Hey single bout of resistance exercise training increases muscle protein synthesis by as much as _____% above resting levels

120-150

Which of the following factors does not contribute to the endurance exercise training induced increases in fat metabolism during exercise?

Increased fat storage in the liver

Which of the following endurance training adaptations does not result in lower lactate production in the contracting muscles?

Increased glycogen utilization

Which of the following endurance training adaptations assist in maintaining acid-base balance during exercise?

Increased mitochondrial volume in skeletal muscle

The enhanced capacity of the trained muscle to use fatty acids as a fuel results in

Increased uptake of fatty acids, decreased utilization of muscle glycogen, sparing of blood glucose

Endurance training has been shown to reduce the oxygen deficit in subjects performing a submaximal exercise. This is due to

Increases in the number of mitochondria and capillaries

Endurance exercise training results in an increase turnover of mitochondria in skeletal muscle. The process of removing old and damage mitochondria is called

Mitophagy

What two signaling molecules interact to directly activate mTOR?

Phosphatidic acid and Ras homologue enriched brain (Rheb)

In resting skeletal muscle fibers, Ras homologous enriched brain (Rheb) activation of mTOR is inhibited by ______

Tuberous sclerosis complex 2 (TSC2)
