The below graph shows both ventilation and blood lactate concentration as a function of total oxygen consumption during a bout of exercise. Explain the relationship between these two variables and why these two measures (ventilatory threshold and lactate threshold) tend to occur around the same level of exercise intensity.

Graph the change in oxygen uptake during recovery from exercise. Label the excess post-exercise oxygen consumption (EPOC) (i.e., oxygen debt).
The below graph shows both ventilation and blood lactate concentration as a function of total oxygen consumption during a bout of exercise.

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).
The oxygen consumed after strenuous exercise stops is significantly greater than the oxygen deficit and is termed excess postexercise oxygen consumption (EPOC). Why is so much more oxygen required after intense exercise?
Describe how the diaphragm is used in activities of daily life. Include use in both concentric and eccentric actions. Focus on the execution phase unless the diaphragm's primary action is during the preparation phase.
Please explain the difference between the oxygen dissociation curve created by myoglobin (asymptotic) versus the oxygen dissociation curve created by hemoglobin (sigmoidal). Why does this occur? Myoglobin O₂ saturation (%) 100 80 60 40 20 0 20 Hemoglobin 40 60 80 100 120 Po₂ (mmHg)
Start by defining RER and explain how and why the resting value is established (think back to bioenergetics). Next, explain how and WHY (again, this requires an understanding of bioenergetics) RER changes as exercise intensity is increased (think VT and RCP). Hints: consider the points where the production of a gas increases drastically and why this occurs. Furthermore, consider that VT is often used to approximate AT. Also keep in mind the endogenous buffering systems.
Please write down at least 5 specific considerations for exercise with clients who have Pulmonary disease. (What do we need to consider with their prescription for exercise outside of the normal recommendations?)
Responses of the Pulmonary System to Acute Exercise during Short-Term, Light to Moderate Submaximal Aerobic Exercise, Long-term, Moderate to Heavy Submaximal Aerobic Exercise, Incremental Aerobic Exercise to Maximal *use graphs if necessary* asap please
Describe how walking exercises can be beneficial to a 70-year-old former smoker (quit in the last 3 months) who was diagnosed with chronic obstructive pulmonary disease. Describe how the movement would be beneficial to the client and using your best judgment discuss appropriate 1: duration and 2: intensity. (Use appropriate metrics with the ranges: HR, HRR, METS, RPE)
Explain how the target heart rate (THR) helps adjust exercise intensity in times of high heat, humidity, or while at altitude.
Altitude effects on exercise are caused mainly by increased CO2 production due to the physiological response to low pressure the increased influence of nitrogen gas at higher altitudes lowered 02 partial pressure the direct effect of low pressure on breathing
