Nutritional Ergogenic Aids Case Study

OPTION 1: Nutritional Ergogenic Aids Case Study

Jason, a 16-year-old high school track athlete, as set a goal to improve his 100 and 200 m sprint times. He has seen the muscle development evident in elite sprinters and therefore desperately wants to increase his muscle mass, strength, and power. After talking about training regimens, daily nutrition, and supplementation with numerous other athletes at track meets, he has decided to begin taking several supplements to help him reach his goals. His mother is very conscientious about preparing a nourishing supper; however, Jason prepares his own breakfast and lunch, which he admits typically do not consist of quality food choices. Currently he is resistance training 2 to 3 times per week and taking the following supplements: “mega” multivitamin/mineral supplement, boron, ornithine and arginine, chromium picolinate, and whey protein.

What would you suggest to Jason to help him achieve his personal goal of increasing muscle mass to becoming stronger, more powerful athlete?

Explain the function of the cardiovascular and respiratory systems as well as how these systems work together to meet the demands of activity.

Explain the function of the cardiovascular and respiratory systems as well as how these systems work together to meet the demands of activity. Discuss the process of gas exchange as well as coronary artery disease and chronic obstructive disease and explain how these chronic diseases can lead to dysfunction of these systems.

To complete the following activity, you will need paper, a pen, and a clock or stopwatch with a second hand. To begin, take the Physical Activity Readiness Questionnaire (Links to an external site.)Links to an external site. (PAR-Q). The PAR-Q is a screening tool to determine if a person should check with his or her doctor prior to completing an exercise program. If it is determined that you should not exercise, please find an adult (18 years of age or older) family member or friend to complete the assessment for you who has been cleared to exercise through the PAR-Q assessment. You can record the results of your partner.

  • Measure resting heart rate (refer to page 13 of the      text on how to take a pulse).  Count your respirations in 1 minute.      Record results.
  • If you are able to safely do so, exercise for 3 minutes      (jog in place, do jumping jacks, jump rope, push-ups, sit ups, etc.)
  • Immediately take your pulse for 10 seconds. Record that      number.  Have your partner record your respirations for 1 minute.
  • Rest for 5 minutes. Take your pulse again for 10      seconds. Count your breaths again for 1 minute.

In your initial post:

  • Enter the results from the heart rate activity above.
  • Describe the function of the cardiovascular system and      the respiratory system and how they work together.
  • Describe how the cardiovascular system adjusts to meet      the demands of exercise. Use appropriate terminology such as stroke      volume, respirations, and pulse.
  • Describe why an untrained person’s heart rate and      breathing rate would take longer to return to a resting rate compared to a      person who is in good physical condition.
  • Explain the relationship between heart rate and      breathing rate during physical activity.
  • Discuss contributing factors to coronary artery disease      (CAD).  Explain how CAD leads to dysfunction of the cardiovascular      system.
  • Discuss contributing factors of chronic obstructive      pulmonary disease (COPD). Explain how COPD leads to dysfunction of the      respiratory system.

Use two scholarly sources (one may be your course text) to support your initial post. All sources must be referenced and cited according to APA guidelines as outlined in the Ashford Writing Center. Your initial post should be at least 250 words in length.

Guided Response: Respond to two peers; one reply should relate to CAD and the other response should pertain to COPD. Please cover the following in each response: Contrast your answers pertaining to the contributing factors for CAD/COPD with those discussed by your peer. How could environmental factors contribute to CAD/COPD? Each peer response should be at least 100 words in length and supported by one scholarly source.

Briefly describe the normal function of these three systems and associated organs.

Various chronic diseases and disorders can affect our immune, gastrointestinal, and urinary systems, as described in Chapters 14, 15 and 16 of your course text.  In your initial post:

  • Briefly describe the normal function of these three      systems and associated organs. 
  • Choose and briefly describe one chronic disease or      disorder for each of the three systems and explain how the      diseases/disorders alter the normal function.
  • Examine potential causes for the disease or disorder      and list signs and symptoms that indicate the disease has developed.
  • Analyze actions people can take to reduce their risk of      developing the chronic disease or disorder.  Briefly explain how      these actions would impact the environment.

Your initial post should be at least 250 words in length.  Use medical terminology, your course text, and at least one additional scholarly resource to support your points. All sources must be referenced and cited according to APA guidelines as outlined in the Ashford Writing Center .  

Guided Response:  A comorbidity is a co-existing or additional disease to the original disease examined.  According to the National Institute on Drug Abuse (Links to an external site.)Links to an external site., comorbidities are “interactions between the illnesses that affect the course and prognosis of both” (2010, para. 1).  Read several of your classmates’ posts and respond to at least two of your peers. Each response will address comorbidities associated with the disease chosen by your classmate. List signs and symptoms associated with the comorbidity.  List factors that contribute to the comorbidity’s development as well as steps the person can take to avoid the development of the problem. Each peer response should be at least 100 words in length and should be supported by one scholarly source.

Nutrition Food Facts Label.

please find a protein supplement with a Nutrition Food Facts Label.

Here is an example, CytoSport Muscle Milk Chocolate Protein Supplement Powder sold by Walgreens. You can find your protein supplement using the web or going to the store. Once you have found a product, locate the list of ingredients and nutrition label. You will need this for your forum discussion.

Do not use a supplement someone else has selected. Once you have found a supplement, go to this week’s forum and see if anyone has posted that supplement’s name. If the name is not present, then open a new thread and type the product name in the thread’s title box. This will reserve that supplement for you. You can add the required initial forum discussion information any time before the required due date. To add your discussion after posting your supplement title, select edit thread.

In the Forum, list the ingredients and tell the class the functional property of each ingredient. In other words, what it contributes to the product. Don’t confuse functional properties with nutritional/health properties. For example, one of the ingredients in CytoSport Muscle Milk Chocolate Protein Supplement Powder is fructooligosaccharides. This ingredient contributes sweetness to the product. I suggest you start with this website to find the functional property: http://nutritiondata.self.com/topics/food-additives. If the item is not in this list, then try the Natural Medicines Database. You can find this in our library under databases. I attached directions to access the Natural Medicines Database. If your ingredient is not in the database, then search for it on the web. I provided links to several other databases or websites below. Be very careful that you tell us the functional properties, not the health properties, of the ingredient.
