Kinematics
|
describes motion. involves the study of space and time factors like acceleration and velocity
|
|
|
|
kinetics
|
concerned with the cause of motion. involves the study of forces (gravity or muscles)

|
|
|
|
what are kinetic variables?
|
mass, force, power, work, friction, pressure, energy, torque

|
|
Why is it believed that IRR allows for greater power output?
|
it allows partial recovery of Phosphocreatine levels and other energy substrates and the reversal of fatigue

|
PROM squats/quarter squats in the 8-15 rep range
|
|
|
|
what do successful olympic lifts result from?
|
power output rather than barbell trajectory
|
|
|
|
what can coaches aim to train for in the first pull of olympic movements?
|
maximum mechanical strength
what characteristics should coaches train for in the second pull? |
increase explosive strength of extensors around the hip, knee, and ankle
|
