In otherwise healthy men with at least three months of training, supplementation of betaine (2.5g daily in two divided doses of 1.25g) for two weeks given a weight training program (mixture of power based exercise and standard weight training) noted that power output was increased on the bench press when assessing isometric and peak power output whereas the squat only saw benefit with isometric; repetitions to fatigue at 85% 1RM failed to see improvement.

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.
