Help with force & pressure on spine while bench pressing weights

Click For Summary
SUMMARY

The discussion focuses on calculating the force exerted on the human spine during bench pressing on different surfaces. An average adult male weighing 90.72 kg and lifting 102.06 kg experiences varying pressure based on the surface type. The maximum force on a hard surface, such as wood, is significantly higher than on a soft surface like an air cushion. The biomechanical principles governing these forces are essential for understanding the impact of weightlifting on spinal health.

PREREQUISITES
  • Understanding of basic biomechanics
  • Knowledge of weightlifting techniques
  • Familiarity with force and pressure calculations
  • Awareness of different surface types and their properties
NEXT STEPS
  • Research "Biomechanics of weightlifting" for foundational concepts
  • Explore "Biomechanics of the bench press" for specific insights
  • Study force calculation methods in sports science
  • Investigate the effects of surface types on athletic performance
USEFUL FOR

Weightlifters, fitness trainers, sports scientists, and anyone interested in the biomechanics of lifting and spinal health.

Hey everyone. I've never been very good at math/science so I'm seeking a little help from this forum in hopes that there is someone out there who can provide me or guide me to an answer. What I'm trying to figure out is the difference in force or pressure exerted on the human spine for an average adult male while doing a bench press on two different surfaces. If we use a length of 78 cm for spine length. A body weight of 90.72 kg. A bench press weight of 102.06 kg. Distance the weight bar travels 46 cm (downward only). Surface area is 1600 cm. What is the maximum force on the spine on a very hard surface (little to no compression...like a wood)? What is the maximum force on the spine on a very soft surface (like an air cushion)? Any help here would be incredibly appreciated. Thank you so much.

Greg
