Mean overall compression score (1 SD Error Bar) by interval, pretest/training/posttest assessment, and session.
Horizontal dashed line at 75 represents the minimum performance target.
Table 1.
Pretest means (SD) for compression measures across sessions and intervals.
Contrasts provide post hoc comparisons of session 1 and 4 for each interval, with t-values and significance levels at * p < .05, ** p < .01, and *** p < .001.

Mean percentages of compressions with adequate depth, rate, release, and hand placement by interval, session, and pretest/training/posttest assessment.
