The squat is an assessment of lower extremity alignment during movement, however there is little information regarding altered joint kinetics during poorly performed squats. The purpose of this study was to examine changes in joint kinetics and power from altered knee alignment during a squat. Thirty participants completed squats while displacing the knee medially, anteriorly, and with neutral alignment (control). Sagittal and frontal plane torques at the ankle, knee, and hip were altered in the descending and ascending phase of the squat in both the medial and anterior malaligned squat compared to the control squat...

BACKGROUND AND PURPOSE: Youth participation in basketball is on the rise, with basketball one of the top five participation sports in Australia. With increased participation there is a need for greater awareness of the importance of the pre-participation examination, including musculoskeletal screening and functional performance testing as part of a multidisciplinary approach to reducing the risk for future injuries. As majority of all basketball injuries affect the lower extremities, pre-participation musculoskeletal screening and functional performance testing should assess fundamental movement qualities throughout the kinetic chain with an emphasis on lower extremity force characteristics, specifically eccentric loading tasks...

PURPOSE: To describe how athletes with disabilities talk about their experiences of participating in competitive disability sport in South Africa. METHOD: In-depth semi-structured interviews were conducted with 20 athletes with disabilities. Data were analysed via thematic content analysis using an inductive data driven process. RESULTS: Participants described their involvement in competitive sport as a positive experience; they described it as a catalyst for the recasting of identities and reframing an understanding of physical impairment, a context for empowerment and resistance of disablist attitudes, and an arena in which a sense of inclusion and belonging is experienced...

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: Relative age effects (RAEs) typically favour older members within a cohort; however, research suggests that younger players may experience some long-term advantages, such as longer career length. The purposes of this study were to replicate previous findings on RAEs among National Hockey League (NHL) ice hockey players, National Basketball Association (NBA) basketball players and National Football League (NFL) football players and to investigate the influence of relative age on career length in all three sports...

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...

We have observed that in professional sporting organisations the staff responsible for physical preparation and medical care typically practice in relative isolation and display tension in regards their attitudes toward training load prescription (much more, and much less training respectively). Recent evidence shows that relatively high chronic training loads, when they are appropriately reached, are associated with reduced injury risk and better performance. Understanding this link between performance and training loads removes this tension, but requires a better understanding of the relationship between the acute:chronic workload ratio (ACWR), and it's association with performance and injury...

BACKGROUND: Prostate cancer is the most common non-cutaneous malignancy in men. Today most patients may expect to live years following the diagnosis and may thus experience significant morbidity due to disease progression and treatment toxicity. In order to address some of these problems exercise has been suggested and previously studies have shown improvements of disease specific quality of life and a reduction in treatment-related toxicity. Cohort studies with long term follow up have suggested that physical activity is associated with improved survival in prostate cancer patients...

Cold therapy is commonly used as a method to relieve pain and inflammation. This review focuses primarily on two methods of cold therapy that have received recent attention: whole-body cryotherapy and partial-body cryotherapy. These methods are used to induce physiological and psychological benefits in humans in the context of medicine, health and sports. The subjects experiencing cryotherapy are dressed in minimal clothing and are exposed to very cold air (at -110°C or less) for 1-4min. Despite the increasing scientific interest in these methods, there is a lack of information about the technologies used...

Sports nutrition professionals aim to influence nutrition knowledge, dietary intake and body composition to improve athletic performance. Understanding the interrelationships between these factors and how they vary across sports has the potential to facilitate better-informed and targeted sports nutrition practice. This observational study assessed body composition (DXA), dietary intake (multiple-pass 24-hour recall) and nutrition knowledge (two previously validated tools) of elite and sub-elite male players involved in two team-based sports; Australian football (AF) and soccer...
