Maximal oxygen intake estimated from submaximal heart rate.
This study investigated the predictability of maximal oxygen intake from three different submaximal heart rates assessed during an initial and follow-up ride on a cycle ergometer. Twenty-four healthy male subjects performed workloads of 600, 750, and 900 kpm's for six minutes on each of two visits to the laboratory. Analysis of variance for a randomised complete blocks design, with subjects con...
متن کاملHemodynamic Determinants of Maximal Oxygen Intake
Fourteen patients with a healed myocardial infarction (no angina pectoris) had maximal oxygen intake (VO0 max) determinations and hemodynamic studies at submaximal and maximal exercise levels; seven patients were studied two months after an acute myocardial infarction (untrained group) while seven had followed a physical training program for 13.5 months (trained group). At the maximal exercise ...
متن کاملAre heart rate dynamics in the transition from rest to submaximal exercise related to maximal cardiorespiratory responses in COPD?
BACKGROUND Poor exercise capacity is an important negative prognostic marker in patients with chronic obstructive pulmonary disease (COPD). Heart rate variability (HRV) responses can indicate alterations in cardiac autonomic control. Nevertheless, it remains unclear whether these abnormalities are related to cardiorespiratory responses to exercise in these patients. OBJECTIVE To evaluate whet...
متن کاملEffects of nitroglycerin on "maximal" oxygen intake and exercise electrocardiogram in coronary heart disease.
same test, after each individual rested 30 min and took 0.4 mg nitroglycerin sublingually, increased V02 max in patients with angina (by 14.5%, P <0.001) and in patients with prior infarction (by 6%, P < 0.005) but not in healthy persons. Angina at VO2 max was prevented in 12 patients. Maximal heart rate was increased by 11% in the angina group and by 4% in the myocardial infarction group; the ...
متن کاملAnalysis of Heart Rate Variability During Submaximal Exercise
an increased mortality in patients recovering from myocardial infarction. The effects that physiologic perturbations such as exercise have on this heart rate variability have not been investigated. Therefore, heart rate variability was measured throughout a submaximal exercise test in 36 mongrel dogs with healed anterior myocardial infarctions. The amplitude of the respiratory component (0.24-1...
