Lecture 1 Flashcards
What kind of stretching is proven to yield the most significant results and longterm changes, especially in patients with contractures
low load long duration
What does the creep and stress relaxation curve tell us about stretching
You can only hold a stretch so long before you start to see diminished returns
Stretching contraindications
bony blocks
non-union fracture
acute inflammation/infection
sharp/acute pain with elongation
hematoma or tissue trauma
hypermobiliy
hypomobility that provides stability
Muscle __________ represents a single burst of energy of high intensity activity or repeated bursts of less intense energy
Power
With isokinetic exercise, what is constant?
the speed
What is the Holten Curve used for?
Used to calculate someone’s 1RM or calculate how many reps theyd do at a different weight based on their 1RM
What causes acute muscle soreness?
How is it eased?
decreased bloowflow, ischemia, increased metabolites
Noxious stimuli that irritates free nerve endings
eased with low intensity exercise
What is Delayed Onset Muscle Soreness?
How can it maybe be prevented?
caused by unaccostumed vigorous resistance exercise
microtrauma to myofibrils and other muscle stuff
prevented (maybe) by warm up, and stretching, and concentrics before eccentric exercise
What are the 3 aspects of postural stability
passive- bones and ligaments
active- muscles
neural control
transverse abdominus, internal oblique, multifidus, and deep rotators provide what kind of function at the trunk
Deep/segmental (closer to axis of motion)
Rectus abdominus, external obliques, erector spinae, and illiopsoas provide what kind of function at the trunk
Global (farther from axis)
What is stretch weakness?
Muscles kept in a stretched position tend to be weak due to a shift in the length tension curve
What is tight weakness?
Muscles habitually kept in a shortened position tend to lose their elasticity and test strong onl yin shorted position, are weak when lengthened
How does the normal plumbline of posture travel?
Through ear and glenohumeral joint
through cervical vertebrae
through lumbar vertebrae
posterior to hip joint
through greater trochanter
anterior to knee joint
Anterior to lateral mal
What kind of posture is associated with anterior pelvic tilt, hip flexion, and an increased lumbosacral angle
Lordotic posture
