Which physical fitness component involves running during the Physical Fitness Assessment?

The 1.5-mile run is a key component of the Physical Fitness Assessment in Navy Boot Camp because it evaluates cardiovascular endurance, a critical aspect of overall fitness. This run assesses how efficiently the body can deliver oxygen to muscles during sustained physical activity, which is essential for maintaining performance during military operations. Completing the 1.5-mile run at a suitable pace indicates a level of fitness that is expected from recruits, ensuring that they are prepared for the physical demands of Navy service.

The other options, while they might involve running or walking, do not specifically align with the established assessment protocol for evaluating the endurance component in the Navy's physical fitness framework.
