conclusions acute l-carnitine supplementation possibly affects exercise performance and triglycerides in athletes rather than sedentary men. objectives this study aimed to investigate the acute effects of l-carnitine supplementation on aerobic metabolic efficiency and lipid profiles in sedentary and athletic men. methods fifteen sedentary (20.4 ± 1.5 years) and 15 athletic (21.5 ± 2.4 years) me...

BACKGROUND Sedentary behaviours are increasingly recognised as raising the risk of cardiovascular disease events, diabetes and mortality, independently of physical activity levels. However, little is known about patterns of sedentary behaviour in older adults. METHODS Cross-sectional study of 1566/3137 (50% response) men aged 71-91 years from a UK population-based cohort study. Men wore a GT3...

BACKGROUND Sedentary behavior is associated with poor well-being in youth with adverse trajectories spanning to adulthood. Still, its determinants are poorly known. Our aim was to profile sedentary and non-sedentary young men and to clarify their differences in a population-based setting. METHODS A total of 616 men (mean age 17.9, SD 0.6) attending compulsory conscription for military service...

The occurrence of ventricular arrhythniias during exercise testing, jogging, and sedentary life with and without preceding exercise was studied with the aid of ambulatory electrocardiographic monitoring in healthy physically active men, healthy sedentary men, and men with previous myocardial infarction (15 men in each group). Ventricular premature beats of the same grade were found during exerc...

As a main basis of health, the mental health is required for a good, efficient, and satisfactory personal life. The aim of this study was to compare the mental health and its subscales between elderly men in athletic, active, and sedentary groups. Therefore, we examined 150 elderly men in three groups of athletes, active, and sedentary and proceeded to complete the questionnaires. We administer...

We determined the independent and interactive influences of aging and habitual endurance exercise on calf venous compliance in humans. We tested the hypotheses that calf venous compliance is 1) reduced with age in sedentary and endurance-trained men, and 2) elevated in young and older endurance-trained compared with age-matched sedentary men. We studied 8 young (28 +/- 1 yr) and 8 older (65 +/-...

In sedentary individuals, H(1) receptors mediate the early portion of postexercise skeletal muscle hyperemia, whereas H(2) receptors mediate the later portion. It is not known whether postexercise hyperemia also presents in endurance-trained individuals. We hypothesized that the postexercise skeletal muscle hyperemia would also exist in endurance-trained individuals and that combined blockade o...

BACKGROUND AND AIMS We investigated whether objectively measured sedentary time was associated with markers of inflammation in adults with newly diagnosed type 2 diabetes. METHODS AND RESULTS We studied 285 adults (184 men, 101 women, mean age 59.0 ± 9.7) who had been recruited to the Early ACTivity in Diabetes (Early ACTID) randomised controlled trial. C-reactive protein (CRP), adiponectin, ...

BACKGROUND Total sedentary time varies across population groups with important health consequences. Patterns of sedentary time accumulation may vary and have differential health risks. The purpose of this study is to describe sedentary patterns of older adults living in retirement communities and illustrate gender and age differences in those patterns. METHODS Baseline accelerometer data from...
