Effect of single physical load of different duration and intensity on cognitive function.

Unlabelled: The aim of this study was to determine the effect of a single physical load of different duration and intensity on cognitive function.

Material And Methods: The study population comprised 90 male soldiers. The subjects were randomly divided into two groups: experimental (n=60) and control group (n=30).

[Influence of heating and cooling on muscle fatigue and recovery].

The aim of the present study was to establish the influence of muscle heating and cooling on knee flexors and extensors during fatiguing exercise. The participants of the study were 10 healthy males aged 19-23 years. The participants of the study were tested with the isokinetic dynamometer.

[Cooling makes recovery of muscle faster after eccentric-concentric than concentric exercise].

The aim of the study was to establish the influence of muscle cooling on muscle recovery after concentric and eccentric-concentric exercise. Healthy untrained males (n=40) took part in this study. During the first experiment, subjects performed concentric and during the second--eccentric-concentric exercise.

[The structure of myocardial nerve plexus of human auricle of the right atrium and its relation to myocardial ischemia, functional status of the heart, and age].

The aim of this study was to investigate and evaluate morphometrically the relationship between changes in the structure of myocardial nerve plexus of the right atrium auricle and myocardial ischemia, parameters reflecting functional status of the heart, and age. A total of 56 females and males aged 20-94 years were investigated. Ischemic heart disease group consisted of 39 persons (their mean age was 63.
