Oxygen consumption efficiency in firefighters: roles of fatigue and rescue task
Task load is the primary factor influencing oxygen efficiency during high-intensity shuttle sprints. Large-load tasks resulted in significantly lower standardized oxygen consumption across all fatigue states and rescue methods, indicating a "small load-low efficiency" phenomenon. Prioritizing large-load (30 kg) tasks in time-critical emergencies may improve rescue efficiency.
