адаптация

Изучены психоэмоциональный статус и функциональное состояние
студентов-спортсменов при экзаменационном стрессе. Установ-
лено, что основой психоэмоционального напряжения спортсменов
является личностная тревожность. Выявлена четкая зависимость
между уровнем личностной тревожности студентов-спортсменов и
характером их реактивности на экзаменационный стресс.
 

The living state of woody plants having different levels of thermal damages in the summer of 2010 was studied. It is shown that a number of species had partial drying out and the death of trees unevenly in plantations of different age and localities. In a favourable ecological environment they remained healthy. They are mesophytes and mesohygrophytes which are on the southern border of the areas, mostly explerents. The trees and shrubs of floodplain forests and certain introducents are tolerant of a thermal stress.

This work is devoted to the comparative analysis of the functional state of systemic hemodynamics in Russian and foreign students depending on the localization of the transition zone in the chest leads of ECG during the active orthostatic test. Having assessed physical development, we measured the parameters of arterial pressure and ECG using the module «Electrocardiogram» APK «Valenta». The prevalence of asthenic type of physique in foreign students against the deficiency of physical development determines the vertical position of the heart.

The peculiarities of adaptation and variability of Salix alba L. at the morphological level were studied in extreme natural and technogenic conditions of the Southern Urals. It was found that Salix alba is characterized by a wide ecological valence, and in terms of morphological variability – is stable morphological structure. The influence of geographical, climatic and anthropogenic factors on the level of morphological integration of Salix alba was revealed.
