Different studies have suggested that the majority of self-talk during exercise is either positive or neutral in character. The majority of 'thoughts' during low-intensity exercise have been described as being dissociative conversational chatter. However, with increasing exercise intensity, there is a greater percentage of associative and motivational thoughts, which includes ...

Studies suggest that physical fitness promotes cardiovascular health, including improved endothelial function and possibly reduced inflammatory responses to stressors. This study examined the effects of fitness on leukocyte-endothelial adhesion in response to an acute exercise challenge. Peripheral blood mononuclear cell (PBMC) adhesion to human umbilical venous endothelial cells (HUVEC) was ...

We hypothesize a mechanism for reinforcing transitions between levels of selection, involving physiological homeostasis and amplification of variation in the physical environment. Groups experience a stronger selection pressure than individuals for homeostasis with respect to reproductively limiting variables, because their greater longevity exposes them more often to suboptimal physical conditions, ...

BACKGROUND: Elevated C-reactive protein (CRP) is a risk factor for atherosclerosis. Cardiorespiratory fitness, the ability of active skeletal muscle to utilize oxygen during aerobic exercise, can be impaired by atherosclerotic changes peripherally affecting the vasculature or centrally perturbing the heart and coronary arteries. However, the association between cardiorespiratory fitness and ...

Variables associated with physical activity show circadian rhythms in resting subjects; these rhythms have both exogenous (due to the individual's lifestyle and environment) and endogenous (due to the "body clock") components. During exercise, many of the rhythms persist, even though some show decreasing amplitude with increasing severity of exercise. Whilst ...

In territorial polygynous taxa, reproductive success reflects phenotypic variation. Using Crotaphytus collaris, a sexually dimorphic lizard in which males use the head (i.e., jaws and associated musculature) as a weapon when territorial interactions escalate to fights, we tested the hypothesis that weapon performance (i.e., bite force) is a better predictor ...

Physical functioning in patients with end-stage renal disease treated with dialysis is low, whether measured using objective laboratory measures, physical performance testing, or self-reported measures. Peak oxygen uptake (VO2peak), self-reported functioning measures, and physical activity levels are independent predictors of mortality in these patients. Cardiovascular exercise training studies result in ...
