Mechanisms of orthostatic intolerance following very prolonged exercise.
Nine men completed a 24-h exercise trial, with physiological testing sessions before (T1, approximately 0630), during (T2, approximately 1640; T3, approximately 0045; T4, approximately 0630), and 48-h afterwards (T5, approximately 0650). Participants cycled and ran/trekked continuously between test sessions. A 24-h sedentary control trial was undertaken in crossover order. Within testing sessio...
متن کاملOrthostatic intolerance: postural orthostatic tachycardia syndrome with overlapping vasovagal syncope.
A 28-year-old female with a history of situational syncope and a new-onset right sided hemiparesis is described. Tilt-up table test revealed the postural orthostatic tachycardia syndrome followed by vasovagal syncope. Neurological and internal medicine tests showed no particular disorders. The patient underwent autonomic physical training and the tilt-up test performed three months later showed...
متن کاملCardiac function following prolonged exercise: influence of age.
This study sought to determine the influence of age on the left ventricular (LV) response to prolonged exercise (PE; 150 min). LV systolic and diastolic performance was assessed using echocardiography (ECHO) before (pre) and 60 min following (post) exercise performed at 80% maximal aerobic power in young (28 ± 4.5 years; n = 18; mean ± SD) and middle-aged (52 ± 3.9 years; n = 18) participants. ...

متن کاملSyndromes of orthostatic intolerance and syncope in young adults
OBJECTIVE To explore the clinical and neuroendocrine characteristics of syndromes of orthostatic intolerance and syncope in young adults. METHODS Two hundred and thirty-six patients aged 18-40 years with orthostatic intolerance and/or syncope were examined by head-up tilt test (HUT). Plasma levels of epinephrine, norepinephrine, renin, C-terminal-pro-arginine-vasopressin (CT-proAVP), C-termin...
