Effect of exercise on FA profiles in n−3 FA‐supplemented and‐nonsupplemented premenopausal women
Bibliographic record
Abstract
The purpose of this double-blind study was to investigate the influence of exercise on the FA profile of the non-esterified FA (NEFA) and phospholipid fractions in plasma of sedentary women supplemented with n-3 FA vs. women supplemented with oil containing no n-3 FA. Twenty sedentary, premenopausal women were randomly assigned to receive 12 capsules daily of either fish oil (3.5 g EPA and 2.4 g DHA per day, each as the ethyl ester) or evening primrose oil capsules (no detectable EPA or DHA). Each subject consumed the capsules for one menstrual cycle. At the end of the supplementation period, the sedentary subjects underwent an acute exercise trial [55% maximal oxygen consumption (VO2 max), 45 min] on a cycle ergometer. Two subjects in the fish oil group were removed from all calculations owing to noncompliance for reasons not related to side effects. There were no changes in the phospholipid composition of either group of women after exercise. In both control and fish oil-supplemented women, NEFA levels in general rose after exercise. There were no changes in the percentage of any given individual NEFA in either supplementation group. However, absolute levels of certain individual NEFA (16:0, 18:0, 18:1, and 18:3n-3) increased with exercise. Women supplemented with fish oil had increased levels of n-3 NEFA IEPA, DHA, and docosapentaenoic acid (DPA)] prior to exercise. Exercise did not, however, increase the absolute levels of n-3 NEFA in the blood.

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.
