4 Main claim to fame…….!!!

5  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 Contents

6 Video Analysis

7 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 Video Analysis

8 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! Video Analysis

9 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 Video Analysis

10  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 Video Analysis For GKs Overview

11 Video Analysis For GKs GK Performance Analyst AnalystCoachPlayer

12 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 Video Analysis For GKs

13 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. Video Analysis For GKs

14  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 – GKCoach – 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 Video – GK Development Plans

15  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 Video – GK Development Plans: Matches

16  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 Video – GK Development Plans: Training

17  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! Video – GK Development Plans: Training

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 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! Biomechanics

27 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 Biomechanics

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

29 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 Biomechanics

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


32 Crossing: 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)

33  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? Biomechanics

34  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 Biomechanics

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

36  Why not??? Biomechanics

37  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……. Biomechanics

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 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 Performance Analysis

41 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 Performance Analysis

42 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 Performance Analysis

45 Saving SnapShot Performance Analysis

46 Saving SnapShot Performance Analysis

47 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 Performance Analysis

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

49 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 Performance Analysis

55 Goals Analysis Performance Analysis  Save in the red zone  Tailored to different ages/abilities  Relate to goal setting  Save the balls in and around

56 Goals Analysis Performance Analysis

57 Goals Analysis Performance Analysis

58 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 Performance Analysis

59 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 Performance Analysis

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  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 Research

64 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……. Research 1

65 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 Research

66 Games Based Training

67  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 Games Based Training

68  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 Games Based Training

69  Triangle Goal Game Games Based Training

70  Multi-Goal Games Based Training

71 The Future

72  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) The Future

73  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 The Future

74  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 The Future

75  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!!!
