OBJECT: Total disc replacement (TDR) is typically indicated in young patients with a cervical soft disc herniation. To date, there are few data on the activity level of patients after cervical TDR; in particular, from young patients who are expected to have a high activity level with frequent exercising. The expectation is that returning to active sports after cervical TDR is not restricted. METHODS: Fifty patients were treated with a monosegmental cervical TDR at our department between May 2006 and March 2012...

BACKGROUND: Growth hormone (GH) has many direct and indirect actions and roles including substrate regulation and priming of some cells of the immune system, and the expected aspects of growth and repair. Different concentrations in human body fluids reflect the exercise-induced growth hormone response (EIGR) after exercise. In populations such as elite athletes, the invasive nature of venous sampling is poorly accepted. Thus, this study examines possible viable alternatives such as urine and saliva samples and the GH concentration...

BACKGROUND: Dizziness is often reported after a sports-related concussion. Forces experienced at the time of the concussion can cause an injury to multiple anatomical areas, including the central nervous system, the vestibular system, and the cervical spine, each of which is sufficient to cause dizziness. Medical professionals routinely use the subjective history to develop hypotheses about what may be causing a patient's dizziness. No previous studies have attempted to differentiate the source of the dizziness through precise patient descriptors or the triggers of dizziness...

BACKGROUND: Connecticut (CT) passed its original sport-related concussion (SRC) law (PA 10-62) in 2010. The law requires that a health-care professional evaluate high school athletes with concussion symptoms. The purpose of this study was to evaluate two level 1 Trauma Center Emergency Department (ED) records for SRC before and after the Connecticut Public Act (CT PA) 10-62 to determine if the law had an effect on the presentation to the ED of SRCs. METHODS: A retrospective analysis of two level 1 Trauma Center Emergency Departments database was performed...

To maintain the principle of sporting fairness and to protect the health of athletes, it is essential that age limits for youth sporting competitions are complied with. Forensic scientists have developed validated procedures for age estimation in living individuals. Methods have also been published for age estimation in competitive sports. These methods make use of the ossification stage of an epiphyseal plate to draw conclusions about an athlete's age. This article presents published work on the use of magnetic resonance imaging for age estimation in competitive sports...

Speed is a crucial element an athlete must possess to be successful. In soccer, the ability to accelerate faster than your opponent can result in being first to reach a ball on a breakaway or stopping a counter attack. A unique way to train explosive movements is to evoke postactivation potentiation (PAP) in the working muscles. Traditionally, an overload stimulus with a long rest period is used, but a model utilizing an overspeed stimulus with shorter rest periods is less understood. Therefore, the purpose of this study was to determine the acute effects of varied rest intervals following assisted sprinting on bodyweight sprint time...

Hypertension continues to be the most common cardiovascular disorder in the USA and worldwide. While generally considered a disorder of aging individuals, hypertension is more prevalent in athletes and the active population than is generally appreciated. The timely detection, diagnosis, and appropriate treatment of hypertension in athletes must focus on both adequately managing the disorder and ensuring safe participation in sport while not compromising exercise capacity. This publication focuses on appropriately diagnosing hypertension, treating hypertension in the athletic population, and suggesting follow-up and participation guidelines for athletes...
