1

neural adaptations with anaerobic exercise

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

2

central adaptations with anaerobic exercise

increases when new exercises are being learned
most takes place in spinal cord

3

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

increases

4

physiological adaptations with anaerobic resistance exercise mitochondrial density

decreases

5

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

increases

6

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

increases

7

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

may increase

8

physiological adaptations with anaerobic resistance exercise body %body fat

decreases

9

physiological adaptations with anaerobic resistance exercise fat-free mass

increases

10

maximal strength and power increases of agonist muscles result from?

increase in recruitment, rate of firing, synchronization of firind

11

motor units are recruited in what order?

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

12

the size principle might not exist in ? becasue?

elite athletes, body learns to recruit more effectinly

13

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

muscle size

14

smaller muscles rely on?
large muscles rely on?

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

15

anaerobic training can ? firing rates of recruited motor units

enhance

16

neuromuscular junction

interface between the nerve and skeletal muscle

17

cross-educatio

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

18

bilateral deficit

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

19

sequence of protein synthesis involves

1. water uptake
2. noncontractile proteins
3. contractile protein synthesis

20

muscle hypertrophy takes longer than ? workouts

16

21

hyperplasia

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

22

what fiber type increases with resistance training

both, type II increase more

23

type IIx fiber type will change to type IIa because?

they change their ATPase becuase they are activated so much

24

factors of strength trained athletes

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
