Grading descriptions
(1) Energy expenditure Document numbers of METs shown on an exergame.
#
Numbers of METs
(2) Cardiorespiratory fitness: percentage of heart rate reserve (HRR) Use the user’s age, his/her resting heart rate, and peak heart rate during an exergame to calculate the HRR.
0–100
Use the following formula to calculate the percentage of HRR: (peak heart rate − resting heart rate) ÷ (220 – age – resting heart rate) 100%
(3) Cardiorespiratory fitness: perceived exertion Use the Adult OMNI Scale of Perceived Exertion for the Walking/Running Exercise to ask about feelings of exertion during an exergame.
0–10
The user reports a perceived peak maximal exertion score that is consonant with the score depicted visually by the figure walking/running at the bottom (rating 0) and top (rating 10) of the hill, as presented in the Adult OMNI Scale of Perceived Exertion for the Walking/Running Exercise
