Critique of Article from The International Journal of Performance Analysis

A Critique of Journal Article from The International Journal of Performance Analysis in Sport
Bampouras T, Cronin C, Miller P (2012) “Performance analytic processes in elite sport practice: An exploratory investigation of the perspectives of a sport scientist, coach and athlete”, from The International Journal of Performance Analysis in Sport. Vol 12 468-483.

This Journal article provided an interesting perspective as to the field use and implementation of performance analysis. The five identified uses of performance analysis were;
a)             To provide immediate feedback
b)            For data base development
c)             To identify areas for improvement
d)            To evaluate specifics of performance
e)             And as a selection tool to assist coaches and athletes.
The first four I have considered in my coaching, however the final one – as a selection mechanism is not currently relevant to my coaching role.

Bampourus et al (2012, p.469), quotes Bartlett (2001, p125), who states that performance analysis needs to  “…provide coaches with information that adds to what they can not see for themselves.” Although a common sense statement, it does highlight the importance of evaluating each technology and ensuring that the process does add value to the feedback provided.

In terms of my own context, there is value in video analysis as the slow motion provides immediate feedback that can help to identify flaws in technique and be used to enhance the understanding of the athlete. Specific technical information that is often missed can be easily highlighted. In Equestrian sports,  unless the rider or coach organizes it, it would be rare that competitions or training sessions are recorded (as with other professional team sports) so visual feedback is not often used.

 I can also see benefit in creating a database to show the progression of both the horse and rider. I have attempted to keep a video log of training progress in the past, however the footage became difficult to access as technology was becoming outdated so rapidly.  With new coaching technology now offering online storage, this is something I will revisit. I am always exciting at how much improvement I see when reviewing old footage and found it provides motivation at times when I feel little progress is being made.

One way that I have not use performance analysis in the past that may be useful is to video the warm-up of my students. Usually due to resource restrictions, only the test is videoed. This is definitely something I will consider in the future as a feedback tool for athletes.

Effective Use of Performance Analysis
Performance analysis application which has been shown to influence coaching practice and athlete development include:
  •  time motion analysis
  •   investigation of play and scoring patters
  •   physiological responses and demands
  •    behavioral studies, (Bampourus, 2012)

Many of the studies referred to in this article were related to the gathering of information via statistics. While I see benefit in this with team sports, currently such data is not used in my sport. Perhaps a catalogue/data base of each component of the dressage test could be created to observe the judge’s perspective and feedback.  This could then be  used as an education tool for the athlete who could develop their understanding by critique others.

The Consensus Model
Bampourous et al., (2012) cites Hughes (2004) who stated the importance of collaboration collaboration between the coach and athletes in order to achieve success.

The authors represented their findings as a “Consensus Model” of performance analysis. In this process the coach and sports scientist work together to select which information is filtered through to the athlete. This highlighted that the athlete’s often had limited input into what data was collected on them and which feedback they received. Athlete’s raised concerns that they were “never given option to say (whether) you want to do it or not, (or) how do you think it is going? Is it beneficial towards us or not? We were never given that kind of control,” Bampourus et al (2012, p478).

The author then raises the question whether or not this is an effective strategy? Concern is raised that excluding the athlete from this process misses important opportunities for development. The coach justifies this process by taking the stance that he is protecting the self-esteem of the athlete. “If you were getting all this information and all this negative information, I think it has to be in stages” describing the coach as a “gate keeping” role, Bamporous et al (2012, p474).

The  author highlights the dilemma - if the athlete is excluded from the process then they are loosing the opportunity to acquire pertinent skills to engage in the process and excluding further development. He argues, “the assumption of incapacity rarely expiates multifaceted skill development,” Bampourus (2012).

I agree with Bampourus (2012, p478) who suggests that “empowerment of athletes through their inclusion in decision – making activities can have a positive performance – function outcome”, and that “self actualization is seldom achieved by those who have little choice but to rely on external regulation”.

I have observed that when I show my athletes footage of their performance, they often identify and place priority on technical flaws, and that their priorities often differ to my own. Although I must question whether their knowledge is sufficient to prioritize such corrections, I also realize that they will have higher motivation to tend to those corrections and a learning opportunity arises if success is not obtained. This further engages and develops the athlete as a learner. Such a process approaches the athlete in terms of long term development opposed to what Bampourous (2012) identifies as “short-term thinking leading to short-term action”.

Other Issues Raised
The study raised several issues in the use of performance analysis. Firstly, that coaches felt it was difficult to access the current research/literature if you are not at University. Subscribing to journals, attending conferences and seminars and making use of the internet coupled with a lifelong approach to learning should enable me to maintain current knowledge and continually strive to implement  best practice.

The other was that may sports do not have access to a sports scientist and that it is very difficult for the coach to maintain their coaching role and supervise the sports scientist or data collection during a competition.  Such a problem is relevant to my sport, however luckily performances only last for 5 to 8 minutes, so organizing a friend to video should be possible. With the computer programs available, it should also be possible to code each movement for later use.

This article highlighted for me the myriad of opportunities available to integrate performance analysis into my coaching and I look forward to developing and implementing these in the future. However, the highlight for me was the opportunity it offers to empower the athlete to take responsibility for their learning and decide which feedback they desire and feel is of most use to  them. As a coach looking to develop my skills in creating an athlete-centered approach , this will be particularly useful.

Video Modeling
The human brain is truly fascinating! I am blown away by the results that I have obtained with my athlete’s this week as I have implemented the video modeling procedure recommended by Boyer et. al (2009). This article found that there were mean increases from the baseline of gymnast’s skills of 53% after the video modeling procedure.

