IMPROVEMENT OF AEROBIC ENERGY SUPPLY PROCESSES IN 37-49 YRS OLD WOMEN BY MEANS OF COMPLEX AQUA-FITNESS TRAININGS’ AND METHODIC OF ENDOGENOUS - HYPOXIC BREATHING’S APPLICATION

. Purpose: substantiation of purposefulness of complex aqua-fitness training and methodic of endogenous-hypoxic breathing’s application for improvement of women’s functional fitness. Material: in the research 13 women of control group and 12 women of experimental one, who had never trained aqua-fitness earlier, participated. (Their age was 37-49 years old). Results: during 24 weeks, at different stages of the research (after 8, 16 and 24 weeks from the beginning of trainings by the worked out program) we determined indicators of power (maximal oxygen consumption) and capacity (threshold of anaerobic metabolism), which characterize aerobic processes of energy supply. Conclusions: it was proved that complex application of aqua-fitness trainings in combination with methodic of endogenous-hypoxic breathing is effective. It is witnessed by acceleration of increment of absolute and relative indicators of workability, maximal oxygen consumption and threshold of anaerobic metabolism.

For registration of physical workability of the tested persons we used bicycle stress test PWC170 with bicycle stress device «ВЭ-02».By its results we determined maximal oxygen consumption VO2 max (V.L. Karpman et al. [3,6,11].Control over heart beats rate we conducted with the help of heart beats monitor "SIGMA SPORT PS 4" and pulsetacho-graph BEURER PM70. For characterizing of efficiency of aerobic energy supply systems we used test for determination of threshold of anaerobic metabolism (TAM) which was offered by group of scientists under guidance of Conconi (1982) [11].
For analyzing of influence of complex aqua-fitness and endogenous-hypoxic breathing influence on indicators of aerobic energy supply systems we conducted statistic processing of the received data by t-criterion of Student [3].Difference was regarded as confident at level of significance of p<0.05.

Results of the research
Results of study of efficiency of women organism's energy supply systems permit to affirm that aqua-fitness trainings in combination with creation in organism condition of normobaric hypercapnic hypoxia cause positive changes in power (PWC170, VO2max) and capacity (TAM) of aerobic energy supply processes.
Mean values of these indicators before trainings in control (CG) and experimental (EG) groups did not confidently differ (see table 1).During 8 weeks of trainings there did not appear any confident changes (р>0.05).

It should be noted that at this stage of the experiment we registered confident difference between mean values of absolute indicators of anaerobic metabolism threshold in control and experimental groups (see table 1).
By the end of 24-weeks' training cycle we found that complex application of aqua-fitness trainings and methodic of endogenous-hypoxic breathing facilitated further increasing of indicators of aerobic energy supply of 37-49 years old women's organism.In experimental group mean values of workability absolute indicators, maximal oxygen consumption and threshold of anaerobic metabolism increased confidently by 28.78%, 12.37%, and 23.97%, comparing with initial data.Relative indicators increased by 38.91%, 20.64%, and 33.55% (see table 1).In CG aqua-fitness trainings facilitated confident increase of mean values of absolute and relative indicators of physical workability -by 16.13% and 24.02%.Absolute indicator of maximal oxygen consumption increased by 6.88% (see table 1); absolute value of TAM -19.49% (p<0.05) while relative -by 27.56% (p<0.05)(see table 1).Absolute indicator of maximal oxygen consumption in this group increased by 6.88% (p<0.05).Relative value remained unchanged, comparing with initial data (p>0.05)(see table 1).
It should be noted that 24 weeks' cycle of aqua-fitness trainings in combination with methodic of endogenous hypoxic breathing and without it facilitated improvement of organism's aerobic efficiency in 37-49 years old women (judging by criteria of Ya.P. Piarnat from "good" to "excellent").

Discussion
The obtained results of control group prove the data of previous researchers [5,7,10], concerning effectiveness of aqua-fitness's application for improvement of women's functional fitness.For the first time, we used methodic of endogenous hypoxic breathing in combination with aqua-fitness trainings of 37-49 years old women.Results of experimental group witnessed purposefulness of complex application of endogenous hypoxic breathing and aqua-fitness trainings for acceleration of increasing of aerobic energy supply systems' indicators.

Conclusions:
Results of the conducted researches witnessed that health related aqua-fitness trainings facilitate confident increase of physical workability indicators, maximal oxygen consumption and threshold of anaerobic metabolism.In its turn it witnesses about improvement of 37-49 years old women's functional fitness.Complex application of aqua-fitness and endogenous hypoxic breathing facilitates acceleration of the above described changes in power and capacity of aerobic energy supply processes.It proves purposefulness of their application in health related trainings of 37-49 years old women.
Further researches shall be oriented on studying of influence of complex aqua-fitness and EHB application on physical condition of 30-49 years old women.

Table 1
Difference in effect of trainings became noticeable after 16 weeks from the beginning of finalizing test (see

table 1 )
. For the mentioned period in CG women only mean values of absolute physical workability increased (by 14.90%) and maximal oxygen consumption -(by 6.35%).In experimental group both absolute and relative values of these indicators confidently increased.Absolute and relative values PWC170 increased by 21.49% (p<0.05) and 29.61% (p<0.05),VO2max-by9.24%(p<0.05)and 16.23% (p<0.05)(seetable1).Complex application of aqua-fitness and EHB facilitated confident increasing of mean values of absolute and relative indicators of anaerobic metabolism threshold -by 18.49% and 27.10% (see table1).
