BACKGROUND It is not clear what the relative contribution is of specific components of physical fitness (aerobic and muscular) to cardiovascular disease (CVD) risk. We investigated associations between aerobic fitness (endurance) and muscular fitness (power) and CVD risk factors. METHODS Data were obtained from the Young Hearts project, a representative sample of 12- and 15-year-old boys and ...

parathyroid hormone (pth) is the major factor of calcium homeostasis. this hormone increases calcium uptake in intestines through stimulation of the active formation of vitamin d and eventually increases bone density. the aim of this study was to investigate the effect of one session of resistance and endurance activity on pth and alp in untrained young girls (mean age 21.9±1.23 yrs, height 161...

We determined the site-specific relations of hormone replacement therapy (HRT) and habitual exercise status with intima-media thickness (IMT) in both elastic (carotid) and muscular (femoral) arteries in 77 healthy postmenopausal women: 43 women were sedentary (20 no-HRT and 23 HRT users) and 34 women were endurance trained (14 no-HRT and 20 HRT users). Femoral IMT was not different among the se...

Seven older cyclists (mean age 66.9 years) still engaged in severe endurance training (mean = 8114.3 km year-1) were examined medically, echocardiographically and they underwent a maximal stress test on a bicycle. Mean maximal values were VO2,max = 44.7 ml, Wmax = 261.4 and heart rate = 157.4 beats min-1. The heart volume/max O2-pulse ratio (mean = 46.1) and the TEDD/max O2-pulse ratio (mean = ...

The aim of the study was to assess the impact of motor abilities and morphological characteristics on junior judoka performance. A set of 14 morphological parameters and a set of 14 motor tests as predictor variables, and 3 variables evaluating judo performance as criteria were applied in a sample of 40 judoists aged 17 years +/-6 months. Three factors were isolated by factor analysis in morpho...

Endurance impact exercise, e.g., running, is known to enhance the intestinal calcium absorption. However, nonimpact exercise, e.g., swimming, is more appropriate for osteoporotic patients with cardiovascular diseases or disorders of bone and joint, but the effect of swimming on the intestinal calcium transport was unknown. This study, therefore, aimed to investigate the transepithelial calcium ...

BACKGROUND Athletic training leads to remodelling of both left and right ventricles with increased myocardial mass and cavity dilatation. Whether changes in cardiac strain parameters occur in response to training is less well established. In this study we investigated the relationship in trained athletes between cardiovascular magnetic resonance (CMR) derived strain parameters of cardiac functi...
