With the help of the 94Fifty technology we were able to analyze the three-point shot. We were curious to know whether the majority of the shots are recommended by the manufacturer of the measuring system and carried out in preplanned intervals of entry angles, the rotation of the ball, and the release time of the ball, and we wished to find out the consistency of the aforementioned parameters between the guards and other players. The hypotheses were tested on a sample of 52 great male basketball players, aged 18 and 19. We deducted that most of the shots from the distance of 6.75 m occur under a entry angle greater than 42°, but not in the estimated interval (between 42° and 48°); that most of the shots do not occur in the estimated interval of the rotation of the ball (from 130 to 150 revolutions/minute); and that most of the shots do not occur in the estimated interval of the release time (< 0.7 seconds). When it comes to the consistency of the before mentioned parameters we did not find any discrepancies between the guards and other players. Based on the results a question arises: did the manufacturer of the measuring system adequately form the intervals of the aforementioned parameters or does the problem lie in the performance of the shots by the chosen players?
Studies of the familial association of physical activity (PA) and sedentary behavior (SB) have increased in recent years. However, there is a lack of studies that have objectively examined the correlates between parents, grandparents, and childrens' PA. Therefore, the purpose of this study was to measure PA using accelerometers to determine the extent to which PA and SB correlate among parents, grandparents, and children. A sample of 169 children between 11–14 years (77 boys and 97 girls), 225 parents (98 males and 127 females) and 52 grandparents (16 males and 36 females) were recruited for the current study. Accelerometers RM42 (UKK Terveyspalvelut Oy, Tampere, Finland) were used to determine PA levels of children, parents and grandparents. Epoch was set to 1 s. Mothers' moderate-to-vigorous PA (MVPA) was associated with children's MVPA (p < 0.05). After adjusting for age, BMI (child), and educational status, the results remain the same. Results of linear regression analyses for boys' sedentary time showed that fathers' sedentary time was significantly associated with boys (p < 0.01), but not with girls. The association of grandmothers' and grandfathers' MVPA activity with that of children showed that grandparents' MVPA, when adjusted for age, BMI, and educational status, was not a significant predictor (p > 0.05) of children's MVPA (total sample). In contrast, grandfathers' sedentary behavior was a significant predictor (β = 0.269; p < 0.05) of children's sedentary behavior (total sample). The results of the current study suggest that parental involvement in PA, particularly by mothers, is important for children's PA and, accordingly, healthy outcomes.
There is evidence that physical activity (PA) can improve the academic performance. We recruited healthy adolescent girls, aged 11–12 years, and measured their PA with the accelerometer ActiGraph GT3X for the consecutive 5 days. Physical fitness (PF) was measured with eight motoric tests and three anthropometry measures. Academic performance (AP) was assessed for the six academic narrated school subjects. The results revealed that the girls were more physically active during the week days and less active at weekend (557 vs. 516 counts/min). Physical education grade shows the highest overall correlations with the results of the PF test battery (r = 0.53–0.95, p < 0.01). Nevertheless, correlations surprisingly decrease for the combined daily PA (r = 0.45), especially the weekend PA (r = 0.28). Grade point average and PF correlated moderately (r = 0.43-0.64), while they were moderate to high for PA (r = 0.59–0.87). Many questions arose after the completion of the present study and several new topics opened up, such as the question of how parental education affects the duration of PA and AP of the children and the influence of the place of residence AP of the children.
SummaryElite athletes invest most of their time and energy in sports training and competitions, so they are often absent from the pedagogical process at university levels of education, which has an impact on the achievement of education. Too often, top-notch athletes are faced with difficulties in building out-of-sports careers, since many have no proper education and necessary experience. It is therefore important that they acquire an education at a time when competing in sport. At Faculty of economics, University of Ljubljana we’ve developed a system that facilitate education and help students with athlete status to achieve the desired vocational education, despite their intensive involvement in the top sport.
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.
