Performance and acute recovery in endurance runners Rendimiento y recuperación aguda en corredores de resistencia
Bibliographic record
Abstract
Sixteen well-trained endurance runners were evaluated in two different days with the Université de Montréal Track Test (UMTT), and the time limit at maximum aerobic speed test (Tlim). Heart rate and lactate drops were examined during the acute recovery (by walking). Maximum heart rate was higher in UMTT compared with Tlim (p = 0,001). Heart rate recovery in the first minute after both protocols correlated with maximal aerobic speed (r = 0,611 and r = 0,615, p = 0,012, for UMTT and Tlim, respectively); with a correlation detected between HR recovery drops after both protocols (r = 0,824; p = 0,000). The difference between lactate levels at first and 10th min of recovery, was significantly different only in UMTT condition (p = 0,013). In summary: 1) it was found a moderate relationship between maximum aerobic speed and heart rate recovery in distance runners; 2) maximum heart rate is higher in an incremental test compared with a rectangular test in the field; 3) the significant lactate drop at 10 min of recovery only after UMTT, suggest the running protocol dependence of this parameter. Key Words:heart rate, lactate, recovery, maximum aerobic speed Dieciséis corredores de fondo bien entrenados fueron evaluados en dos días diferentes mediante la prueba de carrera en pista de la Universidad de Montreal (UMTT) y el tiempo límite a la velocidad aeróbica máxima (Tlim). Se examinó la respuesta de la frecuencia cardiaca y la lactatemia en la recuperación aguda (andando). La frecuencia cardiaca máxima fue diferente entre los dos días de valoración (p = 0,001), resultando superior en el UMTT respecto del Tlim. La recuperación de la frecuencia cardiaca en el primer minuto (RFC1) correlacionó con la velocidad aeróbica máxima (r = 0,611 y r = 0,615, p = 0,012; en el UMTT y el Tlim, respectivamente), correlacionando además los dos valores de RFC1 entre sí (r = 0,824; p = 0,000). La diferencia en la lactatemia entre la finalización y el minuto diez de la recuperación fue estadísticamente significativa sólo después del UMTT (p = 0,013). Se concluye que: 1) fue hallada una relación moderada entre la recuperación cardiaca y la velocidad aeróbica máxima en corredores de resistencia; 2) la frecuencia cardiaca máxima obtenida en una prueba incremental en el campo es superior a la alcanzada en una prueba de tipo rectangular; 3) el descenso significativo de la lactatemia a los 10 min sólo se observó después del UMTT, lo que sugiere una influencia del protocolo de carrera en este parámetro. Palabras Clave: frecuencia cardiaca, lactato, recuperación, velocidad aeróbica máxima

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.
