1 Performance Analysis and Technology in Sport where we are now where do we need to be Presented by: Ryan Hodierne 17 November 2012

2 Performance analysis Limits the element of subjectivity Simplifies the process of feedback Minimizes the element of surprize in competition Data is there to reinforce what the coach and the athlete thinks Allows to alter tactics to minimize the opponents strengths and optimize their weaknesses If you can measure something, you can improve it

3 Although in the past there was some resistance to the use of data in sport and some sports are still reluctant to wholeheartedly embrace and put faith in the power of analytics over the last few years there has been a sea of change in attitude Stafford Murray (head of performance analysis & biomechanics at the EIS)

4 2012 London Olympics medal tally

5 2012 London Paralympics medal tally

6 Team GB Olympic Funding UK Sport invested ± 550mil over the Beijing and London Olympic cycles Olympic expenditure comparisons: - Beijing = 235,103,000 (± R 3,3mil) - London = 264,143,753 (± R 3,7mil) Team GB spending per sport for London 2012 Rowing Cycling - 27mil - 26 mil (high cost due to expenditure on latest technology bikes / helmets / clothing hot pants ) Athletics - 25 mil Swimming - 25 mil

7 Team GB cost per medal for 2012 Graph compliments of The Guardian Posted by Koos Couvée Monday 13 August 2012

8 Team GB Olympic Funding Boxing = most cost effective with 5 medals, 3 gold Cycling and Rowing = best value for money Cycling: - 12 medals, 7 gold in track discipline - Quoted as being the better team due to technological superiority - Each cycling medal = 2.2mil (R31mil) Rowing: - 9 medals, 4 gold - Big on technological support - Each rowing medal = 3mil (R42mil) Swimming: - 3 medals, 1 silver / 2 bronze - Each swimming medal = 8.4mil (R118mil) Average cost per Team GB medal = 4.6mil (±R64mil)

9 Medal tally: hosting vs. non-hosting

10 Olympic funding Hosting nations get an injection of financial support However money does not buy medals! Though money does - Allow for high-tech testing - Prolonged research and development - Allow for trial and error - Time in a wind tunnel

11 Technological intervention in Sport Within an Olympic cycle, four years is a long time when considering the progression of technology.

12 Domains of Technology Information and knowledge management Communications technology Notational analysis Video-based biomechanical analysis Telemetry Databases to monitor and track athletes, as well as data mining technologies. Real time transfer of knowledge and information to athletes and teams within the framework of existing rules and regulations. Objective analysis, quantification and analysis of the critical incidents (tactical and strategic) in game performance that influence outcomes. Technique and performance analysis. Remote monitoring of athletic performance in real time. Simulation and modelling As more data becomes available on players, such as their reaction times, sprint speed, body mass as well as attacking and defending patterns, such information can be used in modelling and simulating performance. Virtual reality VR simulators can be used to enhance the decision making skills in a vast array of sports. CSIR

13 CANOEING, TESTING IN SUBMARINE TANK: Jon Schofield and Liam Heath paddling up and down the 270m pool, with video cameras being used to monitor their speed and split times

14 AERODYNAMICS TESTING: Mercedes-AMG-Petronas wind 3,000 (R 42,000) per day

15 DIMPLED BODY SUITS: drawn inspiration from golf balls and designed to reduce aerodynamic drag; wind-tunnel tests have proven that it can potentially reduce times by second

16 Technological concerns There is a fear of engineering overshadowing the triumph of human spirit and ability A worry that the best athletes might not win The thought of sports engineering giving richer countries an advantage over poorer countries 800m WR (wheelchair) 1980 s = 1:55.67 Current WR = 1:32.17 ( sec!)

17 The controversy Technology doping Swim suits of Beijing world records in swimming alone London world records set in total - 8 world records in swimming - Swimming times continue to get faster ( more focus on technique / better attention to detail)

18 In prevention of these concerns Olympic governing bodies need to pursue the following: - Actively monitor the latest technologies (ideally before implementation) - Planning is required rather than just reacting - Rule books need to be re-written and reviewed over shorter time frames - Closer ties need to be developed with engineering firms

19 ENGLISH INSTITUTE OF SPORT (EIS) HQ in Manchester sites around the country Employs 30 full-time performance analysts Each dedicated to a sporting code 2012 London Olympics: - 17 EIS analysts - Provide visual & data feedback to respective coaches - Captured footage from 40 TV feeds (BOA) - Footage then fed to 23 individual sporting codes via - Dartfish TV web platform for analysis

20 ENGLISH INSTITUTE OF SPORT (EIS) Performance Analysts: London vs Beijing Olympics = 17 vs 5 Paralympics = 4 vs 1 The biggest challenge still - delivering information faster and in a form that can most effectively be used by teams and individuals

21 EIS research and development What they wanted: real-time wireless data tracking for swimming (during training) British Swimming challenged 3 different Universities to develop the technology 8cm x 5cm box fitting into the small of a swimmers back collates data from pressure mats and sensors around the pool data is transmitted to a laptop on poolside data includes: push-off time from blocks airtime during dive total time in contact with wall during turns

22 The use of Simulcam in analysis Allows to split screen views Can analyse pre and post performances - Pre and post injury - Pre and post coach intervention It allows to overlay before and after footage to highlight the differences

23 The use of Stromotion in analysis Track paths of motion Select key positions within complex movement patterns Provides a great coaching tool

24 Mobile Analysis tools and applications

26 Current levels of intervention in SA Sport Race performance analysis - Data feedback on performance variables - Identifying athlete strengths and weaknesses - Pin-pointing areas of improvement - Profiling competitors Creation of athlete databases in performance tracking - Variables include performance / health / psychology Telemetry in training variables of team / individual performances - used in team selection or identifying ideal combinations or techniques Long term athlete development at academy level Minor technological intervention at national / provincial training level

27 Key areas of focus in SA Sport Coaches education - Familiarization with technologies - Tailoring data analysis to their requirements - Equip coaches / assistants with tools and knowledge for self-help Technological support - Educate the necessary people (sports scientists / biomechanists) - Invest in necessary equipment - Implement where it will be of greatest impact - Filter the intervention through to other sporting codes Performance analysis - Implement at club / provincial level - Feedback should be simple but effective - Data should reflect grounding and reliable information - Seek repeatability

28 Key areas of focus in SA Sport (continued) Research and development - Must be on going in as many fields as possible - Should provide practical, real-life and useable data - Results should be applied where applicable Human capital development - Create interest at tertiary level - Avenues of specialization should be made available - Certificate courses and or degrees should be attainable

29 Heading toward Rio 2016 and beyond Greater technological intervention at club and provincial level More consistent scientific intervention during training and competition at national and international levels Continued and collective nationwide, inter-provincial Talent ID

30 Heading toward Rio 2016 and beyond (continued) More regular sport / athlete database updates from more frequent events Consistent athlete performance tracking - at national and international level Allocation of performance analysts to priority sporting codes - must be given other codes to advance with in coverage of all Olympic codes - Team SA to London 2012 = 17 sporting codes - The bare minimum requirement of analysts for any sort of impact 2 3 notational analysts (team sports) 3 5 performance analysts (roaming)

31 In conclusion Technological support is really there for quality control Performance analysis is an additional tool to the coach Analysis will never replace the human aspect of performance Technological support in performance analysis in professional sport can no longer be an after thought!
