Study Notes
Types of Fatigue
- Central fatigue is related to the central nervous system (CNS), involving the brain and spinal cord.
- Peripheral fatigue affects the peripheral nervous system (PNS), involving the muscles and nerves outside the CNS.
Effects of Fatigue
- Fatigue affects the force-velocity and power-velocity relationships, altering the body's ability to produce force and velocity.
Central Fatigue
- The brain is the part of the body associated with central fatigue.
Peripheral Fatigue
- Peripheral fatigue is related to the muscles and peripheral nervous system, affecting muscle function and neural transmission.
