In the context of the COVID-19 pandemic, the need arose for replacing conventional forms of education with remote classes. Therefore, it was decided to test the effectiveness of a social skills workshop conducted using active online methods for second-year physiotherapy students.</p> <p><italic>Material and methods</italic>: The experimental factor was the contents of workshop classes taught online as part of the mandatory course included in the curriculum. The platforms Teams, Zoom, and the Messenger were used to carry out the experiment. The workshops used active learning methods: simulation of work situation, drama, peer feedback and interaction-based communication.</p> <p><italic>Results</italic>: The results obtained from 78 participants (pre-test and post-test, including 45 women) were analyzed. The age of the participants ranged from 20 to 22 years, with a mean of 20.7 years.

The predictors in this study included measures of generic power, speed, agility, and anthropometrics. The univariate and multivariate relationships among the predictors and the criteria (futsal-specific change-of-direction speed and futsal-specific reactive agility) were assessed by using Pearson’s correlations and multiple regression analysis, respectively.</p> <p><italic>Results:</italic> The predictors were poorly related to the different facets of agility (all trivial to moderate correlations). Multiple regression models were not successfully cross-validated for any of the types of agility performance.</p> <p><italic>Conclusion:</italic> Generic power, speed, agility, and anthropometrics are not valid predictors of futsal-specific change-of-direction speed and futsal-specific reactive agility. As these futsal performances were used to mimic real-game situations in futsal, these findings suggest that superiority in generic motor abilities and anthropometrics may not have a significant effect on performance in futsal matches.</p> </abstract>ARTICLE2022-11-15T00:00:00.000+00:00Associations between device-measured physical activity and balance performance in children: Mediating role of motor self-efficacyhttps://sciendo.com/article/10.2478/bhk-2022-0031<abstract> <title style='display:none'>Abstract</title> <p><italic>Study aim</italic>: To examine the association between accelerometer-measured physical activity (PA) and balance performance among children with considering motor self-efficacy as a mediator.</p> <p><italic>Material and methods</italic>: The present study employed a correlational-comparative approach.

(P &lt; 0.05).</p> <p><italic>Conclusions</italic>: Six weeks of mindfulness and mental skills training can help improve athletic performance by reducing anxiety levels.</p> </abstract>ARTICLE2022-04-10T00:00:00.000+00:00Influence of obesity on spatiotemporal gait parameters among female students from Jouf University, Saudi Arabiahttps://sciendo.com/article/10.2478/bhk-2022-0016<abstract> <title style='display:none'>Abstract</title> <p><italic>Study aim</italic>: The aim of the current study is to explore the effect of obesity on spatiotemporal parameters of gait in obese young female students.</p> <p><italic>Material and methods</italic>: A cross-sectional study with fifteen obese female university students (mean age = 20.3 ± 1.6, mean BMI = 36.2 ± 4.6) and fifteen normal weight female university students (mean age = 20.9 ± 2, mean BMI = 22.6 ± 2.4) was conducted. The spatiotemporal gait parameters were evaluated using GAITRite® walkway (Frankline, USA, Model No. TR30RAM090 with software version 4.89C2).</p> <p><italic>Results</italic>: Independent sample t-test showed statistical significant differences in some spatiotemporal gait parameters between normal and obese subjects with statistically significant reductions of single-limb support time, step length, stride length, and velocity in the obese subjects rather than normal subjects (p = 0.031, 0.015, 0.039, and 0.002, respectively). Moreover, there were statistically significant increases of step time, stride time in the obese subjects rather than the normal subjects (p = 0.038, 0.017, respectively).</p> <p><italic>Conclusion</italic>: These results suggested that obesity is a factor that adversely affects the spatiotemporal gait parameters in the obese young female. This may be contributed to decrease the joints’ mobility and increase the incidence of joint osteoarthritis. So, it is recommended to encourage the sufficient physical activity and weight reduction among obese female students.</p> </abstract>ARTICLE2022-03-16T00:00:00.000+00:00en-us-1
