Week 5 - Metabolic Adaptations to Exercise Training Flashcards
what hormones are involved in exercise response?
norepinephrine, epinephrine, growth hormone, adrenocorticotrophic hormone
what happens hormonal response when exercising?
increase
what effect does endurance training have on rate of muscle glycogen and blood glucose utilisation?
it decreases the rate of both
what happens GLUT-4 during exercise?
its translocation decreases
how does endurance training effect glycogen reserves in muscle and liver?
it increases them
what effect does endurance training have on the oxidation of lipids?
it increases the capacity of lipid oxidation
release of fatty acids
fat storage
glycogen sparing effect
lower RER values
name 3 key glycolytic enzymes
glycogen phosphorylase, phosphofructokinase, lactate dehydrogenase
what effect does glycogen phosphorylase have on exercise?
breaks down glycogen quickly - energy source
what effect does phosphofructokinase have on exercise?
its activity increases, more ATP produced
what effect does LDH have on exercise?
endurance training reduces activity, decrease in lactate, increase in pyruvate
strength and sprint training has opposite effect, increase of LDH
what happens mitochondria with increased aerobic endurance training?
they increase in concentration
what metabolism is favoured in endurance trained people?
lipid
what metabolism is favoured in high intensity individuals? (not resistance training)
carbohydrate
what is maximal oxygen uptake?
VO2 max
what happens VO2max with training?
it increases
