Introduction<\/strong><\/p>\n

It is known that an increase in physical activity can increase the efficiency of the body’s functioning under conditions of norm1<\/sup>and pathology2<\/sup>.\u00a0 This is achieved as a result of regular physical education and sports by optimizing the general functional state and social adaptation at\u00a0any age3,4<\/sup>.\u00a0 It is possible to interest young people especially with health disorders in high physical activity by involving them in systematic sports games5<\/sup>.\u00a0 Due to the increase in physical activity on an ongoing basis, young people achieve a functionally beneficial improvement in the\u00a0indicators of the cardiorespiratory system and overall vitality6<\/sup>.\u00a0 The results of a systematic assessment of the effectiveness of various restorative methods of health-improving physical culture in all cases confirm this opinion7,8<\/sup>.\u00a0 In this regard, in modern conditions, it becomes very\u00a0important to improve the methods of health improvement in adaptive sports, which should be aimed at achieving effective systemic integration of patients and disabled people into society and their involvement in professional activities9,10<\/sup>.<\/p>\n

Studies conducted in recent years have shown that the use of special complexes of physical activity in the framework of adaptive sports focused on certain types of diseases can significantly increase the adaptive reserves of the body of physically trained patients and disabled people 11,12<\/sup>.<\/p>\n

Patients with sensorineural hearing loss of varying severity are attracting great attention of coaches in adaptive sports13<\/sup>.\u00a0 As a rule, they have low indicators of the development of physical qualities, low working capacity and are poorly socialized14<\/sup>. At the same time, regular training in adaptive sports has a very positive effect on their locomotor function and general physical conditions15,16<\/sup>. As a result, a very promising direction in adaptive sports for people with hearing impairments is now being formed17<\/sup>.<\/p>\n

Purpose of the study: to assess the influence of adaptive handball training on the motor characteristics of adolescents with sensorineural hearing loss of I-II degree.<\/p>\n

Material and Methods<\/strong><\/p>\n

This study was supported at a meeting of the local ethics committee created at the Russian State Social University on September 15, 2017 (protocol \u211611).<\/p>\n

The study involved 13-14-year-old male adolescents with a confirmed diagnosis of sensorineural hearing loss of I-II degrees, a total of 31 people.\u00a0 Of these, two groups were formed.\u00a0 The first group is the observation group (14 adolescents) who expressed a desire to start practicing adaptive handball and who started training.\u00a0 The second group – a comparison group (17 adolescents), consisted of persons who preferred to engage in physical education in the classroom in a secondary school (special medical group).\u00a0 In carrying out this study, the results of the annual medical examination, the results of functional tests in the examined adolescents and the results of assessing their control standards of physical fitness were used.\u00a0 The study was carried out in 3 stages:<\/p>\n

Stage 1 – the formation of a control group and a group of young men to practice adaptive handball, taking into account their personal consent to engage in adaptive sports and in the presence of an occupational pathologist’s admission to these activities.\u00a0 An initial test of the physical fitness level of all subjects was carried out.<\/p>\n

Stage 2 – assessment of the dynamics of indicators in the control and in the group of people engaged in adaptive handball after 6 months.<\/p>\n

Stage 3 – analysis of the results obtained, determination of the dynamics of the physical state in both observation groups.<\/p>\n

Statistical processing of the indicators of both study groups was assessed by the methods of variation statistics using the program “Stat Soft, Inc.”\u00a0 USA.\u00a0 The significance of differences in quantitative characteristics between the groups was assessed using the Student’s t test.\u00a0 Correlation analysis was performed using Pearson’s correlation coefficient.<\/p>\n

Results and Discussion<\/strong><\/p>\n

At the beginning of the study, the initial level of physical fitness of all the surveyed was determined (table).\u00a0 The state of the registered initial speed-strength qualities was determined in the tests: 30 m running (5.8\u00b10.7 s), 60 m running (10.2\u00b11.1 s), standing long jump (1.69\u00b10.14 m).\u00a0 The initial state of endurance development in the study was judged by the distance that the subjects were able to overcome in 6 minutes running (980.0\u00b170.0 m).\u00a0 The severity of strength\u00a0qualities in the outcome was judged by the number of pull-ups on the bar (5.4\u00b13.8 repetitions).\u00a0 The development of coordination abilities in adolescents in the outcome was judged by the results of shuttle running 4×6 (10.9\u00b11.7 s) and by the number of jumping rope jumps for 25 s (27.0\u00b19.4 repetitions).\u00a0 The results obtained in adolescents made it possible to speak of an insufficient initial level of development of their physical capabilities.<\/p>\n

