This study investigated the psychometric nature of preference for and tolerance exercise intensity in physical activity. It initially re-examined Preference Tolerance Intensity Exercise Questionnaire (PRETIE-Q) among Portuguese exercisers, looking at its applicability to different activities experiences. Then, investigate measure groups, invariance was examined. The sample consisted 1117 partic...

The purpose of this study was to determine the effects of phlebotomy on the exercise tolerance and right and left ventricular ejection fraction of polycythemic patients with chronic obstructive pulmonary disease. Ten patients with COPD (mean FEV1 = 1.32 +/- 0.55 L) and polycythemia (mean Hct = 62 +/- 3 percent) were studied before and after their hematocrits had been reduced to approximately 50...

Treatment with vasodilators in heart failure has not always produced a useful improvement in the haemodynamic responses to exercise, and in many cases early drug tolerance has further limited the potential of this type of treatment. In a study to evaluate the efficacy of felodipine, a new calcium antagonist with selective vasodilator properties, in the management of congestive heart failure 10 ...

BACKGROUND Although high exercise tolerance is associated with an excellent prognosis, the significance of abnormal myocardial perfusion imaging (MPI) in patients with high exercise tolerance has not been established. This study retrospectively compares the utility of MPI and exercise ECG (EECG) in these patients. METHODS AND RESULTS Of 388 consecutive patients who underwent exercise MPI and ...

Introduction. Respiratory cancer and its treatment are known to contribute to muscle weakness and functional impairment. Aim. To assess the effects of rehabilitation in patients with respiratory cancer. Methods. Radically treated respiratory cancer patients were included in a 12-week multidisciplinary rehabilitation program. Results. 16 patients (age: 61 ± 7 years; FEV(1): 57 ± 16% pred.) showe...

We studied the effect of a single oral dose of 40 mg of pentaerythritol tetranitrate (PETN) on the exercise capacity of ten patients with angina pectoris. The study design was a randomized double-blind crossover comparing the effects of 40 mg of oral PETN with placebo on exercise tolerance. Patients were exercised to moderate angina pectoris before and 2 1/2 and 4 1/2 hours after receiving the ...

BACKGROUND Heart rate reduction should benefit patients with chronic stable angina by improving myocardial perfusion and reducing myocardial oxygen demand. This study evaluated the antianginal and antiischemic effects of ivabradine, a new heart rate-lowering agent that acts specifically on the sinoatrial node. METHODS AND RESULTS In a double-blind, placebo-controlled trial, 360 patients with ...

Prediabetes is defined as impaired fasting glucose and/or impaired glucose tolerance. Impaired fasting glucose is usually defined as fasting blood glucose between 5.6 mmol/L and 6.9 mmol/L (100.8-124.2 mg/dL), and impaired glucose tolerance is the 2-hour oral glucose tolerance test of 7.8-11.0 mmol/L (140.4-198.0 mg/dL). Most individuals with prediabetes are overweight or obese and are at great...

It is commonly held that the respiratory system has ample capacity relative to the demand for maximal O(2) and CO(2) transport in healthy humans exercising near sea level. However, this situation may not apply during heavy-intensity, sustained exercise where exercise may encroach on the capacity of the respiratory system. Nerve stimulation techniques have provided objective evidence that the di...
