ABSTRACT
We examined practically healthy young men (81 in the ages from 17 to 21 years), the students living in the city of Krasnoyarsk, for whom we defined their somatotypes according to V.P. Chtetzov scheme (1978) and component content of the body (fat, muscle and bone) by caliperometry technique. Catecholamine content (CC) in blood lymphocytes was analysed by luminescence-histochemical technique. Medical examination was carried out both in the fasted state, and in an hour after food intake (mixed breakfast). On an empty stomach CC content was practically the same in the young men of all the compared somatotypes. After food intake, CC statistically meaningful increase was revealed only in abdominal somatotype youngsters as compared to the same indices on an empty stomach (p=0.026). In abdominal somatotype we also found considerably higher CC content after food intake in comparison with the other somatotypes: chest (Ñ=0.021), muscle (Ñ=0.022) and inexplicit (Ñ=0.029). Also, in abdominal somatotype, we revealed the highest absolute indices of fatty tissue content in body composition as compared to other somatotypes: chest (Ñ=0.00000002), muscle (Ñ=0.0002), inexplicit (Ñ=0.000007). Considering CC level before and after food intake, we didn't mark any statistically relevant difference between the youngsters with different body mass indices (BMI). This finding could be caused by the following peculiarity of the BMI evaluation: on the one hand, the growth/weight ratio was calculated, on the other hand, body fatty tissue pronouncement wasn't. Besides, it is fatty tissue, which makes one of the most massive target tissues for CC, and therefore it greatly influences and regulates adipocyte functions. The research allows making the conclusion on the role of the expressiveness of body fatty tissue content as considerable factor, which influences CC content after food loads.
