The aim of this study was to determine the prevalence of self- reported versus diagnosed stress fractures in female elite athletes and non-athletic controls. A random sample of Norwegian elite athletes from the national teams, aged 13-39 years (n = 186) and a random sample of non-athletic controls (n = 145) in the same age group participated in the study. The athletes represented a junior- or s...

Due to chronic dissatisfaction with body weight in youth, efforts to lose weight often lead to pathological dietary behaviours. Regular and heavy sports activity may contribute to the optimization of body weight, not only by elevating the energy utilization but also by increasing the health consciousness and the tendency to self-monitor. Research generally finds a beneficial role of extracurric...

We investigated the effect of sports activity on physically-disabled individuals using behavioral and electrophysiological techniques. Visual go/no-go discriminative and simple response tasks were used. Participants included 17 disabled athletes, 9 from open-skill (wheelchair basketball) and eight from closed-skill (swimming) sports, and 18 healthy non-athletes. Reaction times of the disabled a...

AIM Consumption of soy isoflavones reduces the risk of estrogen-related diseases, such as menopausal symptoms, osteoporosis, and cardiovascular disease. Equol is metabolized from the isoflavone daidzein by intestinal bacteria and has higher bioavailability than other isoflavones. Equol producers are believed to benefit from soybean consumption to a greater extent than non-producers. Recently, w...

AIMS This study was undertaken to evaluate the epidemiological features and the prognostic implications of syncope in young athletes. METHODS AND RESULTS A cohort of 7568 young athletes (5132 males, 2436 females, aged 16.2 +/- 2.4) underwent a pre-participation evaluation. A syncopal spell in the last 5 years was reported by 474 athletes (6.2%). Syncope was unrelated with exercise in 411 athl...

It has been suggested that athletes with longer fingers and larger hand surfaces enjoy stronger grip power. Therefore, some researchers have examined a number of factors and anthropometric variables that explain this issue. To our knowledge, the data is scarce. Thus, the aim of this study was to investigate the effect of hand dimensions, hand shape and some anthropometric characteristics on han...

This study examined the association between goal orientations and mental toughness and its influence on performance outcomes in competition. Wushu athletes (n = 40) competing in Intervarsity championships in Malaysia completed Task and Ego Orientations in Sport Questionnaire (TEOSQ) and Psychological Performance Inventory (PPI). Using cluster analysis techniques including hierarchical methods a...

INTRODUCTION AND OBJECTIVE Heat stress induces the expression of genes encoding heat-shock proteins and immune response mediators. The aim of this study was to determine the differences in the expression of genes encoding heat-shock proteins 70 kDa and27 kDa, interleukin 6, interleukin 10and C-reactive protein, between athletes and non-athletes after sauna bathing. MATERIALS AND METHOD Athlet...

AIMS The relative role of multiple determinants of left atrial volume index (LAVi) in athletes and non-athletes is not fully defined. Thus, we decided to prospectively assess the determinants of LAVi in healthy individuals and competitive athletes over a wide age range. METHODS AND RESULTS Four hundred and eighteen healthy individuals (mean age 41.7 ± 15.6 years, range 16-84, 65% males, 38% c...
