PURPOSE: To determine return to play (RTP) rates after biceps tenodesis (BT) in professional baseball players. METHODS: Major League Baseball has maintained a prospective database containing all major and minor league baseball players who have undergone shoulder surgery since 2010. All players who had undergone BT were included. Minimum follow-up was 24 months, and thus we included data from 2010 to 2013. Using this database we determined the incidence, demographics, prior surgery history, concomitant procedures, RTP rates, and time to RTP...

CONTEXT: Following a baseball pitching bout, changes can occur to glenohumeral range of motion that could be linked to injury. These effects are in part due to the posterior shoulder's eccentric muscle activity, which can disrupt muscle contractile elements and lead to changes in muscle cross sectional area (CSA), as measured by ultrasound. OBJECTIVE: To assess changes in muscle CSA, and range of motion immediately before and after pitching, and days 1-5 following pitching...

Abel and Kruger (2010) found that the smile intensity of professional baseball players who were active in 1952, as coded from photographs, predicted these players' longevity. In the current investigation, we sought to replicate this result and to extend the initial analyses. We analyzed (a) a sample that was almost identical to the one from Abel and Kruger's study using the same database and inclusion criteria ( N = 224), (b) a considerably larger nonoverlapping sample consisting of other players from the same cohort ( N = 527), and (c) all players in the database ( N = 13,530 valid cases)...

Qi Zhang, Sündüz Keles
Chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) has enabled discovery of genomic regions enriched with biological signals such as transcription factor binding and histone modifications. Allelic-imbalance (ALI) detection is a complementary analysis of ChIP-seq data for associating biological signals with single nucleotide polymorphisms (SNPs). It has been successfully used in elucidating functional roles of non-coding SNPs. Commonly used statistical approaches for ALI detection are often based on binomial testing and mixture models, both of which rely on strong assumptions on the distribution of the unobserved allelic probability, and have significant practical shortcomings...

Milou Tessa Brand, Rita Ferraz de Oliveira
Skilled actions are the result of a perceptual-motor system being well-calibrated to the appropriate information variables. Changes to the perceptual or motor system initiates recalibration, which is the rescaling of the perceptual-motor system to informational variables. For example, a professional baseball player may need to rescale their throws due to fatigue. The aim of this systematic review is to analyse how recalibration can and has been measured and also to evaluate the literature on recalibration. Five databases were systematically screened to identify literature that reported experiments where a disturbance was applied to the perceptual-motor system in functional perceptual-motor tasks...

Upper extremity injuries are associated with significant morbidity in throwing athletes, and prevention and diagnosis of overuse injuries in these athletes are increasingly being emphasized. Although stress fractures are common overuse injuries, stress fractures of the upper extremity are relatively rare. To our knowledge, a stress fracture of the radial shaft has not been reported in a throwing athlete. In this article, we describe the case of a Major League Baseball pitcher who presented with a stress fracture of the lateral cortex of the radius, likely caused by contractile forces of the supinator muscle, arising after his attempt to develop a new pitch...

Background: The purpose of this paper was to report normative data on regional sweat sweat-sodium concentrations of various professional male team-sport athletes, and to compare sweat-sodium concentrations among sports. Data to this effect would inform our understanding of athlete sodium requirements, thus allowing for the individualisation of sodium replacement strategies. Accordingly, data from 696 athletes (Soccer, n = 270; Rugby, n = 181; Baseball, n = 133; American Football, n = 60; Basketball, n = 52) were compiled for a retrospective analysis...

Quadriceps tendon rupture is an uncommon injury that usually occurs in middle-aged and elderly men with a history of chronic illnesses. We report the case of a 17-year-old healthy adolescent male baseball player who sustained this injury as a result of sudden deceleration in his left knee. He initially reported to the emergency department and then presented to our practice, where he was diagnosed with a quadriceps tendon tear. Preoperatively, he was unable to perform a single straight-leg raise. During surgical repair, the free edge of the quadriceps tendon was mobilized and anchored into the superior pole of the patella, followed by sutures to ensure reinforcement of the quadriceps footprint...

The present study examined the influence of attentional focus on performance during a long-distance throwing task. Twelve participants executed three maximum-effort, long-distance baseball throwing attempts in three focus conditions: internal focus on wrist flexion (wrist internal focus), internal focus on the separation between pelvis and upper torso orientations (torso internal focus), and external focus on the ball path (external focus). Compared with the external focus and torso internal focus conditions, performance was poorer in the wrist internal focus condition...

Nicholas G Mohtadi, Denise S Chan
BACKGROUND: Physicians counseling athletes on the prognosis of sport-specific performance outcomes after anterior cruciate ligament reconstruction (ACLR) depend on the published literature. However, critical appraisal of the validity and biases in these studies is required to understand how ACLR affects an athlete's ability to return to sport, the athlete's sport-specific performance, and his or her ability to achieve preinjury levels of performance. PURPOSE: This review identifies the published prognostic studies evaluating sport-specific performance outcomes after ACLR...
