Heart Rate Zone

Heart rate is described by the number of times your heart beats in a minute. At rest, the average adult will

have a heart rate of about 72 beats per minute (BPM). As one begins to exercise, heart rate increases

and continues to increase as exercise intensity or difﬁ culty increases.

Monitoring your heart rate is an effective way to control

the intensity of your workout and subsequently the

results it will have. Whether you are a new participant

or one with a great deal of experience, weight loss and

other performance goals can be achieved by controlling

the intensity of your workout.

The American College of Sports Medicine recommends

that healthy adults exercise between 55 and 85%

of their heart rate max. Your heart rate max can be

estimated by subtracting your age from 220. Multiply

that estimated heart rate max by .55 to estimate

the lower end of your heart rate training zone. Then

multiply your estimated heart rate max by .85 to

estimate the higher end of your training zone. This

heart rate training zone gives you a range of intensities

at which to exercise. See Figure 4.

Meaning of % Grade

A 1% grade is not the same as a 1 degree incline.

The % grade is the relationship of the measurement

of rise over the measurement of run (also called slope).

For example, a 1 foot (meter) rise in height over a length

of 100 feet (meters) is a 1% grade. Expressed as a

mathematical formula, the grade is calculated as follows:

1 ft. (m) / 100 ft. (m) = 0.01 = 1%

With respect to treadmills, the percent grade is roughly equal to the increase in height (rise) of the

treadmill divided by the length (run) of the treadmill.

The degree of incline can be related to % grade by taking the Arctangent of the grade. For instance, 15%

grade is equal to 8.53 Degrees (ArcTan(.15)=8.53º). The opposite is true to determine % Grade from

Degree of incline (Tan (8.53º)=.15).
