Gathering Data- Physical Skill

Gathering Data on the Physical Factor

Video Analysis

Describe a method you used to gather data on your performance (4 marks)

In order to use video to gather data on my performance I would go through the following steps:

Video camera/ipad set up at back of court to allow viewer to see the full court.
Performer recorded when playing in a best of 3 match against an opponent of similar ability.
After match the performer can watch the video in slow motion to identify skills that they need to develop.
A coach can record an audio clip over the video and draw arrows annotating o the illustrate key points that the player needs to work on.
Finally the performer can compare their performance side by side to a model performer.

Explain why you used this method to gather data on the Physical Factor (4 marks)

Point>Explanation>Example

Method is Valid: because the video allows you to collect information on how well you performed different skills in a game situation whilst performing under pressure.

Method is Accurate: because the video was set up allowing me to see what position my body was in when playing different shots in Badminton, but also allowed me to see where my shots landed. This allowed me to determine what shots were effective and what ones weren't.

Method is Reliable: as I could watch my performance over and over again, I could pause the video to make notes on anything I observed, then continue watching so I did not miss any of the footage. I could also slow the speed of the video and watch in slow motion. I could also watch my performance on a split scree next to a model performer. These features allowed me to accurately identify what parts of my technique I need to work on.

Permanent Record: I can store the videos on my iPad and after I have been training to improve my technique I can take a new video and compare back to the original video to see if I have improved my technique.

Break down method into different parts> Analyse each part

A performance can be recorded from a number of different angles. This may allow a performer to see exactly what position their body is in when performing a particular skill. For example if a swimmer is performing a dive, a side on angle will show the angle of their body when entering the water. However some angles, such as a staight on angle would make it difficult to determine if the dive has been performed effectively or not.

A video can be caputured while the performer is participating in a match/race. This allows the performer to see exactly how they performed under pressures and means that they can use this information to plan an appropriate development programme.

The performer can analyse the video with a coach. Making use of the coaches expertise should allow the performer to accurately identify any flaws with their technique. For example the player and coach can discuss the performance and agree what the player needs to work on.

The slow motion button can help to ensure the player and coach make accurate judgements. The performance can be watched over and over in slow motion allowing for in-depth analysis of a players technique. If a video is analyses at 'match speed' this could mean something is missed because of the fast pace of the game.

The video can be kept as a permanent record. This means that a performer can refer back to this during the course of a development programme and see if their performance has improved.

Model Answer:

The benefits of using video is that once I have videoed my performance then I am able to view and analyse my performance and this can help me to see what improvements I need to make which was good as it helped to improve certain areas of my technique. Another advantage is that the video can be viewed at any time and can also be re-winded, fast forwarded or slowed down which was useful as it meant I could view my technique a lot and in slow motion which would give me a better view. The limitations of video is that it can require a lot of money to first set up which meant that I would have to take up some time and make some purchases. Another limitation is that it could take a long time to do if there is a lot of people that need videoed so it can limit training time.

The benefits of a scattergraph is that it is easy and simple to understand so it can easily be executed and carried out. Another benefit is that it provides valuable and valid information that can then be referred back to in the future. A limitation of the scattergraph is that if the shot is high paced it might be hard to see exactly where it lands so it may not be as accurate.

Evaluate your results in comparison to a Model Performer (4 marks)

Point >Evaluative Judgement>Example

My overhead clear technique is similar to that of a model performer. I know this because when I perform this shot I can see that the shuttle consistently reachers the back tramlines. I make minimal errors when playing this shot.

My low serve is not nearly as good as a model performer's. When I play this shot the shuttle goes much higher over the net and on a number of occasions my opponent returned my serve with a smash that put me under pressure. These errors cost me a number of crucial points.

My smash is also not nearly as good as a model performer's. A model performer can generate significantly more power in their smash than I can. This makes it more difficult for an opponent to return the shot as they have less time to react to it.

My drop shot is a strength. I make few errors playing this shot and have a high level of accuracy meaning the shuttle just goes over the net and lands close to the front of court. This is similar to a model performer who would also make few errors when using this shot.
