6. Video Analysis

7. Video Analysis Quick Background
A key component of the coaching process
Reduces the gap between subjective (views and opinions) and objective (evidence and observations) reasoning
Used to monitor, develop, measure and enhance Key Performance Indicators – KPIs
Positive re-enforcement – especially for young GKs
Due to my experiences in goalkeeping can tailor everything to meet needs and work closely with coaches
PROVIDES EVIDENCE

8. Video Analysis Easily accessible???
Basic video cameras come with editing software
Free software available online
Not as expensive as you might think
Benefits and supplement to coaching –
Priceless!

9. Video Analysis Software
SportsCode – very advanced and powerful analysis tool
Kinovea – My own software – used at other clubs and in my own coaching
Storage of sessions
Library of saves, technical points and feedback examples

10. Video Analysis For GKs Overview
Looked around for analysis systems for GKs……….didn’t find anything useable
Very generic and not GK specific
Using general football ideas and research through Msc and coaching was able to explore new ideas
My Msc dissertation found a large gap in GK video and performance analysis at youth development level
Through starting video support in my own sessions has enabled me to be in the position I am today

12. Video Analysis For GKs Match Viewing
Traditional ‘TV’ view gives limited feedback opportunities i.e. usually when the GK is directly involved in play
Previous research dictated that GKs aren’t involved in play 85% of the match (based upon 1 season – don’t need statistics to realise this)
Wanted to investigate ‘off the ball’ involvement
Have tried filming from behind the goal for GK’s view
Came up with a GK player cam and match view playing together

13. Video Analysis For GKs Match viewing
Opens up previously neglected areas:
Positioning without the ball
Support play
Communication
Starting positions
‘Coding’ specific to GKs – when matches are reviewed the individual clips are broken down into the above areas along with shots, crosses, set plays, counter attacks and distribution.

14. Video – GK Development Plans
Built into their weekly plans – specific sessions
Mon – Matches/Thurs – Weekly Training (Also when necessary)
Constant liaising with coaches
Done in the following ways:
Coach – GK Coach – GK – Analyst
Analyst – GK (after consultation with coach)
1 GK or a group depending on the analysis session
Used to assist report writing and performance monitoring e.g. jump testing

15. Video – GK Development Plans: Matches
GK would look back at their coded match areas with the coach on a 1 to 1 basis
My role as analyst is to prepare selected clips and whatever information the coach wants (more on this later)
Coach would feedback their points from the game. A very interactive process that gets the GK thinking about their whole performance
When coaching I do this myself so assuming both roles

16. Video – GK Development Plans: Training
Broken down into small clips or 1 main coaching point
Most feedback takes place after the session
In some instances the coach will stop the session and use immediate feedback looking at the clips there and then
Comparisons of techniques – split screens
Zoom in to really dissect technique
Widescreen to look at set position and positioning in the goal
Experimented with various angles – depending on the coaches direction or session topic e.g. dive angle

17. Video – GK Development Plans: Training
2 cameras for the same action (gives a good reflection how the GK is moving)
Young GKs love seeing videos! Use this engagement to productive a productive environment
Short – sweet – to the point…don’t overload with hours of clips focus on the points you want to make
Structure is the key!

18. Examples

20. How To Use?
The GKs work mostly on their own performance, but also the below model can be applied:
Self – own performances
Peers – others in their club/age group to start discussion and questions
Ideal – Pro GKs – Match of the Day
Saves of the week, YouTube videos
Question sheets and grading used

21. How To Use? Ideal Model – However…
Previous academic research states that this approach can be dangerous because it assumes this skills are applicable to all levels of performance…
A need to keep reviewing the ‘most appropriate’ skills and techniques
Based upon areas such as ball changes, player evolvement, roles in the team and trial and error of practice
Are there ‘ideal’ saves or movements for Gks?
KEEP CHALLENGING OURSELVES!
BE ONE STEP AHEAD OF THE OPPOSITION

22. How To Use?
Interactive session plans – example real life video drills next to traditional session plans
iPad being worked on
Feedback presentations – using video clips of the ‘ideal’ drill execution or exercise to compare their session to
Selected video clips on a PowerPoint video annotated notes and coaching points on

