Question

Penny is a 27-year-old competitive runner. She currently runs 50-60 miles per week. Most of her running is on flat ground and she competes in distance races at a pace of 6:30 per mile. For an upcoming race she would like to know what pace she should try to maintain on the long hill with an average grade of 8%. She has a measured VO2max of 65 mL/kg/min. Assuming she can run between 75 and 85% of her VO2max for extended periods of time, determine the approximate speeds and pace per mile should she anticipate for this hill at a) 75% and b) 85%. Report m/min, mph, and min/mile for each answer
a) _______m/min, _______mph, ______min/mile
b) _______m/min, _______mph, ______min/mile

Answer 1

Answer:

a) 8.67m/min, 6.9225 mph, 0.1155min/mile

b) 7.647m/min, 7.8455mph, 0.1309min/mile

Step-by-step explanation:

pennys pace = 6:30 min/mile

= 13/2 min per mile

1 mile/(13/2)

= 0.15385 mile/minute

approximately 0.154

1 mile/(13/2minutes) = 1mile(6.5x1/60)

= 9.231 mph

from above

a. 75% VOx max

= 13/2 * 100/75

= 8.67min/mile

mph = 9.23 * 0.75

= 6.9225mph

mile/min = 0.154 * 0.75

= 0.1155m/min

b. 85% VOx max

min/mile = 13/2 * 100/85

= 7.647min/mile

mph = 9.23 * 0.85 = 7.8455mph

mile/min = 0.154 * 0.85 = 0.1309m/min
