Abstract Introduction Cardiopulmonary exercise testing (CPEX) provides valuable diagnostic and prognostic cardiopulmonary function data. However, in clinical setting a maximal test is not always achievable. The Oxygen Efficiency Uptake Slope (OUES) has been proposed as possible submaximal measure of it remains relatively stable during the final quartile test. This study explored validity OUES s...

The main purpose of the note is to exclude existence certain submaximal curves in fake projective planes. This will lead lower bounds on multipoint Seshadri constants `fake' $\mathcal{O}(1)$

OBJECTIVES To compare the submaximal exercise capacity of polio subjects with postpoliomyelitis syndrome (PPS) and without (non-PPS) with that of healthy control subjects, to investigate the relationship of this capacity with maximal short-term power and quadriceps strength, and to evaluate movement economy. DESIGN Cross-sectional survey. SETTING University hospital. PARTICIPANTS Forty-th...

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...

Exercise is now considered an important component of management in chronic heart failure (CHF), but little is known about central hemodynamic changes that occur during different exercise modalities in these patients. Seventeen patients (ejection fraction 25 +/- 2%) undertook brachial artery and right heart catheterization and oxygen consumption assessment at rest, during submaximal and peak cyc...

Repeated bouts of submaximal exercise are an important part of most pulmonary rehabilitation programmes. Patients with moderate-to-severe cystic fibrosis (CF) often demonstrate oxygen desaturation during submaximal exercise, which may limit their ability to participate in these programmes. This study examines whether arterial desaturation contributes to submaximal exercise limitation by testing...

This study evaluated the hypothesis that active muscle blood flow is lower during exercise at a given submaximal power output after aerobic conditioning as a result of unchanged cardiac output and blunted splanchnic vasoconstriction. Eight untrained subjects (4 men, 4 women, 23-31 yr) performed high-intensity aerobic training for 9-12 wk. Leg blood flow (femoral vein thermodilution), splanchnic...

Submaximal and maximal physiological parameters were measured on a progressive treadmill test in 11 Columbia University tracksen trained for various events. All runners were also tested in the 22C, 440, 880, one-mile, and two -rile running events. Oxygen uptake was significantly related only to time in the one-mile run. Heart rates (HRs) at each submaximal load on the treadmill were significant...

PURPOSE It was investigated to what extent control signals used by human subjects to perform submaximal vertical jumps are related to control signals used to perform maximal vertical jumps. METHODS Eight subjects performed both maximal and submaximal height jumps from a static squatting position. Kinematic and kinetic data were recorded as well as electromyographic (EMG) signals from eight le...
