cooper fitness PT cert Flashcards
concentric contractions
muscle shortens as it generates force to overcome gravity
average oxygen consumption at rest
3.5 ml/kg/mm
VO2 max =
max volume of oxygen the body can use
vo2 max represents?
highest level of oxygen consumption measured during maximal exercise text - expressed units of mg/kg/mm
vo2 max field tests
1 mile walk, 1.5 run, 12 min run
vo2 is a product of what 2 components?
Qx a-v o2 difference
bodies ability to utilize oxygen is based on?
hearts ability to pump blood, cells ability to remove oxygen
what carries blood
viens, arteries
a-v02 difference = ?
the difference in amount of oxygen between arteries and veins
coronary artery blockage is due to
plaque accumulation, plaque rupture, clot
what is CAD
coronary artery disease - buildup of fatty plaque inside coronary artery
blood flow through coronary arteries supplies?
heart (myocardium) with oxygen
4 types of cardiovascualr disease
CAD, cerebrovascular, chronic heart failure, perpheral artery disease
leading cause of death in US
cardiovascualr disease - lifestyle related
motor related components
coordination, agility power, balance, speed, accuracy
health related components
dynamics strength, absolute strength, flexibility, body comp
cardiac output =?
heart rate x stroke volume – amount of blood pumped by heart per minute
does stroke volume increase with exercise
yes
does HR increase with exercise
yes
avg adult resting cardiac output =
5L per minute
most resting blood flow goes
to internal organs viscera
blood is shunted during exercise from
internal organs to skeletal muscles
physical fitness
ability to perform daily tasks with vigor and alertness without undue fatigue
stroke volume =
amount of blood pumped by heart per beat
aerobic training =
increase maximal stroke volume for increased maximal cardia output
Does max HR increase as a result of exercise
no - decreases
component specifi goal setting guidelines for absolute strength
universal bench press 1RM | ratio pounds pressed/body weight
how dong does it take for significant change in absolute strength
8 weeks
what is the realistic improvement expected for absolute strenth in 8 weeks
10-15%
diasolic pressure =
blood through arteries at rest
systolic pressure =
blood through arteries while heart is contracting
BP =
force that moves blood through vessels
norms indicate?
relations to others similar in height, weight, age, gender ..
current fitness category refers to?
actual fitness level on fitness test scores
goal fitness category =
standard of fitness one hopes to achieve
goal raw scores =
desired fitness level in terms of time, distance, # of reps _
goal setting time for cardio improvement
12 weeks
gaol setting time for flexibility improvement
8 weeks
goal setting time for strength improvement
8 weeks
goal setting time for body composition improvement
12-16 weeks
signs and symptoms of exercise related injuries
swelling, dislocation, local fever, point tenderness, pain on movement, decreased ROM
symptom
something you can feel
sign
something you can see
hypertenstion is a major risk factor for
CVD, kidney disease
why would someone not have a target HR?
beta blockers
lack of duty =
omission (failing to do what should have been done) commission (doing what should not have been done)
absolute contraindication
unstable angina
cooper resting BP cutoff
160/100
contraindications
serious medical conditions where risk outweigh benefit
cartilege
avascular - lacking blood vessels
tendons
connect bone to muscle
ligaments
connect bone to bone
bursa sacks are found
in joints
high risk category for ACSM
signs/symptoms of CVD, pulmonary or metabolic disease
moderate risk categories for ACSM
asymptomatic with 2 or more risk factors
physical fitness profile examines?
current cardio, strengh, flexibility, body compostion
fitness profile is created by ?
identifying current fitness categories, setting goals and times to achieve
using normalative data, goal setting category should be set no higher than
one category above
is it better to set goal too easy or too hard
too easy
ideal goal should be
realistic and challenging
adaptions are
beneficial physiological changes that occur in response to exercise and training
common exercise related injuries
sprain, fracture, stress fracture, bruises, dislocation, PF, bursitits, patellofemeral pain, tendonitis
body acclimates to cold weather training how?
increased resting metaboilc rate, keeps blood near core and away from skin
2 major cold weather injuries
frostbite, hypothermia
fastest way to dissipate heat in heat-related injury
cold water - 26 x faster than cold air
stretch latissimus dorsi
shoulder flexion
stretch gastrocnemius
ankle dorsiflexion and knee extension
stretch hamstring
hip flexion and knee extension
stretch quad
knee flexion with hip extension - rectus femoris is a 2 joint muscle
stretch gluteus maximus
hip flexion
PNF proprioceptive neuromuscular facilitiation
stretching that combines isometic contraction held 6 sec with static stretch 10-30 sec
3 heat related injuries
heat cramps, exaustions, stroke,
profuse sweating in exercise is a good time for?
sport drink
sport drinks contain
water, sugar, salt (electrolytes)
what interferes with evaperation of sweat?
high humidity
2 types of static stretching
