Fluid and fuel intake during exercise.
The amounts of water, carbohydrate and salt that athletes are advised to ingest during exercise are based upon their effectiveness in attenuating both fatigue as well as illness due to hyperthermia, dehydration or hyperhydration. When possible, fluid should be ingested at rates that most closely match sweating rate. When that is not possible or practical or sufficiently ergogenic, some athletes...
متن کاملMammalian fuel utilization during sustained exercise.
The 'crossover' and 'lactate shuttle' concepts of substrate utilization in humans during exercise are extended to describe metabolic responses on other mammalian species. The 'crossover concept' is that lipid plays a predominant role in sustaining efforts requiring half or less aerobic capacity (VO2max); however, greater relative efforts depend increasingly on blood glucose and muscle glycogen ...
متن کاملEffect of preexercise soup ingestion on water intake and fluid balance during exercise in the heat.
PURPOSE To determine whether chicken noodle soup before exercise increases ad libitum water intake, fluid balance, and physical and cognitive performance compared with water. METHODS Nine trained men (age 25 ± 3 yr, VO2peak 54.2 ± 5.1 ml · kg-1 · min-1; M ± SD) performed cycle exercise in the heat (wet bulb globe temperature = 25.9 ± 0.4 °C) for 90 min at 50% VO2peak, 45 min after ingesting 3...
متن کاملramadan and its effect on fuel selection during exercise and following exercise training
fasting induces short-term physiological adaptations which spare the body's remaining carbohydrate stores and mobilize lipid stores to provide a substitute fuel for many tissues and organs, especially skeletal muscle. rodent studies show that regular occurrence of fasting then refeeding, stimulates adaptations in muscle which make the animal better placed to withstand a further period of fastin...
متن کاملFluid intake during wheelchair exercise in the heat: effects of localized cooling garments.
BACKGROUND Wheelchair tennis players, competing in hot and humid environments, are faced with an increased risk of heat-related illness and impaired performance. This study examined the effects of head and neck cooling garments on perceptions of exertion (RPE), thermal sensation (TS), and water consumption during wheelchair exercise at 30.4 +/- 0.6 degrees C. METHODS Eight highly trained whee...
