Objectives To identify the intrinsic risk factors of non-contact strains in the hamstrings and quadriceps muscles of professional soccer players via a cohort prospective design. Methods A total of 100 professional soccer players (aged 19.4–27.8 years) from four professional teams underwent a composite musculoskeletal assessment at preseason. Intrinsic risk factors included dichotomies of asymmetries in muscle strength, flexibility, proprioception, anthropometry and knee joint stability, and of… 

Potential prognostic factors for hamstring muscle injury in elite male soccer players: A prospective study

Regression analysis revealed that age, Nordic hamstring strength test, previous injury history, and isokinetic concentric torque at 240°/sec could determine hamstring injuries by 25.9%, with no other significant predicting risk factors.

Prevalence of Hamstring Strain Injury Risk Factors in Professional and Under-20 Male Football (Soccer) Players.

Most football players present multiple risk factors for sustaining an HSI, but the teams should also be aware of deficits in flexibility, core stability, functional movements, and hamstring fascicle length.

Short biceps femoris fascicles and eccentric knee flexor weakness increase the risk of hamstring injury in elite football (soccer): a prospective cohort study

The greater risk of a future HSI in older players or those with a previous HSI is reduced when they have longer BFlh fascicles and high levels of eccentric strength.

Intrinsic Risk Factors of Noncontact Ankle Sprains in Soccer

Functional strength asymmetries of the ankle flexors and increased body mass index and body weight raise the propensity for ankle sprains in professional soccer players.

A novel multifactorial hamstring screening protocol: association with hamstring muscle injuries in professional football (soccer) – a prospective cohort study

The present results support the potential relevance of additionally including frequent F0 testing for HMI risk reduction management and future studies should explore whether improving F0 is relevant within a multifactorial HMIrisk reduction approach.

Muscle strength characteristics of the hamstrings and quadriceps in players from a high-level youth football (soccer) Academy

New evidence is provided that the isometric H/Q ratio reduces with advancing age during adolescence which may have important implications for junior athlete development and long-term injury prevention in football.

A comprehensive strength testing protocol offers no clinical value in predicting risk of hamstring injury: a prospective cohort study of 413 professional football players

The clinical value of isolated strength testing is limited, and its use in musculoskeletal screening to predict future hamstring injury is unfounded.

The lumbar erector spinae could play a major role in the pathophysiology (and reoccurrence) of HSI due to its function to control the forward flexion of the trunk and to maintain an adequate vertebral position.

Eccentric Knee Flexor Strength and Risk of Hamstring Injuries in Rugby Union

Previous HSIs and between-limb imbalance in eccentric knee flexor strength were associated with an increased risk of future HSIs in rugby union, and the rationale for reducing imbalance, particularly in players who have suffered a prior HSI, is supported.

Results indicate that soccer players with an increased tightness of the hamstring or quadriceps muscles have a statistically higher risk for a subsequent musculoskeletal lesion.

The mixed ratio eccentric hamstring-to-concentric quadriceps lower than 0.6 identify a previous hamstring injury despite the resumption of competitive soccer, but this ratio and the others isokinetic studied parameters do not predict a recurrence or a new hamstring muscle injury.

A Prospective Study of Overuse Knee Injuries Among Female Athletes With Muscle Imbalances and Structural Abnormalities.

The presence of genu recurvatum and an H: Q ratio below normal range was associated with an increased prevalence of overuse knee injuries among female collegiate athletes and further investigation is needed to clarify which preseason screening procedures may identify collegiate athletes who are susceptible to over use knee injuries.

THE RELATIONSHIP BETWEEN PRESEASON RANGE OF MOTION AND MUSCLE STRAIN INJURY IN ELITE SOCCER PLAYERS

Screening of flexibility for soccer players should be conducted during preseason, and flexibility training should be prescribed to players with reduced ROM to lower the risk of developing a muscle strain injury.

The injury rate was not different compared to male soccer, but knee injuries were more common, which is in accordance with previous studies, and none of the risk factors identified is easily applicable for future intervention studies in the attempts to reduce the injury rate in female soccer.

The avoidability of soccer injuries.

71% of the injuries proved to be explicable by and associated with player factors, equipment, playing ground, or rules, and 63% of players had tight muscles.

There was a correlation between preseason decreased hip ROM and occurrence of adductor strain and their hip ROM increased to near pre-injury levels once the subjects were able to resume playing soccer.

The results indicate that addition of specific preseason strength training for the hamstrings – including eccentric overloading – would be beneficial for elite soccer players, both from an injury prevention and from performance enhancement point of view.
