OBJECTIVE To examine the effects of a single session of isometric physical exercise on postprandial triglyceridemia in sedentary male individuals with fasting triglycerides values < 150 mg/dl (NTG) or > " 150 mg/dl (TG ALT). METHODS Twenty-seven individuals (10 NTG and 17 TG ALT), aged between 30-55 years were assessed in the study. Triglycerides were determined in the beginning, and at two, ...

The objective of the study was to determine the effects of acute high-intensity interval training (HIIT) on hematological parameters in sedentary men. Ten healthy, non-smoker, and sedentary men aged between 18 and 24 years participated in the study. All subjects performed four Wingate tests with 4 min intervals between the tests. Blood samples were collected at pre-exercise, immediately after, ...

Baroreflex buffering plays an important role in arterial blood pressure control. Previous reports suggest that baroreflex sensitivity may be altered in endurance exercise-trained compared with untrained subjects. It is unknown, however, if in vivo baroreflex buffering is altered in the endurance exercise-trained state in humans. Baroreflex buffering was determined in 36 healthy normotensive men...

&nbsp;&nbsp;Background: The balance between production of Reactive Oxygen Species (ROS) and antioxidant defense in the body has important health implications. The aim of this study was to investigate the changes in salivary antioxidants: catalase, vitamin C and brain-derived neurotrophic factor (BDNF), in sedentary men at rest and after acute exhaustive exercise. &nbsp; Methods: This randomi...

COITAL ANGINA IS ANGINA THAT occurs during the minutes or hours following sexual activity. More than 6 million individuals in the United States experience angina pectoris. Coital angina appears to represent less than 5% of all anginal attacks. For various reasons, fewer middle aged or older women engage in sexual activity than age-matched men. Accordingly, the prevalence of coital angina is hig...

OBJECTIVE To investigate the association between physical activity (PA) and sedentary lifestyle (SL) patterns with overweight (OW), obesity (OB), abdominal obesity (AO) and cardiometabolic comorbidities in Greek adults based on data from the National Epidemiological Survey for the prevalence of obesity. DESIGN Cross-sectional epidemiological survey. Participants were selected via stratified s...

BACKGROUND We investigated the associations between education and leisure-time, occupational, sedentary and total physical-activity levels based on data from the German National Health Interview and Examination Survey 1998 (GNHIES98). The roles of income level, occupational status and other mediating variables for these associations were also examined. METHODS The total study sample of the GN...

BACKGROUND Falls affect approximately one third of community-dwelling older adults each year and have serious health and social consequences. Fear of falling (FOF) (lack of confidence in maintaining balance during normal activities) affects many older adults, irrespective of whether they have actually experienced falls. Both falls and fear of falls may result in restrictions of physical activit...

Since females have a greater prevalence of obesity compared with males, the question arises whether females have lower metabolic rate than males after adjusting for differences in body weight and composition. 24-h energy expenditure (24EE), basal metabolic rate (BMR), and sleeping metabolic rate (SMR) were measured in a respiratory chamber in 235 healthy, nondiabetic Caucasian subjects (114 mal...
