Dynamics of general physical capacity and aerobic productivity by veloergometry results of the middle school age girls with weakened vision under the influence of physical rehabilitation

Abstract

Aim of the work is to assess the impact of the rehabilitation complex on the level of general physical capacity and aerobic productivity by the veloergometry results of the middle school age girls with weakened vision. Material and Methods. On the basis of the Zaporizhia Classical Lyceum from September 2015 to May 2016, 90 girls aged 11-14 years were under observation, which had a weakening of visual functions, but with the correct eye position, binocular vision and without organ pathology. Among them were girls with uncorrected visual acuity of 0.1-1.0 and with vision correction up to 1.0. The degree of astigmatism ranged from 0.25 to 1.5 diopters. The distribution of children in terms of the astigmatism degree was the same in all age groups. For physical education classes, they were assigned to the main medical group. To assess the general physical capacity, we chose a test with submaximal exercise power PWC170. Physical performance was evaluated in W. The MOC level was calculated by the formula of VL. Carpman: MOC=1.7ґPWC170 (kgm/min)+1240, ml/min. All those examined were divided into three groups: a control group and two main groups that were suitable for comparison and did not statistically differ in age and degree of visual impairment. They were engaged in the generally accepted school curriculum for physical education. In both main groups, the rehabilitation complex that we developed, which includes special exercises and self-massage of the eyes, special exercises for posture and feet, volitional breath control and aerobic exercises, was additionally offered for practicing on assignment at home. Results and Discussion. In the main groups, in which individual aerobic exercise was assigned, under the influence of the rehabilitation complex the absolute numbers PWC170 and MOC significantly increased, and a strong positive tendency was revealed concerning the surveyed adolescents' body weight, which significantly increased in the course of the school year. Namely, a relative indicator PWC170 increased in the main groups by 5.6% and 5.2% and amounted to 2.05±0.06 W/kg (t=1,52; p>0.05) and 1,99±0.05 W/kg (t=1.71; p>0.05); the MOC component increased by 9.83% and 10.23% and equaled 49.57±1.72 ml/min/kg (t=1.84, p>0.05) and 47.92±1.93 ml/min/kg (t=1.80, p>0.05). The absolute PWC170 rates increased in main groups by 14% and 16.2% to 98.59±4.12 W (t=2.31; p<0.05) and 107.12±4.67 W (t=2.53, p<0.05). Absolute MOC parameters improved in the main groups by 16.5% and 20.6%, amounting to 2619,71±110 mL/min (t=2,49; p<0.05) and 2797,87±118 mL/min (T=2.95, p <0.001). Conclusions. At the primary examination in the control and main groups, statistically significant differences in the indicators of general physical capacity and maximum oxygen consumption were not observed. After the rehabilitation course, the changes in all the studied parameters in the control group were also statistically unreliable. In the main groups under the influence of the rehabilitation complex, the absolute indices of PWC170 and MOC significantly increased, and a pronounced positive trend was revealed cocerning the surveyed adolescents body weight, which increased significantly during the school year. The obtained results make it possible to recommend for implementation a rehabilitation complex containing aerobic exercises for self-practice on assignment at home according to the individual motor regimen.
