Ryšių tarp žmogaus organizmo įvairių požymių paieška yra viena iš aktualių problemų, kurią nagrinėjant galima geriau pažinti tam tikru laikotarpiu irtam tikromis sąlygomis gyvenančio žmogaus vystymosi, egzistencijos ypatumus. Tyrimo tikslas - ištirti 20-22 metų fiziškai ir protiškai aktyvių vyrų fizinio išsivystymo, fizinių gebėjimų ir kai kurių funkcinių rodiklių tarpusavio ryšius. Tirti 36 VPU studentai, kurių amžius buvo 20-22 metai. [...]
A search of a correlation among various features of the human body is one of the urgent problems. Its analysis contributes to a better understanding of the peculiarities of man's development and existence under certain conditions and in a certain period of time. The aim of the present work was to elucidate a correlation among the indices of physical development, physical performance and some of the functional abilities in physically and mentally active male students aged 20-22 years. The study cohort comprised 36 students of the VPU. First of all, the basic indices of their physical development were found (Norton et al., 1996). Physical performance tests included single muscular contraction power (SMCP) (Bosco el al., 1982) and aerobic alactic muscular power (A AMP), 3()s maximal performance on a veloergomelcr ((he maximum power and the mean 30s power) (Imbar et al., 1996) 10s movement frequency (MF). The functional performance of the circulatory and respiratory systems was determined by measuring pulse rate (PR) at rest and applying the Ron Tier index (RI). The aerobic capacity was assessed according to the VO2 max indices, lung ventilation (LV) and working power at the critical intensity limit (CIL). To establish a correlation among the above indices, the Pearson linear correlation coefficient was applied, The Statistica program was used for data processing. The study showed that the students' physical performance under a short-lasting load (SMCP, A A MI' and 30s working power) was predetermined by the basic body constitution indices, which are height and mass. Of all the tests employed in the study, the mosl universal and equivalent to other tests was the Wingate 30s maximum strain test. It showed a very close relation to AAMP, SMCP, lung volume, as well as a reliable, though somewhat weaker, inverse correlation with the RI, PR and diastolic blood pressure. The RI and PR at rest were very closely correlated, equivalent, therefore one of them could be omitted in order to restrict the study program. PR was strongly dependent on VO7 max; the latter index predetermines working power. However, these aerobic capacity indices showed no reliable correlation with other indices under a highly intensive load. Hand movement rate (tapping test) exhibited no reliable correlation with working power while performing a veloergometer test of the same duration.
