Physics of the Human Body in Earths Gravitational Field :: physics human gravity

No Conclusion The force of gravity affects all "bodies" in the universe. How well each human falls into the imaginary line of gravity determines the energy they must have to expel to live within this force. The ideal axis for obtaining the greatest balance is one that is a strait line through the center mass of the body. This line should be identical to the one between the gravitational force between the body and the earth. The human body has adapted over many generations and there are markers that will show where a strait line should form to be properly aligned. This imaginary line connects points at the top of the head, middle of the ear, middle of the shoulder, midpoint of the hip joint, center of the knee joint, and center of the ankle joint. Finding the angles that this line forms from unevenness will explain some things about the amount of energy and mobility this person spends to stay upright. If a person is not consciously holding their muscles to stay up, they must have chronic tension in their muscles to even themselves out. Over time this tension has been programmed into their brain and the connective tissue has been bundled up to help hold the tension. This tension has most definitely limited mobility of the antagonist muscles because they must now use extra force to move. These tensions are most likely formed from the overall function of the individual. For example, if a person is a shot-putter they will build up connective tissue to reinforce themselves from the large amount of torque placed on their bodies outside of their Center of Mass. Over time, their body will adapt to resist the forces its put on it but outside of shot-put, those tensions will remain as part of the person. Eventually, the chronic torque t hat the tensions of the muscles put on the body will deform the lines of symmetry and be detrimental to the person. When people lift weights, it is almost impossible to isolate the lifting to a specific muscle due to the body's make up and connections in the brain. Phisiologicly, there are limitations to each muscle. When an isolated lift is attempted and one muscle can't do the job and more are called in that might not act directly on the lift but help in some way, it is called recruitment. Recruitment generally involves using more superficcial muscles than inferior ones and will result in a greater torque beacuse of this.
