If venous PO2 decreases as exercise intensity increases, what do you know about the PO2 of muscle cells as exercise intensity increases?
To determine: The

- Unlike skeletal muscle, cardiac muscle doesn’t undergo tetany. Explain how this is achieved and why is this necessary?arrow_forwardExplain how the target heart rate (THR) helps adjust exercise intensity in times of high heat, humidity, or while at altitude.arrow_forwardIn addition to cardio-respiratory endurance_____ endurance can be built up by participating in aerobic exercise.arrow_forward
- If someone is on a heart-rate limiting medication, what is the best way to track exertion to ensure safety? Karvonen method Just ask questions Measure lactate threshold Rating of perceived exertionarrow_forwardThe effect of exercise upon the redistribution of blood pulse rate and ventilation changesarrow_forwardCompare heart rate and blood pressure responses to arm and leg work at the same oxygen uptake. What factors might explain the observed differences?arrow_forward
- Outline the circulatory responses to various types of exercise.arrow_forwardWhy is a high resting BP considered a risk for exercise testing? Based on your knowledge of BP responses to exercise, what effect would high resting BP have on the myocardium when a person reaches heavy and maximal levels of exercise? (Refer to RPP in your response)arrow_forwardDiscuss several possible reasons why blood lactate begins to rise rapidly during incremental exercise.arrow_forward
- If cardiac output is 16L/min during jogging, and 25% of total blood flow is being diverted to skeletal muscle, how much blood is being delivered to skeletal muscle in L/min? a. 2 b. 5 c. 6 d. 1 e. 4 f. 3arrow_forwardDuring heavy exercise, how much cardiac output may increase?arrow_forwardCan cardiac muscle exhibit (normally or under experimental conditions) summation or complete tetanus as does skeletal muscle? Why not? (highlight the main answer)arrow_forward
