Abstract Background: Vertical head-out water immersion has different physiological effects on the human body system due to hydrostatic pressure and temperatures. This review examines changes in cerebral blood flow metabolism during in-water exercise Method: Systematic research was conducted PubMed, ScienceDirect, Scopus databases, by binary methods. It included 11 articles that met inclusion cr...
Diving and decompression performed under immersed conditions have been shown to reduce cardiac function. The mechanisms for these changes are not known. The effect of immersion before a simulated hyperbaric dive on cardiomyocyte function was studied. Twenty-three rats were assigned to four groups: control, 1 h thermoneutral immersion, dry dive, and 1 h thermoneutral immersion before a dive (pre...
UNLABELLED The aim of this study was to assess the volume and function of human brown adipose tissue (BAT) in vivo using MR imaging. METHODS BAT volumes under thermoneutral conditions in the cervical areas were assessed via water-fat contrast using the Dixon method and via water-saturation efficiency using fast spin-echo and T2-weighted images. The existence of cervical BAT was also assessed ...
PURPOSE To examine the effects of a whole-body cryotherapy (WBC) protocol (3 min at -110°C) on acute recovery and key variables of endurance performance during high-intensity intermittent exercise in a thermoneutral environment. METHODS Eleven endurance athletes were tested twice in a randomized crossover design in which 5×5 min of high-intensity running (HIR) were followed by 1 h of passive ...
When exposed to extreme cold or injected with the alpha(2)-adrenoceptor agonist, clonidine, infant rats emit ultrasonic vocalizations (USVs). Based upon the cardiovascular changes that accompany these two manipulations, especially decreased venous return, it was hypothesized that USVs are the acoustic by-product of the abdominal compression reaction (ACR), a maneuver that increases venous retur...
