What strategy would best measure the influence of temperature and PTU on oxygen consumption?

What is the RER of an individual with an oxygen consumption of 220 ml/min and a carbon dioxide production of 182.6 ml/min? Report your answer to 2 decimal points. QUESTION 29 What percent of the individual's oxygen consumption in the previous question is being used to combust carbohydrate for energy? Round your answer to the nearest whole number and answer with a number only as units are given in the question.

After jogging for a while, a person begins to experience burning muscle fatigue. Explain the reason for this. Be sure to identify the type of respiration responsible.

Mark's maximal oxygen consumption on an exercise test is 55 ml/kg/min. What MET level did he acheive on his exercise test? Hint: When going from METS to ml/kg/min your multiply by 3.5 ml/kg/min. When going in the opposite direction, ml/kg/min to METS you divide by 3.5 ml/kg/min.

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.
