BACKGROUND: Athletes experience various situations and conditions that can interfere with their sleep, which is crucial for optimal psychological and physiological recovery as well as subsequent performance. Conventional sleep screening and intervention approaches may not be efficacious for athletes given their lifestyle, the demands of training and travel associated with interstate/international competition. OBJECTIVES: The present systematic review aimed to summarize and evaluate sleep intervention studies targeting subsequent performance and recovery in competitive athletes...

The relationship between recovery and fatigue and its impact on performance has attracted the interest of sports science for many years. An adequate balance between stress (training and competition load, other life demands) and recovery is essential for athletes to achieve continuous high-level performance. Research has focused on the examination of physiological and psychological recovery strategies to compensate external and internal training and competition loads. A systematic monitoring of recovery and the subsequent implementation of recovery routines aims at maximizing performance and preventing negative developments such as underrecovery, non-functional overreaching, the overtraining syndrome, injuries, or illnesses...

BACKGROUND: Physical activity and regular participation in recreational sports gain importance in patients' lifestyle after knee arthroplasty. Cementless unicompartimental Knee replacement with the Oxford System has been introduced into clinical routine. Currently there is no data reporting on the physical activity, return to sports rate and quality of live after medial cementless Oxford Unicompartimental Knee Replacement (OUKR). METHODS: This retrospective cohort study reports on the functional outcome of the first 27 consecutive patients (30 knees) that were consecutively treated with a cementless medial OUKR between 2007 and 2009 in our hospital...

OBJECTIVE: To determine whether continuing to play after a concussion is associated with higher symptom burden or prolonged symptom duration. DESIGN: Patients who presented for care at a sport concussion clinic within the first 3 weeks of injury were asked whether they continued to play immediately after their injury. SETTING: Sport concussion clinic within a regional tertiary care hospital. MAIN OUTCOME MEASURES: Clinical outcomes including symptom severity, symptom duration, age, time from injury-clinical presentation, sex, sport type, previous concussion history, and whether or not they experienced loss of consciousness or amnesia at the time of injury were recorded...

There is conflicting evidence regarding whether females are more adversely affected following concussion relative to males. Further, recent research suggests hormonal contraceptive (HC) use may affect symptom severity and duration post-concussion. The objective of this study was to examine the effects of sex and HC use on outcomes following concussion among collegiate varsity athletes. We hypothesized females would have longer length of recovery (LOR) and peak symptom severity would be associated with longer length of recovery in both males and females...

The present study investigates the applicability of the chemical analysis of wastewater to assess the use of doping substances by the general population and amateur athletes. To this end, an analytical methodology that can identify and quantify a list of 15 substances from the groups of anabolic steroids, weight loss products, and masking agents in wastewater has been developed. The method uses solid phase extraction to increase the detection sensitivity of the target analytes, expected to be present at very low concentrations (ng L-1 range), and decrease possible matrix interferences...

Muscle injury occurs due to trauma, strenuous exercise or sports activities; most people affected are athletes. Ineffectively treated muscle injury can negatively affect sports careers and quality of life after retirement from sports. Reports have indicated that the current therapeutic management of muscle injury, particularly anti-inflammatory drugs, are not necessarily effective. Therefore, better therapies are required. Accumulating evidence has demonstrated melatonin's potent antioxidant and anti-inflammatory actions against muscle pathology in sarcopenia or atrophy in systemic disease...

Achilles tendinopathy is a common cause of disability. Despite the economic and social relevance of the problem, the causes and mechanisms of Achilles tendinopathy remain unclear. Tendon vascularity, gastrocnemius-soleus dysfunction, age, sex, body weight and height, pes cavus, and lateral ankle instability are considered common intrinsic factors. The essence of Achilles tendinopathy is a failed healing response, with haphazard proliferation of tenocytes, some evidence of degeneration in tendon cells and disruption of collagen fibers, and subsequent increase in noncollagenous matrix...

Background: Previous studies have identified the effect of sport-related concussion on health-related quality of life through the use of patient-reported outcome measures. However, there has been little research exploring the underlying mechanisms that influence these perceptions of health-related quality of life among adolescent athletes who have sustained a sport-related concussion. Purpose: To explore the psychosocial aspects of concussion among adolescent athletes...

Lumbar spondylolysis usually occurs as a stress fracture in the pars interarticularis of the vertebra. It is a prevalent sports-related disorder and a common cause of low back pain. We encountered five athletes (4 males, 1 female) with severe low back pain. Mean age was 14.5 years. All five patients were found to have bilateral pars fracture. In all cases, staging based on the findings from computed tomography scan of the right and left pars fracture was different. On short tau inversion recovery magnetic resonance imaging (STIR-MRI) of the comparatively newer more recently injured side, high signal intensity changes were obvious and dominant at the intra- and extraosseous area, which would indicate tissue edema and/or bleeding...

OBJECTIVES: To investigate how women with bulimia nervosa (BN) and binge eating disorder (BED) experience participating in a new treatment programme for eating disorders, based on guided physical exercise and dietary therapy. DESIGN AND PARTICIPANTS: Six women with BN and four with BED were semistructurally interviewed. Transcribed interviews were analysed using a text-condensing analytic approach. RESULTS: The analysis resulted in four main categories: (1) 'a renewed attitude towards physical activity', (2) 'a new perception of food', (3) 'mixed feelings of being in a heterogeneous treatment group' and (4) 'insight in one's own recovery process', each with 2-4 subcategories to express nuances...

The psychological response to musculoskeletal injuries has been well documented, however, research on the psychological response to concussion is limited. The Profile of Mood States (POMS) and the State-Trait Anxiety Inventory (STAI) have recently been used to assess the psychological recovery of concussions. Although some studies indicate that psychological response is different for musculoskeletal injuries and concussion, there is currently not enough information to indicate this difference occurs at specific clinical milestones...

REVIEW
Bas Habets, Anke G van den Broek, Bionka M A Huisstede, Frank J G Backx, Robert E H van Cingel
BACKGROUND: Midportion Achilles tendinopathy (AT) can cause long-term absence from sports participation, and shows high recurrence rates. It is important that the decision to return to sport (RTS) is made carefully, based on sharply delimited criteria. Lack of a well-defined definition and criteria hampers the decision to RTS among athletes with AT, and impedes comparison of RTS rates between different studies. OBJECTIVE: The aim of this study was to systematically review the literature for definitions of, and criteria for, RTS in AT research...

CASE: A 38-year-old woman who had returned to sports activity (running) after having clinically recovered from anorexia nervosa presented with a bilateral femoral neck stress fracture that was treated with bilateral hip osteosynthesis. CONCLUSION: Although exercise is usually considered to be beneficial for health, heavy exercise (such as running) after recovery from anorexia nervosa may be associated with an increased risk of fracture.

CASE: A 26-year-old amateur baseball player without prodromal arm pain sustained a thrower's fracture of the humerus on a warm-up throw performed with submaximal effort. The fracture occurred during the first throwing session following a 6-week layoff. The patient was treated nonoperatively and made a full recovery, but he elected to not return to throwing sports. CONCLUSION: Because of the lack of risk factors in this case, we suggest that time off or irregularity in throwing may play a greater role in a thrower's fracture than previously established...
