PQ 13.3 QUANTITATIVE ANALYSIS OF HUMAN MOVEMENT

What is the primary purpose of quantitative analysis in human movement?

• To provide subjective assessments of movement

• To generate numerical data to measure and quantify movement

• To rely on the observer's memory for analysis

• To use only simple mathematical models

Which of the following is an example of a simple quantitative analysis?

• Using a video camera to track a runner's foot-strike pattern

• Timing a 200 m sprint with a stopwatch

• Using force plates to measure an archer's balance

• Modelling Usain Bolt's sprint using complex equations

What is the "Timed Up and Go (TUG) Test" used to assess?

• The speed of a runner

• The severity of disability in a person needing hip replacement surgery

• The balance of an archer

• The foot-strike pattern of a runner

What was Usain Bolt's average linear velocity during his 2009 world record 200 m sprint?

• 8.42 m/s

• 9.42 m/s

• 10.42 m/s

• 11.42 m/s

What percentage of energy did Usain Bolt use to compensate for drag during his world record sprint?

• 72.21%

• 82.21%

• 92.21%

• 100%

What is one advantage of quantitative analysis?

• It relies on the observer's immediate knowledge

• It provides subjective measurements

• It offers objective numerical measurements

• It is inexpensive and requires no technical skills

Which of the following is a limitation of quantitative analysis?

• It is always conducted in real-life settings

• It requires inexpensive equipment

• It can be time-consuming to complete

• It provides subjective assessments

What is a common tool used in simple quantitative analysis of human movement?

• Video equipment

• Automatic marker-tracking systems

• Stopwatch

• Force plates

What is the formula used to calculate average linear velocity?

What is one reason why complex mathematical models are often not used by teachers or coaches?

• They are too simple to be useful

• They are mainly used by researchers

• They provide subjective data

• They are inexpensive
