Video analysis - also referred to as "outside perspective" or "third eye" - is used in physical education with the aim of analyzing students' movement techniques, among other things. For this purpose, the teacher provides individual feedback. With the help of video analysis in physical education, movement corrections can be clearly communicated.
Goal and functions of video analysis
The goal of video analysis can be optimally illustrated using a wide variety of sports as well as with the help of professional sports (e.g., competitive soccer): It has already been used in this area for a long time, for example, to be able to repeatedly view movements - running routes or similar - in slow motion. But video analysis can also serve the purpose of promoting young talent.
The ultimate goal is to analyze and improve individual performance by visualizing and viewing one's own movement. Thus, the importance of video analysis in physical education has now also increased in recent years.
The video analysis uses certain functions such as video overlay, slow motion function, the synchronous display of multiple videos and angle measurements. In the video itself, markers can additionally be set to be able to retrieve them even if they are opened again in the future.
Advantages of the use...
The advantages that result from the use of video analysis in physical education are numerous: For example, learning performance and for example, learning performance and training success increase. training success when video feedback is used immediately after movement execution. In addition, incorrect movement patterns are corrected.
However, the use of video analysis during physical education is also useful from a didactic point of view: Video analysis visualizes movement images objectively, analyzes and documents movement quality. This is a useful alternative to the teacher's purely verbal and abstract description, which is often not sufficiently understood by students.
The video analysis can also show movements from different perspectives. and better capture them using a repeat and slow motion function.
Furthermore, it is difficult for the student to understand exactly which errors the teacher has observed, since these are not visually documented, but merely described. With the help of a video recording, however, individual errors can be better traced.
...in physical education classes during exam situations....
Another situation that can be optimized with the use of a video analysis tool is the examination situation: A performance is usually assessed in physical education classes by students performing various exercises or sequences of movements. But also games, choreographies or other performances are evaluated by the teacher with a grade.
However, it is difficult to objectively evaluate such a performance when the exercise or game lasts only a few minutes.
In addition, students are in an extreme stress situation during the exam situation. This can significantly reduce performance. With the help of a so-called video performance review , students can present a video of their own choice - selected from all recorded videos - at the end of the lesson. The assessment is then based on the video recording on the tablet or laptop.
...or in other school subjects
With the help of tablets or laptops and their large screens, video analysis can now also be used in numerous school subjects, for example in experiments - but especially in sports lessons. In addition, the quality of the video analysis tools has increased: This means that even complicated movements can be captured and analyzed.
Video analysis, which can be used in all school levels - regardless of lower or upper school - makes training more efficient, athletic performance is optimized, and objective feedback is facilitated by direct control of training success.
Challenges in the use of video analysis
In addition to the numerous advantages offered by video analysis in physical education, there are also some challenges or factors that need to be taken into account: For example, possible interference from objects and inaccuracies should be avoided. In addition, for data protection reasons, it is necessary for teachers to ask students for their consent regarding the recordings. Finally, videos should only be used for the purpose of analysis and coaching and should be deleted immediately after the lesson.
Areas of application of video analysis
- Pole Vault
- Long jump
- Fußball, Handball, Volleyball
- Slingshot ball
- Hammer throw
- Discus throw
- Ski Jumping
- High Diving
- Swimming lessons
In addition to the feedback and analysis functions, it is also useful in school sports to create guide pictures for students with the help of video recordings. In concrete terms, this means that correctly executed exercises are visualized and made tangible for the students by means of image series. The correctly executed movement (e.g. the volleyball serve) is extracted from a video and then exported as an image series.
This enables students to learn fast movements in particular more efficiently. To reinforce what has been learned, the teacher can subsequently instruct the student to practice this movement at home with the help of the illustrated instructions.
Furthermore, video analysis systems can also be used for recording physics and chemistry experiments independently of their use in physical education classes.
Beginner-friendly software for video analysis in sports lessons
There are many different ways to technically implement video analysis. For example, there are complex video analysis systems with several fixed cameras. cameras. However, these are usually oversized for teaching purposes. The task here is to find a simple, easy-to-use solution.
An example of suitable software is utilius fairplay 5. The sports software is particularly suitable for beginners due to its ease of use and user-friendly structure.
The Time Shift and Video Delay functions
With the help of the sports software utilius fairplay, one or two videos can be loaded into the software, where they can be displayed directly next to or on top of each other.
A video can be played in Slow Motion, which means that the trainer or teacher sees every detail. Very slow fast forward, frame by frame, is also possible.
Furthermore, individual scenes in the video can be marked - "tagged". Annotations can then be written and the scenes can be played back or exported individually.
The Time Shift mode (Video Delay) also enables video feedback. Time shift means that the content of a video can be recorded simultaneously and played back with a time delay. In this case, a motion execution is recorded normally, but the playback on the screen takes place a little later. The time shift should be chosen in such a way that the student has enough time to get to the monitor after the execution. This means that a video can be viewed while it is being recorded and does not have to be paused or rewound.
The use of video analysis systems is not only useful in competitive sports, but also in schools, and offers both students and teachers suitable support.
