week 5 case study

This week students will:

  1. Explain the four principles of exercise training.
  2. Analyze adaptations that occur in the cardiovascular and respiratory systems to aerobic training.
  3. Analyze the adaptations that occur within the human body to resistance training.
  4. Explain how regular exercise protects against disease and extends mortality.
  5. Evaluate age-related changes that occur in the cardiovascular system, respiratory system, and neuromuscular system.

Welcome to our final week together! Last week we compared the physiological responses of the cardiovascular, respiratory, and neuromuscular systems at rest and during exercise. We also explained acute and chronic physiological responses to exercise. This week we are going to explain the four principles of exercise training, adaptations that occur in response to aerobic training and strength training as well as how exercise can protect the body against chronic disease. Finally, we will look into some of the effects aging has on the cardiovascular, respiratory, and neuromuscular systems.


Imagine you accepted a new job as an exercise specialist at your local hospital working in the cardiopulmonary rehab department. You have had minimal experience working with clients over the age of 55. You are aware there are differences in exercise capacity in younger adults compared to older individuals. Therefore, you decided to observe this age group exercising before starting your new job. Find a facility in your area- YMCA, nursing home, fitness facility, local exercise groups, or hospital. Contact the manager or other personnel and set up a time to observe one of the exercise classes. You must observe a group exercise class. If it is not possible for you to observe a live class, please find an exercise class on the Internet of older adults participating in an exercise class. Some places to look include YouTubeFit, MSN, Wello, GymCube, iBodyFit.com, and Workouts On Demand.

Part One:

  • Explain your observations- where did you go or what class did you observe, approximate age of participants, characteristics of the participants such as gender, functional capacity of the adults in the class, etc.

Part Two:

  • Evaluate changes that occur in the body as a person ages and the impact this has on exercise capacity in the following areas:
    • Muscle mass
    • Joint flexibility
    • Nervous system
    • Pulmonary System Function
    • Cardiovascular System Function
  • Explain how regular exercise can decrease morbidity and mortality
  • Explain the purpose of pre-participation screenings and the Graded Exercise Stress Test
  • Evaluate two precautions you would take working with older clients compared to working with younger clients.

Your journal should be a minimum of three pages. It is acceptable to use informal tone in Part One of your journal; however, you should use a formal tone in Part Two of your journal. Your journal should be formatted in APA style. Use the text and one additional scholarly source to support your research and findings. All sources must be referenced and cited according to APA guidelines as outlined in the Ashford Writing Center. Submit your journal to your instructor as a word document by Day 5.

Carefully review the Grading Rubric (Links to an external site.) for the criteria that will be used to evaluate your journal entries.
