INTRODUCTION Heart rate variability and resting metabolic rate are commonly to assess athlete's physiological status and energy requirements. Exercise-induced dehydration can reach up to 5% of body mass per hour. Consequently, dehydration may have a profound physiological effect on human's homeostasis. OBJECTIVES To compare the effects of dehydration and rehydration after exercise on heart ra...

Using intravenous infusion, we separated the physiologic consequences of 3% body mass dehydration from the conscious awareness of fluid replacement on time trial (TT) performance in the heat. Eleven trained cyclists performed 90 min of steady-state (50% V ˙ O 2 peak ) cycling followed by a self-paced 20-km TT in a hot-dry (35 °C, 10% relative humidity, wind speed 3.0 m/s) environment while euhy...

Dehydration in the neonatal period has many causes. Dehydration is classified as isotonic, hypotonic, or hypertonic, based on the serum osmolality that in most cases is reflected in the serum sodium level. Hypernatremic dehydration is usually caused by gastroenteritis, but it can also be caused by salt poisoning or diabetes insipidus. This type of dehydration can be especially dangerous. The hy...

Our paper introduces the research and development of a new, continuously operational food dehydrator, prototype said machine. Conditions related to heating technology are required for dehydrators that prevent vegetables fruits from suffering too much damage their internal components. In new system, traditional convective heat transfer was combined with microwave dehydration, which is well-known...

introduction: neonatal hypernatremia dehydration (nhd) is a dangerous condition in neonates, which is accompanied by acute complications (renal failure, cerebral edema, and cerebral hemorrhage) and chronic complications (developmental delay). children begin learning language from birth, and hearing impairment interferes with this process. we assessed the hearing status of infants with hypernatr...

The purpose of this study was to examine the in vitro dehydration characteristics of new and worn conventional and silicone-hydrogel contact lenses. Four contact lens materials were investigated: three conventional hydrogels (etafilcon, nelfilcon, omafilcon) and one silicone-hydrogel (narafilcon). Gravimetric data were obtained with analytical balance with 1 min intervals. Quantitative paramete...

Dehydration in clinical practice, as opposed to a physiological definition, refers to the loss of body water, with or without salt, at a rate greater than the body can replace it. We argue that the clinical definition for dehydration, ie, loss of total body water, addresses the medical needs of the patient most effectively. There are 2 types of dehydration, namely water loss dehydration (hypero...
