BACKGROUND: Marathon running has become popular, particularly among inexperienced runners. HYPOTHESIS: Many marathoners are inexperienced and lack concern for potential complications of marathon running. STUDY DESIGN: Cross-sectional survey. METHODS: In sum, 419 runners completed a survey on a variety of topics regarding training for a marathon and hydration strategies. RESULTS: Overall, 211 females (38.3 ± [...]
This study determined the fluid balance of elite female basketball players before and during competition. Before and during 2 international games, 17 national-level players (age 24.2 ± 3 yr, height 180.5 ± 6 cm, mass 78.8 ± 8 kg) were assessed. Fluid-balance assessment included pregame hydration level as determined by urine specific gravity (USG), change [...]
Aim: The purpose of this study was to demonstrate the effectiveness of intermittent fluid infusion (intermittent rehydration therapy) to dehydrated elderly patients and the efficacy of Heisei Solution Water (HSW), an oral and enteral rehydration solution developed by our group. Methods: We enrolled 375 elderly patients with suspected dehydration from among 1,921 patients of our [...]
PURPOSE: The aim of this pilot study was to describe the hydration and nutritional status of a cohort of elderly dialysis patients and to explore the association between these parameters and the quality of life (QoL). METHODS: All patients over 75 years of age being in chronic dialysis by January 2008 at 3 dialysis units (n = 34) [...]
The purpose of this study was to examine if anticipatory sweating occurs prior to fluid consumption in dehydrated subjects. It was hypothesized that there would first be an anticipatory response to the sight of water, and then with drinking, a second response caused by mechanical stimulation of oropharyngeal nerves. Dehydrated subjects (n=19) sat in a [...]
Scars are well known to have a stratum corneum (SC) that is malfunctional. Increases in transepidermal water loss and decreases in SC capacitance and conductance have been reported. Occlusion therapy is a well-known route to improving the signs and symptoms of scarring. Until recently that has been assumed to be totally pressure related. However, studies [...]
A clinical link exists between severe dehydration and cognitive performance. Using rapid and severe water loss induced either by intense exercise and/or heat stress, initial studies suggested there were alterations in short-term memory and cognitive function related to vision, but more recent studies have not all confirmed these data. Some studies argue that water loss [...]
BACKGROUND: Although studies have investigated the effects of hydration on performance measures, few studies have investigated how the temperature of the ingested liquid affects performance and core temperature during an exercise session. The hypothesis of the present study was that cold water would improve thermoregulation and performance as measured by bench repetitions to fatigue, broad [...]
The cardiovascular response to standing (sit-to-stand change in heart rate; SSΔHR) is commonly employed as a screening tool to detect hypohydration (body water deficit). No study has systematically evaluated SSΔHR cut points using different magnitudes or different types of controlled hypohydration. The objective of this study was to determine the diagnostic accuracy of the often [...]
