final SG Flashcards
(60 cards)
weight vs. strength training
fitness levels and appearance // strength and athletic performance
muscular strength
maximum force in a single effort (1 RM)
muscular endurance
perform repeatedly for an extended period
eccentric movement
muscle lengthens
concentric
muscle shortens
isometric movement
tension without movement (plank)
skeletal muscle
voluntary:
- slow twitch (long)
- fast twitch (explosive)
smooth and cardiac muscle
involuntary
endurance program
“toning”
lower weight, higher reps, shorter rests
hypertrophy program
muscle building
moderate weight, moderate reps, moderate rests
strength program
strength and power
heavy weight, low reps, long rests
major muscle groups (cross multiple joints)
chest, back, legs, shoulders
chest
pectoralis major
shoulders
deltoid
back
latissimus dorsi
legs –quads
- rectus femoris
- vastus intermedius (beneath rectus femoris)
- vastus lateralis (outer)
- vastus medialis (inner)
legs – hamstrings
- biceps femoris
- semitendinosus
- semimembranosus
arms
- triceps brachii
- biceps brachii
variable resistance machine
load changes throughout ROM to maximize weight displacement
pros to machines
back support; quick and easy; no spotter
cons to machines
limited availability, limited ROM, limited weight
kidney shaped wheel or cam
causes the distance between the pivot point and weight to change
fixed resistance equipment
pre-set pulley
free weights
constant resistance
*pros: cheaper, full ROM
*cons: requires spotter, more injury prone
