Creative motor actions and constraints


The studies linked here provide an insight into the current state of research on the influence of personal and situational factors on creative motor problem solutions. As is so often the case with the topic of creativity in sports games, Daniel Memmert is part of the research team at the Sport University Cologne.

The research goal: „German football players are usually described with adjectives such as disciplined, tactically intelligent, or diligent, whereas the word creative is rather rarely associated in connection with the German sports game.“ Within this project, targeted training concepts are developed to the creativity of sports players to promote.“

The specified further research leads to exciting insights into the emergence of creative movement solutions in sports.

Die hier verlinkten Studien geben einen Einblick in den aktuellen Stand der Forschung  zum Einfluss von persönlichen und situationsbezogenen Faktoren auf kreative motorische Problemlösungen. Zum Forschungsteam an der Sporthochschule Köln gehört wie so oft beim Thema Kreativität in den Sportspielen Daniel Memmert.

Das Forschungsziel: „Deutsche Fußballspieler werden meist mit Adjektiven wie diszipliniert, taktisch intelligent, oder fleißig umschrieben, wohingegen das Wort kreativ eher selten im Zusammenhang mit dem deutschen Sportspiel in Verbindung gebracht wird. Innerhalb dieses Projektes werden gezielte Trainingskonzeptionen entwickelt, um die Kreativität von Sportspielern zu fördern.“

Die angegebenen weiterführenden Forschungsarbeiten führen zu spannenden Einsichten in die Entstehung von kreativen Bewegungslösungen im Sport.


From Inner Coaching to „Coaching in sports“

The Blog now has the title
„Coaching in sports – new ways in learning“. Started with the thoughts and ideas of Timothy Gallwey and others about Inner Game and Inner Coaching the scaffolding of the blog is more. From there, we started thinking outside the box.

We included all aspects with an evidence-based background that deliver a change in coaching in sports („new ways in learning“): constraints led approach, external focus, differential learning, non-linear pedagogy, implicit learning, theory of dynamical systems,….

And it is not at an end.


Comparing dynamical systems concepts and techniques for biomechanical analysis


Traditional biomechanical analyses of human movement are generally derived from linear mathematics. While these methods can be useful in many situations, they do not describe behaviors in human systems that are predominately nonlinear. For this reason, nonlinear analysis methods based on a dynamical systems approach have become more prevalent in recent literature. These analysis techniques have provided new insights into how systems (1) maintain pattern stability, (2) transition into new states, and (3) are governed by short- and long-term (fractal) correlational processes at different spatio-temporal scales. These different aspects of system dynamics are typically investigated using concepts related to variability, stability, complexity, and adaptability. The purpose of this paper is to compare and contrast these different concepts and demonstrate that, although related, these terms represent fundamentally different aspects of system dynamics. In particular, we argue that variability should not uniformly be equated with stability or complexity of movement. In addition, current dynamic stability measures based on nonlinear analysis methods (such as the finite maximal Lyapunov exponent) can reveal local instabilities in movement dynamics, but the degree to which these local instabilities relate to global postural and gait stability and the ability to resist external perturbations remains to be explored. Finally, systematic studies are needed to relate observed reductions in complexity with aging and disease to the adaptive capabilities of the movement system and how complexity changes as a function of different task constraints.
