Mass of body segment

To study bases of mechanics, we recommend you to choose one of the following web sites.
If you need to explain some mechanical variable, you can use this dictionary.

The masses of body segments can be count if you know the total height ant weight of a person. One of frequently used methods was described by Zatsiorskji and Selujanov (1979), who determined the parameters B0, B1 a B2 for each body segment.

The equation for body mass is following

,
where m (kg) is total mass of a person  and  v (in cm!) is height of a person..

The parameters B0 , B1 a B2 see table.

Centre of gravity (c.g.) of body segments (Obr. B-Ot-2-2) was determined experimentally.

Hand (manus) 39:61 %, forearm 43:57 %, upperarm 44:56 %, head+neck 50:50 %, trunk 42:58% (from shoulder), thigh 43:57%, shank 41:59 %, foot 40:60 % of total lenght of each segment ( from  proximal end).
