Abstract

fetched live from OpenAlex

The purpose of this study was to determine if pre-exercise glucose ingestion (at 5 min and 35 min) would improve 4000m swimming performance. Ten male triathletes (Mean ± SD: age 29.5 ± 5.0 yrs, VO2max 3.74 ± 0.10 L.min−1) swam 4000m on three occasions following the consumption of either; 1. A 10% glucose solution 5-min prior to exercise (G5), 2. A 10% glucose solution 35-min prior to exercise (G35), 3. A similar volume of placebo (PL). Dietary intake and exercise were regulated for 48 hours prior to each trial. Despite a significant difference (p < 0.01) in blood glucose concentration prior to exercise (Mean ± SD in mmol.L−1: G35 8.4 ± 1.1, G5 5.2 ± 0.5, PL 5.3 ± 0.4), no significant differences were observed in total time (Mean ± SD in minutes: G35 70.7 ± 7.6, G5 70.1 ± 7.6, PL 71.9 ± 8.4), post-exercise blood glucose (Mean ± SD in mmol.L−1: G35 5.1 ± 1.1, G5 5.1 ± 0.9, PL 5.3 ± 0.4), and average heart rate (Mean ± SD in bpm: G35 155.8 ± 10.8, G5 153.6 ± 12.6, PL 152.0 ± 12.5) (p > 0.05). The results of this study indicate that despite a greater reliance on carbohydrate with this mode of exercise, there was no significant improvement in performance following glucose ingestion. The data further indicates that no decrements to performance were observed following the ingestion of a high glycemic solution thirty-five minutes prior to exercise, despite significant differences in blood glucose between trials immediately prior to exercise.

Not 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.
