lec 4 Flashcards
appropriate fitness test for older adults
1 RM or field tests like 30s chair stand or single arm curl
appropriate fitness test for known CVD, pulmonary and metabolic diseases
conservative approach
appropriate fitness test for children and adolescents
1 RM or field test
-supervised
what is flexibility
ability to move a joint through its complete, pain free ROM
static flexibility
total ROM at joint and extensibility of musculotendinous unit
dynamic flexibility
rate of torque or resistance developed during stretching throughout the ROM
ex: jete
active movement vs passive movement
active: joint going through ROM with help of other mm
passive: external force is applied to extend stretch
what do limitations to flexibility depend on
-joint capsule
-warm up
-muscle viscosity
-compliance/tightness of other tissues
why is flexibility important
preventing injuries, QOL etc
can you develop too much flexibility
hypermobility: increased ROM beyond normal, acceptable values
direct assessment test
-measures amount of joint rotation in degrees using goniometer, flexometer, or incinometer
-high agreement between ROM measures by radiographs and goniometers and incinometers
indirect assessment test
-linear measurement of distances between segments
ex: sit and reach
qualitative assessment approaches
thomas test
obers test
what is balance
ability to keep bodys COG within base of support when one is maintaining a static position, performing voluntary movements, or reacting to external disturbances
static balance
maintaining COG in base of support while sitting or standing
dynamic balance
maintaining upright position or balances position while in motion
reactive balance
compensating or recovering from other disturbances
functional balance
what systems interact to maintain balance
visual
somatosensory aka proprioception
vestibular
visual system - balance
provides info about bodys loc in environment
somatosensory system - balance
provides info about position and movement of body parts
vestibular system - balance
provides info about head position in relation to gravity
assessment test for static balance
romberg test, unipedal stance test
assessment test for dynamic balance
functional reach test, star excursion balance test
single task vs multitask assessment
single: standing only
multi: standing while performing other motor or cognitive task
gait velocity test
indirect, dynamic measure of balance while walking
-amount of time to walk a set distance is measured
test batteries
includes multiple tests
-assesses static and dynamic
-ex: berg balance scale
