Drift in Oxygen Consumption during Prolonged Sub-maximal Exercise in Subjects of Different Training Status

Myocardial oxygen consumption during exercise in fasting and lipemic subjects.

Phylogenetic analysis of mammalian maximal oxygen consumption during exercise.

We compiled published values of mammalian maximum oxygen consumption during exercise ( ) and supplemented these data with new measurements of for the largest rodent (capybara), 20 species of smaller-bodied rodents, two species of weasels and one small marsupial. Many of the new data were obtained with running-wheel respirometers instead of the treadmill systems used in most previous measurement...

Cardiovascular drift during prolonged exercise: new perspectives.

We propose that cardiovascular drift, characterized by a progressive decline in stroke volume after 10-20 min of exercise, is primarily due to increased heart rate rather tahn a progressive increase in cutaneous blood flow as body temperature rises.

Prolonged oxygen kinetics during early recovery from maximal exercise in adult patients with cystic fibrosis.

STUDY OBJECTIVES To explore the significance of oxygen kinetics during early recovery after maximal cardiopulmonary exercise testing (CPET) in the assessment of functional capacity and severity of the disease in cystic fibrosis (CF) patients. PARTICIPANTS Eighteen patients with CF (9 male/9 female; mean +/- SD age, 23 +/- 13 years) and 11 healthy subjects (3 male/8 female; mean age, 29 +/- 4 ...

Gender differences in the oxygen transport system during maximal exercise in hypertensive subjects.

STUDY OBJECTIVES To analyze gender differences in the oxygen transport system at peak exercise with particular emphasis on the difference in systemic arteriovenous oxygen extraction and in mixed venous oxygen saturation. PATIENTS AND METHODS Cardiopulmonary graded exercise testing and hemodynamic assessment were performed on a cycle ergometer in 64 hypertensive patients (32 female and 32 male...
