Abstract
The hypothesis that the distribution of weekly training across several short sessions, as opposed to fewer longer sessions, enhances maximal strength gain without compromising maximal oxygen uptake was evaluated. Twenty-nine subjects completed an 8-week controlled parallel-group training intervention. One group ("micro training" [MI]: n = 21) performed nine 15-minute training sessions weekly, whereas a second group ("classical training" [CL]: n = 8) completed exactly the same training on a weekly basis but as three 45-minute sessions. For each group, each session comprised exclusively strength, high-intensity cardiovascular training or muscle endurance training. Both groups increased shuttle run performance (MI: 1,373 ± 133 m vs. 1,498 ± 126 m, p = 0.05; CL: 1,074 ± 213 m vs. 1,451 ± 202 m, p

Abstract
This article contains results of the comparative study of the functional state of respiratory and cardiovascular systems of almost healthy students (man) of age 19-22, inhabitants of mountain and plain regions of Latin America during their adaptation to the conditions of middle Russia. We have established that there are reliable distinctions in the functional state of cardio-respiratory system of students from mountain and plain regions of Latin America. So for representatives of mountain regions of LA were typical higher indicators of vital capacity, permeability of large and medium bronchial tubes, stroke volume, lower indicators of heart rate, systolic arterial pressure, myocard tension index, but higher coefficient of myocard efficiency than for inhabitants the plain. Considerable distinctions have been observed also in the intercommunication between different indicators. There have been marked considerable correlation connections between small bronchial tubes permeability and cardiovascular system indicators for plain inhabitants. For mountain regions inhabitants almost every indicator of bronchial tubes permeability correlate reliably with vital capacity, but didn't correlate with hemodynamics indicators.

Abstract
The paper presents the results of studying the health status of Kemerovo schoolchildren from the parameters of their physical health and adaptation potential. Characteristic changes in these parameters have been ascertained in different age- and gender-specific groups. Overall, there are progressive decreases in their physical health and functional capacities with age.

Abstract
INTRODUCTION: Cold habituation could affect sympatho-vagal balance, which modulates cold stress responses. The study examined cardiovascular autonomic function at the sinus node level during controlled breathing and while undertaking isometric exercise during whole-body cold exposure before and after cold acclimation. METHODS: There were 10 male subjects who were exposed to control (25 degrees C) and cold (10 degrees C) environments for 2 h on 10 successive days in a laboratory. Time and frequency domain heart rate variability (HRV) in terms of root mean square of successive differences in RR intervals, total, high, and low frequency power were determined from controlled breathing at the beginning and end of cold acclimation. Heart rate and blood pressure during an isometric handgrip test (30% MVC for 3 min) were recorded at the beginning and end of cold acclimation. Catecholamines (NE and E), mean skin (Tsk), and rectal temperatures (Trect) were measured. RESULTS: Acute cold exposure increased total (36%), low (16%), and high frequency power (25%) and RMSSD (34%). Cold acclimation resulted in higher Tsk (0.6 degrees C) and lower NE (24%) response in cold. The cold-induced elevation in high frequency power became significant after cold acclimation, while other HRV parameters remained unchanged. A smaller increase in heart rate and blood pressure occurred at 10 degrees C during the handgrip test after cold acclimation. DISCUSSION: Cold exposure increased sympathetic activity, which was blunted after cold acclimation. Parasympathetic activity showed a minor increase in cold, which was enhanced after cold acclimation. In conclusion, cold habituation lowers sympathetic activation and causes a shift toward increased parasympathetic activity.

Abstract
The membrane properties of short type blowfly photoreceptors (R1-6) were investigated in dark and light adaptation with single electrode current and voltage clamp techniques. The impedance of the cells was defined in frequency domain by using discontinuous current clamp and white-noise-modulated current injection. We found that the slow activation and relaxation of the voltage-dependent K+ conductance transform the photoreceptor membrane effectively into a band-pass filter. This behaviour could be observed under current clamp as voltage-dependent outward and inward rectification of the membrane. The voltage-dependent band-pass filtering is likely to be present in all neurons with graded potentials and voltage-dependent membrane conductances.

Abstract
In 98 athletes of cyclic kinds of sport the biochemical parameters of blood after long physical loadings were studied. The level of ATP, glucose, LDG, creatinine, general calcium and ionized calcium of blood plasma, POL indices and antioxidant system (AOS) were accessed. During adaptation to significant physical loadings, LDG and ATP level were reduced; the parameters of POL and creatinine were raised; AOS, general calcium and ionized calcium were insignificantly reduced. These shifts were less expressed in athletes with good adaptation and it is possible to use these parameters as a criterion of a degree of adaptation in high class athletes.

Abstract
The present study was devoted to the investigation of biological adaptation of children aged 6-7 years with retardation of mental development (RMD) in pre-school correctional educational institutions. Under supervision there were 69 children, out of them 34 RMD cases and 35 children in whom mental development corresponds to age-control group--35 persons. The increase in sympatico-adrenergic effects and centralized heart rhythm control was revealed in children of both groups under comparison, but in RMD cases these effects were more pronounced. Adaptation reserves in RMD children appeared to be lower than in children in whom mental development corresponds to the age. Gender differences of adaptive reserves in children have been established
