Abstract Objective To explore the adversity- and growth-related experiences of swimmers at the highest competitive level. Of particular interest was the transitional process that the swimmers progress through to positively transform their experiences. Design Eight autobiographies of Olympic swimming champions were sampled and analyzed. Method The books were written by four male and three female swimmers whose ages at the time of their Olympic swims ranged from 14 to 41 years ( M = 23.39, SD = 6....

A number of studies have now examined the association between smoking and the magnitude of physiological reactions to acute psychological stress. However, no large-scale study has demonstrated this association incorporating neuroendocrine in addition to cardiovascular reactions to stress. The present study compared neuroendocrine and cardiovascular reactions to acute stress exposure in current smokers, ex-smokers, and those who had never smoked in a large community sample. Salivary cortisol, sys...

In this study we examined changes in the salivary concentrations of immunoglobulin A (sIgA), cortisol (sC), testosterone (sT), and testosterone-to-cortisol ratio (T/C) in 21 competitive swimmers, 11–15 years old, during a week leading to competition as compared to a control (noncompetition) week. No day-to-day changes or significant differences between weeks were observed for sIgA ( versus μg/mL for control versus competition week, resp.), sC ( versus ng/mL for control versus competition week, r...

Several endocrine parameters commonly measured in plasma, such as steroid hormones, can be measured in the oral fluid. However, there are several technical aspects of saliva sampling and processing that can potentially bias the validity of salivary testosterone measurement. The aim of this study was to evaluate the effects caused by repeated sampling; 5 min centrifugation (at 2000, 6000 or 10,000g); the stimulation of saliva flow by a cotton swab soaked in 2% citric acid touching the tongue; dif...

Background: In order to achieve world-class performances, regular performance diagnostics is required as an essential prerequisite for guiding high performance sport. In high performance swimming, the lactate performance diagnostic is an important instrument in testing the sport specific endurance capacity. Although the role of lactate as a signaling molecule, fuel and a gluconeogenic substrate is accepted, lactate parameters are discussed concerning stability, explanatory power and interpretabi...

Summary Testosterone concentrations rise rapidly in the context of competitive interactions and remain elevated in winners relative to losers. Theoretical models suggest that this divergent neuroendocrine response serves to mediate future dominance behaviours. Although research in animal models provides compelling support for this model, evidence for its applicability to human social behaviour is limited. In the current study, men and women were randomly assigned to experience a series of victor...

Abstract Objectives To summarize the major accomplishments of research on the relationship between exercise and affect over the past five decades and to outline an expanded research agenda for the future. Design Literature review. Method Illustrative and historically significant publications on the exercise–affect link were examined. Results The main accomplishments over the past fifty years include (a) a growing recognition that exercise can have a positive and clinically meaningful influence o...

The peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α) controls metabolic adaptations. We now show that PGC-1α in skeletal muscle drives the expression of lactate dehydrogenase (LDH) B in an estrogen-related receptor-α–dependent manner. Concomitantly, PGC-1α reduces the expression of LDH A and one of its regulators, the transcription factor myelocytomatosis oncogene. PGC-1α thereby coordinately alters the composition of the LDH complex and prevents the increase in blood lactate...

Current knowledge of the relationship between the HPA axis and physical exercise in normal and highly trained individuals highlights the importance of adequate preparation for exercise. The activation of the HPA (hypothalamic–pituitary–adrenal) axis in response to physical activity in humans has been abundantly reported. The HPA axis consists of three structurally independent components including the hypothalamus, the anterior pituitary, and the adrenal cortex. These structures are intimately in...

People with higher levels of emotional intelligence (EI: adaptive emotional traits, skills and abilities) typically achieve more positive life outcomes, such as psychological wellbeing, educational attainment, and job-related success. Although the underpinning mechanisms linking EI with those outcomes are largely unknown, it has been suggested that EI may work as a ‘stress buffer’. Theoretically, when faced with a stressful situation, emotionally intelligent individuals should show a more adapti...
