Objectives
Narrative objectives1
To investigate temporal changes in chest compression quality during 2 minutes of continuous chest compressions performed at a controlled rate of 120 compressions per minute while kneeling on a bed, and to examine the muscle activity and joint angle characteristics associated with these changes.

Assessment
Primary outcomes
Proportion of chest compressions achieving the target depth in each of four 60-compression blocks during 2 minutes of continuous chest compressions performed at 120 compressions per minute. The four blocks comprise compressions 1-60, 61-120, 121-180, and 181-240. The target depth is defined as 5 to 6 cm, and the proportion is calculated by dividing the number of compressions within the target depth by the total number of compressions in each block.

Interventions/Control_1
Participants perform chest compressions on a training manikin placed on a backboard on a horizontal bed with the brakes locked. Chest compressions are performed while kneeling on the bed at a rate of 120 compressions per minute controlled by a metronome. Each participant completes one 30-second practice session, rests for at least 5 minutes, and then performs one 2-minute continuous chest compression session. Rescue breaths are not performed. Each participant takes part in the intervention once on a single day.
