Based on the graph, identify and define B and provide 2 reasons why oxygen consumption levels remain high following the exercise bout.

The following graph depicts an athletes oxygen consumption for a submaximal exercise bout lasting approximately 5min in duration.a)Based on the graph, identify and define A.

What causes an oxygen debt in the body? a. anaerobic exercise b. aerobic exercise  c. acute exercise  d. chronic exercise

Select all that applyThe graph shows the percentage of energy derived from four major fuel sources during submaximal exercise over time. As the length of the exercise period increases, the use of which two energy sources increases?Multiple select question.Plasma fatty acidsBlood glucoseMuscle glycogenMuscle triglycerides

The primary determinant of oxygen uptake during exercise is the:Group of answer choicesExercise power outputExercise durationRelative mix of CHO and fat

Exercise is associated with alterations to many basic physiological processes, including changes in metabolism and the cardiovascular system.  As the intensity of exercise rises, both the cardiac output and oxygen consumption increase, as shown in Figure 1.Figure 1  Changes in cardiac output and oxygen consumption in response to various levels of exerciseThe cardiac output CO represents the volume of blood pumped by the heart in 1 minute.  The CO is calculated from the heart rate HR and stroke volume SV using the equationCO = HR ∙ SVEquation 1Experimental data has shown that the HR increases linearly with the exercise output Eout, leading to the relationshipHR = 0.65 ∙ Eout + 75Equation 2The metabolism of nutrients consumes oxygen and generates carbon dioxide as a waste product.  The amount of carbon dioxide generated depends on the type of macronutrient that is consumed.  For example, when carbohydrates are metabolized, every liter of oxygen consumed causes the generation of 1.0 liter of carbon dioxide.  Alternatively, the metabolism of fats leads to 0.7 liters of carbon dioxide per liter of oxygen, and the metabolism of proteins generates 0.8 liters of carbon dioxide for each liter of oxygen. Question 56While exercising on a treadmill, a person has a cardiac output of 15 L/min and produces carbon dioxide at 0.091 mol/min.  What is their ratio of metabolizing carbohydrates to fats during the exercise?  (Assume all gasses are ideal and are at STP.)A.1:2B.1:1C.1:0D.2:1Submit
