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

A

16

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
Q

anaerobic exercise can result in what to muscle and blood pH?

A

substantial reducations

26
Q

how to increase buffering capacity

A

HIIT above lactate threshold

27
Q

minimal essential strain

A

the threshold stimulus that initiates new bone formation

28
Q

components of mechanical load that stimulate bone growth

A

magnituve of the load (intensity)
rate (speed)
direction of the forces
reps

29
Q

how to stimulate bone growth

A

use exercises that directly load particular regions of the skeleton
structural exercises
overload
vary exercise selection

30
Q

changes in tendon with anaerobic exercise

A

increase in collagen fibril
more covalent cross-links
more collagen and greater density of collagen

31
Q

how to stimulate connective tissue adaptations for tendons ligaments and fascia

A

high intensity loading

32
Q

how to stimulate connective tissue adaptations for cartilage

A

weight-bearing forces through complete range of motion, moderate aerobic exercise

33
Q

acute anabolic hormonal responses to anaerorobic training

A

elevated levels of hormones such as test, growth, cortisol, catecholamines

34
Q

chronic changes in the the acute hormonal response to anaerobic exercies

A

the acute hormonal response may improve

35
Q

chronic changes in resting hormonal concentrations with anaerobic exercises

A

not very much change

36
Q

hormone receptor changes with anaerobic exercises

A

AR(androgen receptor) interacts with test, resistance training can upregulate AR

37
Q

acute anaerobic exercise cardiovasculare and respiratory responses

A

increased cardian output, stroke volume, heart rate, oxygen uptake, systolic blood pressure and blood flow to active muscles

38
Q

chronic cardiovascular adaptations to anaerobic exercise

A

no change in resting HR

systolic and deastolic blood pressure decreased
