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.
