What is the rate of oxygen consumption for a 198 lb cyclist exercising on a Monark leg ergometer at 2.2 kg and 80 revolutions per minute? Express your answer in relative and absolute units and METs. There is no further information.

One metabolic equivalent (MET) is the amount of energy required per unit of body weight to perform an activity at rest. In this lab, you measured your resting metabolic rate (RMR) while lying supine. One explanation for your VO2 test may be less than 3.5 ml/kg/min is that you need to convert VO2 measured in L/min to ml/kg/min. You need to multiply by 1000 because there are 1000 ml in 1 L, and then divide by your body mass (kg). VO2 (L/min) VO2 (ml/kg/min) 0.6 2.6 Metabolic equivalents (METs) are used by exercise physiologists to classify exercise intensity. METs can be used to estimate the energy expenditure of various activities. For example, someone consuming 3.5 ml/kg/min would have a resting metabolic rate twice that of the average person, so they would be at 2 METs. Likewise, someone consuming 10.5 ml/kg/min would have a resting metabolic rate three times that of the average person, so they would be at 3 METs. As you can see from the table above, METs increase with both treadmill speed and grade when running. The Centers for Disease Control and Prevention (CDC) suggests that adults get 150 minutes of moderate-intensity (<3-6 METs) physical activity per week to prevent diseases related to physical inactivity. Ask yourself, are you meeting the CDC's recommendation? Light - METs: Slow walking Moderate - METs: Brisk walking (4 mph), hiking, or jogging Vigorous - METs: Sitting, using a computer, vacuuming, mopping, carrying heavy loads Standing - METs: Light work Mowing lawn (walking power mower) - METs: 2.5 Fishing (sitting) - METs: 2.5 Bicycling (10-12 mph) - METs: 6 Bicycling fast (14-16 mph) - METs: 10-12 Playing most instruments - METs: 2.5 Recreational basketball game - METs: 6 Tennis singles - METs: 6 Tennis doubles - METs: 8 Soccer game - METs: 8 Adapted from: https://www.hsph.harvard.edu/nutritionsource/mets-activity-table/
