Objective: The utility of structured exercise for rehabilitation purposes early in the postacute phase (ie, beyond the initial 24-48 hours of advised rest) following sport-related concussion (SRC) remains largely unexplored. This study examined the feasibility of implementing a standardised aerobic exercise (AE) intervention in the postacute stage of SRC recovery in a sample of adolescent students with SRC compared with usual care. Methods: Symptomatic adolescents with SRC were randomised to one of two groups: Aerobic Exercise (n=8) or Usual Care (n=7)...

Objectives: In youth sports, musculoskeletal pain is often studied from the standpoint of sports injuries, but little is known about pain conditions in which athletes still participate. The aim was to study the frequency of pain and associations with maturity offset, health status and sports performance in 14-year-old sport school students. Methods: Cross-sectional design. One hundred and seventy-eight students (108 boys and 70 girls) completed anthropometric measures for maturity offset (height, weight and sitting height), questionnaires (pain mannequin and EQ-5D for health status) and sports performance tests (sprint, agility, counter-movement jump and grip strength)...

Introduction: It is assumed that a running-related (overuse) injury occurs when a specific structure of the human body is exposed to a load that exceeds that structures' load capacity. Therefore, monitoring training load is an important key to understanding the development of a running-related injury. Additionally, other distribution, magnitude and capacity-related factors should be considered when aiming to understand the causal chain of injury development. This paper presents a study protocol for a prospective cohort study that aims to add comprehensive information on the aetiology of running-related injuries and present a new approach for investigating changes in training load with regard to running-related injuries...

Aim: To record overuse injuries among male junior handball players throughout a handball season. Design: Prospective cohort study. Methods: Ten Norwegian junior male handball teams (145 players aged 16-18 years) were followed for one 10-month season. All players were sent the Oslo Sports Trauma Research Center Overuse Injury Questionaire every second week to record overuse injuries located in the shoulder, elbow, lower back and knee. The relative burden of overuse injuries was calculated in each anatomical area represented, defined as the proportion of the total cumulative severity score...

Objectives: For several decades, autologous blood doping (ABD) in sports has been a major problem, and even today there is still no reliable method for satisfactorily detecting ABD. For this kind of doping, stored individual erythrocytes are used to increase stamina and endurance caused by a higher erythrocyte level in the athlete's body. Since there is growing evidence that these cells are enriched with microRNAs (miRNAs), this study has been carried out to discover and validate all miRNAs occurring in fresh blood as well as in stored blood...

Purpose: Sprint interval training (SIT) provides a strong stimulus for improving cardiovascular fitness, which is among the key markers for premature mortality. Recent literature demonstrated that SIT protocols with as few as two stacked 20 s Wingate Anaerobic Test (WAnT) cycle sprints provide sufficient training stimulus for a robust increase in maximal aerobic power. However, this effect is lost when only one bout is performed. This suggests training adaptation is still dependent on the volume of SIT...

Background: There is limited literature that examines risk factors for injury and mild traumatic brain injury (mTBI) in mixed martial arts (MMA). An examination of previously unstudied bout and athlete characteristics that may pose health risks while partaking in this sport is warranted. Hypothesis/purpose: To determine the incidence of injury and concussion, along with the identification of risk factors that contribute to injury and mTBI in amateur and professional MMA bouts in Calgary, Alberta...

Aim: To objectively evaluate the effect of Holmich protocol-based exercise therapy on long-standing adductor-related groin pain (LSAGP). Methods: We reproduced the Holmich protocol of exercise therapy and objectively evaluated its effect on 17 male athletes (mean age, 25.07±4.96 years) suffering from LSAGP, of whom 14 participants completed the 10 weeks treatment period. The study was designed as a single-blinded, before-and-after clinical trial. Main outcome measures included pain, functional ability, hip range of motion (ROM), hip abductor and adductor muscle strength, and successful return to sports activity...

Background: The rate of depression among collegiate athletes ranges from 16% to 23%, with particularly high findings of prevalence in track and field athletes (34%). Collegiate athletes have also been found to underuse mental health resources. Given this high prevalence of depression and demonstrated reluctance to seek help, it is important to explore the awareness and understanding of depression among the individuals who work most closely with this population. Objective: To assess coaches' knowledge and awareness of depression among their athletes and describe their level of interest in receiving continuing education...

Background/aims: The contribution of inflammation to tendinopathy has been debated in the scientific literature. Several factors may contribute to this lack of clarity, including inconsistent definitions of inflammation. We hypothesised that the adoption and/or rejection of a causal link between inflammation and tendinopathy varied as a function of the 'inflammatory component' (eg, immune cell and molecular mediators included in published reviews). Methods: Twenty data items were collected from each review to determine conclusions about the role of inflammation in tendinopathy, specific definitions of the 'inflammatory component,' quality of the review and other potential correlates...

Aim: The amount of injuries, illnesses and mental health problems was calculated among circus arts students, using a method designed to capture more than just time-loss and/or medical injuries. Furthermore, injury incidence rate, injury incidence proportions, anatomical injury location and severity of injuries were assessed. Methods: A total of 44 first-year, second-year and third-year circus arts students were prospectively followed during one academic year. Every month, all students were asked to complete questionnaires by using the online Performing Artist and Athlete Health Monitor, which includes the Oslo Sports Trauma Research Centre Questionnaire on Health Problems...

Background: Participation in sports as a child improves physical and psychological health. Schools need to promote sport while protecting against injury. It is not clear whether increasing evidence on injury prevention generated from professional sport is influencing school sports practices. This study reviewed policies promoting sport safety in schools to determine whether exposure to injury risk is recognised and whether evidence based prevention and management are included. Methods: A search strategy to identify policies for children aged 4-18 years was applied to electronic databases and grey literature sources...

Background: We are developing since 2010 with Thales and the Fédération Française de Rugby (FFR) M-Rex, a new kind of rugby scrum simulator. The study questioned whether it could improve safety and protect players from injury by using it as a tool for training/coaching the packs. Aim: To explore the anticipatory postural adjustments (APAs) during the engagement of the ruck, because these predictive neck and back muscles contractions protect the spinal cord at the time of impacts, which is crucial to prevent injuries...
