Homeostatic imbalances of muscle Flashcards
What are muscle cramps?
involuntary muscle contraction
Common causes of skeletal muscle cramps:
dehydration, mineral defincies, fatigue
common causes of smooth muscle cramps?
Mentraution and gastroenteritis
Define fatigue
What determines how long fatigue last?
decline in a muscle fibers force generation capacity
The size of the muslce group determine how long fatigue will last
Central fatigue
-central nervous system related
-failure of CNS to send signals to muscle
-WANT to do something
Peripheral faitigue
motor neuron tranmition or motor neuron junction issue
Metabolic fatiue
- Exhaustion hypothesis (running out of substrate)
2.accumilation hypothesis (increased H+ release)
Fibromylagia
widespread pain and increased repsonse to pain and pressure. Menatal health issues too go hand in hand with this.
Cause is unknown but most likely it is caused by CNS
Delayed onset muscle soreness (DOMS)
pain felt in skeletal muscle sevral hours/days after unfamiliar or super intense workout. peaks 24-72 hours after workout
Rhabdomyolysis
rapid degeneration of skeletal muscle due to extensive injury which releases breakdown products into blood stream which harms the KIDNEYS
common causes of Rhabdo
excessiv exercise and/or dehydration
common symptoms of Rhamdo
muscle pain, swelling, dark urine, cardiac arymias
