Document Summary
Why does high frequency fatigue occur cant generate action potentials or membrane potential decreases recovers quickly after the exercise. What is the cause of low frequency fatigue reduced calcium if calcium drops a small amount force drops a lot, long lasting fatigue. What can overcome both lff and hff caffeine. Is non-metabolic or metabolic fatigue more destructive and why non-metabolic because its permanently damaged the muscle tissue. Its caused by o2 free radicals, eccentric contraction, proteolytic enzymes. List the canges in twitch with respect to fatigue less force, decrease in max force development, increase in contraction and relaxation time. When and how does post titanic potentiation occurs at low frequencies and ft fibres, because of mlck phosphorylation of lc2. Why doesn"t potentiation occur in type i fibres mlcp is so fast. How much can atp demand increase from rest 200x. How long will our atp reserve last 2-3 sec.
