An Exploration of the Relationship Between Disordered Eating, Exercise Dependence, and Athletic Injury
Carrie B. Scherzer, Jeremy Trenchuk, Meaghan Peters, and Robert Mazury
Injuries in sport are often unpredictable but also inevitable. Athletes can fuel and prime their bodies to be ready for competition, only to be sidelined due to injury. Others may engage in unhealthy behaviors that could predispose them to injuries, such as disordered eating; athletes have higher
The Influence of Playing Experience and Position on Injury Risk in NCAA Division I College Football Players
Robert McCunn, Hugh H.K. Fullagar, Sean Williams, Travis J. Halseth, John A. Sampson, and Andrew Murray
The potential for physical injury is an accepted risk that differs in size across all sports. The cost of sustaining an injury is multifaceted and the burden is shared among numerous parties, not least the athlete themselves. Consequences incorporate financial, 1 long-term health, 2 emotional
Importance of Various Training-Load Measures in Injury Incidence of Professional Rugby League Athletes
Heidi R. Thornton, Jace A. Delaney, Grant M. Duthie, and Ben J. Dascombe
Purpose:
To investigate the ability of various internal and external training-load (TL) monitoring measures to predict injury incidence among positional groups in professional rugby league athletes.
Methods:
TL and injury data were collected across 3 seasons (2013–2015) from 25 players competing in National Rugby League competition. Daily TL data were included in the analysis, including session rating of perceived exertion (sRPE-TL), total distance (TD), high-speed-running distance (>5 m/s), and high-metabolic-power distance (HPD; >20 W/kg). Rolling sums were calculated, nontraining days were removed, and athletes’ corresponding injury status was marked as “available” or “unavailable.” Linear (generalized estimating equations) and nonlinear (random forest; RF) statistical methods were adopted.
Results:
Injury risk factors varied according to positional group. For adjustables, the TL variables associated most highly with injury were 7-d TD and 7-d HPD, whereas for hit-up forwards they were sRPE-TL ratio and 14-d TD. For outside backs, 21- and 28-d sRPE-TL were identified, and for wide-running forwards, sRPE-TL ratio. The individual RF models showed that the importance of the TL variables in injury incidence varied between athletes.
Conclusions:
Differences in risk factors were recognized between positional groups and individual athletes, likely due to varied physiological capacities and physical demands. Furthermore, these results suggest that robust machine-learning techniques can appropriately monitor injury risk in professional team-sport athletes.
Acute:Chronic Workload Ratio: Conceptual Issues and Fundamental Pitfalls

The number of studies examining associations between training load (TL) and injury has increased exponentially in recent years. One of the most popular TL metrics in the current literature, embraced by practitioners and researchers, is the acute:chronic workload ratio (ACWR). 1 ACWR has been

The Effect of a 3-Month Prevention Program on the Jump-Landing Technique in Basketball: A Randomized Controlled Trial
Inne Aerts, Elke Cumps, Evert Verhagen, Bram Wuyts, Sam Van De Gucht, and Romain Meeusen
Context:
In jump-landing sports, the injury mechanism that most frequently results in an injury is the jump-landing movement. Influencing the movement patterns and biomechanical predisposing factors are supposed to decrease injury occurrence.
Objectives:
To evaluate the influence of a 3-mo coach-supervised jump-landing prevention program on jump-landing technique using the jump-landing scoring (JLS) system.
Design:
Randomized controlled trial.
Setting:
On-field.
Participants:
116 athletes age 15–41 y, with 63 athletes in the control group and 53 athletes in the intervention group. Intervention: The intervention program in this randomized control trial was administered at the start of the basketball season 2010–11. The jump-landing training program, supervised by the athletic trainers, was performed for a period of 3 mo.
Main Outcome Measures:
The jump-landing technique was determined by registering the jump-landing technique of all athletes with the JLS system, pre- and postintervention.
Results:
After the prevention program, the athletes of the male and female intervention groups landed with a significantly less erect position than those in the control groups (P < .05). This was presented by a significant improvement in maximal hip flexion, maximal knee flexion, hip active range of motion, and knee active range of motion. Another important finding was that postintervention, knee valgus during landing diminished significantly (P < .05) in the female intervention group compared with their control group. Furthermore, the male intervention group significantly improved (P < .05) the scores of the JLS system from pre- to postintervention.
Conclusion:
Malalignments such as valgus position and insufficient knee flexion and hip flexion, previously identified as possible risk factors for lower-extremity injuries, improved significantly after the completion of the prevention program. The JLS system can help in identifying these malalignments.
Level of Evidence:
Therapy, prevention, level 1b.
