1. Muscles and Fiber Types

2. Types of Muscle Tissue Glycotic Muscle: Remembering Biology:
Mostly Fast Fibers
Low in myoglobin
Low in mitochondria
Contract quickly
Fatigue quickly
Remembering Biology:
What is the role of the mitochondria?
Why would its presence be limited in glycotic muscle?
Which type of muscle would have a higher capillary density?
Myoglobin stores oxygen
Mitochondria uses oxygen to produce ATP
Oxidative Muscle:
Mostly Slow Fibers
Lots of myoglobin
Lots of mitochondria
Contract slowly
Fatigue slowly

3. chicken analogy Chickens stand around all day long
Chicken legs are dark meat
Chickens have short burst of wing flapping
Chicken breasts are white meat

5. Data tends to show that fast twitch muscle can be changed to slow switch muscle trough endurance training.
