Water: a neglected nutrient in the young child? A South African perspective

WaterÂ is considered an essentialÂ nutrientÂ because the body cannot produce enoughÂ waterÂ itself, by metabolism of food, to fulfil its need. When the quantity or quality ofÂ waterÂ is inadequate, health problems result, most notably dehydration and diarrhoea. As a result of contaminatedÂ waterÂ and poor hygiene, related infections are still a serious problem. Indeed, in theSouthÂ AfricanÂ settingÂ waterÂ availability and sanitation are critical issues because [...]

Fluid and electrolyte balance in ultra-endurance sport.

It is well known that fluid and electrolyte balance are critical to optimal exercise performance and, moreover, health maintenance. Most research conducted on extreme sporting endeavour (>3 hours) is based on case studies and studies involving small numbers of individuals. Ultra-endurance sportsmen and women typically do not meet their fluid needs during exercise. However, successful [...]

Metabolic and thermodynamic responses to dehydration-induced reductions in muscle blood flow in exercising humans

1. The present study examined whetherÂ reductionsÂ inÂ muscleÂ bloodÂ flowÂ with exercise-induced dehydration would reduce substrate delivery and metabolite and heat removal to and from active skeletal muscles during prolonged exercise in the heat. A second aim was to examine the effects of dehydration on fuel utilisation across theÂ exercisingÂ leg and identify factors related to fatigue. 2. Seven cyclists performed two [...]

Effect of fluid ingestion on muscle metabolism during prolonged exercise.

Five trained men were studied during 2 h of cycling exercise at 67% peak oxygen uptake at 20-22 degrees C to examine the effect of fluid ingestion on muscle metabolism. On one occasion, the subjects completed this exercise without fluid ingestion(NF) while on the other they ingested a volume of distilled deionized water that prevented [...]

THERMOREGULATORY RESPONSES AND HYDRATION PRACTICES IN HEAT-ACCLIMATIZED ADOLESCENTS DURING PRESEASON HIGH SCHOOL FOOTBALL

Previous researchers have not investigated the thermoregulatory responses to multiple consecutive days of American football in adolescents. OBJECTIVE: To examine the thermoregulatory and hydration responses of high school players during formal preseason football practices. DESIGN: Observational study. SETTING: Players practiced outdoors in late August once per day on days 1 through 5, twice per day [...]

PHYSICAL ACTIVITY, FOOD INTAKE, AND BODY WEIGHT REGULATION: INSIGHTS FROM DOUBLY LABELED WATER STUDIES

Body weight and energy balance can be maintained by adapting energy intake to changes in energy expenditure and vice versa, whereas short-term changes in energy expenditure are mainly caused by physical activity. This review investigates whether physical activity is affected by over- and undereating, whether intake is affected by an increase or a decrease in [...]

EXERCISE IN A HOT ENVIRONMENT: COMPARISON OF TWO DIFFERENT FLUID INTAKE PATTERNS

Aim. Extensive research has been undertaken in the area of exercise and hydration. Most work has focused on prehydration. Less is known about different fluid intake patterns during exercise and its effect in thermoregulatory variables in hot environments. This study attempted to determine if ingesting fluid either in a single bolus or intermittently during exercise [...]

HYDRATION, HYDRATION, HYDRATION

Throughout the world, large numbers of manual workers perform physically demanding labour in conditions of high environmental heat stress. Although the importance of adequate hydration in combating heat stress is universally recognized, studies in a range of worker groups have demonstrated a disturbingly poor hydration level in a high proportion of at-risk workers. Management of [...]

FUNCTIONAL SKIN ADAPTATION IN INFANCY – ALMOST COMPLETE BUT NOT FULLY COMPETENT

Early postnatal life is a period of active functional reorganization and cutaneous physiological adaptation to the extrauterine environment. Skin as the outermost organ of mammalians is endowed of multiple functions such as protection, secretion, absorption and thermoregulation. Birth stimulates the epidermal barrier maturation and the skin surface acidification especially in premature infants. In full-term infants [...]
