29 Reasons

This parody (written by Greg Crowther) is sung to the tune of "29 Ways" (written by Willie Dixon and performed by Marc Cohn).


Lyrics

I got 29 reasons why muscles are not a bore.
I got 29 reasons why muscles are not a bore.
When applying for grants,
I can find about two or three more.

If you check out a standard lass,
Muscles are a third of her body mass.
I got 29 reasons why muscles are not a bore.
When applying for grants,
I can find about two or three more.

From cooking your food to sweeping the floor,
Muscles do a really wide range of chores.
You could be out shopping or starting to groove,
But muscles are behind your every move.
I got 29 reasons why muscles are not a bore.
When applying for grants,
I can find about two or three more.

When a muscle is used at a sporting event,
Its fluxes rise 5000 percent!
And if you're getting fit or you have a disease,
Muscle adaptation can be quantified with ease.
I got 29 reasons why muscles are not a bore.
When applying for grants,
I can find about two or three more.


Comments

This song presents a summary of reasons why skeletal muscles are interesting and important from a biological perspective. The lyrics are based on Chapter 1 of my doctoral dissertation, "An analysis of metabolic fluxes in contracting skeletal muscle."

Questions: (1) The song claims that a muscle's fluxes can rise 5000 percent during exercise. This would be equivalent to the new flux being how many times that of the old flux? (2) What specific metabolic flux is most likely to rise by this much? (3) When a person gets fit, what sorts of muscle adaptations can be "quantified with ease"? Answers: (1) 50. (2) Glycolysis, which is extremely limited at rest but can rise to very high rates during intense exercise. (3) Answers will vary. For example, one can track improvements in a function such as the amount of weight lifted or the time taken to run a mile (although these changes may not be attributable solely to changes within the muscles). One can also notice histological changes such as increased mitochondrial density and increased capillary density resulting from endurance training. Finally, strength training may simply increase the size of muscles.
