Abstract

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 et al., 1982) and aerobic alactic muscular power (AAMP), 30s maximal performance on a cycle ergometer (the maximum power and the mean 30s power) (Imbar et al., 1996) lOs movement frequency (MF). The functional performance of the circulatory and respiratory systems was determined by measuring pulse rate (PR) at rest and applying the Roufier 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, AAMP 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 most universal and equivalent to other tests was the Wingate 30s maximum strain test. It showed a very dose 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 VO2 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 cycle ergometer test of the same duration. Verf.-Referat
