You have a 47-year-old

male client who has an extensive history of surfing. You have conducted a

VO2max test on a bike to assess your client’s VO2max. The highest value the

metabolic cart reads from the test is 56ml/kg/min. From the results, you find

it is difficult to find a plateau in the VO2 reading at the end of the test.

However, the client has reported a RPE of 10 (out of 10), RER of 1.2 and a

blood lactate of 18.3 mmol/L. Based on the information provided, what is the

56ml/kg/min likely to represent?
