Effect of a Sugar-Free Branched Chain Amino Acid-Containing Sports Drink on Acute High Intensity Anaerobic Performance
Bibliographic record
Abstract
Purpose: BioSteel® high performance sports drink (HPSD) is an enticing alternative to carbohydrate-containing sports drinks that are often associated with side effects such as gastrointestinal discomfort or post-consumption hypoglycemia. BioSteel® HPSD is carbohydrate-free and provides bioavailability of branched-chain amino acids (BCAAs) and other necessary cofactors that aid in BCAAs digestion. Here, we investigated the efficacy of BioSteel® HPSD to improve high-intensity anaerobic exercise performance in young adults. Methods: A modified Wingate anaerobic test (mWAnT) was performed by fourteen healthy college students. Each subject underwent a total of nine trials, with each trial consisting of four bouts of cycling for 10 seconds / bout. The crossover design had each subject consume either BioSteel® HPSD, placebo, or water 30 minutes prior to the onset of exercise for three trials each, respectively. Results: Participants consuming BioSteel® HPSD had significantly improved average power output expressed as an average of all bouts and all trials. Analyzing exercise performance as a function of separate 10 second bouts revealed significantly higher power output (bouts 1 and 4) and peak power (bout 1) in the BioSteel® HPSD consuming group. Despite this increased power output, subjects consuming BioSteel® HPSD did not fatigue faster or to a greater extent, as evidenced by fatigue index. Translation of power output to distance travelled indicated a significantly increased distance traveled by the subjects who drank BioSteel® HPSD. Conclusion: Collectively, our data demonstrate that BioSteel® HPSD has a positive effect on acute anaerobic performance.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
