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.

Effect Of Betaine Supplementation On Power Performance And Fatigue

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.

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

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.
