PURPOSE To measure the choroidal thickness (CT) after dynamic exercise by using enhanced depth imaging optical coherence tomography (EDI-OCT). MATERIALS AND METHODS A total of 19 healthy participants performed 10 min of low-impact, moderate-intensity exercise (i.e., riding a bicycle ergometer) and were examined with EDI-OCT. Each participant was scanned before exercise and afterward at 5 min ...

OBJECTIVE To study the effects of nocturnal hypoxemia in patients with chronic obstructive pulmonary disease without obstructive sleep apnea syndrome. METHODS We studied 21 patients-10 desaturators and 11 nondesaturators-submitted to arterial blood gas analysis, polysomnography, spirometry, cardiopulmonary exercise testing (cycle ergometer), and hand-grip dynamometry, as well as measurements ...

BACKGROUND Although the bronchodilating effect of inhaled anticholinergics has been established in patients with chronic obstructive pulmonary disease (COPD), their effects on exercise capacity are still controversial. Previous studies have suggested that the standard dosage hardly affects exercise tolerance, whereas higher doses might elicit an improvement. The aim of the present study was to ...

This study investigated the effects of a low dose of nisoldipine (5 mg, p.o.) in 10 patients with ischemic heart disease. The patients were subjected to a 90-min exercise regimen before and after a 5 mg dose of nisoldipine, using a supine bicycle ergometer adjusted to each patient's limitations. The mean blood plasma level of nisoldipine was 3.8 +/- 3.1 (SD) ng/ml. The drug significantly decrea...

objective: exercise activity could be an amendment to polycystic ovary syndrome (pcos). however the acute and chronic effects of various exercise intensities on serum leptin levels are ambiguous. this study investigates the acute and chronic responses of various intensities of exercise on serum leptin levels and weights of female rats with pcos. methods: in this semi-empirical study, 80 adult w...

PURPOSE to compare the blood pressure and oxygen consumption (VO(2)) responses between pregnant and non-pregnant women, during cycle ergometer exercise on land and in water. METHODS ten pregnant (27 to 29 weeks of gestation) and ten non-pregnant women were enrolled. Two cardiopulmonary tests were performed on a cycle ergometer (water and land) at the heart rate corresponding to VO(2), over a ...

BACKGROUND The authors sought to evaluate the acceptability and feasibility of maximal fitness testing in sedentary older individuals at risk for mobility disability. METHODS Maximal cycle-ergometer testing was performed at baseline and 6 and 12 months later in a subset of LIFE-P study participants at the Cooper Institute site. The mean age of the 20 participants (80% female) tested was 74.7 ...

introduction: good functional capacity has a high negative predictive value (npv) in patients with known or suspected coronary artery disease (cad) similar to a normal gated myocardial perfusion imaging (gmpi). aim of this study was to evaluate npv of functional capacity during treadmill exercise in patients with normal gmpi in pakistani population. methods: this was a prospective study which ...
