NATIONAL CENTER FOR CASE STUDY TEACHING IN SCIENCE I Hate Running! And Lactate Is to Blame, Right? by Ashley E. Rhodes, Timothy G. Rozell, and Abigail R. Wilson* Kansas State University, Manhattan, KS Introduction I hate running! That was Shelby’s first thought upon hearing the announcement in class about an exercise challenge where students in two different courses competed to see which course could log the most miles during a semester. Her second thought was that she was sorry she even came to class this day; her friends were excited about starting the exercise challenge right away and wouldn’t stop talking about it but Shelby was skeptical and not at all enthused. For as long as she could remember running was difficult; she always felt out of breath and her muscles burned painfully whenever she would attempt to run more than a mile. The next day would be even worse due to muscle soreness. Because of this, Shelby never stuck to any sort of training program even though she had heard about the benefits of doing so in several kinesiology courses she had taken in college. For her, it was always much easier to tell someone else what they needed to do to get in shape than having to follow her own advice. “So, what do you think about this exercise challenge?” Patrick asked after class. Shelby just rolled her eyes and said, “I think you’ll excel like you do with everything, but I’m not interested.” Patrick just giggled. “But what if we exercised together? We could use the time to not only get in shape but also discuss the concepts we’re learning in class. Maybe it would even help our grades a little.” Shelby definitely needed help with the course material and Patrick talked a lot about how he had in-depth experience in many areas of anatomy and physiology. “Ok,” Shelby said, “but don’t expect me to be able to keep up with you. I can tell from looking at you that you exercise a lot.” Patrick just smiled and said, “How about we start first thing tomorrow morning with just a two-mile run? Maybe we could even do a few sprints for fun!” As Shelby had predicted, the run was physically hard. Her muscles burned, she was short of breath, and she couldn’t wait for it to end. “Wow, that was awful,” Shelby said to Patrick as they sat in the grass, stretching after their run. “I never want to do that again! I’m just not made for running, especially endurance running. I’m sore already thanks to all the lactic acid in my muscles.” Patrick shot her an inquisitive look and said, “I don’t think it’s the lactic acid that’s making you sore, but I could be wrong. I remember hearing something about this in class.” Shelby paused for a moment and then said, “Maybe it’s lactate then? Isn’t that produced in skeletal muscle during exercise? Or maybe lactic acid and lactate are the same thing? My track coach in high school used those terms a lot so I think they might be interchangeable. He even made us do drills that he called ‘lactates’ just to make us sore, so it’s got to be one of them.” “Well, regardless,” Patrick said, “I know lactic acid and lactate are only produced in muscle when it’s being heavily used and runs out of oxygen. Maybe with training you won’t make those compounds at all and won’t be sore after you run.” Activity 1 The conversation above highlights several common misconceptions about skeletal muscle cells, the effects of training, and causes of muscle soreness. Can you identify these? Jot down your thoughts below before continuing.
