Kracht van Aangepaste Sport

Voor u ligt het derde boekje dat wij uitgeven naar aanleiding van de lezingenreeks ‘Kracht van Sport’. Het betreft de vijfde maal dat wij de reeks organiseren. De reeks startte in 2012 met het onderwerp; ‘Olympische Spelen in Nederland: Droom of Nachtmerrie?’, in 2013 gevolgd door ‘Kracht van Sport’ (boekje), in 2014 ‘Kracht van Sport: over de grens’, in 2015 ‘Kracht van Sport: de verbinding’ (boekje), en afgelopen voorjaar (2016) ‘Kracht van Aangepaste Sport’.

Kracht van Aangepaste Sport

Voor u ligt het derde boekje dat wij uitgeven naar aanleiding van de lezingenreeks ‘Kracht van Sport’. Het betreft de vijfde maal dat wij de reeks organiseren. De reeks startte in 2012 met het onderwerp; ‘Olympische Spelen in Nederland: Droom of Nachtmerrie?’, in 2013 gevolgd door ‘Kracht van Sport’ (boekje), in 2014 ‘Kracht van Sport: over de grens’, in 2015 ‘Kracht van Sport: de verbinding’ (boekje), en afgelopen voorjaar (2016) ‘Kracht van Aangepaste Sport’. Tijdens deze lezingenreeks komen verschillende doelgroepen binnen de aangepaste sport naar voren, deze onderwerpen zijn vastgesteld samen met vertegenwoordigers uit de revalidatie, geneeskunde en sport. De onderwerpen die aan bod komen zijn sporten met: niet-aangeboren hersenletsel, een gedragsstoornis, een lichamelijke beperking, een verstandelijke beperking, een visuele beperking en een auditieve beperking.

Exploring and exploiting and why we always end up with the Beatles

It is argued that pop music has long been locked up in the exploitation phase. Boring, more boring and even more boring seems to be the motto, and only extreme, as now boring monotonous hip hop from Chicago / London - called drill - in which "respect" is enforced by the real killing in quarrels between rival gangs, explores the border. For the rest, contemporary pop music is exploitation, until we learn to listen differently to the many talents that remain undiminished and we grant them the adventure of musical or scientific exploration.

An Exploratory Meta-Analytic Review on the Empirical Evidence of Differential Learning as an Enhanced Motor Learning Method

Background: Differential learning (DL) is a motor learning method characterized by high amounts of variability during practice and is claimed to provide the learner with a higher learning rate than other methods. However, some controversy surrounds DL theory, and to date, no overview exists that compares the effects of DL to other motor learning methods.Objective: To evaluate the effectiveness of DL in comparison to other motor learning methods in the acquisition and retention phase.Design: Systematic review and exploratory meta-analysis.Methods: PubMed (MEDLINE), Web of Science, and Google Scholar were searched until February 3, 2020. To be included, (1) studies had to be experiments where the DL group was compared to a control group engaged in a different motor learning method (lack of practice was not eligible), (2) studies had to describe the effects on one or more measures of performance in a skill or movement task, and (3) the study report had to be published as a full paper in a journal or as a book chapter.Results: Twenty-seven studies encompassing 31 experiments were included. Overall heterogeneity for the acquisition phase (post-pre; I2 = 77%) as well as for the retention phase (retention-pre; I2 = 79%) was large, and risk of bias was high. The meta-analysis showed an overall small effect size of 0.26 [0.10, 0.42] in the acquisition phase for participants in the DL group compared to other motor learning methods. In the retention phase, an overall medium effect size of 0.61 [0.30, 0.91] was observed for participants in the DL group compared to other motor learning methods.Discussion/Conclusion: Given the large amount of heterogeneity, limited number of studies, low sample sizes, low statistical power, possible publication bias, and high risk of bias in general, inferences about the effectiveness of DL would be premature. Even though DL shows potential to result in greater average improvements between pre- and post/retention test compared to non-variability-based motor learning methods, more high-quality research is needed before issuing such a statement. For robust comparisons on the relative effectiveness of DL to different variability-based motor learning methods, scarce and inconclusive evidence was found.

Quantifying postural control during exergaming using multivariate whole-body movement data

Background Exergames are becoming an increasingly popular tool for training balance ability, thereby preventing falls in older adults. Automatic, real time, assessment of the user's balance control offers opportunities in terms of providing targeted feedback and dynamically adjusting the gameplay to the individual user, yet algorithms for quantification of balance control remain to be developed. The aim of the present study was to identify movement patterns, and variability therein, of young and older adults playing a custom-made weight-shifting (ice-skating) exergame. Methods Twenty older adults and twenty young adults played a weight-shifting exergame under five conditions of varying complexity, while multi-segmental whole-body movement data were captured using Kinect. Movement coordination patterns expressed during gameplay were identified using Self Organizing Maps (SOM), an artificial neural network, and variability in these patterns was quantified by computing Total Trajectory Variability (TTvar). Additionally a k Nearest Neighbor (kNN) classifier was trained to discriminate between young and older adults based on the SOM features. Results Results showed that TTvar was significantly higher in older adults than in young adults, when playing the exergame under complex task conditions. The kNN classifier showed a classification accuracy of 65.8%.Conclusions Older adults display more variable sway behavior than young adults, when playing the exergame under complex task conditions. The SOM features characterizing movement patterns expressed during exergaming allow for discriminating between young and older adults with limited accuracy. Our findings contribute to the development of algorithms for quantification of balance ability during home-based exergaming for balance training. Copyright:
