This paper draws a comparison of various functional tests (Letunov's test, Ruffier test, Harvard step test, Kerdo vegetative index, and timed inspiratory (Stange's test) and expiratory (Genche's test) capacity tests, and Romberg's neurological test) carried out among the students of a rather representative group (150 boys and 87 girls aged 17-23), who trained in the picked teams of Saint Petersburg State University (StPSU) in order to further identify those tests that serve the purposes of university sport. It has been established that functional testing in view of the necessity to maintain balance between sports and health objectives is reasonable if limited to the Ruffier test and evaluation of the vegetative tonus at rest using the Kerdo vegetative index. Using the Pearson criterion Χ², we have found a statistical correlation between the Ruffier and Kerdo indices, which can be used for express-evaluation of the current functional state, keeping only to the Kerdo vegetative index.
