Note: The online classroom is designed to time students out after 90 minutes of inactivity. Because of this, we strongly suggest that you compose your work in a word processing program and copy and paste it into the discussion post when you are ready to submit it.


Learning Outcomes

This week students will:

  1. Analyze how aerobic and anaerobic energy metabolism affects optimal energy transfer.
  2. Explain the advantages of having diverse sources of energy.
  3. Analyze the body’s energy systems and their contributions to exercise intensity and duration.
  4. Evaluate the effectiveness of the energy spectrum of exercise in the formulation of optimal training regimens.

Introduction

Our ability to move depends on how well our bodies are able to use food to release the energy required by our muscles. This week we will examine the body’s diverse energy systems and how they work together to extract energy from food in order to transfer that energy during rest and the stress of exercise. We will also evaluate the effectiveness of anaerobic and aerobic processes in the performance of exercise activities. Additionally, we will analyze how specific energy systems in the body contribute to the duration and intensity of sport-specific exercise activities.

Please click on the PowerPoint symbol to download this week's lecture, or click hereto open a PDF version of the lecture.

Remember, all work is checked for plagiarism. I will remind the class of this, because it happens and when it does, it puts your integrity and grade at risk.

Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses. Refer to the Discussion Forum Grading Rubric under the Settings icon above for guidance on how your discussion will be evaluated.

Aerobic Versus Anaerobic: What is the Difference? [CLOs: 2, 3, 5] [WLOs: 1, 3]


After reading Chapter 5 and 6 in the course text and viewing Physical Training Strategies: Preparing for a Purpose: Energy System in the Body, select one of the following: a triathlete, a football player, a gymnast, and one phase of their sport. For example, if you choose the triathlete you can choose the cycling phase of their activity, or if you choose the football player, you could choose the sprint phase of their activity, or if you choose the gymnast, you may choose the backflip phase of their activity.

  • As your athlete performs the chosen activity, discuss whether rapid or slow glycolysis is the most effective means of energy transfer?
  • What physiological factors contributed to your analysis (e.g. hydrogen release, lactate formation, glucose catabolism, etc.)?
  • Explain the benefits of lactate for optimal performance of the chosen activity.

Your research and claims must be supported by your course text and a minimum of two additional scholarly sources. Use proper APA formatting for in-text citations and references as outlined in the Ashford Writing Center.

Guided Response: Review some of your classmates’ posts. Identify at least two classmates who chose a different athlete than you chose and analyze the appropriateness of the type of glycolysis they discussed. Then, explain if you agree with the benefits of lactate identified for their chosen activity. Support your reasoning for each response to your classmates with at least one scholarly source.

week 2 discussion 2

This discussion will has three parts:

Part One: Your initial post as The Training Consultant (Due Day 3)
Before completing this discussion, watch Cell Metabolism and Respiration. Then, imagine that you are a training consultant for a professional soccer player. The soccer player wants to know how the body creates ATP from fat, protein and carbohydrates. In your post explain:

  • Fat metabolism
  • Protein metabolism
  • Carbohydrate metabolism
  • The benefits of having different energy sources


Your research and claims must be supported by your course text and a minimum of two additional scholarly sources. Use proper APA formatting for in-text citations and references as outlined in the Ashford Writing Center.

Guided Response:

Part Two: Your reply as The Soccer Player (Due Day 5)
Review some of your classmates’ posts. Imagine that you are the soccer player receiving this information from the consultant (your classmate). What questions do you have for the consultant? Do you agree with the information provided? Why or why not?

Respond to at least one of your classmates. Support your reasoning with at least one scholarly source.

Part Three: Your rebuttal as the Training Consultant (Due Day 7)
Rebut at least one of your classmates’ responses to your initial post. Support your reasoning with at least one scholarly source.
