- Trained athletes can perform so hard and so long because their intense training causes their muscles to adapt so they more readily and efficiently absorb lactic acid. 32. Who is the professor at the University of California, studying lactic acid in human muscles? - George A. Brooks is the professor at the University of California, studying lactic acid in human muscles. 33. Describe the experiment, in the early 20 th century, by Nobel laureate,Otto Meyerhof, that seemed to support the idea that lactic acid causes muscle fatigue. - He cut a frog in half and put its bottom half in a jar and then gave the frog’s electric shocks to make the muscles contract but after a few twitches the muscles stopped moving. 34. What did Dr. Brooks give his experimental rats? What happened? What is his conclusion? - In his experiment, Dr. Brooks gave his experimental rats radioactive lactic acids. During this, he found that they burned it faster than anything he had ever given them before. Finally, he concluded it was there for a reason and that it was a source of energy. 35. Through trial and error, coaches learned that athletic performance improved when athletes worked on endurance. Working on endurance increases the mass of what muscle cell organelle? What will this organelle then do with lactic acid? - Working on endurance increases the mass of their muscle mitochondria, which lets them burn more lactic acid. 36. What effect does this have on muscles? - This allows the muscles to work harder and longer.
