MULTIDISCIPLINARY APPROACHES TO
IMPROVING TABLE TENNIS PERFORMANCE –
PRACTICAL EXAMPLES FROM ASPIRE ACADEMY
Dr. Jonathan Glynn, Senior Biomechanist
• ASPIRE AND THE SERVICE TEAM APPROACH
• MULTI-DISCIPLINARY EXAMPLES:
1. PERFORMANCE ANALYSIS (PA) AND STRENGTH AND CONDITIONING (S&C)
2. PA AND COACH ASSESSMENT OF TECHNIQUE CURRICULUM
3. PA TO SUPPORT COACH ASSESSMENT OF MATCHES
4. PA TO INFORM PSYCHOLOGY

SERVICE TEAM APPROACH
Reaction time, alertness, anticipation
(psychology & biomechanics)
Stroke mechanics- Segment kinematics, video feedback
(biomechanics)
Agility- Lateral, forward and
rotational movement (footwork)
- (s&c, physio, biomech)
Power (explosive)(biomech, s&c)
Shot Accuracy (biomech)
Decision making (rapid and correct)(psych)
Arousal / Anxiety(psych, physiology)
Injury risk screening(physio, medical, S&C, biomech)
Psychological characteristics for developing excellence (PCDEs) (psych)
Metabolic demands of table tennis with reference to sweat loss and influence on cognitive abilities/fatigue (physiology, nutrition, psych)
Training and trainability (physiology, S&C, physio)
Competition preparation(multidisciplinary)
NEEDS ANALYSIS
FOCUSSED ON TARGETED PLAYERS
HIGH IMPACT IN TRAINING AND COMPETITION
• These two disciplines work closely together (movement orientated)
• PA can inform changes to S&C training
• Tests for monitoring physical skills e.g. agility can be derived from PA data
PERFORMANCE ANALYSIS (PA) AND STRENGTH AND CONDITIONING (S&C)
WHY TEST YOUR PLAYERS?
INFORM TRAINING
APPLIED RESEARCHTRACK PROGRESS, COMPARE INDIVIDUALS
AGILITY TEST DEVELOPED FOR S&C COACH
PERFORMANCE ANALYSIS OF ASIA CADET CHAMPIONSHIPS FINAL
• coded game live using iPad (iCoda)
DEVELOPING ATTAT
- temporal analysis of matches (activation -work - rest)
• video (footwork grid of 36 squares 0.425 x 0.425 m)
- rally length analysis (no. of shots and time)
- movement types; footwork patterns

DATABASING AND SHARING DATA
• Is your S&C program related to performance?
• How is physical performance monitored?
• How are test results shared and used to modify training?
TALKING POINTS
• “You can’t quantify table tennis technique”
• I think you can BUT this needs the coach to educate the performance analyst and vice-verca
• Just because something is not ‘normally done’ in table tennis doesn’t mean it shouldn’t be tried…someone has to be the first
PA AND COACH ASSESSMENT OF TECHNIQUE CURRICULUM
• Track progress in a standardized way
• Set targets for players
• Compare between players
• Management like numbers!
BENEFITS OF QUANTIFYING ASSESSMENT PROCESS
DEVELOPING TECHNIQUE CRITERIA
ASSESSING TECHNIQUE CURRICULUM
ASSESSING TECHNIQUE CURRICULUM
FUTURE DIRECTION
• Are you open to new ideas?
• Don’t be afraid to have the difficult discussions as they might be the ones that lead to good work happening
TALKING POINTS
• Software packages are a great way of speeding up and improving the quality of feedback from matches to coaches and players
• Burning dvds is in the past with new cloud technology!
• Players love their smartphones so embrace that
• Dartfish TV and Smartabase
PA TO SUPPORT COACH ASSESSMENT OF MATCHES
BACKGROUND
DARTFISH TV UPLOAD AND FEEDBACK FOR PLAYERS
DATABASING FOR COACH TO ADD EVALUATION
• What feedback is appropriate for coaches and players?
• How are you getting this feedback to coaches and players effectively?
TALKING POINTS
• Competition video can (and should) be used by every member of a service team
• Theory from text books is not so meaningful to a young player – practical examples from his matches are
PA TO INFORM PSYCHOLOGY
• Athletes are not always aware of extent to which they display non-behavioral patterns
• Non-verbal behaviors have been thought to have causal influence on next point
PRACTICAL EXAMPLE – BODY LANGUAGE
• From 5 games (3 won, 2 lost) against players of similar technical and tactical ability
• 2.1 actions per point (games won) and 3.4 actions per point (games lost)
• Identify strengths and weaknesses from PA
• Set SMART goals with view to minimizing behavioral patterns associated with failure and maximizing those resulting in success
• Period monitoring and review using PA data
THE PROCESS TOWARDS PERFORMANCE IMPROVEMENT
• Are you maximizing output from the match video you collect?
• Are you (the coach) and the player aware of his / her strengths and weaknesses from a psychological perspective?
• Have you set goals and is there a systematic approach to monitoring them?
TALKING POINTS
• Leadership – clear goals and direction
• Communication – sharing of data and ideas
• Openness to new ideas, processes, technologies (step out of comfort zone)
• Using each others strengths for the betterment of the service team
• Athlete centered approach to servicing as a TEAM