By the end of the observation in the comparison group, there were no significant changes in all considered indicators.\u00a0 As a result of regular handball in the observation group, after 6 months, a significant increase in the level of physical development was achieved (table).\u00a0 This was judged by an increase in speed-power qualities (acceleration of a 30-meter run by 23.4%, an acceleration of a 60-meter run by 20.0%, an increase in the long jump distance from a standing\u00a0position by 17.7%), an increase in power qualities\u00a0 (an increase in the number of pull-ups on the bar by 1.5 times, an increase in the number of lifts of the trunk from a prone position in 1 minute by 34.6%), according to the activation of coordination abilities (acceleration of shuttle running by 18.5%, an increase in the number of jumps performed using a rope\u00a0 in 25 seconds by 42.9%), as well as by increasing endurance (increasing the distance covered during 6 minutes of running by 12.4%) over the entire observation period.<\/p>\n

During physical training in the observation group, the following technical elements turned out to be the most difficult to master:<\/p>\n

High-speed movement with a given vector of a sharp change in the direction of movement;<\/p>\n

Movement backwards along a given trajectory;<\/p>\n

Performing running exercises with abrupt start and stop;<\/p>\n

Execution of throws of the ball and reception of the ball in motion and when jumping with a change in the trajectory of movement;<\/p>\n

Execution of false movements with the simultaneous execution of throws and ball reception.<\/p>\n

At the beginning of the training sessions in the experimental group, there was a rapid fatigability of the trainees, which was expressed in an increase in errors when performing dynamic complex coordination exercises, in a decrease in attention and in a decrease in speed indicators.\u00a0 A characteristic feature of mastering the game elements of adaptive handball in the observation group was the presence of a statistically significant correlation between an increase in results in shuttle running and running with a sharp change in the direction of movement vector (r = 0.655; p<0.047).\u00a0 An increase in the effectiveness of rope exercises fulfillment per unit time\u00a0showed a significant correlation with the performance of jumping and throwing elements (r = 0.509; p <0.049).\u00a0 Pronounced changes in the increase in speed qualities in the form of sharp accelerations when running along a given trajectory had a correlation relationship with an increase in the distance covered during standing jumps (r = 0.619; p<0.042).<\/p>\n

After 6 months of training, the observation group showed a statistically significant decrease in the level of fatigue.\u00a0 This was confirmed by subjective sensations and dynamics of the heart rate, which corresponded to the optimal values \u200b\u200bthroughout the exercise (heart rate 119.0\u00b110.0 beats per minute).\u00a0 The most difficult to learn for adolescents in the observation group were the simultaneous execution of jumping and throwing movements, as well as the simultaneous transmission and reception of the ball in the process of movement.\u00a0 A positive\u00a0effect in mastering the reception and transfer of the ball and throwing the ball into the target was observed when outdoor games with throwing elements were included in the structure of occupations against a background of high emotional uplift and in the absence of strict regulation of ball possession.\u00a0 A significant decrease in gross errors in the technique of ball handling and in\u00a0the implementation of jumps, as well as an increase in the effectiveness of throwing the ball at the target, achieved in the observation group after 6 months of regular training, apparently, should be associated with the achievement of an increase in the level of general physical readiness with a significant increase in the general development of basic physical qualities18,19<\/sup>.<\/p>\n

During the registration of locomotor stability under the influence of external factors, it was possible to reveal that the time to cover a distance along a given trajectory with resistance to the defense of the opposing team was somewhat reduced.\u00a0 This indicated an increase in their muscle activity20<\/sup>and an increase in the available arsenal of movements and an increase in the level of\u00a0general physical fitness21<\/sup>. In addition, in the observation group, after 6 months of training, an increase in locomotor stability was noted with a situational change in the direction of movement, transmission and reception of the ball, which should be associated with the activation of vestibular and muscular mechanisms that ensure an increase in body stability in space22<\/sup>.<\/p>\n

Conclusion<\/strong><\/p>\n

The positive effect of increased physical activity on the overall functional state of the body has been the subject of many studies.\u00a0 It is most realistic to achieve this in adolescents through systematic sports games.\u00a0 They provide an effective increase in physical activity and improve the performance of the cardiorespiratory system.\u00a0 As a result of regular six-month sessions of adaptive handball in adolescents with sensorineural hearing loss, it was possible to achieve a significant increase in the level of development of strength characteristics, speed-strength qualities, coordination abilities and endurance.\u00a0 Regular visits to physical culture lessons by another group of their peers with a similar pathology could not provide reliable dynamics of all the considered indicators, keeping them at their initial low level.\u00a0 It can be considered that systematic training in adaptive handball can have a pronounced positive effect on the development of locomotor capabilities and the general level of physical fitness in adolescents with sensorineural hearing loss.<\/p>\n
