Intravenous fluid use in athletes.

CONTEXT: Time allowing, euhydration can be achieved in the vast majority of individuals by drinking and eating normal beverages and meals. Important to the competitive athlete is prevention and treatment of dehydration and exercise-associated muscle cramps, as they are linked to a decline in athletic performance. Intravenous (IV) prehydration and rehydration has been proposed as [...]

Lack of awareness of fluid needs among participants at a midwest marathon.

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 ± [...]

Fluid balance of elite female basketball players before and during game play.

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 [...]

The effect of a cold beverage during an exercise session combining both strength and energy systems development training on core temperature and markers of performance.

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 [...]

Rosenbloom C.

Athletes who are properly fueled and hydrated before, during, and after exercise can improve training, increase performance, and decrease fatigue. Many commercial products are marketed to athletes and are designed to be consumed at specific periods: before, during, and after exercise. Are these products really necessary? This article reviews the research on nutrition support for [...]

“Pilot study: Effects of drinking hydrogen-rich water on muscle fatigue caused by acute exercise in elite athletes.”

"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 [...]

Sports nutrition knowledge among collegiate athletes, coaches, athletic trainers, and strength and conditioning specialists.

CONTEXT: Coaches, athletic trainers (ATs), strength and conditioning specialists (SCSs), and registered dietitians are common nutrition resources for athletes, but coaches, ATs, and SCSs might offer only limited nutrition information. Little research exists about sports nutrition knowledge and current available resources for nutrition information for athletes, coaches, ATs, and SCSs. OBJECTIVE: To identify resources of [...]

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 [...]

Effect of beverage osmolality on intestinal fluid absorption during exercise.

To determine how osmolality of an orally ingested fluid-replacement beverage would alter intestinal fluid absorption from the duodenum and/or jejunum during 85 min of cycle exercise (63.3 +/- 0.9% peak O2 uptake) in a cool environment (22 degreesC), seven subjects (5 men, 2 women, peak O2 uptake = 54.5 +/- 3.8 ml . kg-1 .

American College of Sports Medicine position stand. Exercise and fluidreplacement.

This Position Stand provides guidance on fluid replacement to sustain appropriate hydration of individuals performing physical activity. The goal of prehydrating is to start the activity euhydrated and with normal plasma electrolyte levels. Prehydrating with beverages, in addition to normal meals and fluid intake, should be initiated when needed at least several hours before the [...]
