Noncontact anterior cruciate ligament injuries: risk factors and prevention strategies.
Early data on existing neuromuscular training programs suggest that enhancing body control may decrease ACL injuries in women and further investigation is needed prior to instituting prevention programs related to the other risk factors.
The sensorimotor system, part I: the physiologic basis of functional joint stability.
The nomenclature and physiologic mechanisms responsible for functional joint stability are defined and recognition and understanding the complexities involved will facilitate the continued development and institution of management strategies based on scientific rationales.

Golf instructors can consider increasing ball velocity by maximizing separation between the upper torso and pelvis at the top of and initiation of the downswing, ultimately contributing to greater ball velocity.
The Sensorimotor System, Part II: The Role of Proprioception in Motor Control and Functional Joint Stability.
Although controversy remains over the precise contributions of specific mechanoreceptors, proprioception as a whole is an essential component to controlling activation of the dynamic restraints and motor control.

Findings could indicate that a tightening of the posterior elements of the shoulder (capsule, rotator cuff) may contribute to impingement and suggest that management should include stretching to restore flexibility to the posterior shoulder.
Understanding and Preventing Noncontact Anterior Cruciate Ligament Injuries
A group of physicians, physical therapists, athletic trainers, biomechanists, epidemiologists, and other scientists interested in this area of research met to review current knowledge on risk factors associated with noncontact anterior cruciate ligament injuries.
AN EIGHT‐WEEK GOLF‐SPECIFIC EXERCISE PROGRAM IMPROVES PHYSICAL CHARACTERISTICS, SWING MECHANICS, AND GOLF PERFORMANCE IN RECREATIONAL GOLFERS

The results indicate that a golf-specific exercise program improves strength, flexibility, and balance in golfers, which result in increased upper-torso axial rotational velocity, which results in increased club head velocity, ball velocity, and driving distance.
The relationship between biomechanical variables and driving performance during the golf swing
Swing kinematic and ground reaction force data from 308 golfers were analysed to identify the variables important to driving ball velocity and these results may serve as both skill and strength training guidelines for golfers.
Knee Joint Laxity and Neuromuscular Characteristics of Male and Female Soccer and Basketball Players
Women inherently possess significantly greater knee joint laxity values, demonstrate a significantly longer time to detect the knee joint motion moving into extension, possess significantly superior single-legged balance ability, and produce significantly greater electromyographic peak amplitude and area of the lateral hamstring muscle subsequent to landing a jump.

Kinematic, vertical ground reaction forces, and strength variables in healthy collegiate female basketball, volleyball, and soccer players compared with matched male subjects were evaluated and females had significantly less knee flexion and lower leg internal rotation maximum angular displacement and significantly less peak torque to body mass than males.
