Abstract
International Journal of Exercise Science 14(6): 666-676, 2021. The purpose of this investigation was to design and examine the reliability of a 7×15m repeated on-ice skating sprint test for female ice hockey players. Seventeen women ( ± SD age, height and body mass = 21 ± 2 years, 166.2 ± 6.4 cm and 61.9 ± 7.7 kg, respectively) completed 7 consecutive on-ice sprints of 15m repeated every 15s. Two trials of the test were performed on the same day and then repeated on a different day approximately 1 week later for a total of 4 trials. The fastest 15m time, mean time for 7 sprints and total sprint time collapsed across all 4 trials was 2.96 ± 0.12s, 3.05 ± 0.13s and 21.35 ± 0.89s, respectively. There were no significant differences between trials for any variable. Typical error (TE), coefficient of variation (%CV) and intra-class coefficients (ICC) for the fastest 15m time, mean of 7 sprints, and total time were ICC = 0.77, TE = 0.06s and %CV = 2.1; ICC = 0.91; TE = 0.04s and %CV = 1.4; and, ICC = 0.91; TE = 0.29 and %CV = 1.4 for all 4 trials, respectively. Players in the forward position had a faster mean 15m time and lower total time compared to those in the defensive position (p < 0.05). These findings show that a 7×15m repeated on-ice sprint test for varsity women ice hockey players was reliable. It was also found that forwards had a better mean of 7 sprint time and faster total time compared to players in the defensive position.

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 it
