Knowing your Maximum Heart Rate allows you to set more accurate custom heart rate training zones for the highest level of effectiveness and enjoyment. It can also show improvement over time and training, giving you critical feedback on your fitness level.
Your Max HR can be affected as much as 10bpm at times by factors including age, physical size of the heart, heat, personal hydration, and more. It can also change as fitness levels change. Many experts recommend doing a Cardio Fitness Assessment once every 4 to 6 weeks for the best results.
Determining Maximum Heart Rate for Heart Rate Training Zones
|
Equation 1 220 - Age |
175 Related training zones | The original formula, later found to have a fairly large standard deviation. |
|
Equation 2 210-[.5 x Age] |
187 Related training zones | One of the first modifications to the original formula |
|
Equation 3 Male Adjusted 202-[.55 x Age] |
177 Related training zones | Male (Gender Adjusted) |
|
Equation 4 Female Adjusted 216-[1.09 x Age] |
166 Related training zones | Female (Gender Adjusted) |
|
Equation 5 205.8−[0.685 × Age] |
174 Related training zones | The formula deemed least objectionable. This was found to have a standard deviation that, although large (6.4 bpm), was still considered to be acceptable for the use of prescribing exercise training HR ranges. |
|
Equation 6 191.5 − [0.007 × Age2] |
177 Related training zones | Nonlinear equation — HRmax = 191.5 − (0.007 × Age2). this has the tightest range of ±2–5 bpm |
|
Equation 7 Women - 206 − [0.88 × Age] |
166 Related training zones | The 2010 research conducted at Northwestern University revised the maximum heart rate formula for women. According to Martha Gulati, et al., it is: HRmax = 206 − (0.88 × Age)[9][10] |
Heart rate training experts will often say there is no such thing as a Maximum Heart Rate- instead, it is the point where your body starts to operated at its’ Lactate Threshold Heart Rate (LTHR) that you should be paying attention to. For ease of comparison, we equate your Lactate Threshold to be the 85% Max HR level, or the middle of Zone 4, for most people in good shape. The less in shape you are, the more potential your LTHR is less than 85%. From a perception standpoint, your LTHR is the point where you can't speak very easily anymore while you are working out.
For a great workout to determine your Lactate Threshold see the uber-heart rate training expert Joel Friel blog on the subject (requires running 30 minutes at race pace). While the assessment is intensive, it should provide, especially over multiple times, an excellent basis for determining your heart rate training zones.
