The modifiable factors are body mass, decreased adductor muscle strength, decreased hip abduction range, total hip rotation range, and adductor:abductor strength ratio (ADD:ABD). Risk factors associated with the development of groin injuries are classified as modifiable and non-modifiable.
TWO KNEE SLIDE SOCCER PROFESSIONAL
Previous literature indicated 56% of the pre-season period players are at risk of muscle strength imbalances for knee flexors (KF) or extensors (KE) concerning the knee function, professional soccer level practice, and competition as critical factors for asymmetries. Also, strength asymmetry seems desirable for improving performance in soccer-related abilities, once was shown to account for better kicking performance with the dominant limb (D). Soccer-specific actions provide the unilateral overuse of lower limbs in almost all passing/receiving, kicking, and cutting skills and soccer players are more effective in unilateral strength training exercises than athletes who frequently perform bilateral activities. Strength differences between legs (bilateral strength asymmetries) and between muscle groups (agonist-antagonist relationship) have been reported in athletes. Soccer has a high injury rate and percentage, where the three most commonly injured body segments/joints, for male players, are the ankle (20%), the thigh (17%), the knee (15%), and the hip/groin (6%). Muscle strength is crucial for performance and injury prevention. Soccer as increased match-play physical demands due to short between-match recovery periods and high neuromuscular demands (e.g., a larger number of high-intensity running actions, acceleration/deceleration requirements, changes of direction, and jumping/landing tasks).

There were no statistically significant differences between adductors and abductors at the moment of strength for absolute values (N). No statistically significant differences were obtained in the conventional ratio (Z = −0.456, p = 0.648) nor the functional ratio (Z = −0.335, p = 0.738) between D and ND members. There were statistically significant differences in the peak torques between the dominant and non-dominant members in the flexion function (Z = −4.198, p < 0.01) and in the extension function (Z = −4.197, p < 0.01) of the knee in concentric muscular action, and the flexion (Z = −4.198, p < 0.01) and in the extension (Z = −4.198, p < 0.01) of the knee in eccentric muscular action.
abductors (ADD:ABD) using the Wilcoxon test. non-dominant members (ND) and adductors vs. Comparisons were made between dominant members (D) vs. Body composition was measured using a bioelectrical impedance (InBody770), and the dynamometry was performed by an isokinetic dynamometer (Biodex System 3) for knee flexion and extension, and by an isometric dynamometer (Smart Groin Trainer), for hip adduction and abduction. Twenty-three male under-19 soccer players participated in this study (age: 17.7 ± 0.2 years height: 173.0 ± 1.1 cm body mass: 66.1 ± 1.3 kg). The purpose of this study was to evaluate the strength of the knee flexors and extensors and hip abductor and adductor muscles in young soccer players.
