Center of mass of human's body segments

In biomechanics, determination of the body’s center of mass has always been an important part of many biomechanical studies. However, it is always a challenge to find it and often obtained results are only estimations, guesses. Indeed, to find someone’s body center of mass isn’t as easy as finding center of mass of simple rigid objects with uniform density, where it usually could be found at the centroid. The human body is different according to the gender, the age, the ethnicity, the physical shape, body fat distribution, etc. As it is composed of bones and muscles, results may differ drastically depending on which muscles are tense or on the body positioning. Nowadays, as a new era of biomechanics is approaching with a superior kind of prosthesis or exoskeletons that calls upon an “augmented humanity”, or even with gait modelling. It is important to find an experimental method that gives precise positioning of such an important data as the center of gravity of body segments, widely available to scientists that would need to go further in their researches, without having to use sophisticated equipment or time-consuming methods.

Comparison of two approaches for calculation of the geometric and inertial characteristics of the human body of the Bulgarian population

On the basis of a representative anthropological investigation of 5290 individuals (2435 males and 2855 females) of the Bulgarian population at the age of 30–40 years (YORDANOV et al. [1]) we proposed a 3D biomechanical model of human body of the average Bulgarian male and female and compared two different possible approaches to calculate analytically and to evaluate numerically the corresponding geometric and inertial characteristics of all the segments of the body. In the framework of the first approach, we calculated the positions of the centres of mass of the segments of human body as well as their inertial characteristics merely by using the initial original anthropometrical data, while in the second approach we adjusted the data by using the method based on regression equations. Wherever possible, we presented a comparison of our data with those available in the literature on other Caucasians and determined in which cases the use of which approach is more reliable.
