1. TRAINING ANATOMY 1. Nerves – trigger message from brain
2. Fibers – long, thin hair like structures
that cause muscles to move
3. Blood vessels – provide oxygen and
energy to fibers
4. Connective Tissues
A. Tendons – connect muscle to bone
B. Ligaments – connect bone to bone
C. Cartilage – cushion between bones

2. 430 Anatomy (cont.) Three types of muscles in your body
Cardiac – Heart
2. Smooth – Organs
3. Skeletal - Movement

3. MUSCLES Body moves through “contractions”
Concentric – “work” phase, muscle
contracts & shortens
Eccentric – “rest” phase, muscle
releases & expands

4. Genetic Potential Inherit a set number and % of fibers
Fast Twitch (white) lack blood and oxygen
A. Used for quick, powerful activities
B. Not good for endurance
Slow Twitch (red) full of blood and oxygen
A. Used for endurance

5. Trapezius
Deltoids
Latissimus Dorsi
Pectorals
Flexors
Biceps / Triceps
Glutes
Abdominals
Abductor / Adductor
Hamstrings
Quadriceps
Gastrocnemius
