11.2 - Notational Analysis

• Reasons to use Notational Analysis

  • provides an objective way of recording performance
  • makes feedback from coach to performer easier and more precise
  • quatifies performance in a consistent and reliable manner
• Tactical Evaluation


  improving the strategy by studying the tactics for future opponents
• Analysis or Movement


  in sports such as foootball, tracking systems placed in players do this work for you

  
• Technical Evaluation


  Identifying and diagnosing faults in technique in performers

  
• Development of Databasses and Models


  enabled predictive modelling which can enhance future training and performance
• Educational Use with Teacher/Coach and Athlete

  Provides instant visual feedback to the performer

  
• Speed Principles

  time taken, distance travelled
• Force Principle


  newtons laws: 1st law: inertia, 2nd law: acceleration (F=M/A) and 3rd law: action/reaction
• Coordination Principles


  while learning, part learning, part-whole learning
• Specific Performance Principles


  height of release, angle of release and speed of release
• Phase Analysis Model - Preperation


  what Happens: the way in which the performer sets or prepares for the performance of the skill

  Example: the ball is placed in the soccer penalty kick, the golf club is held
• Phase Analysis Model: Retraction


  What Happens: with drawl of prior to beginning the main efffor of the performance

  Example: drawing leg back to kick a football, backswing in tennis
• Phase Analysis Model - Action


  What Happens: the main effort of the performance of the skill

  Example: forward motion in tennis serve, throwing action in javelin
• Phase Analysis Model - Follow-through


  What Happens: allows movement to be slowed down under control

  Example: forward swing across the body in tennis
• Scattergram


  involved recording notes of action where’d they happen on the court/field of play

  
• Frequancy Tables


  used to track the exact amount of times each player performed and action or skill, scored or lost possession etc

  
• Sequential Systems


  record the sequence of actions that led up to a critical performance or event like a penetrative pass or shot at a goal

  
• Hawkeye


  A large platform used in professional sports, used to challenge umpires in sports like tennis and cricket where the calls can be very tight and very important in the match
• Dartfish


  a software which analysis an athlete’s performance in slow motion, it can be used to compare performers side by side
• Pro’s of digital technology in sports


  provides data not available through traditional analysis techniques, provides data over shorter or longer timescales, data is objective and accurate, processed data improves visualisation and allows image comparison
• Con’s of digital technology in sports


  Coaches need training to make effective use of it, limited availability in many regions, limited use of situations, may lead to over-reliance on objective data, many software technologies are relatively inexpensive
