AbstractThe aim of the study was to determine how physical activity affected the physical fitness and body composition of the blind and visually impaired.The study included 28 male students from the Lower Silesia Special Educational Centre No. 13 for the Blind and Visually Impaired in Wroclaw, aged 18–22 years, with disability degree certificates. The subjects were divided into two groups: physically active men (TR,Men engaging in additional forms of physical activity presented significant (Additional physical activity undertaken by the visually impaired has a positive effect on their physical fitness, namely and primarily on their flexibility, functional strength, speed, arm movement speed, jumping ability, and the strength of the abdominal muscles. Moreover, additional physical activity significantly affects the overall and segmental body composition in the lower limbs and the right upper limb.

AbstractIntroduction. In elite sport, athletes are required to maintain appropriate body posture control despite a number of destabilising factors. The functions of body posture control are monitored by the central nervous system that constantly receives information from the vestibular and somatosensory systems as well as from the visual analyser. Visual impairment may contribute to a decrease in the level of motor abilities and skills; however, it does not prevent visually impaired individuals from taking up physical activity. Therefore, this study sought to assess the static balance of visually impaired goalball players and shooters. Material and methods. The study included 37 goalball players and 20 shooters. A force platform was used to assess static balance. The study participants performed tests: standing on both feet with eyes open (BFEO) and closed (BFEC) (30 s), single left- and right-leg stance with eyes open (SLEO and SREO) as well as single left- and right-leg stance with eyes closed (SLEC and SREC). Statistical analyses were carried out using the following parameters: centre of pressure (CoP) path length [cm], CoP velocity [m/s], and the surface area of the stabilogram [cm2]. Results. No significant differences were found between goalball players and shooters in static balance levels. However, such differences were observed after taking into account the number of athletes who were capable of performing particular tests. Conclusions. The findings indirectly confirm that there is a correlation between the type of physical activity and balance levels in visually impaired individuals. Further research ought to include tests performed on an unstable surface.

Abstract Background: Older adults with visual impairments experience a higher risk of falling, and are more vulnerable to adverse health consequences associated with falls than those with normal vision. This study aims to characterize the longitudinal changes of objectively measured physical activity and self-reported fear of falling (FoF) related to types of falls in visually impaired older adults. Methods: We obtained data from the Falls in Glaucoma Study (FIGS), a prospective cohort study that recruited 234 participants at the Johns Hopkins Wilmer Eye Institute from 2013 to 2015. Falls were defined as unintentionally coming to rest on the ground or a lower level, and injurious falls were determined though follow-up calls. Study participants were categorized into three groups – fallers with injurious consequences, fallers without injurious consequences, and non-fallers based on fall status in the first year. Physical activity was assessed using a waist-bound accelerometer (Actical). FoF was evaluated by questionnaire, with Rasch modeling generating FoF scores where higher scores reflected worse FoF. The three-year longitudinal changes of physical activity and FoF were modeled using mixed-effects models. Results: In linear models fully adjusted for visual field damage and other covariates, physical activity among injurious fallers declined 425 steps/year (95% confidence interval [CI]: -793, -57), 13 active minutes/year (95% CI: -21, -6), and 3 minutes/year of moderate/vigorous activity (95% CI: -5, 0) more over the three-year study period compared to non-fallers; however, physical activity did not decline among non-injurious fallers. No longitudinal increases in FoF scores were observed in injurious or non-injurious fallers.Conclusions: Among visually impaired older adults, injurious falls identified prospectively over 12 months contributed to a significant decline in physical activity over a three-year period, while no significant increases were observed for FoF. Further longitudinal research is warranted to better understand how different groups respond to falls, either via behavioral changes and/or changes in FoF, and to characterize the impact of reduced physical activity in fallers.
