The advent of digital video has meant that it is easy to capture sports action during training, and feed back to the athletes. How this is done depends very much on the type of sport (see BrianMac's website for a good description of the differences):

Open Sports Skills

Much of the action in sports such as football or tennis depends on rapidly changing situations, where you must learn how to position yourself, and perhaps your team-mates. For these situations the coach can video a practice session or sequence, and then use one of the many free or commercial video analysis tools to draw lines, move to key movements, etc. You will often seen this on Match of the Day in the UK, or your local sports program.

Normal speed video taken from a single 'overview' angle works well for this, and feedback can be made during the training session, allowing for practice and repeat.

Closed Sports Skills (Continuous)

In sports such as running or swimming, an action is repeated many times, against challenges which come from speed, fatigue and the limits of the muscles' strength. By its nature, the action is rapid and hard to understand, and it can be difficult for the sportsman to consciously change his action without throwing the whole pattern out.

This is where we can help: In these situations, slow motion video, preferably taken from different angles, really helps. Even for the beginner, it may not be possible (or even advisable) to modify the action directly, but the physio or coach can study the video to identify treatment or devise specific exercises, conditioning, drills and stretching.

Closed Sports Skills (Discrete)

Sprints starts, tennis serves and football penalties are all fast actions, which must be practiced repeatedly. For the beginner, normal speed video from a single angle is usually sufficient to give live feedback. For the advanced performer, slow motion multi-view video may be needed for the coach to understand the nuances of movement, and devise an appropriate training programme.
