Reduction In Injury Incidence Research Articles

The FIFA 11+ injury prevention program reduces the incidence of lower extremity injuries in football players: a systematic review and meta-analysis.

The FIFA 11+ preventive program is designed to reduce the incidence of injury in sports. However, to gain a better understanding of its effect a systematic review and meta-analysis is needed. The current review aims to investigate the effect of the FIFA 11+ preventive program on injury incidence among male and female football players. This study used Scopus, PEDro, SPORTDiscus, and ProQuest as data sources. The initial selection of the studies, thorough assessment of the tile, and abstract. Extraction of the necessary study data was conducted by two independent researchers. Another two independent researchers assessed the quality of each included study against 39 used criteria. These criteria were combined from several popular quality assessment scales. The incidence of injuries measured in the lower extremities in football players after addressing the FIFA11+ was the outcome of interest. This review included 12 trials of variable methodological quality from which 10 trials were selected for the meta-analysis. In general, the FIFA11+ program showed a significant reduction (P<0.1) in lower limb injury incidence for male young and adults in comparison to other programs. However, evidence of its effectiveness in females is lacking and more studies are needed. The FIFA 11+ program is recommended to be used and implemented as a preventive strategy in males. Although, the result showed a significant reduction in injury incidence in adult males, heterogeneity between studies is high which may reduce the generalizability of the results. More studies are needed to investigate the effect of the FIFA 11+ program on females.

Balance Training Enhances Motor Coordination During a Perturbed Sidestep Cutting Task

Study Design Controlled laboratory study. Background Balance training may improve motor coordination. However, little is known about the changes in motor coordination during unexpected perturbations to postural control following balance training. Objectives To study the effects of balance training on motor coordination and knee mechanics during perturbed sidestep cutting maneuvers in healthy adults. Methods Twenty-six healthy men were randomly assigned to a training group or a control group. Before balance training, subjects performed unperturbed, 90° sidestep cutting maneuvers and 1 unexpected perturbed cut (10-cm translation of a movable platform). Participants in the training group participated in a 6-week balance training program, while those in the control group followed their regular activity schedule. Both groups were retested after a 6-week period. Surface electromyography was recorded from 16 muscles of the supporting limb and trunk, as well as kinematics and ground reaction forces. Motor modules were extracted from electromyography by nonnegative matrix factorization. External knee abduction moments were calculated using inverse dynamics equations. Results Balance training reduced the external knee abduction moment (33% ± 25%, P<.03, ηp2 = 0.725) and increased the activation of trunk and proximal hip muscles in specific motor modules during perturbed cutting. Balance training also increased burst duration for the motor module related to landing early in the perturbation phase (23% ± 11%, P<.01, ηp2 = 0.532). Conclusion Balance training resulted in altered motor coordination and a reduction in knee abduction moment during an unexpected perturbation. The previously reported reduction in injury incidence following balance training may be linked to changes in dynamic postural stability and modular neuromuscular control.

The epidemiology of shoulder injuries in Rugby Union Football

Background Shoulder injuries are a significant risk in rugby union football. However, the aetiology and the risk factors associated with shoulder injuries are not well understood. Objective To analyse the incidence and risk factors for shoulder injuries in rugby union football. Design A prospective shoulder injury study was carried out in 2009 using a recursive injury model framework. Setting Community level adult male rugby union players. Participants 75 players at the start and 54 players at the end. Assessment of risk factors The effects of player size, age, injury history and usage of shoulder padding were assessed. Main outcome measurements Shoulder injury incidence rate (IIR). Performance on shoulder assessments using the Constant Score Protocol was measured pre-, mid- and end-season. Weekly training and shoulder impairment was measured. Results A total of 1138.1 player participation hours (pph) were recorded. The overall shoulder IIR was 4.4 injuries per 1000 pph with an average severity of 1.0 missed game. Previous injury and shoulder pads were the main observed intrinsic and extrinsic injury risk factors, respectively. An IIR of 3.5/1000 pph were recorded in players with no history of shoulder injury in the last 3 years (80%). There was a non-significant reduction in injury incidence for players wearing shoulder pads during a match. The tackle has been identified as the intrinsic factor that contributed to 67% of the total time loss to injury. Shoulder pain and impairment were reported by 41% of the players throughout the season but none caused the players to miss any games. Conclusion A recursive injury model was applied however shoulder pain and impairment did not appear to be correlated with injury risk. Recursiveness may not be relevant to the shoulder injuries observed in this cohort. Pre-season screening and appropriate rehabilitation may prevent repeat shoulder injury.

