"Marathon Mouse" Keeps On Running - Part C

You are going to read the end of the article "Marathon Mouse".

Some sentences are not complete. You are given all the necessary words but they are in the wrong order. Once you have re-ordered the end of the sentence you must type the sentence in the space provided. Begin as shown. Watch your spelling, the punctuation and capital letters!

Ex:

" Their resistance to weight gain is ...... exercise/ to/ not/ due / simply/ increased/ "

You should type:

"Their resistance to weight gain is not simply due to increased exercise. "

Now you try:

1. “Significantly, the increased number of fat-burning muscle fibers appears by itself to be protective against a high fat diet,” he said. “And that's important because it indicates that the presence of more mitochondria in the muscles of these animals probably results ....... some / heat / in / release / energy / the / of / as .” (Start typing from "it indicates.. ")


2. “This leads me to believe that long distance runners, for example, possess a level of protection against weight gain even when they are not exercising," said Evans. "So, in a sense, they have built a kind of metabolic “shield” ....... them / gaining / that / from / weight / keeps.” (Start typing from "they have built...")

 


3. Also, when normal mice received the PPAR-delta-enhancing drug, they showed a virtually identical protection against weight gain, said Evans. The genetically altered mice also had lower levels of intramuscular triglycerides, he said, which are often ....... and / insulin / associated / obese / resistance / people / diabetes / in / with. (Start typing from "which are often..")


4. The marathon mice lived up to their nickname when Evans and his colleagues tested the animals' endurance on a treadmill. When they placed these mice, which had never been run before, on a treadmill, the astonishing result was that the mice could....... that / twice / a / the / run / normal / run / almost /can /distance / mouse . (Start typing from "the mice could...")


5. Normal mice can run about 900 meters before exhaustion, while the PPAR-delta-enhanced mice could run 1800 meters, or more than a mile, before running out of steam, said Evans. In addition, the marathon mouse runs an hour longer than the 90 minutes that a normal mouse runs, he said. It was especially surprising that altering a single gene produced such wide-ranging physiological changes in the mice. According to Evans, most physiologists believe ....... enhancing / by / complicated / that / a /performance / training / is / process. (Start typing from "According to Evans...")

6. Athletic training not only changes muscle fiber content, but also improves circulation and the motor neuron innervation into those muscles. Training also reengineers the heart ....... it / to /of / greater / to / a / volume / blood /allow /pump. (Start typing from " Training also reengineers the heart...")
