* Exercise intensity can be gauged by METS: light <3 METs, moderate 3–6 METs, and
vigorous >6 METs, by % maximum heart rate achieved (light 40%–50%, moderate
50%–70%, vigorous >70%), or by level of perceived exertion on the Borg scale (light 7–12,
moderate 13–14, vigorous ≥15).

involve systematic training for the primary purpose of competition against others, at
multiple levels, including high school, collegiate, master's level, semiprofessional, or
professional sporting activities.
