GASTRIC EMPTYING DURING WALKING AND RUNNING: EFFECTS OF VARIED EXERCISE INTENSITY

Gastric emptying is increased during running (50%-70% maximal aerobic uptake, VO2max) as compared to rest. Whether this increase varies as a function of mode (i.e. walking vs running) and intensity of treadmill exercise is unknown. To examine the gastric emptying characteristics of water during treadmill exercise performed over a wide range of intensities relative to [...]

NATIONAL ATHLETIC TRAINERSA’ ASSOCIATION POSITION STATEMENT: FLUID REPLACEMENT FOR ATHLETES

OBJECTIVE: To present recommendations to optimize the fluid-replacement practices of athletes. BACKGROUND: Dehydration can compromise athletic performance and increase the risk of exertional heat injury. Athletes do not voluntarily drink sufficient water to prevent dehydration during physical activity. Drinking behavior can be modified by education, increasing accessibility, and optimizing palatability. However, excessive overdrinking should be [...]
