Instructions

You must upload a word document for this writing assignment. You cannot copy and paste your assignment, it must be submitted as an attachment.

In this week’s content we learned how our metabolic system produces energy during exercise. To continue studying this topic, please answer the following four questions about the lactate threshold and training. You are encouraged to use outside sources to locate this information and it’s important to answer these questions using your own words. Be sure to cite your source(s) of information, both in the text and at the end of the paper. A grading criteria indicating point values for each question is located below.

1. What is the lactate threshold? Define it using proper terminology and explain how it relates to aerobic and anaerobic metabolism.

2. What factors influence the percent of VO2max at which the lactate threshold occurs? That is, for some people, the lactate threshold occurs at 50% of their max while for others, it occurs at 75% of their max. What causes these differences? In addition to listing the factors, explain how they would increase or decrease the threshold.

3. What is lactate threshold training? Describe what it means and two methods used in this style of training.

4. Provide data from a research article that shows how lactate threshold training can impact aerobic performance.
