چکیده

PURPOSE The purpose of this study was to determine if %Type I fibers and/or aerobic fitness (as peak .VO(2)) would predict Delta efficiency (DeltaEff) and Delta.VO(2)/Deltawork rate (WR) for moderate (below lactate threshold 0.05). CONCLUSION These results suggest that aerobic fitness affects the energetic response to changes in power output during moderate exercise, such that the more aerobically fit a subject, the greater the increase in oxygen cost (.VO(2)) (reduced efficiency) as work rate increases. Further, Delta.VO(2)/DeltaWR reflects the inverse of DeltaEff for moderate-intensity exercise in healthy fed subjects.

Skeletal muscle abnormalities and exercise intolerance in older patients with heart failure and preserved ejection fraction.

Heart failure (HF) with preserved ejection fraction (HFPEF) is the most common form of HF in older persons. The primary chronic symptom in HFPEF is severe exercise intolerance, and its pathophysiology is poorly understood. To determine whether skeletal muscle abnormalities contribute to their severely reduced peak exercise O2 consumption (Vo2), we examined 22 older HFPEF patients (70 ± 7 yr) co...

Effect of reduced body weight on muscle aerobic capacity in patients with COPD.

BACKGROUND Reduced muscle aerobic capacity in COPD patients has been demonstrated in several laboratories by phosphorus magnetic resonance spectroscopy and by analysis of oxygen uptake (VO2) kinetics. COPD patients are usually elderly, hypoxemic, poorly active with muscle atrophy, and often malnourished. Under these conditions there is usually reduction of O2 delivery to the tissues (bulk O2 fl...

Endurance training induces fiber type-specific revascularization in hindlimb skeletal muscles of rats with chronic heart failure

Objective(s): Previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. The aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. Materials and Methods: Four weeks after surgeries (left anterior descending (LAD) artery occlusion), chr...

Muscle capillarization O2 diffusion distance, and VO2 kinetics in old and young individuals.

The relationships between muscle capillarization, estimated O2 diffusion distance from capillary to mitochondria, and O2 uptake (VO2) kinetics were studied in 11 young (mean age, 25.9 yr) and 9 old (mean age, 66.0 yr) adults. VO2 kinetics were determined by calculating the time constants (tau) for the phase 2 VO2 adjustment to and recovery from the average of 12 repeats of a 6-min, moderate-int...

Adrenergic regulation of HSL serine phosphorylation and activity in human skeletal muscle during the onset of exercise.

Skeletal muscle hormone-sensitive lipase (HSL) activity is increased by contractions and increases in blood epinephrine (EPI) concentrations and cyclic AMP activation of the adrenergic pathway during prolonged exercise. To determine the importance of hormonal stimulation of HSL activity during the onset of moderate- and high-intensity exercise, nine men [age 24.3 +/- 1.2 yr, 80.8 +/- 5.0 kg, pe...
