Pugilistic attitude seen in fire deaths is due to:
- A Heat coagulation and shrinkage of muscles with larger flexor mass predominating ✓
- B Voluntary defensive posture assumed in agony before death
- C Spastic muscular contractions from burns to peripheral motor nerves
- D Post-mortem heat rigor, distinct in mechanism from cadaveric rigor
Explanation
Pugilistic (boxer's) attitude in fire deaths is a post-mortem phenomenon caused by heat denaturation and coagulation of muscle protein (similar to cooking) with progressive shortening. The large muscle masses of the flexor groups (biceps, hip flexors, knee flexors) are greater in bulk than the extensors, so when all muscles contract equally by percentage, net posture is flexion at all joints — resembling a boxer's stance. This is NOT voluntary, NOT rigor mortis, and NOT heat-specific rigor. Its presence does NOT indicate the deceased was alive during the fire.
