Download or read book Waterlogged written by Timothy Noakes and published by Human Kinetics. This book was released on 2012-05-01 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Drink as much as you can, even before you feel thirsty." That's been the mantra to athletes and coaches for the past three decades, and bottled water and sports drinks have flourished into billion-dollar industries in the same short time. The problem is that an overhydrated athlete is at a performance disadvantage and at risk of exercise-associated hyponatremia (EAH)--a potentially fatal condition. Dr. Tim Noakes takes you inside the science of athlete hydration for a fascinating look at the human body’s need for water and how it uses the liquids it ingests. He also chronicles the shaky research that reported findings contrary to results in nearly all of Noakes’ extensive and since-confirmed studies. In Waterlogged, Noakes sets the record straight, exposing the myths surrounding dehydration and presenting up-to-date hydration guidelines for endurance sport and prolonged training activities. Enough with oversold sports drinks and obsessing over water consumption before, during, and after every workout, he says. Time for the facts—and the prevention of any more needless fatalities.

Download or read book The Effect of Fluid Balance on Exercise Performance in the Heat written by Yasuki Sekiguchi and published by . This book was released on 2016 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: In dehydrated individuals thirst seems to disappear after ingestion of small amount of water before full rehydration. This phenomenon has been linked to oropharyngeal receptors. However, some researchers suggest that drinking to satisfy thirst is enough for optimal performance. It is well established that water deficit greater than 2% of body weight decreases exercise performance in the heat. No study has ever examined the effect hydration on exercise performance in the absence of thirst via oropharyngeal stimulation. Purpose: The purpose of this study is to examine the effect of dehydration on exercise performance and thermoregulation during exercise in the heat independently of thirst. Method: Five competitive male cyclists (age, 31.6±4.9 y, weight, 74.7±3.7 kg, height, 180.9±4.3 cm, VO2peak, 57.5±28 mL{u2219}min-1{u2219}kg-1) were performed 2 hours cycling in 35°C and 30% relative humidity after that they completed 5K time trial. Two experimental trials were performed: on Dehydration without Thirst (DEH): drinking 25 ml water every 5 min with no infusion in the nasogastric tube, and the other was euhydration not thirst (EUH): drinking 25 ml water every 5 min while infusing in the nasogastric tube enough fluid to match sweat losses. Results: Sweat rate during 5K time trial in the EUH trial (2.2±0.7 L/h) was higher than that in the DEH trial (1.9±0.1 L/h). In the EUH trial, % body weight loss (-0.1±0.3 %) was lower than that in the DEH trial (-2.2±0.2 %) during 2 hours cycling. The finishing time of the 5K in the EUH trial was faster than that in the DEH trial (12.9±0.5 and 13.4±0.5 min). Core temperature at the end of the 5K time trial in the EUH trial was lower than that in the DEH trial (39.0±0.1 and 39.5±0.8 {u02DA}C). Mean skin temperature during the 5K time trial in the EUH trial was higher than that in the DEH trial. In both trials, there was no difference in the degree of thirst. Conclusion: In the EUH group, subjects completed faster the 5K time trial than in the DEH, probably due to lower thermoregulatory strain and better cardiovascular function.
