I'm aware that those engaged in Sports and Leisure are always looking for "hooks" that will get learners interested in what is being addressed.

has produced an interesting infographic (Information Graphic) showing the energy expended by athletes performing various athletic tasks. This one doesn't just mention calories; it mentions calories as well as...
  • watts; and
  • speed measurements.

Ideal for printing and displayed in...

  • health/well being;
  • physical education;
  • sports & leisure; and/or
  • science or mathematics learning environments; well as I was a mathematics/science(Physics) teacher I used similar images to hook my learners into a lesson.
