Introduction
Nowadays many specialists in sport pay attention to muscles of respiration training. It is conditioned by the phenomenon, which was called "metaboreflex of respiration muscles" [18]. Its essence is in the fact that muscles of respiration in the state of tiredness cause oxygen decrease in an extremity, brain and heart [4, 5]. According to the research works of Mishchenko V.S. and Andersson P. with other authors, there is some inverse relation between respiratory lungs capacity and the volume of oxygen delivery into functioning muscles [3, 9]. It means that unsufficiently trained respiration muscles can be a stimulating factor for muscles blood supply and as a result make working capacity worse [5].
The mass of breathing muscles is on the average 10-12% from a sportsman's weight and it is a considerable index [4]. At the same time, the research works of McConnell A.K. and Sheel W. together with other authors, during physical load of maximum intensity, revealed oxygen consumption by inspiratory breathing muscles at the level of 16% from the general available volume of oxygen [16,18]. It shows metabolic cost of an organism concerning breathing muscles functioning.
Taking into consideration the information we have, we can suppose that purposeful muscles of respiration training will help to prevent blood supply decrease of working muscles, substratum removal slowing-down will help to decrease the speed
working capacity of a person.
Validity of such kind of hypothesis is proved by several scientific research works in sport.
Great amount of experimental material concerning additional inhalation resistance was accumulated by native [1, 3, 6, 8] and foreign specialists [10, 11, 13, 14, 19].
McConnell A.K. and Kurashvili V.A. showed that muscles of respiration training leads to their functioning effectiveness increase and as a result, helps to increase working time with a standard power to more than 30% [2, 15].
Romer L.M. and Volianitis S. together with other authors stated the increase of sports working capacity among high-class rowers [20] and cyclists [17] to 4.6% owing to systematic inspiratory muscles training.
In the experimental research with the control group of highly-qualified sportsmen McConnell A.K. showed similar effect of everyday 5-minute training of respiration muscles during 5 weeks and an interval training, directed at aerobic endurance development, which was fulfilled also during 5 weeks [16].
Shamardin A.A. stated valid increase of physical readiness and functional abilities of football players (15-16 years-old) from the experimental group to 12,5% in comparison with the control group, where respiratory training wasn't used [7]. More impressive results were received by Suslina I.V. with the group of 13-14-year-old football players,
where the increase of inspiratory muscles power to 28,2% was stated, maximum oxygen consumption (MOC) to 10,5% and the results of Cooper's test to 15,9%, in comparison with the results in the control group of sportsmen, where there were no additional respiratory loads [5].
Taking into consideration all mentioned above, it is obvious that a purposeful strength, power and endurance of respiration muscles development in hockey is prospective as a reserve of sportsmen's working capacity increase [11-13].
The aim of the research: experimental check of an additional inhalation resistance methodology application at the training process of highly-qualified hockey players.
Research methods and research organization
The research works were held since January, 7, 2017 till February, 20, 2017 on the basis of hockey club KHL "Barys" Astana (6 weeks). 29 highly-qualified hockey players took part in the experiment. 17 players had the position of a forward, 9 players had the position of a defender and 3 players had the position of a goalkeeper.
Training lessons were held every day (except 6 rest days) with the help of individual training simulators Power Breathe Fitness Plus Medium. The training effect was achieved by means of inhalation resistance progressive increase. A training simulator helps to vary the load within the range of 23-186 cmH^O • l • sec. -1, which corresponds to 11 levels of difficulty (table 1.1):
Table ^ 1.1 - Comparative table of the load level

During the experiment three tests of respiration muscles were held: 7.01.2017, 20.01.2017 and 20.02.2017. The control was fulfilled with the help of special respiratory equipment Power Breathe K5. The essence of test was in one maximum powerful and at the same time maximum deep inhalation. The
apparatus stated the following indices: index of strength, power (l/sec.), volume of inhalation (l).
Since January, 1 till January, 20 11 training lessons were held, which were directed at respiration muscles development (table 1.2):

Research results
The following results were received during the test among KHL hockey players (table 1.4):
Table 1.4 - Resu ts of tests
Indices 7.01.2017 20.01.2017 20.02.2017
Index of strength 129,59 (± 28,59) 147,93 (± 26,09) 153,62 (± 30,25)
Power (l/sec.) 7,15 (± 1,40) 8,04 (± 1,28) 8,21 (± 1,51)
Volume (l) 4,10 (± 0,78) 4,29 (± 0,57) 4,30 (± 0,59)
The results in table 1.4 show the effectiveness of the created program of respiration muscles training. Purposeful training during 2 weeks with two rest days at the load 0 level helped to achieve on the average 13,84% of progress in the index of strength, 11,73% in power and 6,03% in the volume of inhalation. Further 27 trainings during a month with three rest days provided increase of strength index on the average to 10,35%, power to 9,31%, volume of inhalation to 1,28%.
According to the theory of adaptation an intensive increase of indices was after the first two weeks. Then the results progress became slower, however, during 6 weeks of the training lessons a positive dynamics of indices preserves.
Direction of further research works
Positive influence of purposeful training loads on strength, power and volume of inhalation is shown by the described above experiment. Further it is interesting to study the influence of respiration muscles on hockey players' working capacity and on the speed of an urgent and delayed rehabilitation.

Annotation. Students are considered a population resource, which is not only the factor of well-being, but also the factor of country and its regions safety. In terms of ecological situation worsening, when the principles of healthy life style are not followed, the reserves of nervous, endocrine, immune systems are exhausted there is sickness rate (with temporary disability) increase among students of higher educational establishments. Considerable difference between the information about students' health state and their sickness rate is the result, why there are no integrated unified approaches to the received information gathering, analysis and interpretation. Taking into account the peculiarities of studying at physical culture higher educational establishment, the influence of complex mental and physical loads and also the fact, that students are not only professional sportsmen, but also people, who don't go in for sport and physical culture and even young disabled people, it is necessary to create a special health monitoring program, which is based on a system approach to the following characteristics estimation: educational environment conditions, students' life style and social status, individual morphofunctional characteristics of students' organism development, typological peculiarities of nervous system, mental working capacity, physical qualities and it gives an opportunity to realize in practice individual approach to educational process and students' behavior organization.
