Purpose: Asthma is the most common chronic disease among children. Exercise-induced bronchoconstriction which is common in asthmatic patients also occurs in individuals with no prior asthma diagnosis. Despite this and the fact that soccer is a high ventilation sport, there are no validated asthma management protocols in place for soccer coaches. This study aims to address 1) soccer coaches' current knowledge on asthma, 2) whether there is a need for asthma-related training, and 3) any barriers to administration of such training...

Osteitis pubis is a common cause of chronic groin pain, especially in athletes. Although a precise etiology is not defined, it seems to be related to muscular imbalance and pelvic instability. Diagnosis is based on detailed history, clinical evaluation, and imaging, which are crucial for a correct diagnosis and proper management. Many different therapeutic approaches have been proposed for osteitis pubis; conservative treatment represents the first-line approach and provides good results in most patients, especially if based on an individualized multimodal rehabilitative management...

Background: Major League Baseball (MLB) players are throwing the ball faster and hitting harder than ever before. Although some safety measures have been implemented, by decreasing the 15 days on the disabled list (DL) to the 7 days on the DL, concussion rates remain high across positions and may impact player performance. Our hypothesis was, there would be an increase in concussion incidence following implementation of the 7 day DL, but this would not have a negative impact on player's postconcussion performance...

Lateral epicondylitis (LE) is a significant source of pain and dysfunction resulting from repetitive gripping or wrist extension, radial deviation, and/or forearm supination. Although most cases are self-limiting over several years, controversy exists regarding the best treatment strategy for chronic LE. Nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy (PT), shockwave therapy, and injections with corticosteroids or biologics are all conservative treatment options for LE. For refractory cases, surgical options include open, arthroscopic, and percutaneous techniques...

Snowboarding has seen a continuous increase in popularity, leading to an increase in the number of snowboarding injuries seen in orthopedic practice. Upper-extremity injuries are more common than lower-extremity, spine, and pelvis injuries. In this review, we focus on the most common snowboarding injuries of the extremities, spine, and pelvis and provide an overview of their respective rehabilitation and return-to-sport protocols. Despite many of the injuries seen in snowboarding also occurring in other sports, objective data about rehabilitation and return to sport are lacking for many injuries...

Introduction: Elbow ulnar collateral ligament (UCL) injuries in gymnastics have not been well documented in the literature, in comparison to UCL injuries in baseball. Few studies have examined the mechanism and nonoperative management of this injury, and no studies to date have been published on incidence of injury and return to play recommendations in gymnastics. Patient case review: A literature search was performed using PubMed to review articles from 1980 to 2016 that addressed the biomechanics of UCL injury in baseball and gymnastics, the anatomy of the elbow, injury rates, surgical vs non-surgical management, rehabilitation, and return to play recommendations for the sport of gymnastics...

The Functional Movement Screen (FMS) is a popular movement screen used by rehabilitation, as well as strength and conditioning, professionals. The FMS, like other movement screens, identifies movement dysfunction in those at risk of, but not currently experiencing, signs or symptoms of a musculoskeletal injury. Seven movement patterns comprise the FMS, which was designed to screen fundamental movement requiring a balance between stability and mobility. The 7 movement patterns are summed to a composite FMS score...

Treatment of symptomatic meniscal tears continues to evolve as we improve our understanding of the biomechanical role of the meniscus and its long-term importance to the health of the knee joint. Suture repair of meniscal tears is challenging and continues to rise as we aim to preserve meniscal tissue. Outside-in meniscal suture techniques may involve using expensive equipment that is not readily available for immediate use in most operating rooms. Aware of the different techniques available, the authors describe a fast and reproducible technique that does not require the use of specific material or equipment...

Introduction: The stability of hematological status indices is a key determinant of optimal sport performance. The capacity to monitor hematological behaviors of elite soccer players may better explain the stresses placed upon physiological systems and the potential decrements in performance and physical capacity. The primary aim of this investigation was to examine the post-seasonal hematological status of professional top-level soccer players in response to seasonal match-play and training demands, in terms of the training practices, intensity, and loadings that they experience before, during, and after each season...

The sub-2-hour marathon is a new barrier in endurance running performance, and it has been widely debated in the scientific community. In this review we present a mathematical model to estimate the possible year when a male could break through the sub-2-hour barrier, and also an estimation of when a female could break Paula Radcliffe's marathon running record. Further, we present several aspects (ie, physiology, nationality, age, biomechanics, pacing, and drafting) that are associated with marathon running performance in elite runners and, finally, the possible characteristics of the male to break the sub-2-hour barrier...

With the growing popularity of water-based sports, cases of swimming-induced pulmonary edema (SIPE) are becoming increasingly recognized. SIPE, a potentially life-threatening condition, is an acute cause of breathlessness in athletes. It has been described frequently in scuba divers, swimmers, and triathletes and is characterized by symptoms and signs of pulmonary edema following water immersion. It is important to recognize that athletes' symptoms can present with a spectrum of severity from mild breathlessness to severe dyspnea, hemoptysis, and hypoxia...
