Adaptations to Aerobic Training Flashcards
what is cardiorespiratory endurance. and how is it improved
ability to sustain prolonged dyamic exercise. its improved through multisystem adaptations
increasing max endurance capacity does what to vo2 max
increases
what does increases submaximal endurnace capacity do to HR
lower hr at same submaximal oexercise intensity
what are the mjajor CV changes
heart size, SV, HR, blood flow, blood volume, RBC volume
Heart size with trainin
increases heart mass and LV chamber size
modifications of contractile properties include what
sensitiitiy to calcium
changes in force-length relationship
increased power output
overload stimulates RNA content
physiological hypeertrophy
normal, both englarg. LV and heart
pathological hypertrophy
just one or the other enlarge. leads to dysfunction. heart failure. bad
can you icrease sv with training
yes
what else increases in regards to SV with exercise
plasma volue, edv, preload strethc, increased filling time, incresed lv mass, increased force of contraction
CV heart rate with psns and sns
psnsn increases at rest and decreased sns
submax hr info
decreases hr for same iven absolute intesity
max hr
no sig change w training
decreases with age
hr and sv interact to optimizw what
cardiac output
HR recovery info
faster with training to reflect cardiorespiratory fitness and efficientyc
is cardiac outpur affected at rest, submax, or max
litte to no change at rest or submax
increased a lt at max because of sv increases
what happens to capillaries during exercise
increases capillary to fiber ration to incease blood flow to active muscles
also decrease blood flow to inactive regions
blood volume is affected how
it is incereases to prevent a decrease in venous return when there is more blood in capillaries
adaptations to plasma and blood volume
increase plasma volume via increaseing plasma proteins and water and sodium retention. rbs is also increased. but decreased viscosity.
also , hct decreases even thought they both individually increase
Q to treadmill speed graph
mwahahahhahah
P pulmonary ventilation at submax and Max
Decreases at submax and increases at Max
Pulmonary diffusion at Submax and Max
Unchanged at rest and submax but increased at Max
A v 02 difference
Increases
Increases in PGC 1 alpha
Master switch for mitochondria
