Remember to check with your physician before beginning any
exercise program. He/She can help determine an appropriate
target heart rate. Medications often affect heart rate.
Robert Robergs, editor of the prestigious Journal of Exercise
Physiology, conducted a study in 2002 of the maximal heart rate
equation 220 - age. He found this equation “has no scientific
merit for use in exercise physiology and related fields.”
In his survey of research in this area, Robergs found several
other simple equations that were significantly more accurate.
The best equation he found was derived in 1994 by Oten Inbar:
205.8 - (0.685 * age)
The ES9.0 console uses the Inbar equation. Even though this is
the best available equation, it still has a possible range of error
of +/- 6 beats per minute.
Other similar equations that are also more accurate than 220 -
age are:
206.3 - (0.711 * age) (Londeree, 1982)
206.0 - (0.700 * age) (Tanaka, 2001)
208.8 - (0.734 * age) (Robergs meta study, 2002)
