The athlete\u2019s body is a black box, thousands of chemical, electrical and mechanical processes are going on and we don\u2019t have a clue what we are doing here. Yes, if you train, something changes, the body adapts. But\u00a0 what, where, when and why? No idea!\u00a0 Instead of endless tinkering and \u201ctrial-and-error\u201d, in an early stage of my career as a coach I thought it more efficient and useful if\u00a0 I at least gave it a try to understand the most relevant on going processes. This way at least my stumbling in the dark got some direction.<\/p>\n

The second idea was that most of training is the training of the brain and the nervous systems, not exclusively of course, but being more important than we always assumed.
\nAt that time very little attention was given to this idea, even sports psychology was of little help here. And even today the brain is a strange organ to work with. The psychiatrist is probably the only medical professional not having a proper diagnosis of the organ he\/she tries to change or improve before intervention takes place.
\nOf course, as a coach we often only look at observable or measurable behaviour of athletes, in training and in competition, that is: do athletes perform as we expect or as we want them to?
\nOne of the first projects I started was to look at the brain, more specificly at brain laterality, the different functionings of the left and\/or the right brain and the preferred use of one of these sides of the brain. In 1994 I was part of research group in Oslo Norway, doing biomechanical research on sprinters. With this group I performed a short EEG (brainwave) test: 2 minutes eyes open – 2 minutes eyes closed- 2 minutes eyes open. And also looked at handedness, footedness and the dominant eye of these athletes and a laterality questionnaire, consisting of 40 MC questions to establish brain dominance. Interesting!
\nI also bought my own portable EEG measurement equipment and I even was able to measure EEG, brain dominance 30 minutes for a World Championships final race in sprints.<\/p>\n

\"EEG<\/a><\/p>\n

Also I tested more static sports like archery (less movements artefacts and mainly a mental sport), golf and shooting.<\/p>\n

\"EEG<\/a>

I started to use EMG of electromyography to measure muscular activity during exercise and training. This is still the only practical and reliable way to see what, when and in what order muscle groups work during movement.<\/p>\n

\"Telemetric<\/a>

This separates facts from fiction, since many coaches make bold statements on how and which muscle works e.g. during sprints or during weight exercises e.g. recruitment of fast vs. slow muscle fibres. And Henk\u2019s second rule applies: \u201cthe less knowledge somebody has about a subject, the bolder the statements about the subject are\u201d.
\nI have heard and read the most ridiculous statements which display a lack of deep knowledge about these subjects. Like a mentor of mine used to say: \u201cIn god we trust, all others show data….\u201d.
\nWhat surprises me is that over the past decades professional coaches and therapists are not using EEG or EMG measurements more or using these tools for intervention such as neurofeedback or EMG biofeedback. This to teach athletes awareness and self-regulation,\u00a0 which most professionals will agree, are important. And like a very smart person once stated: \u201cwhat you cannot measure, you cannot improve\u201d. I do not agree for the 100% with this statement since \u201ctrial-and-error\u201d can go\u00a0 a long way sometimes. And collecting tons of data, which is easy these days, isn\u2019t going to solve this problem if you do not know what is relevant and significant. And if you don\u2019t know how the interpret the data and make the very important link with possible interventions, you\u2019re stuck as well.<\/p>\n

I am using psychophysiology and biofeedback since the end of the 1980\u2019s but still very few of my colleagues are using EEG or EMG or biofeedback in general.
\nWhat could be the reason for that?
\nSome ideas on why this is:
\n– they are not familiar with psychophysiology or biofeedback
\n– these subjects demand a certain basic knowledge of physiology, anatomy and technology
\n– it can only be done with specific equipment
\n– it is always on an individual basis, so rather time-consuming if you coach large groups.
\nOn the other hand: coaches should never be afraid to improve their knowledge and you don\u2019t have to be a neurosurgeon to work with this equipment.\u00a0 For the price of a treadmill or exercise bicycle, you can have the Rolls-Royce of psychophysiology equipment. And the time-problem is a matter of planning and priorities and it is time well-spend.<\/p>\n

Biofeedback and psychophysiology: just go out and have a look…..<\/p>\n
