Flashcards in Fat and Carbohydrate: Exercise Physiology Deck (11):
1

A lot of "training" involves becoming better at ____________.

breaking down fatty acids

2

Six amino acids can be ___________.

metabolized to burn fuel (alanine is just pyruvate with an amino group)

3

When exercise begins, _________ is the primary fuel. With sustained low-intensity exercise, _________ predominates as the fuel source. As you progressively increase in intensity, ___________ and then _________ occur.

glycolysis; fat oxidation; glucose oxidation (TCA); lactic acid production

4

_____________ have been shown to have lower CVD risk than thin people who are unfit.

Obese people who are fit

5

Low glycogen stores have been shown to lead to what effects on exercise?

Decreased duration and intensity

6

Catecholamines phosphorylate what hormone that leads to release of fatty acids?

Hormone-sensitive lipase

7

One of the most consistent phenomena noticed with training is _____________.

that those who train produce lower lactate levels with the same expenditure and rely more on lipolysis and less on glycogenolysis

8

Training has been shown to increase levels of ___________ of skeletal muscle that lead to increased efflux of lactic acid.

metacarboxylates

9

During exercise, about ______ percent of glucose comes from lactate (via gluconeogenesis).

30

10

Six amino acids can be metabolized by muscle: _____________.

aspartate, glutamate, alanine, and the branched chain

11

As fat oxidation decreases, ________ increases.

lactate production
