Autonomic nervous system (ANS) recovery following two types of supramaximal exercise: 1 Wingate (1W) and sprint interval exercise (SIE)
Bibliographic record
Abstract
The ANS is an important regulator of the cardiovascular system. ANS recovery following 2 types of supramaximal exercise (1W and SIE) was studied using baroreceptor sensitivity (BRS). SIE consists of 4 Wingates interspersed with 4 min. of light cycling. The RR intervals (RRi) and blood pressure (BP) of nine males, aged 18–22 yrs. were monitored during 10 min. of supine rest and 8 min. of standing after 50 min. of supine rest before exercise (PRE); after 50 min. of supine rest after exercise (PST1); and 1 h. 50 min. after exercise (PST2). Baroreceptor sensitivity (BRS:ms/mm. Hg) was determined as a ratio of 3 consecutive increases/decreases in the RRi and systolic BP. Supine BRS was significantly lower (p<0.001) at PST1 (6.771±1.120) than PRE (15.289±1.809) and PST2 (11.273±1.333). BRS at PST2 returned to PRE values after 1W, but remained lower after SIE (p=0.02). Standing BRS was significantly less (p<0.001) at PST1 (2.272±0.482) than PRE (5.599±0.770) or PST2 (3.713±0.620) and returned to PRE values after 1W, but not after SIE (p=0.01). We conclude that ANS takes longer than 1 h. to recover following supramaximal exercise, and recovery is longer after SIE than 1W. This study was supported by NSERC.

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.
