Final answer:
The Preparation drill in PRT combines short bursts of vigorous exercise with longer periods of moderate activity, preparing the body for subsequent activities.
Step-by-step explanation:
The Preparation drill (PD) in PRT sessions is not simply a series of vigorous exercises. Instead, it involves a pattern of physical exercise that is structured to include short periods of vigorous muscular work alternated with longer periods of medium and varied muscular work. This approach to preparation helps an individual transition into the activity phase effectively, ensuring the body is primed and ready for the exercises ahead.
Options such as a rest period, a brief meditation session, or a set of stretching exercises might also be part of a comprehensive training routine, but they do not match the description of a Preparation drill that focuses on progressive physical readiness.
