Which of the following are causes of muscle fatigue
|
|
ionic imbalances
|
|
|
lactic acid accumulation in muscle
|
|
|
decrease in ATP supply
|
|
|
too much calcium
|
Explanation:
Detailed explanation-1: -The exact causes of muscle fatigue are not fully known, although certain factors have been correlated with the decreased muscle contraction that occurs during fatigue. ATP is needed for normal muscle contraction, and as ATP reserves are reduced, muscle function may decline.
Detailed explanation-2: -Glycolysis converts glucose to pyruvate, water and NADH, producing two molecules of ATP. Excess pyruvate is converted to lactic acid which causes muscle fatigue.
Detailed explanation-3: -Addison’s disease. age. anaerobic infections. anemia. anxiety. botulism. cerebral palsy. chemotherapy. More items •12-Apr-2018
