Let’s Hop To It: ACL Patients Not as Good

A Critical Analysis of Limb Symmetry Indices of Hop Tests in Athletes After Anterior Cruciate Ligament Reconstruction: A Case Control Study

Take Home Message: Athletes after an anterior cruciate ligament (ACL) reconstruction perform poorly bilaterally in hop testing when compared with healthy matched controls. 

We have recently had a few posts on Sports Med Res investigating return to play testing after anterior cruciate ligament (ACL) reconstructive surgery (see below).  Oftentimes, the surgical side is compared to the nonsurgical side in regard to strength, function, and range of motion.  Many clinicians are increasingly using a series of single-limb hop tests as functional assessments. However, the contralateral limb may be an inappropriate comparison if it is also weak or functioning at suboptimal levels.  The authors of this case-control study compared both limbs of athletes with a previous history of an isolated ACL reconstruction to control athletes on hop test performance.

Should Athletic Trainers Add Anxiety Surveys to Preseason Baseline Testing?

Preseason Anxiety and Depressive Symptoms and Prospective Injury Risk in Collegiate Athletes

Li H, Moreland JJ, Peek-Asa C, Yang J. Am J Sports Med. 2017; ahead of print.

Take Home Message: An athlete with anxiety symptoms during preseason was more likely to get injured during a season than an athlete without symptoms.

National College Health Assessment surveys demonstrated that more than 1 in 3 NCAA student athletes reported anxiety or depressive symptoms. These symptoms can become elevated by the challenges these student-athletes face (academic demands, relationships, being away from home). Athletes with anxiety or depression symptoms may be at a higher risk of injury due to decreased concentration and/or reduced apprehension to problematic situations; however, this has not been verified in a large cohort of different sports and both sexes. Therefore, the authors followed 958 NCAA Division I athletes to determine the influence of anxiety and depressive symptoms, experienced during preseason, on risk of injury from 2 Universities during the 2007 to 2011 seasons.

Another Feather in the Cap of the FIFA 11+ Injury Prevention Program

Efficacy of the FIFA 11+ Injury Prevention Program in the Collegiate Male Soccer Player.

Silvers-Granelli H, Mandelbaum B, Adeniji O, Insler S, Bizzini M, Pohlig R, Junge A, and Snyder-Mackler L. Am J Sports Med. 2017. [Epub Ahead of Print].

Take Home Message: Implementing the FIFA 11+ injury prevention program decreases the risk of injury among collegiate male soccer players.

Soccer is an increasingly popular contact sport, which has seen participation at all levels increase. With this increase in participation comes an increased need to identify and optimize pre-activity injury prevention programs. Therefore, Silvers-Granelli and colleagues completed a cluster randomized control trial to compare the FIFA11+ injury prevention program with a control group among collegiate men’s soccer athletes.

Monitoring Athlete Training Loads: Consensus Statement

Monitoring Athlete Training Loads: Consensus Statement

Bourdon PC, Cardinale M, Murray A, Gastin P, Kellmann M, Varley MC, Gabbett TJ, Coutts AJ, Burgess DJ, Gregson W, Cable NT. Int J Sports Physiol Perform. 2017 Apr;12(Suppl 2):S2161-S2170. doi: 10.1123/IJSPP.2017-0208.

A new consensus statement from a 2016 conference entitled “Monitoring Athlete Training Loads – The Hows and the Whys” has been released to summarize the key findings and recommendations from the conference. The document is intended for coaches, sport-science and -medicine staff, and other professionals who are interested in monitoring athlete training loads. The major sections of the statement include defining training load, how is training load measured, why is athlete-load monitoring important, what are the challenges to load monitoring, and what is the future of athlete-load monitoring.

“The 2017 Concussion in Sport Group (CISG) consensus statement is designed to build on the principles outlined in the previous statements and to develop further conceptual understanding of sport-related concussion (SRC) using an expert consensus-based approach. This document is developed for physicians and healthcare providers who are involved in athlete care, whether at a recreational, elite or professional level.” The document is a very valuable resource for clinicians.

A summary of the methods is available for review.
An article on the Sport Concussion Assessment Tool 5th Edition is available.
An article on the Child Sport Concussion Assessment Tool 5th Edition is also available.
An article on the Concussion Recognition Tool 5th Edition is also available.

The authors add that “Readers are encouraged to copy and freely distribute this Berlin Consensus Statement on Concussion in Sport, the Concussion Recognition Tool version 5 (CRT5) [link to tool], the Sports Concussion Assessment Tool version 5 (SCAT5) [link to tool] and/or the Child SCAT5 [link to tool].”

Eating Disorders Persist Over Entire Season

Eating Disorders and Weight Control Behaviors Change Over a Collegiate Sport Season

Thompson A, Petrie T, & Anderson C. J Sci Med Sport. 2017; Published online ahead of print http://dx.doi.org/10.1016/j.jsams.2017.03.005 http://www.sciencedirect.com/science/article/pii/S1440244017303341              

Take Home Message: Female athletes with an eating disorder will most likely continue to have the eating disorder throughout their competitive season.

Athletes, especially females in aesthetic sports, are susceptible to an array of eating disorders.  Researchers have assessed the frequency of eating disorders in sports; however, there is limited research that have followed athletes over time to study changes in eating disorder behaviors. Therefore, these authors investigated eating disorder behaviors in collegiate female gymnasts and swimmers over the course of the course of a 5 month competitive season.

Athletic Trainers in High Schools Could Help to Bridge the Gap in Racial Disparities in Adolescent Athlete Health Care

Racial Disparities in Concussion Knowledge and Symptom Recognition in American Adolescent Athletes

Wallace J., Covassin T., Moran R. J Racial Ethn Health Disparities. 2017; ahead of print

Take Home Message: White athletes had more concussion knowledge compared to African Americans; however, African Americans that had access to an athletic trainer had greater knowledge of concussion sign and symptoms than those without an athletic trainer.

Concussion education is necessary to ensure athletes recognize the 22+ concussion signs and symptoms and the consequences of a second impact while symptomatic. In schools with no access to athletic trainers this education may be difficult to deliver or reinforce. Moreover, many youth American football participants are African American children who are more likely to have worse outcomes following a concussion, which may be a result of the absence to quality concussion education, care, and follow up that an athletic trainer provides. Unfortunately, there is a lack of research investigating the racial disparities that may exist. Therefore, the authors of this survey study aimed to identify if concussion knowledge differences exist between communities that service underserved, African-American athletes compared to white athletes, and to explore dissimilarities in concussion education knowledge between African American athletes with and without access to an athlete trainer.
