Painful extensor carpi ulnaris tendon instability has various treatments with limited available outcome data. We treated 12 wrists of 11 patients (including eight collegiate or professional athletes) with dorsal transposition of the extensor carpi ulnaris tendon to lie over the 5th compartment, stabilized with a retinacular sling from 2010-2015. All patients had symptom resolution and returned to sport at the pre-injury level by 3 months after surgery. Mean post-surgical Patient Reported Outcomes Measurement Information System (PROMIS) upper extremity score was 56, and PROMIS pain interference score was 42...

There is no clear evidence that vitamin D effectively improves physical capacity in high-level athletes. The aim of this study was to confirm that vitamin D supplementation of soccer players during eight-week high-intensity training would have a significant effect on their aerobic capacity. The subjects were divided into two groups: the experimental one that was supplemented with vitamin D (SG, n = 20), and the placebo group (PG, n = 16), not supplemented with vitamin D. All the players were subjected to the same soccer training described as High-Intensity Interval Training (HIIT)...

Reamed intramedullary (IM) screw fixation for proximal fifth metatarsal fractures is technically challenging with potentially devastating complications if basic principles are not followed. A case of an iatrogenic fourth-degree burn after elective reamed IM screw fixation of a proximal fifth metatarsal fracture in a high-level athlete is reported. The case was complicated by postoperative osteomyelitis with third-degree soft-tissue defect. This was successfully treated with staged autologous bone graft reconstruction, tendon reconstruction, and local bi-pedicle flap coverage...

CASE: A 9-year-old boy sustained intrasubstance tears of the rotator cuff and periscapular muscles due to a fall, resulting in scapular winging and severely decreased shoulder range of motion. Treatment consisted of a modified thoracolumbosacral orthosis (TLSO) with a shoulder immobilizer attachment (to reduce the scapula to the thoracic wall and hold the arm in 10° of abduction). The brace was worn for 8 weeks. The patient recovered full, pain-free shoulder function and range of motion, and returned to high-level athletics...

The aims of this study were to evaluate movement patterns of topspin forehand, to define the main principles of performing this shot, and to determine the essential differences in individual types of topspin forehand. In total, 10 female high-level athletes participated in this study. The BTS analysis system was used with a novel model for the range-of-motion measurement. An acoustic sensor was attached to the racket for identification of a ball-racket contact. Players, performing topspin forehand, attempt to achieve maximal racket velocity based on the principles of proximal-to-distal sequences and summation of speed with a stretch-shortening character of cycle...

Transient airway narrowing can occur during or following exercise, a phenomenon called exercise-induced bronchoconstriction (EIB). The main mechanism of EIB is considered to be airway dehydration, resulting from increased ventilation during exercise. In asthma, such water loss causes an increase in airway fluid osmolarity, inducing airway smooth muscle contraction following the release of mediators from airway inflammatory cells. Asthmatics frequently experience EIB, but it may also be observed in others not reporting asthma symptoms, particularly elite endurance athletes...

BACKGROUND Acute exertional compartment syndrome (AECS) is a rare cause of leg pain often associated with a delay in diagnosis and potentially leading to irreversible muscle and nerve damage. CASE REPORT We present the case of a previously healthy, high-level athlete who presented with the acute onset of unilateral anterior leg pain and foot drop the day after a strenuous workout. He was diagnosed with compartment syndrome and rhabdomyolysis. His management included emergent fluid resuscitation, fasciotomies, debridement of necrotic muscle from his anterior compartment, and delayed primary closure...

Objectives: While the health benefits of running are legitimately advocated, participation in running can also lead to health problems. There is a high range of reported prevalence rates especially of running-related overuse injuries in high-level athletes and during competition. Little consensus exists for acute injuries and illnesses especially in recreational runners. Therefore, the aim of this study was to record the prevalence of health problems in recreational long-distance runners preparing for an event...

The purpose of this study was to identify the effects of superficial cooling on physiological responses while training in a warm, humid environment during an international judo training camp. Sixteen judokas (8 women and 8 men) participated in the experiment. Four high-level women and four men were randomly assigned to wear a cooling vest (vest group, VG) during the recovery periods within a training session (i.e. 8 bouts of 5 min fighting with 5 min rest) and up to 10 min after the session, while the remaining athletes in the control group (CG) trained without the use of any cooling aids...

Current training and monitoring methods in sprint kayaking are based on the premise that upper-body muscular strength and aerobic power are both important for performance, but limited evidence exists to support this premise in high-level athletes. Relationships between measures of strength, maximal oxygen uptake (VO2max) and 200-m race times in kayakers competing at national-to-international levels were examined. Data collected from Australian Canoeing training camps and competitions for 7 elite, 7 national and 8 club level male sprint kayakers were analyzed for relationships between maximal isoinertial strength (3-RM bench press, bench row, chin-up and deadlift), VO2max on a kayak ergometer, and 200-m race time...

PURPOSE: Asthma is frequently reported in endurance athletes. The aim of the present study was to assess the long-term airway inflammatory response to endurance exercise in high-level athletes with and without asthma. METHODS: In a cross-sectional design, 20 asthmatic athletes (10 swimmers and 10 cross-country skiers), 19 athletes without asthma (10 swimmers and 9 cross-country skiers), and 24 healthy nonathletes completed methacholine bronchial challenge, lung function tests, and sputum induction on two separate days...

Anterior cruciate ligament (ACL) reconstruction is a successful procedure with high rates of return to sport. However, some patients experience persistent instability and graft failure. These adverse events have a significant impact, especially on high-level athletes. In an effort to improve outcomes for these patients, more attention is being paid to the anatomic structures at the anterolateral aspect of the knee. The anterolateral structures of the knee have been shown to play a major role in decreasing rotatory knee instability and forces across the ACL graft following reconstruction...

The discovery of hyperferritinemia is often fortuitous, revealed in results from a laboratory screening or follow-up test. The aim of the diagnostic procedure is therefore to identify its cause and to identify or rule out hepatic iron overload, in a three-stage process. In the first step, clinical findings and several simple laboratory tests are sufficient to detect four of the most frequent causes of high ferritin concentrations: alcoholism, inflammatory syndrome, cytolysis, and metabolic syndrome. None of these causes is associated with substantial hepatic iron overload...

The official reports on doping behavior in kickboxing are alarming, but there have been no empirical studies that examined this problem directly. The aim of this study was to investigate the prevalence, gender differences and covariates of potential-doping-behavior, in kickboxing athletes. A total of 130 high-level kickboxing athletes (92 males, 21.37 ± 4.83 years of age, 8.39 ± 5.73 years of training experience; 38 women, 20.31 ± 2.94 years of age; 9.84 ± 4.74 years of training experience) completed questionnaires to study covariates and potential-doping behavior...

CONTEXT: Athletes at the highest levels appear to be most affected by sport-related injuries and suffer both physiologically and psychologically. Established models of psychological responses to injury however do not offer a comprehensive explanation based on Post-Traumatic Stress Disorder (PTSD), though some studies suggest that injuries may be interpreted as traumatic. Studies also suggest that perceived self-efficacy may be a mediator of PTSD development. OBJECTIVE: This study examines the psychological sequelae experienced by high-level athletes as a result of sport related injuries based on a PTSD-Self-Efficacy framework...
