Week 4 – DiscussionResting and Exercise State of the Respiratory, Cardiovascular, and Neuromuscular SystemsSince 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 choseExplain the major organs that make up this systemCompare how this system functions at rest to how it functions during exercise. Parameters to consider:Respiratory System:Tidal VolumeMinute ventilationDepth and rate of ventilationsGas exchange in the tissuesVentilation limitsCardiovascular System:Heart rateStroke volumeCardiac outputBlood pressureVO2 MaxNeuromuscular System:Chemical and mechanical action of the musclesOxygen uptakeRemoval of waste productsMotor unit recruitmentForce of contractionExplain 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.Guided Response: Due by Day 7. Read several of your classmates’ posts and respond to two students who have chosen a different system.  In your response, address a limitation or dysfunction of this system that may hinder exercise performance.  Each peer response should be at least 100 words in length and include one additional scholarly resource.
