fuel selection determination Flashcards
factors affecting fuel determination
intensity, duration, training status, diet, sex, environmental conditions
intense - sprinting example. describe what happens to power
highest in early stages
reduction as duration increases
what accumulates in intense ex
lactate, suggests glycolysis leading to lactate as major production pathway
what energy systems are used in intense ex
initially substrate level oxidation - pcr, glycolysis to lactate but contribution declines as duration increases
increased phos.oxidation but at the cost of total power generated
how long to fully restore max power?
requires recovery capacity to maximally utilise substrate-level phosphorylation pathways
what fuel sources used in endurance
carbs and fat support atp resynthesis
