_____ decrease the viscosity of muscle
Answers
Answer:
The relationship between water activity, viscosity and stiffness is discussed. It is concluded that the three parameters vary cyclically and that when water activity decreases (sarcomere shortening, cross-bridge attachment) viscosity and stiffness increase.
Warming up decreases the viscosity of muscles
Explanation:
Muscle viscosity describes the effectiveness and efficiency of a muscle to do work. It is the rate at which your muscles perform demands. Secretion of synovial fluid and lubrication of the muscle inhibit the muscle from reacting too quickly by slowing the contraction; this prevents tearing as the muscle seeks to lift the load.
Warming up decreases the viscosity of muscles. It is find out that if a previously inactive muscle is stimulated repeatedly, the first few contractions are often small and irregular and relaxation is incomplete. But once the contractions become stronger relaxation is complete. It takes place due to decrease in the viscosity of muscles. This leads to faster and efficient rate of muscular contraction and relaxation. It also reduces the occurrence of injury or wear and tear of muscles and ligaments.
Muscle tears occur more frequently when individuals attempt to lift heavy loads and perform strenuous activities without a proper warm-up and stretching. An improper warm-up may not allow sufficient time for secretion or lubrication of the muscles- which may result in injury.
Also, increasing fluid intake and use of guaifenesin (an expectorant) will decrease mucous viscosity.
Antihistamines will increase mucous viscosity.
