Nitric oxide synthase inhibition does not affect the exercise-induced arterial hypoxemia in Thoroughbred horses.
Because sensitivity of equine pulmonary vasculature to endogenous as well as exogenous nitric oxide (NO) has been demonstrated, we examined whether endogenous NO production plays a role in exercise-induced arterial hypoxemia. We hypothesized that inhibition of NO synthase may alter the distribution of ventilation-perfusion mismatching, which may affect the exercise-induced arterial hypoxemia. A...
متن کاملCardiovascular and respiratory responses in Thoroughbred horses during treadmill exercise.
Six detrained Thoroughbred horses performed incremental treadmill tests. Maximal oxygen uptake (VO2max) was measured during exercise by analysis of expired gas. The relationships between oxygen consumption (VO2) and work rate, heart rate (HR), cardiac output (Q), stroke volume (SV) and arteriovenous oxygen content difference [C(a-v)O2] were examined during submaximal and maximal exercise. The r...
متن کاملExercise-induced arterial hypoxemia.
Exercise-induced arterial hypoxemia (EIAH) at or near sea level is now recognized to occur in a significant number of fit, healthy subjects of both genders and of varying ages. Our review aims to define EIAH and to critically analyze what we currently understand, and do not understand, about its underlying mechanisms and its consequences to exercise performance. Based on the effects on maximal ...
متن کاملSevere exercise-induced hypoxemia.
Exercise training is an essential component of pulmonary rehabilitation and is associated with improved function and other important outcomes in persons with chronic lung disease. A subset of pulmonary rehabilitation patients experience hypoxemia that may occur or worsen with exercise. For the purpose of this review, severe exercise-induced hypoxemia is defined as an S(pO(2)) of < 89% during e...
متن کاملProfiling of exercise-induced transcripts in the peripheral blood cells of Thoroughbred horses
Transcriptome analyses based on DNA microarray technology have been used to investigate gene expression profiles in horses. In this study, we aimed to identify exercise-induced changes in the expression profiles of genes in the peripheral blood of Thoroughbred horses using DNA microarray technology (15,429 genes on 43,603 probes). Blood samples from the jugular vein were collected from six hors...
