The paper analyses the variability through age of some body proportions in metric and modular system, compared with conventional canons or from the art history. The subject's group include 753 males and 669 females between 18 to 65 years old from the main historical and geographical provinces of Romania. The variation of stature average values and of the 5 dimensions-modules (head length, total face length, sternum length, thorax depth, hand length) spread through 5 decades of age was assessed. The average values of the proportions of these modules for stature, among them some dimensions of the torso, have been calculated. The average values of the obtained 24 proportions have been compared by decades of age with the average values from the group and with the above mentioned canons. The harmony of the proportions has been verified by significance test (Student test, Z-score, etc.). The results show a harmonious development of the body proportions, especially in the first decades of age for both sexes. [ABSTRACT FROM AUTHOR]

This paper is the third study regarding the harmony of some body proportions appreciated in metric and modular system (Luca et al., 2018: 69--83; Luca et al., 2019: 39--53). The group of subjects comprises 743 males with an average age of 36.88 ± 11.88 years and 709 females with an average age of 32.74 ± 10.62 years, coming from the main historical and geographical provinces of Romania. Five dimension modules (head length, total facial height, sternum height, chest depth, hand length) were put in proportion with stature/height, between them and with three torso diameters (shoulders width, pelvis width, transverse thoracic diameter) resulting 25 proportions on which are added the indexes of shoulders width, pelvis width, and torso shape. The average values of some dimensions and of torso indexes were compared with the average national values (Z). No significant differences were observed, which confers representativeness for the group. The average values of the proportions resulted based on dimensions modules were compared with canons from the art history and with "canons" deduced by us from the anthropometric practice based on new dimension modules (sternum height, chest depth, head length). The results mostly confirm the closeness to the canons and sustain the harmonious development of the torso despite the volume fluctuations, the differences between the samples, and the possible microevolutive differences. The metric and conformative dimorphism highlighted by Student test (t), sexual dimorphism index, and Z-test illustrate a harmonious development for both sexes, a little more emphasized for males.
