Little is known about how women who exercise during pregnancy are perceived. The purpose of this study was to investigate whether the positive exercise stereotype (i.e., the general tendency for exercisers to be evaluated more positively than nonexercisers) extends to pregnancy. Adult women (N = 202, mean age = 38.55 ...

Aim:  In recent years blood sphingolipids attracted much attention and have been implicated in both pathophysiology and prevention of cardiovascular diseases and insulin resistance. However, factors affecting concentration and metabolism of sphingolipids in blood remain poorly recognized. We have previously found that exercise alters skeletal muscle sphingolipid metabolism. This finding ...

For most of human history, the environmental demands of survival necessitated prodigious amounts of physical exertion. The avoidance of predators, hunting, gathering, and the literal "chopping wood and carrying water" of daily existence provided a wholesome dose of physical activity that obviated the need for deliberate exercise. Nevertheless, 21st century ...

It was recently demonstrated that musculoarticular (MA) stiffness is related to sprint cycling performance in nonfatigued conditions. This study examined whether relatively stiffer cyclists were more effective at sprinting under fatigued conditions, as occurs during endurance cycling competitions. MA stiffness of the quadriceps was assessed in 21 trained male cyclists ...

Exercise adaptations result from a coordinated response of multiple organ systems, including cardiovascular, pulmonary, endocrine-metabolic, immunologic, and skeletal muscle. Among these, the cardiovascular system is the most directly affected by exercise, and it is responsible for many of the important acute changes occurring during physical training. In recent years, the ...

Research regarding the benefits of exercise for cardiovascular and metabolic health is extensive and well-documented. However, weight-bearing exercise may not be suitable for individuals with orthopaedic or musculoskeletal limitations, excess adiposity or other medical conditions. Water-based exercise may provide an attractive alternative to land-based exercise for achieving improved health and ...

Physical activity, exercise training, and fitness are associated with decreased cardiovascular risk. In the context that a risk factor "gap" exists in the explanation for the beneficial effects of exercise on cardiovascular disease, it has recently been proposed that exercise generates hemodynamic stimuli which exert direct effects on the vasculature ...

We have shown previously that combined short-arm centrifuge and aerobic exercise training preserved several physiologically important cardiovascular functions in humans. We hypothesized that artificial gravity (AG) and exercise is effective to prevent changes of physical problems during head-down bed rest (HDBR). To test this hypothesis, 12 healthy male subjects had ...

Dynamic exercise evokes sustained blood pressure and heart rate (HR) increases. Although it is well accepted that there is a CNS mediation of cardiovascular adjustments during dynamic exercise, information on the role of specific CNS structures is still limited. The bed nucleus of the stria terminalis (BST) is involved in ...

Current studies intimate the fetal cardiovascular and respiratory systems benefit from exercise throughout pregnancy. These changes persist after birth suggesting that exercise exposure has long-term health benefits lasting into adulthood. Individuals exposed to exercise in utero show no signs of cardiovascular disease (CVD) as adults. Considering the pandemic of CVD ...
