In elite soccer, players are frequently required to play consecutive matches interspersed by 3 days and complete physical performance recovery may not be achieved. Incomplete recovery might result in underperformance and injury. During congested schedules, recovery strategies are therefore required to alleviate post-match fatigue, regain performance faster and reduce the risk of injury. This article [...]
ISSUE ADDRESSED: Many studies world wide have provided evidence that older persons are a sub-population at increased risk of heat-related morbidity and mortality. This article gives an overview of the current state of knowledge of risk factors and provides commentary on the role of health promotion in the prevention of a climate change-related increase in [...]
BACKGROUND: Muscle contraction during short intervals of intense exercise causes oxidative stress, which can play a role in the development of overtraining symptoms, including increased fatigue, resulting in muscle microinjury or inflammation. Recently it has been said that hydrogen can function as antioxidant, so we investigated the effect of hydrogen-rich water (HW) on oxidative stress [...]
Water balance control is aimed at normalizing cellular hydration, and sodium balance control at normalizing extracellular volume. Water balance control is based on the regulation of body fluid tonicity, while the control of sodium balance is based on the regulation of effective arterial volume. Disorders of water balance act on cellular hydration: primary disorders induce [...]
Vitamin D(3) has been called the "sunshine" vitamin since the formation of vitamin D is mediated by exposure to sunlight. Vitamin D(3) is linked to many health benefits, however serum levels of vitamin D(3) have been decreasing over the last few decades and the lower levels of vitamin D(3) may have consequences on normal physiology. [...]
Sweat is produced during exercise to help dissipate some of the extra heat produced due to an increase in metabolic rate. Inadequate drink ingestion during exercise means athletes finish exercise hypohydrated and when the time between exercise bouts is short, effective rehydration strategies will be necessary to prevent subsequent performance impairment. For complete rehydration, drink [...]
The purpose of this article is to review the effects of chronic mild dehydration and fluid consumption on specific health outcomes including obesity. The electronic databases PubMed and Google Scholar were searched for relevant literature published from the time of their inception to 2011, with results restricted to studies performed on human subjects and reports [...]
During prolonged exercise, fluid and salt losses through sweating reduce plasma volume which leads to heart rate drift in association with hyperthermia and reductions in performance. Oral rehydration with water reduces the loss of plasma volume and lessens heart rate drift and hyperthermia. Moreover, the inclusion of sodium in the rehydration solution to levels that [...]
What is already known about this subject: Few studies addressing the relationship between food consumption and cardiovascular disease or metabolic risk have been conducted in children. Previous findings have indicated greater metabolic risk in children with high intakes of solid hydrogenated fat and white bread, and low consumption of fruits, vegetables and dairy products. What [...]
Background: Early identification and treatment of dehydration is prudent in patients requiring home parenteral nutrition (HPN) or home intravenous fluids (HIVF) to prevent hospital admissions for dehydration. Our home nutrition support service (HNS) developed a protocol in 2010 to provide additional bags of HIVF to be kept on hand for immediate use in patients identified [...]
