We hypothesize that regular exercise enhances antioxidative enzymes in pregnant women, which reduce oxidative stress and, thus, the incidence of preeclampsia. Oxidative stress with enhanced lipid peroxide formation could lead to endothelial dysfunction in preeclampsia. Other conditions, such as increased transferrin saturation and decreased iron-binding capacity, directly and indirectly promote...

BACKGROUND About half of women decrease their regular exercise during middle age. Concurrently, they experience a reduction in basal metabolic rate and loss of lean muscle as they transition to menopause. The combined effects place these women at increased risk for body weight gain and associated co-morbidities. Further research is required to better assess their barriers to regular exercise an...

Data from the trial known as Testosterone in Older Men with Mobility Limitations (TOM) has indicated an association between testosterone administration and a greater risk for adverse cardiovascular events. We therefore propose that regular exercise is a cardioprotective alternative that prevents detrimental changes in contractile activation when a deficiency in male sex hormones exists. Ten-wee...

Physical activity has long been considered beneficial to health and regular exercise is purported to relieve stress. However empirical evidence demonstrating these effects is limited. In this study, we compared psychophysiological responses to an acute psychosocial stressor between individuals who did, or did not, report regular physical exercise. Healthy men and women (N = 111) participated in...

BACKGROUND Little is known regarding the characteristics of elderly persons who do not regularly exercise. This lack of knowledge limits the design and marketing of exercise programs to persons who could benefit from regular exercise. METHODS We compared characteristics of regular exercisers and nonexercisers among 561 randomly selected persons aged 65 years and older who were enrollees of a ...

BACKGROUND/OBJECTIVES Physical exercise promotes energy producing pathways requiring thiamin and riboflavin as a coenzyme. Therefore, this study investigated the effects of regular exercise training on urinary excretion of thiamin and riboflavin. MATERIALS/METHODS Fifty rats were randomly assigned to one of two groups: non-exercise training (NT, n = 25) and regular exercise training (ET, n = ...

BACKGROUND Exercise is associated with major benefits in patients with rheumatic diseases for both cardiovascular and rheumatic status. However, information about exercise generally is not collected systematically in routine rheumatology care. A multidimensional health assessment questionnaire (MDHAQ), which was designed for busy clinical settings, includes a query about exercise status. We ana...

Background Endometriosis, defined by overgrowth of endometrial implants outside the uterine cavity, is commonly found on the ovaries. The role of exercise in this disease is not well understood. Regular exercise appears to have protective effects against endometriosis that involve inflammatory processes since it induces elevate systemic levels of inflammatory cytokines production with antioxida...

Background: Regular physical activity increases physical fi tness and lowers ventilation during mild and moderate exercise thereby reducing the likelihood of provoking exercise-induced asthma. Regular exercise may also reduce the perception of breathlessness through a number of mechanisms including strengthening respiratory muscles. Subjectively, many asthmatics report that they are symptomatic...
