mTOR Part 2: Effect of Protein-feeding on mTOR Post-Exercise

The video explains the role of mTOR in cell processes, particularly in muscle growth. It highlights how exercise, especially resistance training, increases mTOR levels, which are further enhanced by protein intake. The importance of amino acids, especially branched-chain amino acids like leucine, in stimulating mTOR and muscle protein synthesis is discussed. The video emphasizes the need for a balanced intake of all amino acids for effective protein synthesis.

What is the primary focus of mTOR in exercise science?

• Calcium influx

• Muscle protein growth

• Cell differentiation

• Cell apoptosis

What happens to mTOR levels after resistance exercise?

• They decrease after 24 hours

• They increase significantly

• They remain unchanged

• They decrease immediately

Why is it beneficial to consume protein after exercise?

• To reduce glucose levels

• To decrease mTOR levels

• To enhance cell apoptosis

• To increase muscle protein synthesis

What is the role of insulin in muscle protein synthesis post-exercise?

• It decreases mTOR activity

• It has no effect

• It enhances mTOR activity

• It inhibits glucose uptake

Which amino acid is most effective in stimulating mTOR?

• Glutamine

• Leucine

• Isoleucine

• Valine

Why is it important to have all amino acids present for protein synthesis?

• To synthesize essential proteins

• To increase glucose levels

• To decrease mTOR levels

• To enhance cell apoptosis

What is the effect of eating a meal much later after exercise?

• It has less effect on muscle protein synthesis

• It maximizes mTOR levels

• It decreases glucose levels

• It enhances cell apoptosis
