|
eccentric contraction
|
entails lengthening of the muscle (usually when a weight is lowered)
|
|
|
concentric concentration
|
involves shortening of the muscle, which moves the residence
|
|
|
isometric exercise
|
the muscle is contracting, but there is no shortening or lengthening of the muscle, and the power output is equal to the residence (ex: planks, wall sits, pushing a wall)
|
|
|
isotonic exercise
|
an activity that combines muscle contraction and repeated movement. (ex: push-ups, sit-ups, squats)
|
|
|
bone
|
a rigid lever, which allows joint motion to occur when the attached muscles act
|
|
|
ligaments
|
a tough inelastic connective tissue, which connects bone to bone
|
|
|
tendon
|
a similar connective tissue connecting muscle to bone
|
|
|
muscle
|
elastic contractile tissue connected by tendons to bones which provide the means for joint motion to occur
|
|
|
agonist
|
the muscle or muscle group, which contracts to cause a joint motion. also know as prime movers
|
|
|
antagonist
|
the muscle or muscle group, which extends as the agonist contracts to allow joint motion
|
|
|
spot reduction
|
the idea that if you work a specific muscle group you will decrease the amount of fat in that area ( ex: abdominal exercise is an effort to lose weight in their stomach area)
