この研究の注釈:

Supplementation of 2.5g TMG with 500mL gatorade in resistance trained men for two weeks appears to (in a fasted condition following a final 1.25g dose) increase work volume conducted on the bench press during the workout by 6.5%, although the increase of reps during any particular set or maximal power output were not affected.

The increase in lactate production seen in placebo (270%) was attenuated with betaine (210%), but lipid peroxidation (MDA) and nitric oxide (assessed by NOx) were unaffected.

この研究の注釈:

In active college aged men given betaine supplementation at 2.5g daily for a period of two weeks, there were no improvements in power output assessed by wingate, bench throw or squat jump but when promoted to exercise to fatigue (90% of 1RM on bench or squat) but did not benefit bench press performance. There were no differences in perceived fatigue nor soreness between groups.

この研究の注釈:

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.
