Hemodynamic mechanisms of the attenuated blood pressure response to mental stress after a single bout of maximal dynamic exercise in healthy subjects
To determine the hemodynamic mechanisms responsible for the attenuated blood pressure response to mental stress after exercise, 26 healthy sedentary individuals (age 29 ± 8 years) underwent the Stroop color-word test before and 60 min after a bout of maximal dynamic exercise on a treadmill. A subgroup (N = 11) underwent a time-control experiment without exercise. Blood pressure was continuously...
متن کاملImpaired hemodynamic response to mental stress in subjects with prehypertension is improved after a single bout of maximal dynamic exercise
INTRODUCTION High blood pressure during mental stress in subjects with prehypertension is associated with blunted vasodilation in skeletal muscles, which might be improved by an acute bout of exercise. OBJECTIVE To investigate the hemodynamic responses to mental stress before and after a bout of exercise in subjects with prehypertension. METHOD Eighteen subjects with prehypertension and 16 ...
متن کاملCharacterization of Renal Glucose Reabsorption in Response to Dapagliflozin in Healthy Subjects and Subjects With Type 2 Diabetes
OBJECTIVE To examine the effect of dapagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, on the major components of renal glucose reabsorption (decreased maximum renal glucose reabsorptive capacity [TmG], increased splay, and reduced threshold), using the pancreatic/stepped hyperglycemic clamp (SHC) technique. RESEARCH DESIGN AND METHODS Subjects with type 2 diabetes (n=12) and m...
متن کاملIn Vivo Abdominal Aortic Hemodynamic Conditions at Rest and during Cycling Exercise in Young Healthy Subjects, Older Healthy Subjects, and Intermittent Claudication Patients
INTRODUCTION The human abdominal aorta, particularly at the infrarenal level, experiences higher prevalence of atherosclerosic lesions as compared to the thoracic aorta [1]. Localization of atherosclerotic lesions have been correlated with adverse hemodynamic conditions such as low flow, low wall shear stress (WSS), and high flow and shear oscillations [2]. Furthermore, elevated blood flow and ...
متن کاملMaximal values of sniff nasal inspiratory pressure in healthy subjects.
BACKGROUND Inspiratory muscle strength is often better reflected by oesophageal pressure during a maximal sniff (sniff POES) than by maximal inspiratory pressure (PImax). Sniff POES can be estimated non-invasively by measuring the sniff nasal inspiratory pressure (SNIP). The aim was to establish maximal normal values for the SNIP and to compare them with PImax. METHODS One hundred and sixty h...
