Which of the following is a component of high-intensity interval training (HIIT)?

High-intensity interval training (HIIT) is characterized by short, intense bursts of physical activity followed by periods of rest or lower-intensity exercise. This structure is designed to maximize cardiovascular fitness and improve metabolic efficiency in a shorter amount of time compared to traditional steady-state training. The alternating high-intensity work and recovery periods allow the body to exert its maximum capacity, leading to improved performance and endurance over time.

In contrast, low-impact exercises typically focus on minimizing stress on the joints and are not inherently associated with the interval training methodology. Consistent pacing is more characteristic of steady-state cardio rather than the variable intensity that defines HIIT. Endurance-focused steady-state cardio involves maintaining a constant level of effort over an extended period, which does not align with the principles of HIIT that emphasize intensity and variability. Thus, the choice that accurately reflects a core component of HIIT is the approach that involves short bursts of maximum effort followed by rest.
