A relatively new nutritional supplement
intended to enhance athletic performance
may do just the opposite. University of
British Columbia Okanagan researchers
looked at relatively untested ketone salts
ability to improve short duration and high
intensity workouts, such as running a tenkilometer
race or cycling up a hill. They
discovered that ketone salt supplements
actually impair high-intensity exercise
performance. Co-author professor
Jonathan Little says volunteers who
consumed ketone nutritional supplements
prior to a cycling time trial did seven
percent worse than on the day when the
same volunteers consumed a placebo.
The study was published in Applied
Physiology, Nutrition and Metabolism.
