BCAAs and Arginine Improve Performance in 2 Consecutive Days, wait what???

[TheFugitive]

The purpose of this study is to investigate the effect of combined supplementation of branched-chain amino acids (BCAA) and arginine on intermittent sprint performance in simulated handball games on 2 consecutive days. Methods: Fifteen male and seven female handball players consumed 0.17 g/kg BCAA and 0.04 g/kg arginine together (AA trial), or placebo (PB trial) before exercise. Each trial contained two 60-min simulated handball games on consecutive days. The game was consisted of 30 identical 2-min blocks and a 20 m all-out sprint was performed at the end of each block. The performance, measured by percentage changes of sprint time between day 1 and 2, was significantly better in the AA trial (first half: AA trial: -1.34±0.60%, PB trial: -0.21±0.69%; second half: AA trial: -1.68±0.58%, PB trial: 0.49±0.42%). The average ratings of perceive exertion throughout the 2-day trial was significantly lower in the AA trial (14.2±0.3) than the PB trial (15.1±0.4). Concurrently, post-exercise tryptophan/BCAA ratio on both days in the AA trial was significantly lower than the baseline. This study showed that BCAA and arginine supplementation could improve performance in intermittent sprints on the second consecutive day of simulated handball games in well-trained athletes by potentially alleviating central fatigue.

On the days of the trials, the subjects reported to the laboratory in the early morning after an overnight fast, then consumed the standardized breakfast. After the breakfast, the subjects in the AA trial ingested 0.17 g/kg BCAA (leucine: isoleucine: valine = 2:1:1, powdered form, Optimum Nutrition, Inc, Aurora, IL, USA) and 0.04 g/kg arginine (in capsule, General Nutrition Corporation, Pittsburgh, PA, USA). BCAA powder was dissolved in 250 ml grape juice to mask the taste. In the PB trial, the subjects ingested starch powder and capsules containing starch as the placebo. The starch power, at the same amount as the BCAA powder in the AA trial, was also dissolved in 250 ml of grape juice. The number of capsule ingested in the PB trial was the same as that in the AA trial. Our preliminary study has shown that the plasma BCAA and arginine concentrations would peak after 1 hr of ingestion (data not shown). Therefore, the supplementations were consumed 1 hr before the exercise in this study.

What did the standardized breakfast consist of ?

so if a man weighed 200lb that would be 15 grams of BCAAs?

[lucia316]

Dat BCAA and arginine making epic 1/100ths of seconds difference in sprint time and tiny differences in perceived exertion

Solved BCAAs and arginine are the new hawt!!!!!!!
