Demandas físicas y fisiológicas en el Hockey hierba femenino: diferencias entre los tiempos de juego
Bibliographic record
Abstract
Coaches and physical trainers must know the physical and physiological demands of field hockey to be able to tailor trainings based on the specific competition needs. The objective of the study was to analyze the patterns of movement of field hockey players during competition throughout four match quarters. A total of 18 players (22.8 ± 2.9 years of age), were monitored with GPS and heart rate monitor. The players covered 6,668 m, 276 of which were at high intensity (>18 km·h-1); an average speed of 99.33 m·min-1 and 7.28 sprints (> 20 km·h-1) were recorded by match. Those players who played the full match decreased the distance covered in the last quarter (p <.001), substitutes not displaying that trend. The maximum heart rate reached in the last quarter was lower than in the previous ones (p <.001). We can consider hockey as an intermittent intensity sport producing fatigue, therefore coaches should manage rotational changes during match with efficiency.

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.
