8 define transient hypertrophy and explain how it

This preview shows page 2 - 4 out of 5 pages.

8. Define transient hypertrophy and explain how it occurs. a. Increased muscle size that develops during and immediately following a single exercise bout b. Occurs b/c fluid accumulates in the interstitial and intracellular spaces of the muscle that comes from blood plasma 9. Define chronic hypertrophy. a. An increase in muscle size that occurs with long term resistance training b. Actual structural changes in the muscle 10. What is the difference between hypertrophy and hyperplasia? a. Hypertrophy= increase in the size of existing individual muscle fibers b. Hyperplasia= increase in the number of muscle fibers 11. When looking at the whole muscle, how could you explain hypertrophy (i.e., what is accounting for the larger size of the muscle)? a. More myofibrils b. More actin and myosin filaments c. More sarcoplasm d. More connective tissue 12. How is protein synthesis involved with muscle hypertrophy? a. Protein synthesis decreases during exercise b. Protein synthesis increases after exercise c. taking carb and protein supplement after exercise creates a more positive nitrogen balance which facilitates protein synthesis and maximizes the muscles adaptive response to resistance exercise 13. Does nutrition have an effect on this? How? a. Yes (see above) 14. What hormone(s) have an effect on this? a. testosterone

15. Describe the current thought on how hyperplasia occurs. a. Muscle fibers are able to split in half w/ intense exercise weight training b. Each half then increases to the size of the parent fiber 16. How might satellite cells contribute to hyperplasia? a. May generate new skeletal muscle fibers b. Activated by stretch injury c. After activation, cells proliferate, migrate and fuse 17. Does muscle fiber hyperplasia occur in humans with exercise training?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
