Direct feedback to athletes in sport increases the efficiency of learning and therefore also the success of training. The most effective way in which this can be done is for immediate, comprehensible movement feedback to be provided in the course of training.


The success of implementing training for specific exercises relies strongly on the participant’s awareness of their body movements. Scientific investigations have shown that direct feedback, just seconds after the execution of a movement, has a positive influence on the learning process. Methods which can be integrated easily into P.E. lessons and training, which give direct feedback to athletes, are therefore a particularly effective resource.



Movement expert Schmidt said that „Motor memory is the product of learning“. We have found that this learning process can be accelerated through the use of sports technology and biofeedback.


Motor learning is the use of strategies to develop and acquire new movements, consolidate familiar ones, or to combine the two (Rieder). It is therefore an active process, in which bodily awareness can be increased by the subject themselves (Neubert et al., 2001). The objective of research therefore has been to reinforce the 'inner perspective’ of the subject (Freynet, 2008). For the coach this means that they simply have to instigate and aid the learning process. Technology can help this process by giving the coach more possibilities for the design and portrayal of movements and therefore the possibility that the athlete might understand a movement pattern better.


Motor learning can be divided into two areas; intrinsic and extrinsic feedback. Intrinsic feedback develops through proprioceptive pathways during movement. Extrinsic feedback however operates via external pathways (Schmidt & Wrisberg, 2008). Schmidt and Wrisberg classify these into Knowledge of Results (KR) and Knowledge of Performance (KP). In KR the athlete receives feedback about the result of the movement but not about how it was executed. KP on the other hand, informs the athlete about the movement quality, giving feedback such as "Your knee is rotating inwards". Biofeedback can be given in the form of both kinematic and kinetic parameters, providing the subject with information about velocity, acceleration, strength and tension. This kind of feedback has been used successfully for several decades now and the research group at Onate verified that faulty movement patterns can be corrected through video feedback in 2005. 

Our software for school and club sports - Simi VidBack

Simi VidBack supports and facilitates the learning and teaching of movement execution, with particular focus on technique, during P.E. lessons or training. The software allows the time-lagged playback of previously recorded movements at any speed to provide the necessary time which the athlete needs for the monitoring of a movement upon completion. The athlete can look at his technique on the monitor and receives a instant feedback about movement execution. Whilst this takes place the next athlete is able to record his own movement, which allows the smooth running of training sessions. In addition to playbacks, video sequences can be saved with one button, even when the action has already taken place. The coach or athlete is able to decide which sequences they would like to analyse.

Sequences which have been saved on Simi Vidback can also be processed and undergo further analysis in other Simi software packages. In addition, there’s the possibility to highlight certain areas of the video with markers, so that the athlete or coach can be given guidelines to aid their understanding during analysis. These new multimedia technologies can now be set up on cheap and easy to use computer and camera systems for sports development programmes, clubs and P.E. lessons.

What makes Simi VidBack unique?

Time consuming video analysis is now a thing of the past! With traditional video systems, recordings have to be stopped for playback, which takes up valuable time. Simi VidBack works entirely automatically, allows smooth training process and demands no interaction from the user whatsoever.

Simi VidBack can save video sequences at the click of a mouse. The editor decides after the recording, whether the corresponding video sequence is to be saved, and can therefore sort video clips with ease.

What is the operational procedure for Simi VidBack?

Simply connect the camera to the computer, open the program and begin the exercise. All athletes can follow up their movement on the monitor directly after its execution.

VidBack setup example

Simi Aktisys not only provides immediate video feedback, but also a number of kinematic measurements. The athlete is immediately informed via audiovisual feedback whether, for example, a certain joint angle in the movement sequence has been achieved. Training can therefore commence and adherence to certain exercises can be identified and highlighted automatically by the system. In addition, Aktisys can play videos and joint angle data at reduced speed. The athlete therefore has access to their exact joint angles so that quantified feedback can be given immediately.
