  4. About Andy Main claim to fame…….!!!

  5. Contents Video Analysis – History, Systems& Implementation Biomechanics – Movements & Techniques Performance Analysis – Created Systems Research Games Based Training The Future All of the stats are fictitious – only to show how the system works Can only show certain clips – mainly to show processes not specific information

  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

  11. Video Analysis For GKs

  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

  19. 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’ 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. Diving Power and Angle: Unfortunately can’t show my detailed work here…

  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 • 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) Crossing:

  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

  43. Performance Analysis Saving SnapShot

  44. Performance Analysis Saving SnapShot

  45. Performance Analysis Saving SnapShot

  46. Performance Analysis Saving SnapShot

  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
