|Resting and Exercise State of the Respiratory, Cardiovascular, and Neuromuscular Systems [CLOs: 1, 2, 5]|
Prior to starting this discussion, review the required resources. Since you are the fitness expert, imagine your friend Megan, a 27-year-old adult female, has come to you for advice and information. She has never exercised regularly before, but as she gets older, she wants to take charge of her health and begin a regular exercise program. She has decided to start jogging three days a week and wants to prepare to participate in her first 5K race in three months. She is interested in knowing how her respiratory, cardiovascular, and neuromuscular systems will react at rest and during exercise. Choose one of these systems to explain to your friend Megan, and compare its functioning at the resting and exercise state. In your response, address the following:
- Identify the system you chose
- Explain the major organs that make up this system
- Compare how this system functions at rest to how it functions during exercise. Parameters to consider:
- Respiratory System:
- Tidal Volume
- Minute ventilation
- Depth and rate of ventilations
- Gas exchange in the tissues
- Ventilation limits
- Cardiovascular System:
- Heart rate
- Stroke volume
- Cardiac output
- Blood pressure
- VO2 Max
- Neuromuscular System:
- Chemical and mechanical action of the muscles
- Oxygen uptake
- Removal of waste products
- Motor unit recruitment
- Force of contraction
- Respiratory System:
- Explain two chronic adaptations in the system you chose that occurs with exercise.
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. Your initial post should be at least 250 words in length and be submitted by Day 3 to the discussion forum.
