National Athletic Trainers' Association Position Statement: Fluid Replacement for the Physically Active

National Athletic Trainers' Association Position Statement: Fluid Replacement for the Physically Active

McDermott BP, Anderson SA, Armstrong LE, Casa DJ, Cheuvront SN, Cooper L, Kenney WL, O'Connor FG, Roberts WO. J Athl Train. 2017 Sep;52(9):877-895. doi: 10.4085/1062-6050-52.9.02.

The National Athletic Trainers’ Association has released a new position statement to provide “evidence-based recommendations that promote optimized fluid-maintenance practices for physically active individuals”. The authors offer 31 recommendations and a comprehensive literature review. The recommendations cover the importance of maintaining fluid balance and regulation; importance of maintaining euhydration; fluid replacement; beverage additives; hydration assessment, and unique situations.

Young and Active = Lean Towards Autograft

Change in Anterior Cruciate Ligament Graft Choice and Outcomes Over Time

Kaeding CC, Pedrosa AD, Reinke EK, Huston LJ, Hewett TE, Flanigan DC, MOON Knee Group, & Spinder KP. Arthroscopy. 2017; Online Ahead of Print July 24, 2017.  

Take Home Message: Younger and highly active participants may be more appropriately advised to have an autograft for anterior cruciate reconstruction over an allograft. 

Graft choice for an anterior cruciate ligament (ACL) reconstruction remains debatable for short- and long-term health after an ACL injury.  Generally speaking, risk of reinjury is high after ACL reconstruction, but it remains unclear as to what role graft choice plays in this risk and how graft choices and retear rates have changed over time at 7 clinical sites (across 17 surgeons).

Keep Playing and Adapting

A longitudinal exploration of pain tolerance and participation in contact sports.

Thornton C, Sheffield D, and Baird A. Scand J Pain. 2017. [Epub Ahead of Print].

Take Home Message: Athletes who start participating in contact sports are more pain tolerant and become less catastrophizing than new athletes who stop participating.

A patient with greater pain tolerance is more likely to adhere to a rehabilitation program after injury. Understanding how different factors affect an athlete’s pain tolerance can help clinicians anticipate who may have lower tolerance and then tailor a rehabilitation program to optimize adherence. One key factor may be participation in contact sports; but, it remains unclear if athletes in contact sports start with a higher pain tolerance or acquire a higher pain tolerance while participating in the sport. Therefore, Thornton and colleagues completed a study to compare changes in pain tolerances over a season among athletes who started to participate in contact sports and those who started but then stopped participating (disengage).

Nurses’ Views on Interprofessional Concussion Management Teams

School nurses’ perceptions and experiences with an interprofessional concussion management team in the secondary school setting

Welch Bacon CE, Erickson CD, Kay MC, Weber ML, Valovic McLeod TC. Journal of Interprofessional Care. 2017; ahead of print.

Take Home Message: Nurses understand that they play a key role in the interprofessional concussion management team for secondary school students; however, the lack of agreement on the roles of team members suggest that protocols may be needed to foster role delineation and communication.

Students commonly need academic accommodations following a concussion to ease back into full cognitive load in a classroom. These accommodations would be best implemented by an interprofessional concussion management team that uses a collaborative, multifaceted approach to permit the safe return to activity and classroom. However, there is little research to address who should be involved and how academic accommodations would be effectively carried out. The school nurse may offer insight on the best approach to facilitate a team approach to academic accommodations. Therefore, the authors explored the school nurses’ perceptions and experiences of an interprofessional concussion management team for adolescents following a concussion in the secondary school setting.

Kerksick CM, Arent S, Schoenfeld BJ, Stout JR, Campbell B, Wilborn CD, Taylor L, Kalman D, Smith-Ryan AE, Kreider RB, Willoughby D, Arciero PJ, VanDusseldorp TA, Ormsbee MJ, Wildman R, Greenwood M, Ziegenfuss TN, Aragon AA, Antonio J. J Int Soc Sports Nutr. 2017 Aug 29;14:33. doi: 10.1186/s12970-017-0189-4.

The International Society for Sports Nutrition has released a position statement to offer an objective summary of the timing of macronutrients for healthy, exercising adults and especially highly trained individuals on exercise performance and body composition. The abstract offers 12 key points. The document ends with 14 practical applications.

Is Scapular Dyskinesis A Risk Factor or An Early Warning for Shoulder Injury?

Scapular Dyskinesis increases the risk of future shoulder pain by 43% in asymptomatic athletes: a systematic review and meta-analysis

Hickey D, Solvig V, Cavalheri V, Harrold M, Mckenna L . Br J Sport Med. 2017; ahead of print.

Take Home Message: Athletes with scapular dyskinesis have a 43% greater risk of developing shoulder pain compared with athletes without scapular dyskinesis.

One potential risk for shoulder pain is scapular dyskinesis, (altered position and/or motion of the scapula). Scapula dyskinesis is thought to place abnormal forces and disrupt the overall function of the glenohumeral joint, thereby increasing the risk of shoulder pain and impairments. Interesting scapular dyskinesis is often observed in both symptomatic and asymptomatic athletes. Therefore, it remains unclear whether the presence of scapular dyskinesis increases the risk of developing shoulder pain in asymptomatic athletes. To help investigate this question the authors conducted a systematic review to identify whether the presence of scapular dyskinesis in asymptomatic athletes increase the risk of developing future shoulder pain.

Psychological Outcomes After a False Positive ECG

Psychological Impact of Electrocardiogram Screening in National Collegiate Athletic Association Athletes

Asif IM, Annett S, Ewing JA, Abdelfattah R, Sutphin B, Conely K, Rothmier J, Harmon KG, & Drezner JA. Br J Sport Med. 2017; Online Ahead of Print July 24, 2017.  DOI: 10.11336/bjsports-2017-097909

Take Home Message: Athletes who had false positive ECG results had similar anxiety than those who tested normally.  However, they were more concerned about sport disqualification, but felt that more athletes should be screened and felt safer participating.

Electrocardiograms (ECG) can find heart arrhythmias, which may make an athlete susceptible to sudden cardiac death – the leading cause of death among athletes.  However, current recommendations do not support mandatory screening with ECG for all athletes because a thorough medical history should help identify those at risk and the possible negative outcomes of ECG screening; such as, more false positives resulting in athletic disqualification, financial burdens, and emotional distress.  These authors studied the psychological outcomes associated with false-positive ECG screening among collegiate athletes.
