fatigue, soreness, and cramps

do lipids deplete

NO they’re just slow to be available

PCR depletion limits ability to replace ___, which results in fatigue

ATP

rapid breakdown of PCr and ATP cause

Pi

lactic acid comes from

anaerobic glycolysis

lactic acid is produced during

high intensity aerobic exercise

lactate can be shuttled to same/adjacent fiber or liver t/f

true

H+ accumulation causes

muscle acidosis

muscle acidosis limits

performance

ATP breaks down in ADP and Pi through a _____ reaction

hydrolysis

buffers help minimize

drop in pH after exercise

fatigue may inhibit Ca release from SR due, and this is bad because CA starts the

cascade that leads to the power stroke

excitiation-contraction coupling

action potential travels down motor neuron, ach is released at NMJ, muscle contraction

heat can ___ TTE (time to exhaustion)

shorten

heat forces the body to be more ____ ____

metabolically active (sweat needs to be produced to cool body down)

muscle soreness is caused by

breakdown of muscle by overloading muscle

DOMS

delayed onset muscle soreness

downhill running causes more pain due to

eccentric hamstring action

increased blood lactate concentration is associated with

fatigue

structural damge is indicidated by elevated

muscle enzymes in blood

damage in muscles leads to

hypertrophy

DOMS reduces

muscle force generation

EAMC

exercise associated muscle cramps

hyponatremia is caused by decreased

sodium in blood (bad!)

Fick principle

tissue O2 consumptioon can be calcualted based on

ventilation is typically not a limiting factor during exercise t/f
