Influence Of Betaine Consumption On Strenuous Running And Sprinting In A Hot Environment

Effect None
Trial Design Double blind
Trial Length 1-7 Days
Number of Subjects 10
Sex Male
Age Range 18-29
Body Types Trained, Average
Notes for this study:
In 10 otherwise healthy male runners given betaine (5g per liter of solution) as a rehydration formula after mild exercise-induced dehydration, betaine failed to subsequently increased physical performance on a treadmill test relative to the control (regardless of whether betaine was paired with water or carbohydrate/electrolyte solution) although there may have been a minor increase in oxygen consumption in the final sprint of the betaine plus carbohydrate group (VO2 max was still unaffected). Thirst was also unaffected as well as plasma electrolytes.
