この研究の注釈:

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.

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.
