Overview

Multicentric study finds physical fitness influences muscle activity and chest compression quality during CPR.

Key Points

  • Active participants maintained better compression depth longer during CPR compared to sedentary individuals.
  • Sedentary individuals reported fatigue earlier at 96 seconds versus 180 seconds for active participants.
  • EMG analysis indicated higher muscle fiber recruitment for sedentary participants, though not significantly different.
  • Compression depth of sedentary participants dropped to below 5 cm after 75 seconds of chest compressions.
