As noted in Chapter 9, the VO2max of people tends to decline after age 30 by about 9% per decade for sedentary individuals, but it declines less than 5% per decade for people who stay active. The average VO2max in healthy 30-year-olds is about 3.1 L/min. Using the information given here, what would the average VO2max be in 60-year-olds who have been sedentary throughout their lives and in 60-year-olds who have stayed active? Keep in mind that the decline is exponential. Consider the activities in Table 9.1, and recall from Chapter 7 that 1 kJ is equivalent to about 0.05 L of O2 in aerobic catabolism. How would you expect sedentary and active people to differ in their capacities for each of those activities in old age? Explain.

Question

As noted in Chapter 9, the VO2max of people tends to decline after age 30 by about 9% per decade for sedentary individuals, but it declines less than 5% per decade for people who stay active. The average VO2max in healthy 30-year-olds is about 3.1 L/min. Using the information given here, what would the average VO2max be in 60-year-olds who have been sedentary throughout their lives and in 60-year-olds who have stayed active? Keep in mind that the decline is exponential. Consider the activities in Table 9.1, and recall from Chapter 7 that 1 kJ is equivalent to about 0.05 L of O2 in aerobic catabolism. How would you expect sedentary and active people to differ in their capacities for each of those activities in old age? Explain.
