It is important for you to take the Fit Test under similar circumstances each time. Your heart rate is dependent on many
factors, including:
lamount of sleep the previous night (at least seven hours is recommended)
ltime of day
ltime since last meal (two to four hours after the last meal is recommended)
ltime since last beverage containing caffeine or alcohol, or cigarette (at least four hours is recommended)
ltime since last exercise (at least six hours is recommended)
For the most accurate Fit Test results, perform the Fit Test on three consecutive days and average the three scores.
NOTE: To receive a proper Fit Test score, the work done must be within a training heart rate zone that is 60 percent to
85 percent of the theoretical maximum heart rate. This rate is defined by the American College of Sports Medicine's
"Guidelines for Exercise Testing and Prescription" as equal to 220 minus an individual's age.
