Acute L-arginine Alpha Ketoglutarate Supplementation Fails To Improve Muscular Performance In Resistance Trained And Untrained Men

Effect None
Trial Design Double blind
Trial Length 24 hours
Number of Subjects 16
Gender Male
Age Range 18-29
Body Types Trained, Untrained, Average
Notes for this study:
3g of Arginine AAKG, when used acutely 45 minute before exercise, failed to improve performance in either naive or trained subjects.

No Effect Of Short-term Arginine Supplementation On Nitric Oxide Production, Metabolism And Performance In Intermittent Exercise In Athletes

Effect None
Trial Design Double blind
Trial Length 1-7 Days
Number of Subjects 10
Gender Male
Age Range 18-29
Body Types Trained, Average
Notes for this study:
Peak and mean power output as well as biomarkers of nitric oxide metabolism (nitrate and nitrite, citrulline) were unaffected in judo athletes given 3 days of 6g L-arginine supplementation prior to a cycle ergometer test. Despite no increase in plasma citrulline, however, an increase in plasma arginine was noted.
