Question text WORKSHOP QUESTION a) Following a typical aerobic exercise training program, we would not expect a professional athlete to display Answer 1 Question 20[select: , Increased lactate stores, Increased lung capacity, Increased heart size, Increased blood volume].b) During a dive, we would expect heart rate to Answer 2 Question 20[select: , decrease, remain constant, increase] and lactate production to Answer 3 Question 20[select: , remain constant, decrease, increase]. This is because Answer 4 Question 20[select: , blood flow to all organs is maintained, blood flow to the heart and lungs is maintained, blood flow to peripheral tissues is maintained, blood flow to essential organs is maintained].c) Fill in the blanks with one of the terms in the following list (do not include the commas). Please note, the terms must be spelled exactly as shown, no punctuation marks or plural words are permitted, uppercase letters must not be used, and you cannot use any word that is not listed. The same word may be used more than once or not at all.Aerobic respiration, anaerobic respiration, blood air threshold, blood oxygen threshold, decreasing, dive gas threshold, dive lactate threshold, heart rate, high, increasing, less than, low, metabolic rate, more than, oxidising, oxidative phosphorylation, oxygen, remaining constant, respiratory rate, waterThe following graph shows the amount of gaseous oxygen in arterial blood, venous blood and alveoli of Emperor penguins undergoing a breath-hold dive.During region 1, the penguin is/are Answer 5 Question 20[input] existing oxygen supplies within their circulatory system, while you would expect the blood lactate levels are Answer 6 Question 20[input] by an order of Answer 7 Question 20[input] 0.5 mmol/litre/min.
