Rating Notes: Tennis Equivalent

At the time of rating, FitXR has 3 workout types: Box, Dance, and High-Intensity Interval Training (HIIT). This rating is based on a Box workout on advanced difficulty. 

FitXR is a cardio workout that focuses on upper-body exercise and the occasional lower-body movements. Its primary exercise comes from boxing movements that players will use to punch incoming targets or dodge obstacles. A combination of straight jabs, hooks, uppercuts, and blocks are performed in sync with targets appearing to in-game music. Occasionally, obstacles will appear and require the player to duck and/or lean to the side to avoid them. FitXR does not generally require the player to move their feet in order to be successful at the game. Therefore, this game can be played in small spaces.

Quick Facts:

Status: Metabolic Rating: This game was tested by measuring oxygen
consumption with a metabolic cart in April 2022.
Peak Observed Sustained MET: 8.42 METs
Average Observed METs: 7.94 METs
Est. calories expenditure per min.: We observed a 30-minute average MET score of 7.94, with a 5-minute sustained peak average of 8.42 METs. This is an energy expenditure of 8.34 kcals to 8.84 kcals per minute during our tests. This estimate is based on the assumption that the subject weighs 60kg, a common research standard for average weight. Please see the table below for an estimate of calorie expenditure for your weight based on the observed METs.
Explanation: Experiences are rated based on their observed Metabolic Equivalent of Task score, or a MET score, during testing in the lab. A MET is a multiple of your base resting rate. 1 MET is equal to 1x resting metabolic rate. 2 METs is equal to 2x resting metabolic rate, etc. METs can be used to calculate an estimated calorie burn during that task based on that person’s weight, which is shown in the chart below.

This game’s 30-minute average rating of 7.94 METs means that we observed an average energy expenditure of 7.94x the rater’s base metabolic resting rate over 30 minutes of gameplay. Its 5-minute Peak Average refers to the maximum 5-minute average we observed during testing, anywhere in the game. Together, the two represent the overall average we observed during play, and the maximum peak that we observed, such as during a particularly intense level.

The first is likely more useful for comparing energy expenditure during typical play as a regular player. The second may be more useful for identifying games that, if played for exercise, may have sections that are substantially different levels of exercise than the rest of the game (such as specific game modes, etc).
