|
concentric |
muscle shortens, lowest force generated, uses the most energy |
|
|
isometric |
muscle does not change in length, more force than concentric, less energy than concentric |
|
|
eccentric |
muscle lengthens, highest amount of force, lowest amount of energy |
|
|
isokinetic |
same motion, constant speed |
|
|
plyocentric |
jumping, pre stretch reflex, |
|
|
maximal force is generated at a joint angle that corresponds to .... |
maximal cross bridge interaction |
|
|
the greater the body mass the greater the... |
absolute strength |
|
|
relative strength |
maximal strength divided by body mass |
|
|
as speed of movement increases.... |
the force a muscle can generate decreases |
|
|
3 main components of strength related to speed of movement are... |
maximal strength, power, muscular endurance |
|
|
muscular strength |
the amount of force a muscle can produce in a single maximal effort (one repletion max) |
|
|
muscular endurance |
the ability to resist fatigue and sustain a given level of muscle tension for a given time |
|
|
muscular power |
the ability to overcome external resistance by developing a high rate of muscular action "speed strength" |
|
|
greater fast twitch muscle fibers= |
greater overall speed, greater fatiguibility and greater force producing capacity |
|
|
greater slow twitch muscle fibers= |
lower the force producing ability, slower overall speed, greater endurance |
|
|
men exhibit a greater degree of |
muscular hypertrophy |
|
|
development of maximal strength through |
hypertrophy of myofibrils |
