|
Have high aerobic capacity but low power and are recruited primarily for endurance type activities such as jogging
|
Slow twitch muscle fibers
|
|
Are able to contract more quickly and genrate more force but fatigue relatively quickly
|
Fast twitch muscle fibers
|
|
The contracting muscle that initiates movement
|
Agonist
|
|
The opposing muscle
|
Antagonist
|
|
When muscles are not used they grow weaker and stiffen or shrink in size what is the shrinking called
|
Atrophy
|
|
When muscles are stimulated by an increased workload they grow stronger and muscle fibers experience
|
Hypertrophy
|
|
Exercise in which the muscle contracts but does not change length and little or no movement occurs
|
Static(isometric)exercise
|
|
Exercie in which the muscle contracts and shortens and movement occurs
|
Dynamic (isotonic) exercise
|
|
A muscle shortens as it overcomes resistance
|
Concentric contraction
|
|
Occurs when a muscle lengthens and contracts at the same time, gradually allowing a force to overcome the muscle
|
Eccentric contraction
|
|
A constant resistance is used throughout the range of motion
|
Constant resistence exercise
|
|
The force needed to move the weight is changed to provide a maximum load throughout the range of motion
|
Variable resistance exercise
|
|
The speed of movement is controlled, a type of dynamic exercise is..
|
Isokinetic
|
|
The most important principal of resistane training
|
Progressive overload
|
|
To stimulate muscle to overloaded or forced to work at a higher than normal effort
|
Progressive overload
