What defines hollow sprints in training?

Hollow sprints are characterized by alternating between periods of high-intensity sprinting and lower-intensity recovery phases, such as walking or jogging. This method allows athletes to work on their sprinting speed while also focusing on the recovery component, promoting both aerobic and anaerobic fitness. The recovery phase is crucial, as it helps maintain quality during the sprinting intervals and allows the body to adapt to the intensity of the workout.

This structure of alternating between intense effort and active recovery is beneficial for increasing speed and overall conditioning, making it easier for athletes to manage fatigue while enhancing their performance capabilities during competitive scenarios. The other options either suggest continuous effort without recovery or introduce elements that do not align with the fundamental principle of hollow sprints.
