We all know that the zones in the PULSE system are based on the max heart rate of the individual, working from the grey zone at resting and the red zone at max or over. The formula used to calculate the max HR for an individual is the popular Londeree and Moeschberger (University of Missouri) method.
There are some 9Round owners who worry that the max heart rate calculations in PULSE are not accurate. However, the Londeree and Moeschberger method is accurate for the vast majority of people. The only way to get a more accurate reading of a person's customized and individualized heart rate, to 100% accuracy, would be for the member to go to a medical facility and get a VO2 test done by a practitioner. Since we aren't in the medical advice business, we feel confident with the readings PULSE gives us.
One myth prolonging the desire to change people's max heart rate in the PULSE system, is that as you get more fit, your max HR increases. This is simply not the case. While your efficiency will definitely increase, your max HR actually stays at the same recommended number because your age stays the same. You are able to workout harder without hitting your max as you get more fit, but this happens as you still follow the guidelines based on your max HR. You are just in better shape as you are doing it.
Simply said: Max HR is based on age, not on fitness level. There are many outside factors that may result in prolonged periods in the red zone. Because we are not qualified to diagnose these issues, we feel strongly that unless a doctor has advised otherwise, max heart rate should be based strictly on age.
So, what do we do if a member is spiking into the red with seemingly little effort? Answer: follow that heart rate!
Bottom line: The heart rate reading really just is what it is. Everyone is different and there are a myriad of reasons that someone may spike into the red easily, which would be dangerous to make assumptions about. Maybe they didn't sleep well or they have a cold coming on. Perhaps they have anxiety, or worse, there is a deeper medical concern. Who knows, and who are we to say? We are not doctors, nor are we qualified to simply pick a higher number, type it in and click save.
If someone is truly troubled by how little effort they are putting forth, while remaining in the red zone, they may want to consult with their physician. Otherwise, for 95% of our members, this issue is fixed by a dedicated focus to following the zones and aiming for the yellow as often as possible - even if it means slowing down their workout more than they'd like to! Putting the best interest and safety of our members first is our duty as Champion Trainers, and using the max HR guidelines, as set forth, will help us get them in the absolute best shape of their lives.
