Influence of Hypohydration on Intermittent Sprint Performance in the Heat [PDF]
International Journal of Sports Physiology and Performance, 2009 Purpose:To examine the effect of hypohydration on physiological strain and intermittent sprint exercise performance in the heat (35.5 ± 0.6°C, 48.7 ± 3.4% relative humidity).Methods:Eight unacclimatized males (age 23.4 ± 6.2 y, height 1.78 ± 0.04 m, mass 76.8 ± 7.7 kg) undertook three trials, each over two days.

Hypohydration impairs endurance performance: a blinded study [PDF]
Physiological Reports, 2017 The general scientific consensus is that starting exercise with hypohydration >2% body mass impairs endurance performance/capacity, but most previous studies might be confounded by a lack of subject blinding. This study examined the effect of hypohydration in a single blind manner using combined oral and intragastric rehydration to manipulate hydration

The Impact of Hydration on Metabolic Outcomes: From Arginine-Vasopressin Signaling to Clinical Implications [PDF]
MedicinaArginine-vasopressin peptide (AVP) plays a critical role in water balance and osmoregulation. However, emerging evidence suggests that AVP’s actions may expand beyond its traditional role, significantly influencing metabolic regulation, including glucose

It's just how we do it: social processes in rapid weight loss for combat sports [PDF]
Health Psychology and Behavioral MedicineMaking weight is an essential aspect of preparation for competition in combat sports. In addition to gradual weight loss in order to fight lean, fighters commonly engage in Rapid Weight Loss (RWL) practices seeking short-term hypohydration in order to be

Hypohydration Increases Heart Rate Despite Preserved Hemodynamic Compensation During Blood Flow Restricted Exercise. [PDF]
Scand J Med Sci SportsABSTRACT During blood flow restriction (BFR) exercise, blood becomes sequestered in the active limbs due to impeded venous return, contributing to central hypovolemia. Dehydration also reduces blood volume and can exacerbate the ability of the cardiovascular (CV) system to defend against CV stressors, such as exercise and orthostatic stress.

Assessment of the MX3 hydration testing system in adults at rest and following exercise in the heat. [PDF]
Physiol RepAbstract This study examined the performance of MX3 hydration testing system for assessing hydration status at rest and following exercise. Twenty adults completed two matched exercise trials in warm‐humid conditions. Pre‐ and post‐exercise saliva osmolality (Sosm) were assessed using MX3.

Obesity, but not hypohydration, mediates changes in mental task load during passive heating in females [PDF]
PeerJ, 2018 Background The independent effects of hypohydration and hyperthermia on cognition and mood is unclear since the two stresses often confound each other.

Pain Across the Menstrual Cycle: Considerations of Hydration
Frontiers in Physiology, 2020 Chronic pain – pain that persists for more than 3 months – is a global health problem and is associated with tremendous social and economic cost. Yet, current pain treatments are often ineffective, as pain is complex and influenced by numerous factors ...
