چکیده
Objective. The main purpose of the research was to develop a coefficient cardiorespiratory system status, which will take into account both frequency and power characteristics external respiration hemodynamics activity. Compare an informativeness this with universally accepted Hildebrandt one.
 Materials Methods. 154 apparently healthy young people sexes were examined. On bicycle ergometer pedaling rhythm 40 per minute, five standard stages short-term physical exercise load ranging from negligible moderate provided. Spirography, tonometry pulsometry carried out before loading, at its peak after it. parameters specified recorded for each subject simultaneously. Systolic volume calculated using Starr formula subsequent defining cardiac minute output.
 Statistical analysis performed Statistica ® 7.0 package (StatSoft Inc., USA). Assessment results’ significance Student's t-test sign test.
 Results. In case low exercises pulmonary ventilation is increased due greater reactivity breathing amplitude lesser extent change in respiratory movements. This type reactions component interaction more efficient. given conditions, body’s adaptation ensured by dominance, while responses systemic arterial pressure pulse turn be less pronounced, stabile. Taking adaptive importance changes cardiovascular activity, status proposed – MBV/RMV (ratio blood flow volume). factor demonstrated have significantly informative value sensitivity generally recognized coefficient.

Background. The study aims to determine position-specific loads by different tactical strategies. Eighty Turkish Super League U21 players (19.35 ± 1.6 years, 179.4 ± 2.3 cm, 75.6 ± 4.1 kg; M ± SD) were involved in this study. Objectives. The players completed eight different 11v11 training games. While one team practiced the ball possession and “defense as a team” strategy, the other team impl...

During a 2-year period, 31 cases of a hereditary retinal degeneration in dogs bred in India were found mainly suspected for progressive retinal atrophy (PRA) with typical history of initial nyctalopia followed by hemeralopia. Out of 31 PRA suspected dogs, 8 dogs (26%) were from the age group of 1-5 years, 15 (48%) 6-10 years and the rest (26%) 11-15 years. The most predominant breed was Spitz (...
