Chapter 4 Flashcards
Muscular strength and endurance training goals focus on
Muscular endurance
Muscular strength
Muscular size/definition/hypertrophy
Muscular power
What is hypertrophy
What is it determined by
Increase in the number of myofibrils and the size of muscle fibers
Gender, genetics and training program
What does inactivity do
Atrophy
Reverses the process
Slow twitch fibers are:
Fatigue resistant
Dont contract as rapidly and forcefully as FT
Geared towards low intensity/endurance training
Fast twitch fibers are:
Contract rapidly and forcefully
Fatigue more quickly than ST
Produce greater force
Geared towards more strength development/training
Program variables that are manipulated to induce change/adaptation are
Muscle action
Load/Intensity
Volume
Exercise order and growth hormone effect
Exercise velocity
Frequency
What are the 3 different types of muscle action
What is the accronym
Concentric
Eccentric
Isometric
CEI
What are the two main types of strength training exercises
Static
Dynamic
Static exercise is also know as…
What occurs in this exercise
Isometric
Muscle contraction without a change in the length of muscle
Dynmaic exercise is also know as…
Isotonic
Muscle contraction with a change in the length of the muscle
Isotonic concentric contraction is when
Muscle applies force as it shortens and growth hormone impact
Isotonic eccentric contraction is when
Muscle applies force as it lengthens
When do untrained invidiuals experience strength gains
With 12 RM
When do trained individuals experience optimal strength gains
8 RM
What is the most critical factor in RM
Load and volume interaction
