Notational analysis - SEHS
Educational use
Allowing the athlete or coach to an opportunity to reflect and review
Nutrition, fitness and training analysis software
Apple watch/fitbit Bodybyte
Technical evaluation
Awareness of biomechanical breakdown and technical deficiencies compared to correct technique model eg. axes or rotation, angle of release
Limitations of using technology
Effectiveness of data is determined by coaches knowledge and application May lead to over-reliance of objective data Feedback can be delayed/outdated
Motion tracking and capture devices
Hawkeye - tennis and football Dartfish - angles
Analysis of movement
How and why the body moves eg. analysing a flip sequence in a floor routine
Team game options for notational systems
Scattergrams Frequency tables Sequential systems
Development of databases and models
Storing and logging information for future use eg. PE teachers logging fitness performances in the community longitudinally
5 applications of notational analysis
Tactical evaluation Technical evaluation Analysis of movement Development of databases and models Educational use with teacher/coach and athlete
Define notational analysis
The permanent recording of information about practice or perfomances in a systematic and objective way
Frequency tables
Used to record tallies of events/skills eg. number of successful passes made by defenders in a football match
Phase analysis of a projectile
Run up Plant Take-off Flight Landing
Tactical evaluation
Observations on strategy, patterns of play and set plays eg. % of possesion
Strengths of using technology
Provides data that is not available through traditional techniques Allows coaches to set targets Data is objective and accurate Software is normally relatively inexpensive
Goals of notational analysis
Provides objective data Quantifies performance Facilitates quantitative and qualitative feedback
Performance analysis software
Prozone - football
Phase analysis
Qualitative data Breaks down movements into phases Preparation Retraction Action Follow-through
Performance analysis
Quantitative data Addresses mechanical factors that affect performance Speed and acceleration principle Force principle Coordination principle Specific performance principles eg angle of release, height of release/jump etc
Sequential systems
Record chronologically ordered list of events in a match eg. position of team during transition
Scattergrams
Represent the playing area and allow for location of events eg. location of shots in a football match
