The aim of the research was to determine the influence of sprint performance and explosive strength on ball throwing velocity in Goalball. The sample of participants consisted of 12 nationally and internationally ranked Goalball players, with an average age of (25.17±8.03). To evaluate sprint performance, the 5 and 10 meter sprint tests were used. To evaluate explosive strength, the standing long jump and seated medicine ball throw were used. The results of the regression analysis have indicated that the entire system of applied variables is statistically significantly connected and influences ball throwing velocity. At the same time, we evaluated the statistically significant influence of the seated medicine ball throw variable. We can conclude that as part of the fitness training of Goalball players, it is necessary to work on improving sprint performance and explosive strength due to the ability of rapid transition of the players from the defensive phase to the attack phase. It is especially important to develop upper-body explosive strength in order to increase ball throwing velocity and create the possibility for greater effectiveness of Goalball players.
Quality of life is a broad and complex construct. World Health Organization refers to it as an "individual's perception of their position in life (…) in relation to their goals, expectations, standards, and concerns". Reduced visual functions have a negative impact on the overall individual's functioning. Difficulties in accessing visual information and problems in orientation and mobility create significant limitations in performing daily activities and lead to diminished opportunities for education, work, social participation, and leisure. Limited participation in the aforementioned areas with lower social interactions have a negative impact on the individual's quality of life. However, it is unclear whether this construct of people with visual impairment is compromised due to reduced ability to perform daily activities or due to difficulties in establishing social interactions. Objectives. In an effort to indicate the consequences of visual impairment on quality of life, the goal of this research was to determine the objective quality of life in adults with different visual status when controlling the age. Methods. The Comprehensive Quality of Life Scale was used to evaluate the quality of life. The sample consisted of 175 people - 92 participants with visual impairment and 83 participants without structural or functional problems in the visual system. Results. Results of eight one-way ANCOVAs indicated a significant effect of visual status on Objective quality of life in total (p < .001) and on its four domains: Material well-being, Health, Productivity, Place in Community. Conclusion. The effects of different visual status on the observed construct revealed when age as a variable is controlled.
As a contemporary educational tendency, inclusion captures a great deal of attention from researchers, and hence there are numerous studies dealing with various aspects of this process. This paper is aimed at studying whether experience in work with children with impaired vision and training for work with children with disabilities lead to differences in teacher evaluations of: (a) the problems the children with impaired vision are facing in regular school; (b) readiness of regular school for inclusive education of this group of children. The sample comprised 63 teachers in regular secondary schools: 54% have had previous experience in working with children with impaired vision, while 42.9% attended training for work with children with disabilities. The results of two-factor analysis (ANOVA) suggest that teacher experience and training have an independent effect on their evaluations. Compared to the teachers without experience in work with visually impaired children, the teachers who have had this experience evaluate considerably lower the problems of adaptation and students’ fitting in school environment, complying with the demands of compulsory curriculum and the level of teacher education, while they evaluate much higher school readiness when it comes to the level of training of teaching staff. The teachers trained for work with children with disabilities evaluate lower than teachers without previous training the student problems in the accomplishment of the compulsory curriculum and much higher teacher training, adjustment of textbooks and teaching aids. The obtained findings indicate that teacher experience and training play a significant role in teacher readiness for inclusive education
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
