In Lithuania, over the recent years a highly-skilled heptathlon athlete has been developed. She made her international debut in the Sidney Olympic Games in 2000 and took the 12 th place. Every year she kept improving her skills and excellently prepared for the XXVIII Olympic Games in Athens where she won a silver medal. Track-and-field heptathlon requires excellent physical fitness, development of all specific features, as well as good physical fitness for each contest. While planning the process of a heptathlon athlete’s training, it is most important to elaborate an optimum structure of an annual cycle with regard to the competition schedule and the individual potential of human adaptation. To be able to control the process, it is necessary to monitor the dynamics of the physical and functional abilities of the athlete in different periods of the annual cycle of training. The aim of the study was to analyse the dynamics of sports results of the Lithuanian heptathlon athlete A. S. in a four- year Olympic cycle and the dynamics of her physical and functional abilities over this period. We analyzed the dynamics of the sports results of A. S. over the last five years. Her body composition indices were measured in laboratory, with determining psychomotor response time and movement frequency per 10 s. To determine her physical abilities, we measured her single muscular contraction power (SMCP), anerobic alactic muscular power (AAMP). A running-track was used to establish the intensity of energetic processes at the anaerobic threshold level, with measuring heart rate (HR), running speed (km / h) and blood lactate concentration. The functional capacity of the circulatory and respiratory systems was assessed by the Roufier index (RI). Anaerobic capacity was measured with a gas analyzer at the critical intensity and anaerobic metabolism limits. The sports results of A. S. kept improving every year except 2003. In the 2004 Olympic Games she gathered 6435 points and won the second place. In previous years, in separate ...
