Analysis using technology

Question 1

Name the three technological methods used to analyse movement

Answer 1

Limb kinematics, force plates and wind tunnels

Question 2

Describe limb kinematics

Answer 2

• The study of movement in relation to time and space
• 3D or optical motion analysis records the athlete’s movements so joint and limb efficiency can be analysed
• Video and infrared cameras convert to digital imaging

Question 3

Give one advantage and two disadvantages of limb kinematics

Answer 3

+ immediate and highly accurate
x highly specialised = expensive
x limited to laboratory use

Question 4

Describe force plates

Answer 4

Measures the size and direction of the force applied by the performer and acting on the performer to analyse gait, balance and posture (rehab)

Question 5

Give two advantages and two disadvantages of force plates

Answer 5

+ immediate and accurate
+ health and performance
x specialised = expensive
x may psychologically affect performer to adjust their normal technique

Question 6

Describe wind tunnels

Answer 6

Assessing the effects of drag to design equipment

Question 7

Give one advantage and two disadvantages of wind tunnels

Answer 7

+ control of environment
x specialised = expensive
x complex analysis of results
