performance were made indoors and included the star excursion balance test, a countermovement jump test, a triple-hop for distance test, a modified Illinois agility test, and 10 and 20 m sprint tests.Results Fifty-two players (intervention 28; control 24) took part in baseline measurements, and after dropout, 41 players (intervention 23; control 18) were included for analysis. Minor positive changes were seen in the control group compared to the intervention group for a subscore of the star excursion balance test (P < 0.05) and in the modified Illinois agility test (P < 0.05). No improvement was seen in the intervention group from baseline to follow-up. ConclusionsThe study showed that a neuromuscular warm-up programme carried out during 11 weeks did not improve performance in youth female football. This could indicate that the programme does not contain sufficient stimulus to improve performance. A low player attendance at training sessions, and low specificity between exercises in the warm-up programme and the evaluated performance tests may also contribute to the lack of effect.Level of evidence I.

“…Several ACL intervention programs have not been successful in significantly reducing noncontact ACL injury rates in adolescent female athletes [75][76][77][78][79]. It is important to note that some programs did reduce the incidence of lower limb injuries [75], acute knee injuries [78], contact knee injuries [78], and contact combined with noncontact ACL injuries [79].…”

While many anterior cruciate ligament (ACL) prevention programs have been published, few have achieved significant reductions in injury rates and improvements in athletic performance indices; both of which may increase compliance and motivation of athletes to participate. A supervised neuromuscular retraining program (18 sessions) was developed, aimed at achieving both of these objectives. The changes in neuromuscular indices were measured after training in 1000 female athletes aged 13-18 years, and the noncontact ACL injury rate in 700 of these trained athletes was compared with that of 1120 control athletes. There were significant improvements in the drop-jump test, (p < 0.0001, effect size [ES] 0.97), the single-leg triple crossover hop (p < 0.0001, ES 0.47), the t-test (p < 0.0001, ES 0.64), the multi-stage fitness test (p < 0.0001, ES 0.57), hamstring strength (p < 0.0001), and quadriceps strength (p < 0.01). The trained athletes had a significant reduction in the noncontact ACL injury incidence rate compared with the controls (1 ACL injury in 36,724 athlete-exposures [0.03] and 13 ACL injuries in 61,244 exposures [0.21], respectively, p = 0.03). The neuromuscular retraining program was effective in reducing noncontact ACL injury rate and improving athletic performance indicators. OPEN ACCESSSports 2015, 3 57
