- Stretch Reflex
- a • Formation of cross bridges between actin and myosin filaments.
• Reduction in distance between z-lines or sarcomere "power stroke"
• ATP is required for muscle contraction
o Myosin ATPase breaks down ATP as fiber
- b o Dynamic constant external resistance

- d delays impulse by 1/10 of second, allowing atria to contract before ventricles
- e • Quickly stretched muscle
• Initiate immediate contraction
• Due to being stretched

5 True/False Questions
force velocity curve → stabilizes and supports components of skeletal muscle
Surrounds muscle at each organization level.
Central Nervous System → consists of the brain and spinal cord
Three Parts to the structure of a Neuron: → Cell Body, Dendrites, Axon
Purkinje fibers → rapidly spreads impulse to contract throughout ventricles
Adaptations due to weight training → Increased cardiac output during endurance activity
Increased oxygen delivery to skeletal muscle
Increased endurance performance
