Question 1

What are limb kinematics?

Answer 1

A study go movement in relation to time and space.
Reflective markers are placed on different parts of joints and limbs, the athlete then performs a movement which is picked up by multiple video or infrared cameras.

Question 2

Why might limb kinematics be used to optimise performance in sports?

Answer 2

You can use it to:
-analyse joint movement to optimise performance e.g. a golf swing to get the perfect angle at the elbow
-analyse techniques e.g. a football free kick to find the optimal joint movement

Question 3

What are force plates?

Answer 3

A specialised scale that can measure the size and direction of forces acting on an athlete

Question 4

Why would force plates be used in sports?

Answer 4

To measure acceleration rate, power output, impact on landing, imbalances in movements
-it can be used to improve technique
-assess injuries
-assess strengths and weaknesses in muscles
-for gait analysis
-to assess balance
-posture analysis

Question 5

What are wind tunnels?

Answer 5

Steel houses with a 4m wide fan that rotates up to 600rpm.

Question 6

Why would wind tunnels be used in sports?

Answer 6

F1 drivers or cyclists can use these to assess how air flows around them and look at what can be done to reduce air resistance.
