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.

/in /by

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.
