Modern devices of pulse measurement methods are based on different physiological phenomena of nature – changes biopotential heart blood flow volume modulation of arteries and capillaries, mechanical vibrations of their walls, acoustic phenomen bioradiolocation. The most popular methods are based on electrocardiography and plethysmography.
Features of phase changes of some morphofunctional indices in girls during ovarian-menstrual cycle
(2019) Budzyn, Vira; Matviyas, Olha; Lapychak, Ihor; Bazylyak, Natalia; Zharska, Natalia
The problem of dynamics of changes in the main morphological and functional indices during the ovarian - menstrual cycle in girls aged 18-20, who deal with football, and “non-sporting” girls of the same age, was studied. Cyclic hormonal changes in the female body, affecting the functional state of the motor apparatus, may be accompanied by changes in certain morphological parameters of female athletes. The data obtained allowed to establish the presence of certain cyclic changes in the main morphological and functional indicators and their calculation indices. The largest digital values of height, mass, and body surface of the girls in both groups were established in the I and II phases of the biological cycle due to the delayed water in the body in the specified phases because of hormonal changes. To a certain extent, this conclusion is confirmed by the highest values of the Kettle's weight index in certain (I and V) phases. At the same time, in the middle of the cycle (phase III), there is a tendency to decrease the mass and body surface.
