demonstrated a greater reduction in injury risk compared with interventions not including feedback. 17 Compliance with intervention programs is an important factor in the overall success of reducing ACL injury risk using feedback. 18 Compliance to these programs may be poor if the athletes and coaches are

, injury risk was shown to increase by 70% in the subsequent week when total weekly training load increased by 4 hours. 11 A strong significant association ( r  = .82) between training load and injury incidence observed in professional rugby league over 4 years 9 is consistent with elite-level Australian

beneficial than specializing in one sport, as specialization increased injury risk. One father stated, “Unfortunately [specialization] is the trend…[and] probably leads to injuries because you have so much overuse of the same muscles and the same kind of activity.” Another mother likened early specialization

A squash player’s ability to perform high-intensity variable movements is a key determinant of success at the elite level ( Wilkinson et al., 2012 ). The body composition of a squash player may affect performance as carrying excessive body fat may increase injury risk and impair agility and speed

In addition to the ankle, knee, and hip kinematics, the landing strategy and distal foot kinematics may be important factors in determining injury risk associated with transition step negotiation. Foot strike patterns or step landing strategies have

The high rate of ACL injury has led to the need for large-scale injury risk screening to aid in prevention. Cost and time alternatives to three-dimensional assessments of knee injury risk factors are necessary for largescale, clinical use. The purpose of this study was to determine the expert versus novice interrater reliability and test-retest reliability of the frontal plane projection angle (FPPA) during the single-leg squat (SLS) test. Excellent interrater reliability was demonstrated for session 1 and session 2. Excellent intrarater (i.e., test-retest) reliability was demonstrated for both the novice and expert. The minimal training requirements and excellent reliability of the FPPA during the SLS test make it a key screening tool for large-scale assessment of injury risk.
