Cerebral metabolic response to submaximal exercise.
We studied cerebral oxygenation and metabolism during submaximal cycling in 12 subjects. At two work rates, middle cerebral artery blood velocity increased from 62 +/- 3 to 63 +/- 3 and 70 +/- 5 cm/s as did cerebral oxygenation determined by near-infrared spectroscopy. Oxyhemoglobin increased by 10 +/- 3 and 25 +/- 3 micromol/l (P < 0. 01), and there was no significant change in brain norepinep...
متن کاملBlood Pressure Response to Submaximal Exercise Test in Adults
Background. The assessment of blood pressure (BP) response during exercise test is an important diagnostic instrument in cardiovascular system evaluation. The study aim was to determine normal values of BP response to submaximal, multistage exercise test in healthy adults with regard to their age, gender, and workload. Materials and Methods. The study was conducted in randomly selected normoten...

eventually found). Arterial plasma NA was 6.4 f 2.3 nmol/l; the arterial AD was 1.03 k 0.46 nmol/l. In the adrenal vein, these concentrations were greater by 7. I f 3.4 nmol/l and 45.3 f 12.2 nmol/l respectively. Hepatic and renal venous AD concentrations were much lower, by 0.61 f 0.23 nmol/l and 0.67 f 0.12 nmol/l; for NA. the hepatic a-v difference was 5.3 f 1.9 nmol/l, but the renal a-v dif...
متن کاملHeritability of submaximal exercise heart rate response to exercise training is accounted for by nine SNPs.
Endurance training-induced changes in hemodynamic traits are heritable. However, few genes associated with heart rate training responses have been identified. The purpose of our study was to perform a genome-wide association study to uncover DNA sequence variants associated with submaximal exercise heart rate training responses in the HERITAGE Family Study. Heart rate was measured during steady...
متن کاملA Study on the Serum Levels of Angiogenic Factors in Response to Acute Long-term Submaximal Exercise in Sedentary Men
Introduction: Exercise training increases skeletal muscle capillary density, but the molecular mechanisms of this process are not yet clear. The aim of the present study was to investigate the effect of acute long- term submaximal exercise on serum vascular endothelial growth factor (VEGF) as the main angiogenic factor, and matrix metalloproteinases 2 and 9 ( MMP-2 and MMP-9), as the degradi...
