Teacher:Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.
Teacher: Now, understand the problem? Solve this instance: Exercise-trained hypoestrogenic premenopausal women with functional hypothalamic amenorrhea (ExFHA) exhibit impaired endothelial function. The vascular effects of an acute bout of exercise, a potent nitric oxide stimulus, in these women are unknown.', 'Three groups were studied: recreationally active ExFHA women (n = 12; 24.2 1.2 years of age; mean SEM), and recreationally active (ExOv; n = 14; 23.5 1.2 years of age) and sedentary (SedOv; n = 15; 23.1 0.5 years of age) ovulatory eumenorrheic women. Calf blood flow (CBF) and brachial artery flow-mediated dilation (FMD) were evaluated using plethysmographic and ultrasound techniques, respectively, both before and 1 hour after 45 minutes of moderate-intensity exercise. Endothelium-independent dilation was assessed at baseline using glyceryl trinitrate. Calf vascular resistance (CVR) and brachial peak shear rate, as determined by the area under the curve (SRAUCpk), were also calculated.', 'FMD and glyceryl trinitrate responses were lower (P < .05) in ExFHA (2.8% 0.4% and 11.6% 0.7%, respectively) than ExOv (8.8% 0.7% and 16.7% 1.3%) and SedOv (8.0% 0.5% and 17.1% 1.8%). SRAUCpk was also lower (P < .05) in ExFHA. Normalization of FMD for SRAUCpk (FMD/SRAUCpk) did not alter (P > .05) the findings. CBF was lower (P < .05) and CVR higher (P < .05) in ExFHA. After exercise, FMD and SRAUCpk were augmented (P < .05), but remained lower (P < .05), in ExFHA. FMD/SRAUCpk no longer differed (P > .05) between the groups. CBF in ExFHA was increased (P < .05) and CVR decreased (P < .05) to levels observed in ovulatory women.
