- List two supplements that may be of benefit to Steven for a marathon. What are the potential mechanisms and benefits of using these two supplements? What protocol, including the timing and dose, would you suggest Steven use for each supplement and why?Write a statement on Stroke type by using SMART goal Specific... Measurable... Attainable... Realistic... Timely...Describe how cardiac performance is measured in cardiac output. In your answer, be sure to describe the role of stroke volume (SV) and HR by defining each and discussing factors that influence SV in particular both during acute exercise and following chronic exercise training.
- Choose to discuss either acute or chronic adaptations to the circulatory and respiratory systems. For ease of discussion, include your choice in the thread title. Include a brief introduction on the role of these systems (circulatory and respiratory) during exercise. Identify the following variables and how they change (either with acute exercise or long-term training). You can show this however you like, but a table or chart may be useful. Cardiovascular: Heart Rate, Stroke Volume, Cardiac Output, Blood Pressure Respiratory: Tidal Volume, Minute Ventilation, Breathing Frequency Explain why it makes sense that these variables change/adapt as they do. What would happen if they did not adapt? Be sure to include reputable resources to back up the information you share. For follow-up posts, be sure to engage with at minimum one post covering each topic (acute or chronic exercise).20 yr old male Maximal Exercise Stroke volume Untrained: Trained: Heart rate Untrained: Trained: Cardiac output Untrained: Trained:Pain in the leg muscles that occur during exercise and is relieved by rest is known as _______________. This condition is due to poor circulation and is associated with peripheral vascular disease.
- Calculate %HRR for an individual (63 years old) who has a heart rate of 140 during running. The resting heart rate of this individual is 60 (HRmax= 208-0.7* age).Define preload, afterload, and contractility, and discuss the role of each in the increase in the maximal stroke volume that occurs with endurance training.200 Curve 1 175 Curve 2 150 125 Curve 3 100 75 50 25 50 100 150 200 250 300 350 400 LV End Diastolic Volume (mL) Use the information in this paragraph and the image above to answer the question below. This figure shows the relationship between EDV and SV. Curve 2 is representatíve of a normal individual sitting on a bike, resting. There are two other curves illustrated and there are multiple points landmarked with a "o" and the letters "A to F". You can assume that the only changes in relevant variables are described in each question. If a variable is not mentioned you can assume that it has not changed. The starting point is "A". Select an appropriate pointif there was an increase in cardiac inotropy. 23 D. Stroke Volume (mL)
- Define stroke volume (SV)With endurance athletes, an increased stroke volume at rest will occur because of Select 3 correct answer(s) Increased blood volume Increased myocardial contractility Increased compliance of the left ventricle Increased vagal toneExplain how the target heart rate (THR) helps adjust exercise intensity in times of high heat, humidity, or while at altitude.