23. Coach Assistance… Head down…strike the ball…???
When serving and involved in the session…sometimes hard to see the GKs initial movements and saves
So much going on in a session
Video allows for recall of all incidents! Assists the coach to look at sessions and matches retrospectively

24. Summary
An extremely powerful tool if structured and delivered appropriately
Tried and tested a variety of different feedback and interaction methods
Easy to use if the basic resources are available, You don’t need high-tech software to produce video analysis
Ever growing and evolving area of goalkeeping development and performance

25. Biomechanics

26. Biomechanics Overview Study of human movement Looked at:
Set positions – grounded feet upon shot impact
COM – velocity, quickest route…
Dive angles
Power step and force movement
Jumping techniques
General motor skills in relation to goalkeeping
Other sports
Cant show the best examples unfortunately!

27. Biomechanics Basic Handling: Where the GK catches the ball
Relating to their body
Watch the ball!
Wouldn’t believe throughout all the sessions + matches how many GKs don’t watch the ball

28. Biomechanics Diving Power and Angle:
Unfortunately can’t show my detailed work here…
‘Diving’ Position
Head - Behind the ball.
Hands - Will lead, take the ball early as possible and keep the elbows in front of the line of body.
Feet – Step off the nearest foot to the ball, off the front studs at a 45 degree angle.

29. Biomechanics Diving Power and Angle:
Working on moving head and hands towards the ball
Stronger body shape
Stepping into the dive and not collapsing
Quicker movements – broken down into 3 areas of analysis
Previous research – in addition to my own analysis and observations over the past few years

30. Biomechanics
Diving Power and Angle:
Initiation
Take off
Ball contact

31. Biomechanics

32. Biomechanics Crossing:
Working on the ‘standard’ crossing coaching points
Point the toe ‘up’ to engage the leg muscles for more power and stability
Working a lot of ‘timing’ and the ‘decision making’ behind crossing – a lot of video work (initial movements)

33. Biomechanics
Watched hundreds of training sessions, matches, gym sessions!!!
Goalkeeping is a 360 degree reaction position, not just reaction saves but responding to crosses, through balls, shots, defensive situations, starting attacks etc…
Very rarely are 2 actions ever the same – obviously similarities but due to the nature of the game movements are always varied – need to practice ‘unorthodox’ actions – examples?

34. Biomechanics Use/advocate quick powerful movements: Plyometrics
Futsal, Basketball, Handball, Tennis, Badminton, Hockey, Volleyball and Gaelic Football movements – similarities from all sports – Youth Level
Powerful – Quick – Dynamic – Reaction – Agility
Train in isolation/build into technical practices
Based upon research and observations + Use in my own coaching

35. Biomechanics
Varied unpredictable practice (more on this later…)

36. Biomechanics
Why not???

37. Biomechanics
Gets the body moving in ‘irregular/non linear ways’ – which is what a GK performs in a match
Do we coach the drill or the actual session topic?
Should we coach a variety of techniques and movements so the GK is ‘equipped’ with the tools to be successful in any situation?
Have GK’s using their whole bodies to save if necessary
More on my research later on…….

38. Summary
Take elements of other sports actions – training – movements into GK training
Add to the specific match training
Studies have looked to find areas to improve i.e. dive techniques, jumping
Ways to which to work on these
A lot more work to be done – more on this at the end

39. Performance Analysis

40. Performance Analysis Overview
Performance Analysis is the holistic part of the roles I’ve assumed
Combining video, biomechanics, statistics, coach dialogue, development plans, feedback, performance monitoring, psychology – the whole process
Statistics – good but can be misleading at times…used to try and add a different dimension
A vital part of the coaching process

41. Performance Analysis Statistical Saving SnapShot
A more accurate way of measuring saves ratios – ‘Johnny your save % this season was 65%’...what does that even mean!!!
What kinds of saves? What type of shots? Where from?
Without over-kill here, have designed this system
See hand-out for more details

42. Performance Analysis Statistical Inspired by… Moneyball!
Wanted to investigate statistics in GKs further
To see if I could find ‘relevant’ and ‘useable’ data for coaches
Examples of a few systems – ever evolving but used for past 2/3 seasons at youth and pro level

