PECULIARITIES OF HEART RHYTHM VARIABILITY OF STUDENTS –SPORTSMEN, HAVING DIFFERENT WILL ACTIVITY STYLES ^{[№ 12 ' 2016]}
The article is devoted to studying heart rhythm variability peculiarities of students-sportsmen, having different will activity styles within the conditions of combined studying, professional and sport activities. Professional activities success is determined by individual resources peculiarities, individual will activity styles are included into them. Will activity styles are dynamic, genetically determinated by psychological peculiarities; they define students-sportsmen's adaptive peculiarities and health under conditions of combined loading. Generally accepted evaluation methods for will qualities were used (N.V. Stambulova's form). Heart work data record was conducted by hardware and software complex “Auinomic Nervous System-Micro” (Limited liability company “Neurosoft”) at rest. Such data of heart rhythm spectroscopic analysis variability were studied: total spectrum power (TP,) very low frequency (VLF), low (LF), high (HF) frequency waves power, vagosympathetic balance coefficient (LF/HF). Research results were analysed by generally accepted statistical methods. According to the spectroscopic analysis data, maximal adaptive kind of neurovegetative reaction was shown by students-sportsmen, having flexible style of will activity. Such students have shown evident parasympathicotoniс reaction, it is characteristic for them. Students-sportsmen, having restrained will activity style, usually have autonomic nervous system parts balance with humoral-metabolic influences prevalence over heart rhythm. For students-sportsmen, having motivational will activity style, evident sympathycotonic reaction is characteristic. Studying peculiarities of heart rhythm spectriscopic analysis variability, defining vegetative regulation prevalent style of students-sportsmen, having different styles of will activity allows prediction of their functional and reserve organism's abilities, training process managing and also predict their sport results.

INFLUENCE OF LONGITUDINAL MAGNETIC FIELD ON RADIAL DISTRIBUTION OF METASTABLE ATOMS OF XENON IN IMPULSING DISCHARGE OF HE-XEХMIXES ^{[№ 10 ' 2005]}
The influence is investigated of longitudinal magnetic field on radial distribution of concentration of metastable atoms in an active phase and in afterglow of the impulsing discharde of He -Xe mixes. It is shown, that in the magnetic field the radial course of metastable atoms concentration essentially varies, coming nearer to bessel functions. It is explained by reduction of radial cataphoresis degree. Presence of molecular ions of xenon is established also.