They used the following method:
1 – Video the skill
2 – The athlete views the expert and is asked to “match their performance with the expert” (on the left of the screen)
3 – The athlete views their own performance (on the right screen)
4 – The gymnast news the clips side by side with freeze-framed clips at five different spots.
5 – The athlete views the expert again at normal speed.
6 – The athlete watches themselves again at normal speed.
7 – The athlete attempts the skill two more times.

I used this with my athlete’s and the results were generally remarkable. What I discovered was that you have to make sure that you have the expert performing in the same direction as your video of the athlete. In horses this is called left rein (anti-clockwise) and right rein (clockwise). 

Another interesting observation was that if you do the video modeling in canter left – the athlete can easily copy the expert,  however, they do not seem to be able to transfer it to the right.

Eventually I would like to have a catalogue of different body types of expert riders. Often I noticed that the average rider does not relate to the footage of a rider with a very different body type to them.

This activity really highlighted to me the power of the visual image and how sometimes the fewer words the better! 

One thing I will explore is the results obtained from having the expert footage on the left, rather than the right (as I have done).

Voice Thread....
This week I have spent time planning the set up of my voice thread. I am examining the use of ipad video analysis apps for coaches. The 20-second limit on the voice over per slide forced me to examine voice my communication skills, particularly my ability to be succinct when communicating verbally. I think it is something that I could improve on and this has been highlighted to me by using the coach’s eye app to provide effective feedback to my athlete. 

Another interesting thought about the use of video feedback was whether or not I should comment first or show the athlete the raw footage prior to commenting. One example occured last last Saturday when I allowed the athlete to look at the footage first. She glared at if and stated – “I hate my elbows they stick out too far much" (something I had attempted to address many time before). I then provided my feedback and her performance notably improved. I asked her what she had been thinking about to make such a dramatic improvement – she said “my elbows”, (which was nothing to do with the feedback I had provided). 

Today I saw her again and her technique was better. I commented and she said – “ I have just focused on my elbows all week,”  (of course I had completely forgotten about how important this was to her the previous week.). This event highlighted the improvements that the athlete is able to make when they are motivated to improve and how video feedback is able to provide such motivation.

Review of Journal Article

Today while trying to find a relevant Journal article for my  review, I came across the article Learning with Multimedia – Concepts and Experiences by Joset Wiemeyer.

Wiemeyer (2000) recognized that research indicated, “Students prefer variable, flexible educational methods being applied by highly motivated and motivating teachers.” This point was of interest to me as I do recognize that at times my coaching can become a little like my Mum’ meal selection when we were kids – she would find a meal everyone said they liked and then served it to us everyday for two weeks!! I am going to strive to ensure that I use multimedia as just other tool, rather than a sole means for enhancing performance. 

This article also acknowledges “only subjects with previous knowledge could profit by control over the system”.  This supports my observations from last week.  I was coaching an amateur adult who looked at me blankly when asked to review his performance.  At that point I acknowledged that I had not considered whether or not video feedback was appropriate in all contexts and thought more about integrating its use in appropriate situations.

The author stated that he supported Haggerty’s (2000) “cautious optimism” when using multi media as an educational tool and raised the point that it did require an understanding of many disciplines in order to be used effectively, including “computer technology, psychology and pedagogy. We need to know the hardware and software constraints of multimedia implications for perceptions, learning and memory and influence on culture and education,” Wiemeyer, 2000.

Although this article raised several interesting points and answered some of my questions, I did not understand some aspects of the design and development sections so opted for another article as the one to evaluate in more detail as part of the compulsory requirements of my blog.

Task 1

Well, this week I have had a few technological hiccups. I had nearly finished my PowerPoint presentation and then the slides all went blank. I sought assistance from two Technology Teacher's at work and one suggested that I use keynote instead (as I had managed to crash PowerPoint). So, I had a play around with keynote, however I found it more difficult to use and when I tried to add voice over to a single slide – I could not work it out at all and the online forums suggested it was not able to be done. So, I restarted my computer and thank goodness my presentation restored itself. So, for now I am sticking with PowerPoint.

My second hiccup was trying to get a computer to run Dartfish and Visual Coach.  The IT people at work warned against installing a converter on the Mac as they said it would run very slowly and not particularly well! I then tried to borrow my Mum’s however, it did not have Windows installed, then I tried to install it on a work computer and there is a firewall blocking it……. Frustration!! So, Donna has suggested that there may be a Mac equivalent for one of the tasks. I emailed for the trial, however nobody from the company got back to me, so I will follow that up next week.

Task 2

I have had fun working on task two this week. I did find that in the bright daylight it was often difficult to see the Ipad with the glare. I did a google search and found a website that recommended polaroid glasses – so I bought some. They did not help at all – so I am yet to decide whether or not they were really polaroid or if the tip was not a good one? Either way, screen glare is still an issue.

My favourite app is definitely the Coach’s Eye. It is so easy to use and with the Ipad screen being larger, the athlete’s find it much easier to see. They are also enjoying the slow motion footage that I send them after the training session and often say that they finally are able to see exactly what they are doing wrong. I did have one instance where it was not that successful. I was coaching a novice amateur and he was unable to critique his own performance as he did not have the prior knowledge to or experience of what was correct. In this example, I think the split screen comparisons would be most valuable.

Here is an example of how I used Coach's Eye this week……



The other thing that I am looking into this week is the sharing options. I now have my own account “cloud” to which all my reviews are done.  I can see how many times they have been viewed (by the athlete) and decide whether or not to make them public or only available to those with the link.
