Efficiency of the author's technology is determined during the transformation experiment. During the transformation experiment, positive dynamics have been achieved: angular characteristics of the sagital position of posture, which significantly (p <0.05) improve in 11–12 year old boys and girls, with the exception of the body angle of the trunk in 11-year-old boys, changes that are statistically not significant (p> 0.05): at the age of 11 years the angle of inclination of the head decreases in boys by 19,8%, in girls – by 16,6%; the angle of inclination of the body decreases in the boy by 4,8%, in girls – by 2,3%; at the age of 12 years the angle of inclination of the head decreases in the guys by 18,2%, in girls – by 16,2%; the angle of inclination of the body decreases in the boys by 1,2%, in girls – by 0,6%; the vertical stability of the body, among which the values of the static balance of the body (in the closed eyes test) were significantly increased (p <0,05) in boys and girls aged 11 years old, respectively, by 22,6 and 26,9%, respectively, and at the age of 12 years old in 21,2 and 22,6%, and the static balance of the body (in the open-eyes test) in boys and girls aged 11 years old – respectively, by 34,6 and 36,3 %, and at the age of 12 years old – by 27,4 and 24,8%; Static endurance of the muscles of the front of the body and legs. These indicators were significantly (p <0,05) increased in boys aged 11 years by 4,0%, at the age of 12 years – by 4,6 %, in girls aged 11–12, the increase was 30,2% at each age; Static endurance of the muscles of the back of the trunk and legs. The indicators were significantly (p <0,05) increased in boys aged 11 years old by 3,6%, at the age of 12 – by 4,5 %; in girls aged 11 years old – by 4,0% and at the age of 12 – by 3,1%. The results obtained show improvement of the posture status. The analysis of the results of physical fitness gives grounds to state that in schoolchildren of 11-12 years, the indicators of strength, speed-strength qualities, speed and agility have significantly improved (p <0,05). The exception is only an indicator of flexibility that undergoes significant (p <0,05) changes only in boys aged 11 and girls aged 12 years old. Statistically significant (p <0,05) also improved the index of Quetelet. The conducted pedagogical experiment confirmed the effectiveness of the technology of correcting the disturbances of posture of 11–12 year-old schoolchildren with hearing impairments using the means of health fitness in the process of adaptive physical education.
