1
Q

neural adaptations with anaerobic exercise

A

first to occur
increase in agonist muscle recruitment
a reduction in inhibitory mechanisms(GTO)

2
Q

central adaptations with anaerobic exercise

A

increases when new exercises are being learned

most takes place in spinal cord

3
Q

physiological adaptations with anaerobic resistance exercise fiber size, myofibrillar volume, cytoplasmic density, myosin heavy-chain protein

A

increases

4
Q

physiological adaptations with anaerobic resistance exercise mitochondrial density

A

decreases

5
Q

physiological adaptations with anaerobic resistance exercise creatine phosphokinase, myokinase, phosphofructolkinase, sodium-potassium ATPase

A

increases

6
Q

physiological adaptations with anaerobic resistance exercise stored ATP, Creatine phosphate, glycogen

A

increases

7
Q

physiological adaptations with anaerobic resistance exercise ligament, tendon, collagen and bone density strength

A

may increase

8
Q

physiological adaptations with anaerobic resistance exercise body %body fat

A

decreases

9
Q

physiological adaptations with anaerobic resistance exercise fat-free mass

A

increases

10
Q

maximal strength and power increases of agonist muscles result from?

A

increase in recruitment, rate of firing, synchronization of firind

11
Q

motor units are recruited in what order?

A

according to their recruitment thresholds and firing rates (size principle)

12
Q

the size principle might not exist in ? becasue?

A

elite athletes, body learns to recruit more effectinly

13
Q

the role of increasing firing rate (vs. recruitment) appears to be dependent on ?

A

muscle size

14
Q

smaller muscles rely on?

large muscles rely on?

A

small muscles: increased firing rate to enhance force production
large muscles: recruitment

15
Q

anaerobic training can ? firing rates of recruited motor units

A

enhance

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
