Physical exam Flashcards
Deadlift joint actions
Hip and knee extension
Deadlift working muscles
Quadriceps
Gluteus maximus
Hamstrings
- biceps femoris long head (outside)
- semitendinosis (middle)
- semimembranosis (inside)
Deadlift stabilising muscles
erector spinate
rectus abdominals
transverse abdominals
external obliques
trapezius
rhomboids
grip muscles
- wrist finger flexors and extenders
Deadlift coaching points
- Shoe laces under bar
- even distance hands
- neutral spine - eyes focused few feet ahead
- brace before lift (engage muscles to create rigid stable foundation)
- all movements occur at the hips and knees
- breathe out when coming up or hold breath
- push the floor away
- keep arms straight and shoulders back
Deadlift applications
perfect the deadlift = safely lift thing in life
a stepping stone to other exercises like stiff leged deadlifts and bent over rows
Deadlift regression
blocks - limit range and bring bar closer
wraps - increase grip strength
dumbbells instead of bar
Deadlift progression
Increase the load
Chains - increase resistance at top as they dangle
stand on blocks - make bar further away
Bands - adds resistance to upward phase makes lockout phase harder
Stiff legged deadlift joint action
Hip flexion
Stiff legged deadlift working muscles
Gluteus maximus
Hamstrings
- bicep fermoris long head ( outside)
- semitendinosis
- semimembranosis (inside)
Stiff legged deadlift stabilising muscles
erector spinate
rectus abdominals
transverse abdominals
external obliques
trapezius
rhomboids
grip muscles
- wrist finger flexors and extenders
Stiff legged deadlift coaching points
deadlift into starting position
neutral spine, gaze few feet ahaed
slight bend in the knees
all movement at hips - push hips back
breathe out on way up
no lumbar flexion at lowest point
keep bar close to body throughout
Stiff legged deadlift applications
Helps with hamstring injury prevention (make stronger and longer)
helps with hip extensor tasks like kicking in kickboxing or splits in gymnastics
hinge movement cause no knee involved
Stiff legged deadlift regression
blocks - limit range
dumbbells instead of bar
decrease load
use the wall - tik tok thing
Stiff legged deadlift progression
increase load - chains, bands
blocks - increase range
Back squat joints
hip and knee flexion
Back squat working muscles
quadriceps
gluteus maximus
adductors
Back squat stabilizing muscles
Hamstrings
erector spinate
rectus abdominals
external obliques
transvers abdominus
Back squat coaching points
- Hands equal width on bar
- high bar = upper traps = quad dominant
- low bar = posterior deltoids = glutes
- Feet forward - prevents internal rotation of femur and keeps knee inline
- hip, knee and ankle aligned not valgus
- neutral spine
- brace before lift
- all movement in knee and hip
- no butt wink at lowest point
- butt wink shows lowest point so can work in that range
- breathe out on way up
- push the floor away
Back squat application
hip and knee extension essential in many tasks
vertically jumping
accelerating forwards
heavy loads can stimulate motor units
can be varied depending on what muscle wants working
have heavier load than front squat
Back squat regression
lower load
lower range - shallower squat
back squat progression
increase load - bands, chains increase resistance
increase range by squatting deeper
increase speed, explode from bottom of squat if working jumping for example
Front Squat Joint actions
Hip and knee extention
Front Squat used muscles
Quadriceps
Gluteus maximus
Adductors
Front Squat stabilising muscles
Hamstrings
Erector spinate
rectus abdominals
external obliques
transverse abdominals
