Final answer:
Matching activities with their MET values involves sorting them based on energy expenditure levels. Shoveling has a MET value of 6, while running is higher with a value of 10. Swimming corresponds to a MET value of 8, and casual cycling has a value of 4.
Step-by-step explanation:
The question asks about matching different activities with their corresponding Metabolic Equivalent of Task (MET) values. MET is a physiological measure expressing the energy cost of physical activities and is defined as the ratio of metabolic rate (and therefore the rate of energy consumption) during a specific physical activity to a reference metabolic rate, set by convention to 3.5 ml O2 kg-1 min-1 or approximately 1 kcal kg-1 hour-1. Here are the matches for the activities given:
- Shoveling - 6 (Moderately high energy activity, similar to cycling or playing tennis)
- Running - 10 (High energy activity, similar to running cross-country)
- Swimming - 8 (High energy activity but less so than running, similar to swimming breaststroke or cycling at 21 km/h)
- Cycling - 4 (Lower intensity activity, similar to cycling at 13-18 km/h)
