Sport-related concussion has been shown to alter cerebral blood flow (CBF) both acutely and chronically, and may exert cumulative effects across multiple injuries. Such dysfunction may be mediated by trauma-induced deficits to CBF control mechanisms, though our understanding of these effects is limited, including dynamics of neurovascular coupling (NVC) responses (i.e. CBF responses to neurologic demand). 179 junior-level contact sport athletes completed preseason testing - 42 reported never having experienced a concussion (Hx-) while 31 had endured three or more (Hx3+)...

BACKGROUND: Clinicians typically rely on neuropsychological and balance tests to track concussion recovery. The aforementioned tests imply impairments that are based on performance, but these tests do not directly measure brain physiology throughout concussion recovery. Because of these issues, an objective biomarker that can index severity and the recovery timeline is needed. Moreover, the number of concussions occurring at a recreational level requires the biomarker to be easily administered in a cost effective manner, and the results easily interpreted...

Creatine is one of the most popular nutritional ergogenic aids for athletes. Studies have consistently shown that creatine supplementation increases intramuscular creatine concentrations which may help explain the observed improvements in high intensity exercise performance leading to greater training adaptations. In addition to athletic and exercise improvement, research has shown that creatine supplementation may enhance post-exercise recovery, injury prevention, thermoregulation, rehabilitation, and concussion and/or spinal cord neuroprotection...

INTRODUCTION: In 2014, 60 million youth ages 6-18 participated in some form of generalized athletics. 3.5 million children are injured annually participating in organized sport or recreational activities. While sound physical education can decrease the burden of youth sports injuries, the median annual physical education budget of $764 for United States elementary, middle and high schools may not allow enough flexibility to apply evidenced-based guidelines. EVIDENCE ACQUISITION: The topics were selected after a careful review of the 2016 National Strength and Conditioning Association Position Statement on Long-Term Athletic Development...

BACKGROUND: Anterior cruciate ligament (ACL) graft failure and contralateral ACL tears are more frequent in children and adolescents than adults. The reasons for higher subsequent injury rates in this population are incompletely understood. METHODS: We analyzed a continuous cohort of patients who were <18 years of age. Subjects underwent isolated, primary ACL reconstruction with autograft between 2006 and January 1, 2014, and had a minimum 2-year follow-up. Return-to-sport characteristics were described, and multivariable Cox regression modeling was used to identify predictors of a second ACL injury...

Lumbar disk herniation, degenerative disk disease, and spondylolysis are the most prevalent lumbar conditions that result in missed playing time. Lumbar disk herniation has a good prognosis. After recovery from injury, professional athletes return to play 82% of the time. Surgical management of lumbar disk herniation has been shown to be a viable option in athletes in whom nonsurgical measures have failed. Degenerative disk disease is predominately genetic but may be accelerated in athletes secondary to increased physiologic loading...

BACKGROUND: Injuries in team sports are normally characterised by the incidence, severity, and location and type of injuries sustained: these measures, however, do not provide an insight into the variable injury-burden experienced during a season. Injury burden varies according to the team's match and training loads, the rate at which injuries are sustained and the time taken for these injuries to resolve. At the present time, this time-based variation of injury burden has not been modelled...

BACKGROUND: Good outcomes have been reported after surgical treatment for acute or non-union of displaced midshaft clavicle fractures. However, the postoperative rehabilitation and timeline for a complete functional recovery are poorly documented. The purpose of the current study was to evaluate the efficacy of an immediate motion protocol following plate fixation of a midshaft clavicle fracture and to compare functional recovery between acute and nonunion cases. METHODS: Between October 2011 and July 2015, all patients above the age of 18, having either an acute or a non-unionof the midshaft clavicle fracture, were considered as potentially eligible for inclusion in this prospective case-control study...
