Clinical utility of urine specific gravity, electrical conductivity, and color as on‐farm methods for evaluating urine concentration in dairy cattle

Journal of Veterinary Internal Medicine, 2019
Background Urine concentration (UC) provides clinically useful information concerning hydration status and renal function of animals. Objectives To characterize the clinical performance of urine specific gravity measured by optical refractometry (USG‐R ...

Thermoregulatory and blood responses during exercise at graded hypohydration levels

, 1985
We studied the effects of graded hypohydration levels on thermoregulatory and blood responses during exercise in the heat. Eight heat-acclimated male subjects attempted four heat-stress tests (HSTs).

The Importance of Optimal Hydration in Patients with Heart Failure—Not Always Too Much Fluid

Biomedicines, 2023
Heart failure (HF) is a leading cause of morbidity and mortality and a major public health problem. Both overhydration and dehydration are non-physiological states of the body that can adversely affect human health. Congestion and residual congestion are

Effect of internal and external cooling on high‐intensity intermittent cycling performance and cognitive function in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of internal and external cooling on high‐intensity intermittent cycling performance and cognitive function in the heat. Twenty‐nine males completed a control trial (CON) and a cooling trial (ice slurry and ice collar; COOL) in the heat (33°C, 50% relative humidity) involving a 40 min intermittent cycling protocol ...

Effect of foot immersion and neck cooling on renal, intestinal, immune and inflammatory markers in older adults exposed to extreme heat

Experimental Physiology, EarlyView.
Abstract Older adults with reduced thermoregulatory capabilities are increasingly at risk of heat‐related pathophysiological outcomes (e.g., acute kidney injury, heatstroke) due to increasingly frequent, prolonged and intense heatwaves. Foot immersion and neck cooling have been proposed as practical, non‐electrical cooling strategies for protecting ...

Impact of dehydration on perceived exertion during endurance exercise: A systematic review with meta-analysis

Journal of Exercise Science & Fitness, 2022
Background/Objective: Understanding the impact of stressors on the rating of perceived exertion (RPE) is relevant from a performance and exercise adherence/participation standpoint. Athletes and recreationally active individuals dehydrate during exercise.
