Goalkeeping Performance Analysis Andy Elleray Slide 2 About Andy 24 years old, from London Enjoy filming! Statistics! The mind! Writing! Slide 3 Football Analysis: Cheltenham Town, Liverpool, Chelsea Coach: Cheltenham Town, Hereford United, Worcester City, Worcestershire FA Playing: Amateur/Semi Pro, 8 different Sports at University, Great Britain & England Blind Football (sighted goalkeeper) Academic Msc Sports Coaching, Bsc (hons) Sports Science, Diploma in Sports Management UEFA B + UEFA B Goalkeeping - currently completing ISPAS (International Society of Performance Analysis in Sport) Accredited Level 6 analyst About Andy Slide 4 Main claim to fame.!!! Slide 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 Slide 6 Video Analysis Slide 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 Slide 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 Slide 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 Slide 10 Looked around for analysis systems for GKs.didnt 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 Slide 11 Video Analysis For GKs GK Performance Analyst AnalystCoachPlayer Slide 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 arent involved in play 85% of the match (based upon 1 season dont need statistics to realise this) Wanted to investigate off the ball involvement Have tried filming from behind the goal for GKs view Came up with a GK player cam and match view playing together....... Video Analysis For GKs Slide 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 Slide 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 Slide 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 Slide 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 Slide 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 pointdont overload with hours of clips focus on the points you want to make Structure is the key! Video GK Development Plans: Training Slide 18 Examples Slide 19 Slide 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 Slide 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 Slide 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 Slide 23 Coach Assistance Head downstrike the ball??? When serving and involved in the sessionsometimes 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 Slide 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 dont need high-tech software to produce video analysis Ever growing and evolving area of goalkeeping development and performance Slide 25 Biomechanics Slide 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 Slide 27 Basic Handling: Where the GK catches the ball Relating to their body Watch the ball! Wouldnt believe throughout all the sessions + matches how many GKs dont watch the ball Biomechanics Slide 28 Diving Power and Angle: Unfortunately cant 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. Slide 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 Slide 30 Diving Power and Angle: Initiation Take off Ball contact Biomechanics Slide 31 Slide 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) Slide 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 Slide 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 Slide 35 Varied unpredictable practice (more on this later) Biomechanics Slide 36 Why not??? Biomechanics Slide 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 GKs using their whole bodies to save if necessary More on my research later on. Biomechanics Slide 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 Slide 39 Performance Analysis Slide 40 Overview Performance Analysis is the holistic part of the roles Ive assumed Combining video, biomechanics, statistics, coach dialogue, development plans, feedback, performance monitoring, psychology the whole process Statistics good but can be misleading at timesused to try and add a different dimension A vital part of the coaching process Performance Analysis Slide 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 Slide 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 Slide 43 Saving SnapShot Performance Analysis Slide 44 Saving SnapShot Performance Analysis Slide 45 Saving SnapShot Performance Analysis Slide 46 Saving SnapShot Performance Analysis Slide 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 Slide 48 Distribution Created 4 years ago found a couple of similar methods but didnt produce the statistics I wanted Measures: Frequency Success Retention Performance Analysis Slide 49 Distribution Pitch Maps Trends Individual Distribution Actions Time on the ball long/short distribution Overall statistics see hand-out (wouldnt give all this information to a coach Performance Analysis Slide 50 Distribution Slide 51 GK Conference FC v Barcelona Andy Elleray - 16/06/2012 Key Won Poss Retained Won Poss Lost Lost Poss Retained Lost Poss Lost Throw 1 st Half 2 nd half Slide 52 Distribution Performance Analysis Match + GK GK Actions WonLost%RetainedNot% Barcelona (AE) 128467%11192% Real Madrid (AE) 3023777%201067% Ajax (AE)2726196%22582% Total69571282%531677% Can be done for each GK, Home/Away or different competitions Slide 53 Goals Analysis 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. Performance Analysis Slide 54 Goals Analysis Performance Analysis Slide 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 Slide 56 Goals Analysis Performance Analysis Slide 57 Goals Analysis Performance Analysis Slide 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 Slide 59 Psychology Performance Profiles main area linked to video analysis wont 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 Slide 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 wantcreate it! Can be tailored to the ability, age and experience of the GKs youre working with Can be replicated at grassroots level quite easily New systems being created all the time Slide 61 Additional Areas Slide 62 Research Slide 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 Slide 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 Slide 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 Ive done today Research Slide 66 Games Based Training Slide 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 Slide 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 Slide 69 Triangle Goal Game Games Based Training Slide 70 Multi-Goal Games Based Training Slide 71 The Future Slide 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 Slide 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 Slide 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 Slide 75 Brief insight into some of the areas Ive 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!!! Conclusion Slide 76 We cannot solve our problems with the same thinking we used when we created them. Albert Einstein Conclusion Slide 77 Questions
