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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
