Types of Muscle Contractions
Isotonic
produce movement
Types of Isotonic Contractions
Types of Isotonic Contractions:
Concentric
muscle shortens
Types of Isotonic Contractions
Types of Isotonic Contractions:
Eccentric
muscle lengthens
Types of Muscle Contractions
Isometric
contractions in which muscle length does not change but muscle tension may increase greatly
(i.e. pushing against a wall)

Muscle Configurations
(7)
Circular
Triangular
Parallel
Unipennate
Bipennate
Multipennate
Fusiform
Types of Muscle Fuel
Phosphagen System
(ATP-PC System)
anaerobic
burns up very quickly
Types of Muscle Fuel
Glycolitic System
(glycogen-lactic acid)
anearobic
uses glycogen stored in the liver
results in muscle fatigue
Definition
Glycogen
muscle fuel component stored in the liver
Types of Muscle Fuel
Aerobic System
(Cellular Respiration)
uses fatty acids from fat, amino acids
sustained exercise
