Q4E Case Study 2 - Performance Analysis and Evaluation

Proposed Subject usage:

Sport and PE (GCSE/A level)


National Curriculum (Key Stage 4)


Evaluating and improving performance. Judge how good a performance is and decide how to improve it

AQA GCSE PE Specification

Analysis of performance

The specification will assess a candidate’s ability to analyse performance so as to:

  • Determine its strengths and weaknesses
  • Improve its quality and effectiveness
AQA A Level PE Specification
At AS, candidates are required to observe, analyse and evaluate performance.

Observe the chosen performer in relation to the competent performance of the 5 specific techniques for a chosen activity

Ways in which Quintic software can be used in PE:

Evaluate the performer’s strengths and weaknesses of the core techniques in their sport in relation to the competent performer by identifying and justifying the greatest weakness and suggesting how to bring about improvement.

Use Quintic features, including frame-by-frame analysis, to identify strengths and weaknesses in student’s technique (using Quintic video capture).
In order to facilitate an improvement in performance, candidates are expected to research and understand the correct techniques for the core skills.
Research elite performers’ technique from detailed analysis of video files taken from the extensive Quintic video library covering a huge variety of sports.
Compare their performance against the competent performer by identifying the causes of strengths/weaknesses in the technique of the core skills.
Compare students’ performance (captured from video) against elite performers using main and best windows.


Functions of the Quintic Software used:

  • Digitisation module and Calibration
  • Video capture
  • Export *.avi function
  • Interactive graph and data displays
  • Multiple image capture
  • Shapes and angles

Analysis of chosen sport – Swimming:

Five main areas to evaluate are:

  1. Starts/Turns
  2. Head/breathing
  3. Body position
  4. Leg action
  5. Arm action

Track start

Distance off blocks: Female swimmer – 2.2m Male swimmer – 2.4m

The Female swimmer:

  1. Keeps her legs apart during the flight so is not optimally streamlined.
  2. Holds arms lower so does not gain as much distance.

The Male swimmer:

  1. Gains a lot of height from the blocks during the flight phase by throwing his arms forward and up.
  2. Keeps his hips high during flight and raises his legs before entry.
  3. Head and arms are streamlined with head tucked between arms.

Backstroke tumble turn

  • Glides in a streamlined position with arms above head
  • Tumbled slightly too far away from the wall
  • Knees bent for maximum push off
  • Turned through too much of a full rotation
  • Head raised and back not horizontal – therefore pushed off upwards

Front crawl stroke technique

  • Body position – the swimmer is in a prone position with head low in the water, legs are relaxed and extended in a streamlined position. The swimmer rolls well from side to side during each stroke.
  • Leg action – the swimmer uses the ‘flutter kick’ action, has good ankle flexibility and knees are not too bent.
  • Arm action – ‘S-shaped’ pull phase has good inward and outward sculling movements. The recovery is efficient with a bent arm and high shoulder; the swimmer stretches the arm out in front ready for hand entry.
  • Head and breathing – rotates head to the side efficiently - only enough to take a breath.


Quintic Software can be used to capture, observe and evaluate video footage of the students performing their chosen sports. Analysis of their performances can be performed with ease using the wide variety of functions offered by the software. The videos can also be compared with similar skills performed by elite athletes (such as the videos shown above) taken from the vast selection in the Quintic video library.
