(2 marks)

[Insert figure somewhere here]

Present a figure of your participant’s relationship between HR and VO2:
(2 marks)

[Insert figure somewhere here]

Using the figures above, provide an estimate of your participant’s absoluteand relative maximal VO2 and peak work rate.
(3 marks)

According to normative (population) values for VO2max, how would you describe your participant’s estimated VO2max(i.e., how fit are they?) (30 words max.)
(1 mark)

Please indicate what source of information you used for your normative (population) values for VO2maxand why this source was appropriate? (60 words max.)
(2 mark)

Question 2. Estimating your participant’s blood lactate threshold.
Present a figure of your participant’s relationship between lactate & power output:
(2 marks)

[Insert figure somewhere here]

Present a figure of your participant’s relationship between lactate & VO2:
(2 marks)

[Insert figure somewhere here]

Using the figures in Q2A and Q2B, are you able to identify your participant’s blood lactate threshold (BLT)? If you can, please annotate/draw on that figure showing how you visually determined the BLT. Report the absolute and relative exercise-intensity (i.e., power output and %VO2max) at the BLT in your response below.

(2 marks)
If you CAN determine the BLT, make sure that you annotate the figures in Q2A and Q2B such that your assessor can clearly see how you have visually determined the BLT. You must report the BLT as an absolute and relative exercise-intensity (i.e., work rate and %VO2max) in your answer here.
If you CANNOT determine the BLT, you must use this space to describe two (2) reasons why the BLT cannot be determined from your data. Your job here is to convince the assessor that there is a good reason for not finding the BLT in your participant’s data. Provide details but respect the maximum word limit for this section.

Using the figures in Q2A and Q2B, are you able to identify your participant’s onset of blood lactate accumulation (OBLA)? If you can, please annotate/draw on that figure showing how you visually determined the OBLA. Report the absolute and relative exercise-intensity (i.e., power output and %VO2max) at the OBLA in your response below.

If you cannot determine the OBLA, please detail your reasons why it cannot be determined using your data. (100 words max.)
(2 marks)
If you CAN determine the OBLA, make sure that you annotate the figures in Q2A and Q2B such that your assessor can clearly see how you have visually determined the OBLA. You must report the BLT as an absolute and relative exercise-intensity (i.e., work rate and %VO2max) in your answer here.
If you CANNOT determine the OBLA, you must use this space to describe two (2) reasons why the OBLA cannot be determined from your data. Your job here is to convince the assessor that there is a good reason for not finding the OBLA in your participant’s data. Provide details but respect the maximum word limit for this section. You may wish to cite similar reasons as provided in your answer to Q2C above; however, please write your response here in full sentences. DO NOT simply state “see above”.

Question 3. Estimating your participant’s “cross-over” point.
Present a figure of your participant’s relationship between fuel (relative % contribution to total energy expenditure) versus power output:
(2 marks)

[Insert figure somewhere here – remember to plot %CHO and %FAT in the same figure]

Using the figure in Q3A, are you able to identify your participant’s “cross-over” point in fuel utilization? If you can, please annotate/draw on that figure showing how you visually determined the “cross-over” point. Report the absolute exercise-intensity (i.e., power output) at the “cross-over” point in your response below.

If you cannot determine this point, please suggest one (1) reason why it cannot be determined using your data. (100 words max.)
(1 mark)
If you CAN determine the “cross-over” point, make sure that you annotate the figure in Q3A such that your assessor can clearly see how you have visually determined the “cross-over” point. You must report the “cross-over” point as an absolute work rate in your answer here.
If you CANNOT determine the “cross-over” point, you must use this space to describe two (2) reasons why “cross-over” point cannot be determined from your data. Your job here is to convince the assessor that there is a good reason for not finding a “cross-over” point in your participant’s data. Provide details but respect the maximum word limit for this section. Please note that stating “we did not see a cross-over point because the lines did not cross over” is not an adequate response.

Question 4. Estimating your participant’s blood pressure at VO2max.
Present a figure of your participant’s relationship between SBP, DBP and MAP & power output:
(2 marks)

[Insert figure somewhere here – remember to plot SBP, DBP and MAP in the same figure]

Using the figure in Q4A, provide an estimate of your participant’s SBP, DBP and MAP at an exercise-intensity corresponding to their estimated peak power output. Discuss your approach, and outline any assumptions you have made to arrive at your answer.
(120 words max.)
(3 marks)
To answer this question, you must describe the thought processes behind your approach, including any assumptions you have made, and any working out for equations you may have used to arrive at the answer. You must use your own group’s data to determine this answer. You cannot answer this question by directly quoting normative (population) values for blood pressure during maximal exercise.

Question 5. Estimating your participant’s maximal cardiac output, avO2 difference and total peripheral resistance.
Provide an estimate of your participant’s maximal stroke volume (SVmax) using normative (population) values for a demographic population similar to that of your participant. In your answer, please also indicate what source of information you used for your normative (population) values for SVmaxand why this source was appropriate? (75 words max.)
Show working out (if necessary) and report your answer in the correct units. We will accept references to our lectures/tutorials/practical notes, relevant textbooks, and journal articles. No websites, blogs, or other tertiary sources of evidence are permissible.
