| Summary: | The study was aimed to establish the aerobic capacity of women aerobics athletes of different age and different mastership, physiological changes and energetics during competitive activities. The main conlusions are as follows:
1. The aerobic capacity of representatives of aerobic gymnastics is by 25% higher the norm values of girls of similar age but it is considerably (about 35 %)) smaller than the respective indices of athletes developing endurance. The absolute VO2max during continuous incremental treadmill test is 2.5 l/min (95% CI [2.2 – 2.8]; the relative one – 45 ml/kg/min, CI [41.6 – 48.0],the maximum pulmonary ventilation reaches 87 l/min, CI [78.0 – 95.1], and the maximum HR – 190 beats/min, CI [183.6 – 197.0]. The first ventilation threshold VE manifests itself O2 consumption having reached 74% of the maximum wren HR is – 171 beats/min or 90% of the maximum.The maximum and submaximum respiratory gas exchange and HR values during the continuous incremental treadmill test were similar (p>0.05) in groups of aerobic gymnastics with different level of training.
2. The telemetric registration and analysis of respiratory gas and HR has shown that changes in the form of the exponent are typical for all the indices mentioned when after a fast increase at the onset of the exercise they become nearly stabilized. The rate of changes in separate indices is not the same. Thus, the fastest change occur in HR.VO2 changes slower and VE – the slowest with time constant being 17.2... [to full text]
