endurance exercise Flashcards
what diets best for endurance exercise
high carb
what limits endurance ec
reduced glycogen availability, such as a lower rate of ATP synthesis in fat oxidation and inhibition of calcium handling
what inhibits ca2+ release and function in muscle contrcation
the products of atp breakdown and synthesis (Pi and H+)
what does the exercise intensity and duration determine
contribution of fat and carbs
primary fuel in most sports
carbs and glycogen
what happens when there’s a reduction of glycogen
associated with fatigue in prolonged exercise
what increases the release of glycogen
increased epinephrine, glucagon
decreased insulin
what increases glycogen breakdwon
increase in glucose uptake
by glut4 translocation
what decreases fat oxidation
decreased plasma FA availability/adipose tissue blood flow/HSL and mitochondrial fat uptake
what metabolism fuel does endurance exercise rely on
fatty acids and glucose and IMTG glycogen in muscles
whats blood fuels
glucose and fat
