S Electromyography (EMG) measurement of electrical potential
ofmuscular activation
S %MVC EMG signal normalized to a maximum
voluntarycontraction
S Kinematics describes motion without the causes of it
(displacement,velocity, acceleration)
S Kinetics describes motion and the causes of it (force, torque,
energy)S Force an influence that causes an object to undergo change
in
movement/direction/shape

Terminology
S Torque tendency of a force to rotate an object about an axisS
Energy (kinetic) Work needed to accelerate an object from rest to
a
given velocity
S Energy (potential) Work or energy of an object due to its
position ororientation
S Power Rate of work/energyS Stress Pressure exerted on an
object (force per unit area)S Hoop stress Stress exerted along the
circumference of a cylinder

Training Notes
SStimulus vs. Hypertrophy vs. PerformanceS What are we training
for?
S Create activation, then train compound exercisesS Goal
oriented training
S If our training goals involve high performance/heavy
weights,we should train accordingly
S Makes no sense to just do low load training

Summary
S GlutesS Active hip external rotator, extensor abductorS
Passive knee extensorS Role in knee and core stability
S Important in many athletic tasksS Powerful hip extension
S Train the glutesS Activation work first, followed by
power/strengthS Clamshell, monster walk, kettlebell swing, squat,
deadlift

Summary
S Developing athleticismS Big biceps or strong legs?S Hips used
in almost all athleticism; throwing/punching an
expression of hip power through upper limbs
S Whole body synergyS No such thing as isolation movementS Train
the way you use your bodyS Transfer of force/energy from one end of
body to otherS Magnitude of activation is rarely important timing,
motor
