• orthostatic tolerance
  • The combined exercise regime seemed to maintain the capacity to carry out a certain degree of endurance exercise (aerobic exercise capacity) and helped at the end of the bed-rest period to preserve orthostatic tolerance, i.e. the ability to change posture to an upright stance without feeling faint. (esa.int)
  • In addition, he evaluated the pathophysiology of Chronic Orthostatic Intolerance (COI, or Postural Orthostatic Tachycardia Syndrome) and the changes in orthostatic tolerance following long term bed rest (ESA, European Space Agency project). (hunimed.eu)
  • constant
  • Fechner's general formula for getting at the number of units in any sensation is S = c log R, where S stands for the sensation, R for the stimulus numerically estimated, and c for a constant that must be separately determined by experiment in each particular order of sensibility. (wikipedia.org)
  • The haemodynamic consequences of this vascular dilatation and permeability lead to a state of relative hypovolemia with a constant stimulus for fluid and salt conservation by the kidneys. (wikipedia.org)
  • undergo
  • During the 20 days following the bed-rest period they will undergo similar tests for comparison with the baseline data. (esa.int)
  • During the 20-day rehabilitation period following bed-rest, the test subjects will undergo tests similar to those before the bed-rest period, for comparison with the baseline data. (esa.int)
  • psychological
  • He is also credited with demonstrating the non-linear relationship between psychological sensation and the physical intensity of a stimulus via the formula: S = K ln ⁡ I {\displaystyle S=K\ln I} , which became known as the Weber-Fechner law. (wikipedia.org)
  • WISE
  • WISE needs 24 female volunteers altogether, who will remain in bed for a total duration of 60 days. (esa.int)
  • immobilization
  • Also, due to the inherent immobilization that is experienced in flotation REST (by not being able to roll over), which can become uncomfortable after several hours, the subject is unable to experience the session durations of chamber REST. (wikipedia.org)
  • days
  • For the 20 days prior to the bed rest period, the test subjects will take part in the collection of baseline data. (esa.int)
  • hospital
  • Symptoms can be produced by solitary confinement, loss of sight or hearing, paralysis, and even by ordinary hospital bed rest. (thefreedictionary.com)
  • Wanting to give the boys the highest survival rate possible they monitored the fluid for any sign of infection and had me lying on back on bed rest in the hospital. (glimpsesofskiff.com)
  • subjects
  • Fewer than 5% of the subjects tested leave before the session duration ends, which is usually around an hour for flotation REST. (wikipedia.org)
  • Infusion of epinephrine to reproduce exercise circulating concentrations of epinephrine in subjects at rest has little haemodynamic effect, other than a small β2-mediated fall in diastolic blood pressure. (wikipedia.org)
  • bone
  • What it all comes down to in terms of recovery (or preventing bone loss) is a balance between stress and rest . (letsrun.com)
  • allow
  • This may not allow the subject to experience the changes in attitudes and thinking that are associated with chamber REST. (wikipedia.org)
  • room
  • In chamber REST, the subject lies on a bed in a completely dark and sound-reducing (on average, 80 dB) room for up to 24 hours. (wikipedia.org)
  • In flotation REST, the room contains a tank or pool. (wikipedia.org)
  • patients
  • Bed rest has been an established treatment in the past prescribed for critically illness or convalescing patients, in order to preserve their body metabolic resource, to prevent serious complications and to support their rapid path to recovery. (frontiersin.org)
  • These results suggest that an impairment of the rapid PKC/CPI-17 signaling pathway downstream of α-adrenoceptors in peripheral arterial constriction, as an end organ of orthostatic blood pressure reflex, is associated with OH in prolonged bed rest patients. (ebscohost.com)
  • technique
  • Ever since the validation of the tissue velocity echocardiography (TVE) technique more than a decade ago the modality has been used rather successfully in various clinical situations, at rest as well as during stress echocardiography. (diva-portal.org)
  • state
  • Since one of the main results of chamber REST is a state of relaxation, the effects of chamber REST on arousal are less clear-cut, which can be attributed to the nature of the solution. (wikipedia.org)
  • below
  • All participants in the first of two campaigns have been lying in bed, tilted head down at an angle of 6º below horizontal, so that their heads are slightly lower than their feet. (esa.int)
  • All 12 female participants are now lying in bed tilted head down at an angle of 6º below horizontal, so that their heads are slightly lower than their feet. (esa.int)
