Drink composition, voluntary drinking, and fluid balance in exercising, trained, heat-acclimatized boys.
This study examined the effects of beverage composition on the voluntary drinking pattern, body fluid balance, and thermoregulation of heat-acclimatized trained boys exercising intermittently in outdoor conditions (wet bulb globe temperature 30.4 +/- 1.0 degreesC). Twelve boys (age 13.4 +/- 0.4 yr) performed two 3-h sessions, each consisting of four 20-min cycling bouts at 60% maximal aerobic p...
متن کاملBone responses to body weight and moderate treadmill exercising in growing male obese (fa/fa) and lean Zucker rats.
OBJECTIVE To evaluate if exercise in a young growing model of obesity would be able to reduce adiposity without adversely affecting bone. METHODS Obese (fa/fa) and lean (Fa/Fa) male Zucker rats were randomly assigned (n=8-9 rats/group) to no exercise or to a moderate treadmill exercise regimen consisting of a speed of 20 m/min for approximately 1 h, 5 d/wk for 9 wks. Bone morphometry, total b...
متن کاملHeat loss and energy retention during growth in congenitally obese and lean rats.
I. Heat losses associated with the utilization of metabolizable energy for synthesis of protein and of fat during growth mere studied in Zuekcr rats selected for normal leanncss or congenital obesity. z. Measurements of energy and nitrogen balance were made on groups of four lean and four fat rats offered food ad lib. and kept at zzo. Balance trials were also conducted on groups of fat or lean ...
متن کاملEnvironmental heat stress does not reduce blood ionized calcium concentration in hens acclimated to elevated temperatures.
Changes in blood concentrations of ionized calcium and total calcium were measured in broiler breeder hens (42 wk old) relative to egg cycle and environmental temperatures. Two environmental temperature treatments were used: 1) temperature cycled daily from a low of 10 C at 0300 h to a high of 25 C at 1600 h; and 2) temperature cycled from a low of 21 C at 0300 h to a high of to a high of 39 C ...
