Lecture 29

Question 1

neural adaptations are highly specific to …. and what does this mean

Answer 1

highly specific to training, you can train one muscle and get very little transfer over to the other muscle

Question 2

neural adaptations to exercise result in increased agonist activation via

Answer 2

• decreased neural inhibitory reflexes
• increased motor unit recruitment
• increased unit firing frequency

Question 3

neural adaptations to exercise results in modifications to what

Answer 3

modifications to stretch reflex and golgi tenton organ reflex

Question 4

stretch reflex primes muscles to what

Answer 4

to increase force power output

Question 5

golgi tendon organ does what to force output

Answer 5

decreases force output

Question 6

what is plyometrics and what does it use

Answer 6

high explosive exercise
- use stretch shortening cycle

Question 7

the use of the stretch shortening cycling in plyometrics increases your ability to

Answer 7

increases ability to tolerate high stretch loads

Question 8

plyometrics increases muscle ….

Answer 8

muscle power output

Question 9

how does plyometrics increase muscle power output

Answer 9

uses stored elastic energy and stretch reflex

Question 10

what are the neuromuscular adaptations to high intensity training (jim says this is important)

Answer 10

increased max power

increased muscle strength

increased size (hypertrophy)

selective hypertrophy type II

change in type of myosin

increased neural adaptation (RFD)

increased Na+ K+ ATPase activity

Question 11

what is RFD

Answer 11

rate of force development

Question 12

what are the metabolic adaptations to high intensity training (jim says this is important)

Answer 12

increases ATP and PC stores

increased creatine kinase activity

increased ATPase activity

increased PFK activity

increased buffering capacity

Question 13

what is another adaptation to short duration, high intensity training and why

Answer 13

increased efficiency of movement

• neural adaptation = motor learning

Question 14

what is the psychophysical adaptations to short duration, high intensity training

Answer 14

increased pain tolerance

increased motivation ?

Question 15

High intensity interval training (HIIT) stimulates all energy systems and huge array of local and systemic adaptations, what does this mean in terms of cellular stress

Answer 15

intense cellular metabolic and mechanical stress

Question 16

High intensity interval training (HIIT) can stimulate fat oxidative capacity and aerobic power as effectively as what

Answer 16

as much larger volume of regular aerobic training

Question 17

High intensity interval training (HIIT) stimulates high vascular shear stress and /…..

Answer 17

and cardiac load

Question 18

interval training increases reliance on ATP supply ….. (also when)

Answer 18

increased reliance on ATP supply aerobically (so less anaerobic demand)
- during recovery periods
- also at a given work rate

Question 19

a benefit to interval training is that allows for simultaneous

Answer 19

simultaneously maximal contribution of all energy systems

Question 20

much aerobic adaptation occurs when in interval training

Answer 20

occurs within “anaerobic” training drills

Question 21

interval training can develop what types of power

Answer 21

aerobic and anaerobic power

Question 22

what are the absolute gains of strength training like in older adults and why

Answer 22

less absolute strength gains
- less cell signalling
- local acute inflammatory response

Question 23

what are the relative gains of strength training like in older adults and why

Answer 23

same relative % gains
