Model for the physics of motion

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of constructing a scientific model to analyze the interactions of motion in the human body, particularly in the context of sports and martial arts. It explores the potential for modeling optimal force transmission during movement and the effects of specific exercises on long-term health.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that it may be possible to create a model for human motion using simplified representations of muscles, ligaments, and cartilage, comparing it to weather modeling.
  • Another participant argues that the complexity of the human body, with its numerous joints, levers, and muscular patterns, makes such modeling very complicated and potentially chaotic.
  • A different participant points out that this type of modeling falls under biomechanics and human motion, recommending resources and courses that cover these principles.
  • Another participant mentions that concepts related to this modeling are also addressed within exercise physiology.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and complexity of modeling human motion, with some acknowledging the potential for such models while others emphasize the challenges and complications involved. No consensus is reached regarding the practicality of the proposed modeling approach.

Contextual Notes

The discussion highlights limitations related to the unknown variables in human motion and the dependence on a comprehensive understanding of both mechanical and biological principles. Specific assumptions about the effects of certain movements on health remain unresolved.

Using simplified models for the muscles, ligaments, and cartileges, do you think that it's feasible to construct a scientific model for all of the interactions of motion that occur in the human body in order to calculate optimal transmission of force whilst moving, striking, and evading?

Given the relatively primitive state of sport science even for top level athletes, I assume that this is akin to building a weather model that takes into account all the variables. It seems to me that there are only a limited number of components and joint types, each with their own range of movement, so it shouldn't be THAT difficult for people who know what they're doing...

To what degree is it possible to examine and prove the deliterious effects of certain movements, such as deep knee bends, classical sit ups, and knuckle push ups upon the body?

I ask because I'm a karate instructor with a large web site, and I have a strong intuition that the way in which karateka train and move (not counting actual combat) is extremely bad for their long-term health. That being the case, I'd very much llike to develop better ways of training that
are beneficial to my students and myself.

Many thanks in advance.

Just very, very complicated.
too many joints, too many levers, too many muscles, too many muscular patterns...

You'll find a pseudo-chaotic system where too many variables are unkown.
 
This kind of modelling is covered by those with a grasp of both mechanical principles and biology (anatomy). Search under biomechanics and human motion Here is an example

There are courses taught specifically on Biomechanics. Here is one text I found. (this reference "examines techniques used to measure and analyze all body movements as mechanical systems, including such everyday movements as walking.")
 
Some of those concepts would be covered within the discipline of exercise physiology as well.
