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.

Betaine Supplementation Enhances Anabolic Endocrine And Akt Signaling In Response To Acute Bouts Of Exercise

この研究の注釈:

Supplementation of betaine at 1.25g twice daily for one week appears to, when exercising in a fasted state, increase IGF-1 (7.8%) and reduce cortisol concentrations (6.1%) and nonsignificantly increase growth hormone (6.1%) relative to placebo.

This study noted that the decrease in Akt/P70S6K signalling (anabolic signalling) during exercise was attenuated with betaine, but AMPK was not affected.

The Effects Of Chronic Betaine Supplementation On Exercise Performance, Skeletal Muscle Oxygen Saturation And Associated Biochemical Parameters In Resistance Trained Men

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.
