L5 Flashcards
1
Q
explain the initial strength increase seen in training
A
the initial strength training is due to neuromuscular adaptations primarily to neural adaptations not increased muscle size - coordination of agonist (more efficient) /antagonist (stabilization)
2
Q
when talking about fatigue what occurs during sustained MVC
A
- decrease in force, synchronization and firing rate
3
Q
when talking about fatigue what occurs during sustained submaximal contraction
A
- increase in recruitment to maintain force
- increase in rate coding to maintain force
eventually - reduction in conduction velocity and increased duration of MUAP
- increased duration of twitch
- lower force
4
Q
explain the adaptive measures of the system to fatigue
A
- rate of motor unit firing slowly declines
increase in twitch relaxation time
5
Q
does rate coding or recruitment occur first
A
both occur at the same time to a certain degree
6
Q
what is an advantage to muscle wisdom
A
due to the elongation of twitch MU can summate at lower frequencies
7
Q
Can produce ____ force with ___ MU activity in eccentric contractions
A
more, less
8
Q
A
