Effects of Pitching a Simulated Game on Upper Extremity Kinematics in Youth Baseball Pitchers

Gretchen D. Oliver and Hillary A. Plummer

Article Type: Original Research Article | First Published: August 09, 2015

Overuse injuries in youth baseball players have increased exponentially with the insurgence of participation in the sport. It has been estimated that 5 million children (6-17 years) participate in organized youth baseball in the United States. Additionally, it has been documented in a survey of 476 youth pitchers (9-14 years) that roughly half reported either shoulder or elbow pain while pitching, thus leading researchers to speculate overuse inj...

Paediatric Hip Pain: A Rare Injury

Raj Subbu and Fares Haddad

Article Type: Case Report | First Published: August 07, 2015

Paediatric hip pain in young athletes can be a diagnostic challenge for clinicians. The anatomy of the paediatric pelvis and surrounding structures varies considerably to that of an adult and therefore is predisposed to different types of injuries which can lead to future deformities if not managed appropriately. Unlike adult pelvic fractures, which have set guidelines and management strategies, less research exists on these injuries in the paedi...

Effect of Hypercapnic Severity on Plasma Ammonia Accumulation and Respiratory Exchange Ratio during Incremental Exercise

Takahide Kato, Takaaki Matsumoto, Atsuko Tsukanaka, Masataka Nakano, Ryo Ito, Masato Amano, Marc Cole and Stanley M Yamashiro

Article Type: Original Investigation | First Published: July 20, 2015

Blood lactate (La) and ammonia (Am) concentrations are widely accepted markers of metabolism not only in clinical studies but also during exercise. Elevations from normal resting levels of both are observed in exercise and associated with deleterious effects such as fatigue. A decrease in blood La concentration during exercise under hypercapnic conditions was previously reported, and La threshold (LT) was unchanged by hypercapnia....

Feasibility of Focused Cardiac Ultrasound in Pre-participation Screening

Miriam L. Fishman, Jennifer Shea, Brian G. Choi and Allen J. Solomon

Article Type: Original Research | First Published: May 29, 2015

Objective: Current American Heart Association (AHA) guidelines for pre-participation athletic screening recommend a 12-point history and exam to minimize the risk of sudden cardiac death. We tested the hypothesis that focused cardiac ultrasound (FCU) performed and simultaneously interpreted by a cardiologist using a handheld ultrasound device would be a feasible addition. Methods: We performed pre-participation screening according to AHA recommen...

A New View of Responses to First-Time Barefoot Running

Michael Wilkinson, Nick Caplan, Richard Akenhead and Philip R Hayes

Article Type: Original Investigation | First Published: May 28, 2015

We examined acute alterations in gait and oxygen cost from shod to-barefoot running in habitually-shod well-trained runners with no prior experience of running barefoot. Thirteen runners completed six-minute treadmill runs shod and barefoot on separate days at a mean speed of 12.5km.h-1. Steady-state oxygen cost in the final minute was recorded. Kinematic data were captured from 30-consecutive strides. Mean differences between conditions were est...

Matthew Wellisch, Peter Hamer, Luke Hopper, Max Bulsara and James Debenham

Article Type: Original Research | First Published: May 24, 2015

Eccentric loading of the ankle plantar Flexor's (PF) has demonstrated clinical efficacy in the conservative treatment of Achilles tendinopathy, however, its mechanism of therapeutic benefit remains unclear. The purpose of this study was to examine the effects of PF eccentric loading on PF angle to peak torque (AtPT), peak torque (PT) and lower limb vertical stiffness. Thirty healthy volunteers were randomised to an eccentric (n=15) or concentric ...

Effectiveness of Bracing and Taping, and the Influence of Light Finger Touch, During Unexpected Ankle Inversion Perturbations

J. Daniel Freedman, Youngmin Jun, David A. Humphreys and James P Dickey

Article Type: Orginal Research | First Published: May 15, 2015

Ankles are the most frequent site of musculoskeletal injury and a major cause for lost time in sports. Taping and bracing are commonly used to support unstable ankle joints. The purpose of this project was to evaluate whether taping or bracing effectively reduce ankle motion, or alter the timing or amplitude of muscle activation, during unexpected perturbations. 14 male subjects stood on their right foot on an inversion motion platform and underw...

Influence of 120-Day Stimulated Microgravity with Countermeasures on Human Muscle Musculo-Tendinous Stiffness and Contractile Properties

Yuri A Koryak

Article Type: Research Article | First Published: May 15, 2015

It is well known that the unloading of the musculoskeletal system by actual or simulated microgravity causes numerous changes in the musculoskeletal system, such as muscular atrophy and decreased contraction strength, both after relatively short-term (10-17) and long-term (>5 weeks) periods of unloading. The deterioration of musculoskeletal function causes no direct health hazards and does not affect the capacity for work during short-term space ...

Article Type: Case Report | First Published: April 17, 2015

Apophyseal avulsion fractures are almost exclusive to the adolescent population. It has been commonly associated with sports injuries. In our case reports, we identify two cases of these apophyseal avulsion fractures with no history of routine physical activity. In the context of our patients, identifying causation of hip pain was essential to understanding the mechanism of any trauma resulting in fractures. The adolescents presented in this case...

Travis W. Beck

Article Type: Research Article | First Published: March 20, 2015

The purpose of this study was two-fold: (1) to compare the responses for traditional EMG amplitude measures with those from the crossspectrum approach for assessing agonist-antagonist interaction, and (2) to examine changes in the agonist-antagonist interaction for the elbow flexors and extensors with increases in movement velocity. Eighteen healthy, college-aged subjects (mean SD age = 21.8 2.7 yrs) volunteered to perform maximal, concentric...
