The diffusion of technology in training and competition is increasing as a matter of course. A great spectrum of technologies are used, from video-information-systems to complex measuring stations, that give athletes and trainers feedback on movement skills. These technologies facilitate learning and optimizing movement skills. If technologies, that are used in training can’t be used in competition (e. g. competition rules, environment), a reduction of performance is possible. It can be assumed that augmented technologically mediated informations used in training enhance performance. But if these informations are lacking (e. g. during competition) athletes can’t reproduce their performance achieved when these information were available.

This reversal effect is described by the guidance hypothesis. This means that the augmented informations guide the learner, becomes part of the movement skill itself and the task-intrinsic feedback will be blocked. When the augmented informations are not available (e. g. competition), an unstable performance is the result, because the athletes can’t compensate the lack of information sources they have gotten accustomed to. The main thesis of the PhD-Project is: Problems in the transfer from training situations to competition situations will be identifiable if technology is used substantially in training, but only on a limited scale or not at all in competition. To affirm the thesis, the PhD-Project will answer the following questions:

• Which technologies are used in training as opposed to competition situations?
• How does the different usage of technology in training and competition influence athletes?
• Do gender differences exist?

For this purpose qualitative interviews, questionnaires and an experiment are conducted for data acquisition.
