Muscle Training and guidelines Flashcards
How often should you train to lower your cardiovascular risk?
5 days/wk - 30 minutes
What kind of training is needed to increase muscle strength, endurance or muscle mass and for how long?
Resistance training - 2 to 3 days a week
What is hyperplasia?
increase number of fibers/cells
Dynamic muscle strength improvements are greater when what kind of dynamic actions are included?
eccentric
resistance training includes what?
-dynamic exercise with concentric and eccentric actions
Eccentric contraction produces what?
greater force per unit area
What type of contraction is less metabolically demanding but produces greater hypertrophy?
eccentric
Define strength and the units affiliated with it
the ability to resist strain and stress; force or torque
Define power
rate of performing work; force per unit time
Work = ?
work = force x distance
power = ?
power = work/time
define muscle endurance
the ability to continue work over time
plyometrics mobilize what characteristic of skeletal muscle?
inherent stretch/recoil
What type of training overloads the muscle to provide a rapid stretch (eccentric) immediately prior to concentric contraction?
plyometrics
define neuromuscular fatigue
decline in muscle tension (force) capacity with repeated stimulation
muscle fibers experiencing oxygen depletion, increase in hydrogen, and depletion of PCr and ATP storage is an effect of what?
muscle fiber fatigue
When does DOMS generally occur?
24-48 hours after strenuous exercise
