Objectives, Discuss optimum hydration and effects of. dehydration on exercise, Discuss the best methods for fluid. replacement, Review the electrolyte composition of sports. Optimum Hydration, Performance decreases with water loss of 2 or. more of body weight, Prehydration prior to exercise helps avoid.
excessive losses during exercise goal to be, Measuring body weight prior to and after exercise. can estimate sweat rates, Electrolytes also need to be replaced more or less. depending on sweat rate and salt content, Major means of cooling the exercising body. Losses vary greatly person to person and with different types of activities. Electrolytes, Electrolytes must be replaced, Excessive salty sweating can lead to hyponatremia. increased losses with increased sweat rate and dehydration. Water loss sweat during exercise is dependent on, Exercise Intensity.
Ambient temperature and humidity, Body surface area body weight. Acclimatization, Metabolic efficiency in the exercise. Hourly Sweat Rates, 1 L of sweat loss, 1kg body weight loss. 580 kcal loss, Sweat Rates in Different Sports, ACSM Position Stand on Exercise and Fluid Replacement 2007. Measures of Hydration, ACSM Position Stand on Exercise and Fluid Replacement 2007.
Measures of Hydration, Can t rely on thirst dizziness headache. tachycardia dry mouth skin turgor to predict, dehydration. Effects of Dehydration on Performance, With dehydration increased strain and perceived exertion for. the same task, Exaggerated in warm hot conditions and with greater degree. of dehydration, Less effect of dehydration seen in cold conditions.
Dehydration 2 BW decreases aerobic performance, especially in warm hot conditions. Dehydration 2 BW may decrease mental cognitive, performance. Dehydration 3 5 BW doesn t decrease anaerobic, performance or muscle strength. Dangers of Impaired Fluid Balance, Dehydration, Increases risk for exertional heat illness. Muscle cramps salty sweaters, Increases risk for renal damage and.
rhabdomyolysis, Hyperhydration, Hyponatremia free water intake greater than sweat. loss or large sweat sodium losses, Exercise Associated Hyponatremia. First recognized in Comrades Marathon South, Africa reported in 1971. Associated with over drinking of hypotonic fluids, and or excessive salt loss. Athletes at higher risk women and older adults, smaller athletes who run slowly sweat less and.
drink hypotonic fluids before during and after the. race CF gene carriers football and tennis players, who over hydrate to prevent cramps or get. hypotonic IV hydration, Exercise Associated Hyponatremia. Beware of diagnosing the endurance athlete, with dehydration and encouraging hypotonic. fluid replacement, Symptoms occur with rapid decline in levels. below 130 mmol L, Symptoms increase with rapidity of decline.
the longer it remains low and the lower it, Exercise Associated Hyponatremia. Symptoms at levels of 125 mmol L or less, Headache vomiting swollen hands and feet. restlessness fatigue confusion and, disorientation cerebral edema wheezing. pulmonary edema, Progression of symptoms with levels below 120. cerebral edema with seizure coma brainstem, herniation respiratory arrest and death.
