Question
How many kilocalories would Elliot (60 kg) use if she walked on a level treadmill at 3.5 mph for 45 minutes?

Transcribed Image Text:WALKING EXAMPLES
Common Walking Speeds: anything less than 4.0mph
4.0 - 5.5mph is a gray zone….. some people walk and others run
at these speeds. IF the speed falls in this range, walking or
running/jogging will be specified in the wording of the problem.
2.0 mph, 0% grade:
VO2 = 3.5 ml/kg/min + (0.1ml/kg/m * 2.0mph *26.8
m/min/mph) + (1.8 * 2.0 * 26.8 * 0)
= 3.5+ 5.4 +0
8.9 ml/kg/min
3.0 mph, 5% grade:
VO2 = 3.5ml/kg/min + (0.1ml/kg/m*3.0mph*26.8 m/min/mph)
+ (1.8*3.0*26.8*0.05)
= 3.5+ 8.0 +7.2
= 18.7 ml/kg/min
