Assessment and Management of Cardiorespiratory Deconditioning with Beninese Visually Impaired Subjects
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2019, Vol 19, Issue 2
Abstract
This study examined the effects of a short training program on cardiorespiratory condition of visually impaired subjects. A total of 53 visually impaired pupils and students in classes B1 = “blind” and B2 “visually impaired” from Benin participated in this study. The submaximal YMCA method was used to obtain accurate and reliable information about the VO2max of visual impaired subjects. This is a pilot study that surveyed the cardiorespiratory condition of the subjects on a cycloergometer before and after 15 workoutsof 30minute each. 68% of visually impaired subjects initially obtained an VO- 2max estimate that is very significantly less than 25 mL.kg-1.min-1. All subjects reduced their average exercise heart rate by 13 bpm with average Borg scores of 18.50 (very difficult) for girls and 14.91 (difficult) for boys. The subjects that took part in the study significantly improved their VO2max by 24.31 ± 07 mL.kg-1.min-1for girls and 23.72 ± 10.6 mL.kg-1.min-1forboys (P <0.05). This study showed that total or partial loss of visual function is not a limiting factor in improving the cardiorespiratory capacities of visually impaired people. No correlation was found between the seriousness of the deficiency and the low level of VO2max of the visually impaired.

Keywords: Visual Impairment; YMCA Test; Cardiorespiratory Deconditioning; Benin Introduction In many African countries in general, especially in Benin, being handicaped results in an image of irreducible disability. Despite the legal arsenal in their favor, these people experience situations of exclusion from the practice of Sport and Physical Education [1] due to a deficiency. Thus, they are generally constrained to decubitus and immobility with cardiorespiratory and musculoskeletal complications. According to WHO in 2010, physical inactivity is the 4th risk factor for overall mortality. Visually impaired people are consistently referred to as those with very low physical activity, unlike other normal children. Prolonged decubitus sometimes leads to exercise mismatch with changes in skeletal muscle that may aggravate a pre-existing heart failure, a bronchial congestion, and even low respiratory infections [2,3]. De Potter (2006) reports that the physical condition of the visually impaired person is less than normal and correlated with the seriousness of the impairment. Despite these known complications, no study in Benin has investigated on the methods of caring for this category of people. Visually impaired people account for 37.4% (4.8% of blind people and 32.5% of visually impaired people) in the total population of persons with disabilities, estimated at 102 997 according to the third general population and habitat census of February 2002. However, they are aware of their ability to practice several sport activities with technical and human assistance. Unfortunately, the level of care for this category of people is low or non-existent in adapted physical activity programs. Therefore, the particular interest of this study is based on subjects with visual impairment, thus a disability that can limit their autonomy, their ability to develop motor skills and functional abilities. The study attempts to answer the lack of a simple method allowing the visually impaired (VI) to autonomously improve his cardiorespiratory condition on the cycloergometer.
