The purpose of this study was to determine the effect of ingesting water or carbohydrates solutions on physiologic function and performance during 1.6 h of intermittent cycling exercise in the heat (dry bulb temperature = 33 degrees C). Thirteen male subjects (24 to 35 yr) completed four separate rides. Each ride consisted of intermittent steady-state(More)
The purpose of this study was to determine the effect of ingesting fluids of varying carbohydrate content upon sensory response, physiologic function, and exercise performance during 1.25 h of intermittent cycling in a warm environment (T db=33.4°C). Twelve subjects (7 male, 5 female) completed four separate exercise sessions; each session consisted of(More)
The purpose of this study was to determine the effects of repeated ingestion of drinks containing varying concentrations of carbohydrate on gastric emptying rate during steady-state exercise. On five separate occasions, 14 subjects cycled for 90 min at an average power output of 151 +/- 2 W. At 15-min intervals, subjects ingested 227 +/- 3 ml of either(More)
The purpose of this study was to compare the physiological, sensory, and exercise performance responses to ingestion of 6% glucose, 6% fructose, and 6% sucrose solutions during cycling exercise. Twelve subjects completed three sessions consisting of 115 min of intermittent cycle ergometer exercise at 65-80% of VO2max followed by a timed performance bout(More)
The purpose of this study was to assess how selected physiological and performance responses are affected when the normal increase in plasma free fatty acid concentration during exercise is blunted by ingesting nicotinic acid. On four occasions, 10 subjects cycled at 68 +/- 1% VO2peak for 120 min followed by a timed 3.5-mile performance task. Every 15 min(More)
To study selected cardiovascular, thermoregulatory, and hormonal responses to the consumption of glycerol solutions during exercise, nine subjects cycled for 90 min at 50% peak O2 uptake in a 30 degree C, 45% relative humidity environment. Beverages tested included a 10% glycerol solution (G), a 6% carbohydrate-electrolyte beverage (CE), the 6%(More)
The purpose of this study was to determine how the ingestion of carbohydrate at varying rates influences physiological, sensory, and performance responses to prolonged exercise at 65-75% VO2max. Ten subjects ingested either a water placebo (WP) or carbohydrate solutions formulated to provide glucose at the rates of 26, 52, and 78 g, h-1 during 2 h of(More)
This study assessed the gastric emptying rates of water and four isocaloric carbohydrate solutions in resting subjects. On five occasions, subjects ingested 400 ml of water or 6% solutions of glucose, sucrose, maltodextrin, and sucrose+glucose. The double-sampling technique was used to sample stomach contents immediately after ingestion and at 10-min(More)
The antioxidants, alpha-tocopherol acetate and a quinolone derivative (Santoquin), inhibited the development of amyloidosis when added to the diet of casein-injected C3HeB/FeJ male mice. Santoquin, and to a lesser extent butylated hydroxytoluene (BHT), also depressed the appearance of a plasma protein fraction in these mice; the effect of alpha-tocopherol(More)
Abdominal cramping, nausea, diarrhea, and GI bleeding are often reported in long-distance runners. This study set out to determine the effects of prolonged (2-4 hrs) exercise and NSAID ingestion on gastric and intestinal permeability during the first 5 hrs following the 1996 Chicago Marathon. Thirty-four healthy volunteers (20 M, 14 F; ages 30-50) completed(More)
