Objectives: The research aimed to determine the structure of functional abilities of folk dancers. Methods: In order to determine the structure of functional abilities, 100 dancers of the Academic Folk Ensemble "Oro" of the Student Cultural Center of Nis were tested. The dancers ranged in chronological age from 18 to 27 years. The average dancing experience of the dancers was 8 years, while the continuous multi-year training process implied three sessions per week. For the assessment of functional variables, systolic (FBPSYS) and diastolic (FBPDIA) blood pressures were measured. Pulse rate at rest (FPURE) was determined by palpating the respondents` carotid artery after their 15-minute rest in a sitting position, and the number of beats in 15 seconds was multiplied by 4. Thus obtained frequency per minute was taken for processing. All the data in this study were processed at the Multidisciplinary Research Center of the Faculty of Sport and Physical Education, University of Pristina through the system of data processing software programs DRSOFT developed by Popovic, D. (1980), (1993) and Momirovic, K. & Popovic, D. (2003). Results: Pulse frequency during physical exertion (FPUEX) was measured in the sixth minute of riding a cycle ergometer. Maximal values of oxygen uptake VO2max, (FO2LM) and (FO2ML), or absolute and relative values, were determined by Astrand`s indirect method (Zivanic et al., 1999). Conclusions: The factor structure of functional abilities was analyzed on the basis of all the information provided by a matrix of significant principal components (Table 1). Based on the Guttman measure6, three characteristic roots (three latent variables) which explained 83.08% of the common variance were obtained.
