Q

smaller muscles rely on?

16
Q

neuromuscular junction

A

interface between the nerve and skeletal muscle

17
Q

cross-educatio

A

training only one lim can result in an increase in strength in the untrained limb

18
Q

bilateral deficit

A

the force produced when both limbs are contracting together is less than the sum of the forces they produce when contracting unilaterally

19
Q

sequence of protein synthesis involves

A
  1. water uptake
  2. noncontractile proteins
  3. contractile protein synthesis
20
Q

muscle hypertrophy takes longer than ? workouts

21
Q

hyperplasia

A

an increase in the number of muscle fibers via longitudinal fiber splitting as a response to high intensity resisitance training

22
Q

what fiber type increases with resistance training

A

both, type II increase more

23
Q

type IIx fiber type will change to type IIa because?

A

they change their ATPase becuase they are activated so much

24
Q

factors of strength trained athletes

A

increased angle of pennation which can accommodate greater protein deposition that allows greater increases in CSA.
greater fascicle length

25
anaerobic exercise can result in what to muscle and blood pH?
substantial reducations
26
how to increase buffering capacity
HIIT above lactate threshold
27
minimal essential strain
the threshold stimulus that initiates new bone formation
28
components of mechanical load that stimulate bone growth
magnituve of the load (intensity) rate (speed) direction of the forces reps
29
how to stimulate bone growth
use exercises that directly load particular regions of the skeleton structural exercises overload vary exercise selection
30
changes in tendon with anaerobic exercise
increase in collagen fibril more covalent cross-links more collagen and greater density of collagen
31
how to stimulate connective tissue adaptations for tendons ligaments and fascia
high intensity loading
32
how to stimulate connective tissue adaptations for cartilage
weight-bearing forces through complete range of motion, moderate aerobic exercise
33
acute anabolic hormonal responses to anaerorobic training
elevated levels of hormones such as test, growth, cortisol, catecholamines
34
chronic changes in the the acute hormonal response to anaerobic exercies
the acute hormonal response may improve
35
chronic changes in resting hormonal concentrations with anaerobic exercises
not very much change
36
hormone receptor changes with anaerobic exercises
AR(androgen receptor) interacts with test, resistance training can upregulate AR
37
acute anaerobic exercise cardiovasculare and respiratory responses
increased cardian output, stroke volume, heart rate, oxygen uptake, systolic blood pressure and blood flow to active muscles
38
chronic cardiovascular adaptations to anaerobic exercise
no change in resting HR | systolic and deastolic blood pressure decreased
