AIM: The main energy delivery system of 800 meters run is the glycolytic system. Running the 800 meters causes significant changes in our body, yet our understanding of how these changes occur is limited. METHODS: We used an NMR-based metabolomics analysis to evaluate the metabolite profile changes in 19 young male athletes' urine samples after 800-meter runs and provide an overall picture of its impact. Various multivariate data analysis methods, including principal component analysis (PCA), partial least squares-discrimination analysis (PLS-DA), and orthogonal projection of latent-structure-discrimination analysis (OPLS-DA) were applied to analyze the NMR data and thus identify possible correlations between the metabolite profile changes and the alterations in biological pathways...

BACKGROUND: Fungal keratitis is difficult to treat that can result in corneal blindness requiring penetrating keratoplasty and in fungal endothalmitis. We report a case of fungal keratitis and onychomycosis simultaneously infected by Trichophyton. CASE PRESENTATION: A 77-year old male presented with ocular pain, conjunctival injection, and severe loss of vision in his left eye. His best corrected visual acuity was hand movements in the left eye, and slit-lamp examination showed a corneal ulcer with feathery margin and hypopyon...

Label-free-based detection is pivotal for real-time monitoring of biomolecular interactions and to eliminate the need for labeling with tags that can occupy important binding sites of biomolecules. One simplest form of label-free-based detection is ultraviolet-visible-near-infrared (UV-vis-NIR) spectroscopy, which measure changes in reflectivity as a means to monitor immobilization and interaction of biomolecules with their corresponding partners. In biosensor development, the platform used for the biomolecular interaction should be suitable for different molecular recognition elements...

The main aim of this study was to determine the accuracy of the ultra-wideband (UWB)-based positioning system Ubisense, which is used for time-motion analysis in sports. Furthermore, some alternatives for positioning the system's transponders on the atheletes, as well as the accuracy depending on the location of measurement, were tested. Therefore, in a pre-study, some basic issues were examined (measurement assumptions and consistency and location of the system's transponder used for position detection), and position measurements at the borders and in the centre of a basketball field were performed...

It has been shown that the critical power (CP) in cycling estimated using a novel 3-min all-out protocol is reliable and closely matches the CP derived from conventional procedures. The purpose of this study was to assess the predictive validity of the all-out test CP estimate. We hypothesised that the all-out test CP would be significantly correlated with 16.1-km road time-trial (TT) performance and more strongly correlated with performance than the gas exchange threshold (GET), respiratory compensation point (RCP) and VO2 max...

PURPOSE OF THE STUDY: Comparisons have been often made between bone-tendon-bone plasty and hamstring tendon four-strand plasty. Whether a lateral tenodesis should be associated with the intra-articular reconstruction and the appropriate time between the accident and the repair remain two topics of debate. We present results obtained in a consecutive series of 50 pivoting sport atheletes reviewed retrospectively. These patients had been treated within eight days of trauma with a modified MacIntosh technique using an iliotibial band...

Anterior impingement syndrome is a generally accepted diagnosis for a condition characterized by anterior ankle pain with limited and painful dorsiflexion. The cause can be either soft tissue or bony obstruction. We reviewed 26 (16 male and 10 female) athletes with a mean age of 27 years treated arthroscopically for symptoms due to soft-tissue (group I, n = 12) and bony obstruction (group II, n = 14). They suffered from anterior pain, reduction of dorsiflexion and recurrent swelling with severe impairment in their sports activities...

OBJECTIVES: To evaluate the effect of exercise to osteoporosis by bone mineral density (BMD) measurement of athelets comparing normal individuals in general population. METHODS: BMD of radium, lumber spine, and femoral neck were measured by single photon absorptiometry (SPA), quantitative CT (QCT), and dual X-ray absorptiometry (DXA) respectively in athletes (n = 162, male 79, female 83) and age matched non-athletes normal population (n = 204, male 91, female 113) in Beijing...

Power athletes abuse anabolic androgenic steroids (AASs) and growth hormone (GH) to gain their muscular mass and strength. We wanted to determine how massive, self-administered doses of AASs with or without GH affect the left ventricular (LV) dimensions in power athletes. These substances are assumed to increase LVmass mainly by thickening the ventricular walls. Anecdotal evidence suggests a higher risk of cardiovascular events in AAS abusers. We were interested to see if LV dimensions and function in AAS abusers would indicate this increased risk...

Owing to the variability of injury, a mechanism of injury other than external rotation of the foot should not rule out a high ankle sprain. One must consider syndesmotic injury in the differential diagnosis of common ankle sprains and trauma. A high index of suspicion must lead the physician through clinical and radiographic examinations. Early and appropriate treatment of a high ankle sprain can greatly decrease a prolonged return to activity. Patients, especially competitive atheletes, must be educated regarding the morbidity of the condition...

Management theorists have long sought to identify precisely what makes some people flourish under pressure and others fold. But they have come up with only partial answers: rich material rewards, the right culture, management by objectives. The problem with most approaches is that they deal with people only from the neck up, connecting high performance primarily with cognitive capacity. Authors Loehr and Schwartz argue that a successful approach to sustained high performance must consider the person as a whole...

A 21-year-old man developed painful hyperkeratotic, fissured, callosities on his knuckles ("knuckle pads") after having boxed for five evenings a week for six months. Boxer's knuckle pads are one type of traumatic skin injury regularly found in athletes, such as "jogger's toe", "athelete's nodule", "jog-ger's nipple", "runner's rump", "runner's bump", "rower's rump", "tennis toe", "skier 's shin", "surfer's nodule" "black heel", "black palm", "jazz ballet bottom" and "stria distensae". These types of traumatic skin injuries are briefly reviewed here...

An Athletic Image Scale including female physiques with and without muscular definition is currently in the developmental phase. With shading, contouring, and three-dimensionality not offered previously on figure-rating scales, this instrument was designed to examine an apparent growing interest on the part of women in atheletic body-image ideals. The athletic level of each figure on the scale was based on responses of a group of college women. The 30-figure pilot scale was then tested by rating current and ideal body-shape preferences of two groups of first-year college women, 65 who exercised regularly and 45 who engaged in no regular exercise...

To obtain more information on the effects of long-lasting endurance and strength training on the constituents of the blood, several haematological and iron-related parameters were measured at rest in 39 male athletes from the Polish team who participated in the Olympics in Seoul in 1988. The athletes were divided into two groups: endurance-trained subjects (group E, cyclists, canoeists and rowers; n = 22) and strength-trained subjects (group S, wrestlers and judo; n = 17). The control group was composed of untrained male subjects (n = 48)...

Exercise-associated cardiac asystole (EACA) in patients without structural heart disease is uncommonly encountered. Two patients who developed prolonged asystolic arrest associated with exercise are described; both demonstrated a positive head-up tilt table response, absence of underlying heart disease, and a history of vagotonia. A review of this condition in the literature suggests the occurrence of this syndrome of EACA in young men with atheletic inclination who developed syncope usually after a strenuous exercise at a high heart rate...
