Muscular Function Flashcards
Dynamic muscle actions Eccentric force (tension) generated as muscle shortens or lengthens?
Lengthens
Dynamic muscle actions
In concentric force (tension) generated as muscle shortens or lengthens?
Shortens
Static muscle actions Isometric force (tension) generated with no noticeable muscle lengthening or shortening
True
Eccentric
Lengthening
Concentric
Shortening
Maturation- strength increases differently during maturation in boys and girls. Males strength is greater.
True
Ageing muscle strength decreases with age
True
Long term adaptations of resistance training can modify normal ageing loss of muscle mass
True
What is plyometric training?
Exercises based around having muscles exert maximum force in as short a time as possible. Goal of increasing both speed and power
Movement types
Static
-isometric
Dynamic
- concentric
- eccentric
True
What does isokinetic mean?
Constant speed
What is power?
Force x velocity
Fibre orientations
Pennate (uni & bi)
Non-pennate (parallel & fusiform)
True
Physical activity
Endurance training (marathon running, endurance cycling)
Response/adaptation
Minimal CSA change, minimal strength change
True
Physical activity
Resistance training (weight training, sprint training)
Response/adaptation
Increase muscle CSA, increase in strength
True
