Lipid oxidation fuels recovery from exhaustive exercise in white muscle of rainbow trout
Bibliographic record
Abstract
The oxidative utilization of lipid and carbohydrate was examined in white muscle of rainbow trout (Oncorhynchus mykiss) at rest, immediately after exhaustive exercise, and for 32-h recovery. In addition to creatine phosphate and glycolysis fueling exhaustive exercise, near maximal activation of pyruvate dehydrogenase (PDH) at the end of exercise points to oxidative phosphorylation of carbohydrate as an additional source of ATP during exercise. Within 15 min postexercise, PDH activation returned to resting values, thus sparing accumulated lactate from oxidation. Glycogen synthase activity matched the rate of glycogen resynthesis and represented near maximal activation. Decreases in white muscle free carnitine, increases in long-chain fatty acyl carnitine, and sustained elevations of acetyl-CoA and acetyl carnitine indicate a rapid utilization of lipid to supply ATP for recovery. Increases in malonyl-CoA during recovery suggest that malonyl-CoA may not regulate carnitine palmitoyltransferase-1 in trout muscle during recovery, but instead it may act to elongate short-chain fatty acids for mitochondrial oxidation. In addition, decreases in intramuscular triacylglycerol and in plasma nonesterified fatty acids indicate that both endogenous and exogenous lipid fuels may be oxidized during recovery.

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.