Balance And Strength Changes Following Injury Prevention Protocol In Female Soccer Players

The prevention of sports injuries is characterised by a wide spectrum of approaches with multimodal programs most often advocated, evaluated based on epidemiology but typically failing to clarify which aspect of the intervention program contributed to the reduction in injury incidence. PURPOSE: To quantify the affects of a multimodal injury prevention program previously shown to reduce injury incidence. METHODS: Female collegiate soccer players (n=9) completed the F-MARC 11 injury prevention program in addition to their soccer training over a duration of 6 weeks, whilst an age and training-age matched control group (n=9) completed an equivalent amount of soccer training. Pre- and post-intervention, all players were assessed for isokinetic strength of the knee flexors and extensors in both concentric and eccentric mode at speeds of 1.05, 3.14 and 5.23 rad·s-1, and dynamic posturography using sensory organisation and unilateral sway tests. Between group comparisons were made using repeated measures ANOVA, with significance accepted at p≤0.05. RESULTS: Post-intervention, the F11 group displayed a significant increase in the somatosensory and vestibular contributions to balance during the sensory organisation test. The F11 group also displayed a significant post-intervention decrease in sway velocity during a unilateral stance test, for both eyes open and eyes closed conditions. No changes were observed for the control group. There was no change in peak concentric or eccentric torque for either knee flexors or extensors post-intervention, irrespective of movement speed. There was however a significant change in the angle of peak torque for eccentric knee flexors at the slowest test speed. The control group showed no changes in isokinetic parameters. CONCLUSION: The F11 injury prevention program created a change in the relative contributions to dynamic balance, with an increase in both the somatosensory and vestibular ratios, and no change in the visual ratio. Whilst peak torque was unaffected, there was evidence of a shift in the angle of peak eccentric hamstring torque at the slowest test speed post-intervention. Injury reduction might therefore be attributed to those exercises involving dynamic single-legged balance, enhancing movement control rather than maximal strength.

The Effectiveness of a Balance Training Intervention in Reducing the Incidence of Noncontact Ankle Sprains in High School Football Players

Background A high body mass index and previous ankle sprains have been shown to increase the risk of sustaining noncontact inversion ankle sprains in high school football players. Hypothesis Stability pad balance training reduces the incidence of noncontact inversion ankle sprains in football players with increased risk. Study Design Cohort study; Level of evidence, 2. Methods Height, body mass, history of previous ankle sprains, and current ankle brace/tape use were documented at the beginning of preseason training in 2 high school varsity football teams for 3 consecutive years (175 player-seasons). Players were categorized as minimal risk, low risk, moderate risk, and high risk based on the history of previous ankle sprain and body mass index. Players in the low-, moderate-, and high-risk groups (ie, any player with a high body mass index and/or a previous ankle sprain) were placed on a balance training intervention on a foam stability pad. Players balanced for 5 minutes on each leg, 5 days per week, for 4 weeks in preseason and twice per week during the season. Postintervention injury incidence was compared with preintervention incidence (107 players-seasons) for players with increased risk. Results Injury incidence for players with increased risk was 2.2 injuries per 1000 exposures (95% confidence interval, 1.1-3.8) before the intervention and 0.5 (95% confidence interval, 0.2-1.3) after the intervention (P < .01). This represents a 77% reduction in injury incidence (95% confidence interval, 31%-92%). Conclusion The increased risk of a noncontact inversion ankle sprain associated with a high body mass index and a previous ankle sprain was eliminated by the balance training intervention.
