Dilation of the thoracic aorta is the primary risk factor for aortic dissection, a highly morbid and mortal condition with in-hospital mortality over 25%. Causal and often synergistic mediators of aortic dilation include sex, age, body size, hypertension, and inherited/congenital conditions such as Marfan syndrome and bicuspid aortic valve. However, these risk factors fail to explain the full e...

The aim of this study was to analyze blood lactate response before, during and after simulated taekwondo fight in young male athletes. The experiment was composed of simulated official taekwondo fight. During the experiment a total of 7 blood samples (25 μL) were collected that following: at rest, after 1st, 2nd, and 3rd rounds, and 3, 5, and 10 min after the end of combat. The results showed t...

[Purpose] The aim of this study was to analyze stabilometry in athletes during an indoor season in order to determine whether injured athletes show different stabilometric values before injury than non-injured athletes in two different training periods (volume and pre-competition periods). [Subjects] The subjects were 51 athletes from Unicaja athletic club who trained regularly. [Methods] At th...

The incidence of stress injuries in older athletes is increasing, associated with a more active older population. The same principles apply for its prevention and treatment, but older athletes usually present a more adverse outcome. It is mandatory to raise awareness to this common, but frequently neglected pathology.

attribution theory is one of the psychological dynamic theories that explainsand describes people's perception of facts. therefore, the aim of this research wasto study success and failure attributions in athletes and coaches. the population ofthis study consisted of athletes and coaches of national teams (elite) and clubteams (sub–elite) in swimming, badminton, karate, taekwondo, table te...

The purpose of this study was to determine if the HRindex Method (VO2max = [6 x HRindex - 5] x 3.5, where HRindex = HRmax/HRrest) was accurate for tracking changes in VO2max following 8-weeks of endurance training among collegiate female soccer players. Predicted VO2max via the HRindex Method and observed VO2max from a maximal exercise test on a treadmill were determined for a group of female s...

BACKGROUND The risk of infectious mononucleosis among athletes is quite debated. Some personal observations seem to suggest an increase risk of mononucleosis among athletes, because they attend always close settings with an high probability of respiratory pathogens transmission; overtraining has been also proposed as risk factor. STUDY DESIGN Cross-sectional study in a group of swimmers (aged...

CONTEXT Prolonged transmeridian air travel can impart a physical and emotional burden on athletes in jet lag and travel fatigue. Jet lag may negatively affect the performance of athletes. STUDY TYPE Descriptive review. EVIDENCE ACQUISITION A Medline search for articles relating to jet lag was performed (1990-present), as was a search relating to jet lag and athletes (1983-January, 2012). Th...

This investigation evaluated the effects of a 4-week, 12-session training program using resisted sprint training (RST), assisted sprint training (AST), and traditional sprint training (TST) on maximal velocity and acceleration in National Collegiate Athletic Association (NCAA) Division IA female soccer athletes (n = 27). The subjects, using their respective training modality, completed 10 maxim...

Dear Editor, I read with interest the paper by Chia and Aziz.1 Using allometric scaling, the authors adjusted peak oxygen uptake (VO2max) for the confounding influence of body mass and found that mass exponents differed markedly for male and female athletes. I believe the mass exponent generated for the female athletes is the suspect. In the first place, Chia regressed VO2max on body mass (Fig....