47. Performance Analysis Saving SnapShot Looking for trends
Records saves and goals ratios
Easy to record
Always looking to evolve and make more accurate
Plans to add ‘saves with the feet’ along with a few more ideas
Some coaches prefer visuals, some statistics
Always important, if possible, to have video footage to backup the statistics

48. Performance Analysis Distribution
Created 4 years ago – found a couple of similar methods but didn’t produce the statistics I wanted
Measures:
Frequency
Success
Retention

49. Performance Analysis Distribution Pitch Maps Trends
Individual Distribution Actions
Time on the ball – long/short distribution
Overall statistics – see hand-out (wouldn’t give all this information to a coach

Simple way of recording where goals go in
Looking for trends
Not just for the GK
Usually done with older GKs but always good to monitor
Examples…….

58. Performance Analysis Psychology
Worked with various GKs at different levels
Specific GK work
Have used different questionnaire + interview based techniques
Looked at building confidence, dealing with anxiety, coping with mistakes and improving concentration
Performance profiles, imagery, visualisation, positive mind set…
Not the main emphasis of the presentation – speak to me at anytime for further details

59. Performance Analysis Psychology
Performance Profiles – main area linked to video analysis – won’t give away all my secrets!
Gets the GKs to review their own performances/attributes and combine with coach views
Linked to identifying the crucial attributes of top GKs
Selecting the best attributes from each top GK to create the ultimate GK!
All linked to the video analysis work done

60. Summary Crucial in the coaching process
Find a way to measure, test or monitor an area of performance – if nothing exists for what you want…create it!
Can be tailored to the ability, age and experience of the GKs you’re working with
Can be replicated at grassroots level quite easily
New systems being created all the time

61. Additional Areas

62. Research

63. Research
Am presenting 2 podium presentations at the ISPAS (International Society of Performance Analysis in Sport) World Congress in July
1 – based around logging match actions over 2 whole seasons and comparing to the actual training sessions – do we train what occurs in matches?
2 – an overview of my Performance Analysis support systems over 4 different clubs from a scientific approach

64. Research 1
1 – based around logging match actions over 2 whole seasons and comparing to the actual training sessions – do we train what occurs in matches?
Findings this was not the case
Agreed with a 2012 FIFA study
Suggestions on different ways to train
GK as a playmaker!
Results – ISPAS 2012…….

65. Research
2 – an overview of my Performance Analysis support systems over 4 different clubs from a scientific approach
Goes into detail about my work and research
Similar to what I’ve done today

66. Games Based Training

67. Games Based Training
Developed over 6 years to offer a different approach to technical training 80+ games
Designed for coaches with 4+ GKs
Focuses on different topics (shot stopping, 1 v 1s etc) within small specially designed games
Works on all motor skills in a fun learning environment
Used with grassroots and elite GKs with a great deal of success and positive feedback

68. Games Based Training
Combine a variety of different sports, balls and environments
Works closely with the biomechanics chapter to develop core motor skills and general athleticism
Focuses on the TGfU coaching theory
Places the learning emphasis on the goalkeeper
Ask questions into their performance
Lets them find appropriate techniques for different situations

69. Games Based Training
Triangle Goal Game

70. Games Based Training
Multi-Goal

71. The Future

72. The Future
Studying into how we make decisions and how our body reactions to different scenarios
Detailed study into GK biomechanics and motor control
Main question…….
Do our bodies respond differently to prescribed or varied practice?
Looking into muscle activation and the importance of the ‘power step’ and not collapse dives (biomechanics part of presentation)

73. The Future
Why do we tell the GK where the ball is going during technical training?
From a novice (cognitive learning phase)
Prescribed good for familiarity and building confidence
Later on in development need to work more varied – more decisions

74. The Future
Building upon 2 previous studies – although the findings/experiments can be improved
Coach friendly results
Have an initial willing participant!
Looking to build an intervention study

75. Conclusion Brief insight into some of the areas I’ve looked into
Everything based on my experiences
Trial and error of numerous systems
Always looking to improve
More systems, methods and experiments on-going
‘Scientific Approaches to Goalkeeping in Football’ being developed
Improving GK performance and sharing ideas!!!

76. Conclusion
