Known and new things

Depending on the knowledge of each reader, some may discover new things, while others may rediscover things once known. Unfortunately, some “boredom” cannot be avoided, due to the many different levels of knowledge of the individual readers. The goal of this blog for the next weeks is to create a kind of a basic understanding […]

Examples to get you started, Part I

Martial arts have a strong attraction through a variety of performances in movies and literature. Some of the performance seems superhuman. Following , a few examples for an introduction. In the first example, an approach is explained in a fight. This is discussed extensively in the text as a whole in dealing with forces and […]

Examples to get you started, Part II

There are impressive examples for sure, but many less impressive examples are also out there. The following video is from the movie Zatoichi – The Blind Swordsman [3]. In this scene, the character tries to give a little lesson. Many fundamental problems in martial arts are already displayed, which doom the instruction to failure. No […]

Book Review, Part 1

The German version of this blog has a short review of the German book „Bewegungswissenschaft. Ein Lehrbuch in 12 Lektionen“ [1] (Motor Control. A textbook with 12 lessons.). I’m not familiar with the English literature regarding a book on motor control that gives such a short but extensive overview. Proposals for such books in English […]

Characteristic Problems, Part 1

Motor Control might appear very dull in its depiction in books. Experimental subjects boringly move levers back and forth and the examiner is “delighted” during evaluation when the raw data of muscle activation changes during the tests (at least some kinds of texts make it appear this way). Despite its direct relevance to martial arts, […]

Characteristic Problems, Part 2

In a second example, the potential of a feint shall be examined a bit. The attack should simulate a feint in the form of a lower kick just above the belt line. After the bluff, the kick should be swung to the head of the opponent. The goal of the feint is to get the […]

Characteristic Problems, Part 3

The third example presents an attempted kick defense as a reaction. The attack is a slightly deeper side kick to the thigh. Here, your own leg is raised, exposing only the shin as a hit area. This example only serves as a brief introduction to illustrate several problems. Actually, you would have to decide on […]

Characteristic Problems, Part 4

Some of the briefly discussed problems entail follow-up difficulties. These are not always directly observable. The blog is mainly about motor control, but in this example, the result of not properly designed movements is discussed. The problems presented thus far tend to frustrate you. Nevertheless, the frustration can be transferred into training if the problems […]

Effects and Models

I hope that the first examples have aroused your interest. Unfortunately, I have to interrupt things at this point. Motor Control is an area of constant change. It is important to differentiate between effects and the underlying models. You can rely on effects. They can be repeated and can be used for simple derivations similar […]

Daily Failures, Part 1

You take movement failures for granted in your life. If you fail to grab a bottle, then you try again. If you stumble, then your body will rebalance you. The big number of mistakes and their continuous appearance leave you dulled. It becomes quite normal to just accept these things. The distinction between “everything is […]

Daily Failures, Part 2

The following examples concentrate on daily failures with a focus on biomechanical aspects and reflexes. These aspects are vital to improve movements in view of e.g. force, momentum or speed. There is a very good book on biomechanics. “Biomechanics of Sport and Exercise” from Peter M. McGinnis (Link), which gives a very good introduction to […]

Daily Failures, Part 3

The following daily failures address internal models, how rhythms are set and how this process fails due to certain boundary conditions. It is important that internal models are based on all available information. These include rules, goals and knowledge of cause and effect. It is a common error to exclude or not consider certain pieces […]

Daily Failures, Part 4

The latest blog entries on daily failures focused a bit on reaction times, rhythms and biomechanical aspects. This entry deals with other biomechanical aspects and the kind of information that can be derived from simple conclusions. Again, the idea is to retrieve as much information as possible to successfully “model” an opponent’s intentions. The blog […]

Daily Failures, Part 5

One can compile long lists of basic motor control problems in martial arts and still, wrong internal models and their underlying reasons will always be on top of it. It seems that the human body is not meant to live and cope with an ever-changing environment that alters its state too fast. Martial arts have […]

Transmissions in daily life, Part 1

The blog entry “Daily failures, part five” presented a transmission and an example for its usage. If you take a closer look, you will notice that transmissions are nothing special in your daily life. Basically, every human movement consists of several combined transmissions. Remember, a transmission is just translating one movement form into another form, […]
