Kinematic Chain Flashcards
What is a kinematic chain?
a sequence of events that produce performance
How is a kinematic chain started?
force occurring eg GRF or Muscular
Contributions to tennis serve velocity
order and magnitude of peak velocities at different joints
can be linear or angular
Contributions to tennis serve velocity (% racquet velocity)
Forearm 40%
Hand 30%
Upper arm 10%
Legs/Trunk 10-20%

What does each segment of the kinematic chain do?
produces force to add to towards the final velocity but also stabilises the next segment
What happens when a segment is lacking compared to the others / fails
performance drops
injury risk increases
How can performance be improved through the kinematic chain?
obtain maximal velocity
peak velocity is at impact/release
