Start now….

These are strange times… No teamsport, no activities in the sportscentre and in your sportsclub. Thats why there are less posts in my inner coaching blog in the moment.

There are some physical activities and only a few sports we can play in these corona pandemie and in the shutdown. But this has not so much to do with Inner coaching in sports, because the goal, when we spend most of our time at home, is to move. We don’t think about the best methods to develop technical and tactical skills. (May be this is the time to recover a street culture, where we use the urban space for free playing without instruction and recovering creativity).

One sport we can play in the crisis is the new sport from Switzerland: Street Racket. You find a lot of information, videos on the homepage of my TMS Tennis School and on Street Racket Switzerland. This game can be played in the smallest area, in hundred of variations. Have a look and play.

We are back soon!

Zeit zum Lesen…

Die Zeiten zwingen uns zum Innehalten. Der Virus gibt uns (zumindest den Coaches) Zeit zum Nachdenken, Lesen und Weiterbilden.

Wer mehr über Differenzielles Lernen im Tennis und Neue Wege des Trainings wissen möchte, dem empfehle ich meine Artikel in der Zeitschrift TennisSport. Hier ein Beispiel.

Über Linkedin oder über die Suchenfunktion in diesem Blog findest Du außerdem zahlreiche Artikel zum motorischen Lernen, zum Kindertraining, zur Mitbestimmung im Verein und mehr. („TennisSport“)

Bei Rückfragen stehe ich gerne zur Verfügung. Schick einfach eine Mail an

Neue Bedingungen – Kreative Lösungen from Frercks Hartwig

Differenzielles Lernen im Tennistraining

Coach the coach ist eine kollegiale Weiterbildung in der Tennisschule TMS. In der letzten Veranstaltung am 1. März 2020 ging es unter anderem auch um das differenzielle Lernen im Tennistraining. Vorgestellt wurde es von TMS Coach Frercks Hartwig.

Weitere Themen des Treffens:

Street Racket, Trainingsentwicklung mit der Bank, Trainingsformen zur Verbesserung von Beinarbeit, Laufwegen und Kondition.

Street Racket

A game to revitalize street game culture. Without skill and tactical instruction, cooperative and without pressure to win. Self-determined game with little material. This new Swiss trend sport offers everything that is described on this blog as a prerequisite for motor learning.
For schools, for clubs, for breaks with (e-)motion

anyone – anytime – anywhere

Let’s rock the streets…


Constraints led or is there more? Back to the question.

Can we say, that the sportive action in this picture shows elements of differencial learning in tennis? Constraints change seeing, hearing, time, speed, field size, target, emotion,…

(Thx Mark O Sullivan for the picture, Mark is doing a wonderful job at AIK Stockholm and is writing about constraints led coaching, childrens rights in sports and more on the blog „Player development project„)

Wolfgang Schöllhorn, who has thought and researched about the best way of learning skills in sports, is helping me to understand the differences between Differential learning (DL) and the Constraints Led Approach (CLA) fixing one’s eye on the picture above.

„This is a nice example for explaining the difference of constraints led approach and differencial learning 😉 . Here you see extraordinary constraints in order to feel what you should not do in future (variant of contrast learning). But this only would become differencial learning if the boundary conditions would change next time, e.g. if the „other side“ would change the flying objects (size or speed) or if this guy would change his glasses, the mask, the racket, the technique, the target … next time. In differencial learning it is rather about the rate of change of boundary conditions, it is less about the stressful constraining situations that should be avoided next time. ;- ) “

from a facebook discussion

Constraints or should we…

find another word to describe what we do in our exercises in tennis? I think, that the way of differential learning (DL) is a better way for learners and players to develop technique and tactics in a sport like tennis. Still tennis coaching is dominated by methodical traditionalism and explicit learning.

Wolfgang Schöllhorn, scientist at Johannes-Gutenberg-University at Mainz, after long research about motor learning, has written an nice article about the history of nonlinear pedagogy und the constraints led approach (CLA). And why they are different to DL.

In this blog I use nonlinear pedagogy and CLA very often. They are following systemic theory and implicit learning. Making this real on courts, would be a milestone. But Schöllhorn has researched about motor learning and discovered, that there is a more effectiv way to learn. He called this Differential Learning (DL). In this article from 2019 he describes, why CLA is still dominated by the idea of leading the learner and that the coaches goal is still to bring him to a nonautonomous goal.

I think, Schöllhorn is right. This means in consequence: I have to overthink the terms I use to describe what my players do in trainings. Constraints can be understood as a term for changing courtsize, material, partners, tasks, emotions,…. but not from a pedagogical view and in distinction to CLA.

Constraints and Differential learning, some keys

ask for feedback

be patient

create a level of instability

don’t talk too much – concentration is silent

explicit coaching leads to breakdown under pressure

freedom to create

give back autonomy to the athlete

human systems theory

implicit coaching improves problem solving and decision making

kill, no, don’t kill creativity by setting clear textbook structures

Ein Appetizer

Die Vorträge beim Bayrischen Tennisverband (BTV) und beim Württembergischen Tennisbund (WTB) über „Neue Wege im Tennistraining – vom Inner Game zum Differenziellen Lernen“ hatten immer etwas Gutes: das Feedback der Teilnehmer*innen, jeweils C/B-Trainer*innen bei der Trainer*innenfortbildung des Verbandes.

Die Reaktionen reichen von ungläubigem Staunen über heftige Kritik bis zu heller Begeisterung und Zustimmung.

Ich habe mich nun entschlossen, den Vortrag in ein Video zu packen, da das Thema aktueller denn je ist und es höchste Zeit ist, dass die wissenschaftlichen Erkenntnisse zum motorischen Lernen auch bei den Tennistrainer*innen und an der Basis ankommen. Leider lässt sich im Tennistraining noch viel zu häufig der alte „methodische Traditionalismus“ mit einer starken Technikorientierung vor spielerischem und selbstbestimmten Lernen beobachten.

Der Vortrag und die im Schnellverfahren beschriebenen „Neuen Wege“, die manchmal schon ältere, aber nicht wertgeschätzte Trainingsmethoden sind, sollen Kolleg*innen anregen, ausgetretene Pfade zu verlassen und Wege zu gehen, die auch ihnen die Arbeit in einem immer komplexer werdenden Bereich erleichtern können.

Das komplette Video soll bis Ende Januar veröffentlicht werden. Solange empfehle ich Euch diesen Blog und den Inner Coaching Kanal auf youtube.
