Amplitude modulation of the soleus H-reflex in the human during walking and standing.
Experiments were done to determine the amplitude of the monosynaptically mediated H-reflex of the soleus muscle at various phases of the step cycle, using a computer-based analysis procedure. In all subjects tested the amplitude of the H-reflex was strongly modulated in amplitude during the walking cycle and was highest during the stance phase. In many subjects the peak reflex amplitude occurre...
متن کاملComparion of Standing Posture Control between Pre and Post Head out Water Immersion
The effects of autonomic nervous system by head-out water immersion at thermoneutral temperature will also influence the standing posture control. This study aimed to compare variations in posture control ability after standing from the water immersion at thermoneutral temperatures for healthy young Japanese adults. The healthy male college students (n=5) participated in this study. The body co...
متن کاملEffect of aging on carotid artery stiffness and baroreflex sensitivity during head-out water immersion in man.
To examine the possible age-related blood pressure (BP) deregulation in response to central hypervolemia, we measured spontaneous baroreflex sensitivity (SBRS), carotid arterial compliance (CC), and R-R interval coefficient of variation (RRICV) during basal and thermoneutral resting head-out-of-water immersion (HOWI) in 7 young (YG = 24.0 +/- 0.8 years) and 6 middle-aged/older (OL = 59.3 +/- 1....
متن کاملPeripheral chemosensitivity is not blunted during 2 h of thermoneutral head out water immersion in healthy men and women
Carbon dioxide (CO2) retention occurs during water immersion, but it is not known if peripheral chemosensitivity is altered during water immersion, which could contribute to CO2 retention. We tested the hypothesis that peripheral chemosensitivity to hypercapnia and hypoxia is blunted during 2 h of thermoneutral head out water immersion (HOWI) in healthy young adults. Peripheral chemosensitivity...
متن کاملCirculating opioid peptides during water immersion in normal man.
1. This study was designed to evaluate variations in plasma beta-endorphin, methionine-enkephalin, adrenocorticotropic hormone and serum prolactin in healthy volunteers during head-out water immersion. 2. Water immersion induced an increase in methionine-enkephalin plasma levels, which was associated with a significant fall in mean arterial pressure and heart rate. 3. Conversely, a suppression ...
