Question

what makes the energy cost of swimming a given distance average about four times more than the energy cost of running the same distance?

Answer 1

Step-by-step explanation:

Swimming requires a lot more muscular effort than running because the swimmer is pushing against the water instead of the ground, which requires more energy. Additionally, the swimmer must overcome water resistance, meaning that their muscles must work harder to move their body through the water than they would if they were running. This increased amount of effort translates to a much higher energy cost for the same distance
