|
Definition
Action of this muscle
Biceps femoris |
|
|
Term
|
Definition
- Axis of rotation (fulcrum) between the Effort (force) and resistance (load)
Example= seesaw |
|
|
Term
|
Definition
The resistance (load) between fulcrum (axis of rotation) and the effort (force)
Example= Wheelbarrow |
|
|
Term
|
Definition
Effort (force) is in between the axis of rotation (fulcrum) and the resistance (load)
- usually ofr large mvm's at rapid speeds and are the most common type in the body.
Example= shoulder abduction and elbow flextion w/ weights |

Anearobic Metabolism
-short duration exercise such as sprinting 100 meters
-system provides energy for muscle contraction for up to 15secs. |
|
|
Term
|
Definition
| This system represents the most rapidly available source of ATP for use by the muscle |
|
|
Term
|
Definition
energy system is a mojor supplier of ATP during high intensity, short duration activities
-sprinting 400-800m
-provide a person with 30-40secs of musc contraction |
|
|
Term
|
Definition
This system results in the formation of lactic acid which causes muscular fatigue.
- It only uses carbs (glycogen and glucose) |
|
|
Term
|
Definition
This system is used during predominately long duration exercise such as running a marathon
-provides energy through the oxidation of food
-will provide energy as long as there are nutrients to utilize |

Distributed thoughout muscle bell.
sends info to the nervous system
about muscle length and/or rate of change of length
controls posture and involutary mvm |
|
|
Term
|
Definition
-encapsulated in sensory receptors through the muscle tendons
-Very sensative to tension
-especially when from active muscle contraction.
-Transmits info about tension or the rate of change of tension within the muscle |
|
|
Term
|
Definition
| this contraction occurs when the tension developed by the muscle, while shortening or lengthening at a constant speed, is maximal over the full range of motion |
