Your heart rate range based off a formula. You use a HR monitor to keep track. I train using a particular formula.
According to Jorge (amiine), a BTer and a coach, he utilizes a strategy/plan, below:
****************************************************
First you have define how are you basing your heart rate zones otherwise you are going to get different responses and confusion.
You can base your HR zones on Max HR which is the most widely used but not most accurate because: some athletes use the 220- age or 180- age formulas to determine it and the values can be very inaccurate for different individuals. If an athlete performs a Max test, those are very stressful on the body hence not everyone is capable of pushing to their true max. Plus Max HR is more a genetic function rather than a fitness/performance indicator.
You can base your HR zone on VO2 max but to obtain your real value you need to do lab test which can be expensive and still the results can be misleading as certain equipment is not very reliable (You can do field testing to get close guesstimates as well). The problem with VO2 is that same as max HR it is more a genetic function rather than a fitness/performance indicator because while having a high V02 indicates potential it doesn’t mean the athlete necessary will perform better those with lower values.
Last you can base your HR zones on lactate threshold. LT can only be tested at the lab via blood sampling but it can be tricky as some labs/professionals have different protocols and definitions (OBLA, MLSS, etc). LT scientifically defined is 1 mmol/liter above athlete’s exercise baseline which correlates with the point in which we basically switch from burning more CHO than fat for fuel and it is the consequence of your endurance capacity, it is not the cause. This can also be obtain pretty accurate via field testing and it is more trainable than VO2. LT it is a better performance predictor and the most important thing to track for endurance athletes as it provides us with a better idea of the different training adaptations achieved with training.
Next are the generally used training zones based on VO2 or LT. I am leaving Max HR because it is useless IMO.
Zone 1 - LTHR < 69%, VO2 - < 65%
Zone 2 - LTHR 69-83%, VO2 – 65-80%
Zone 3 - LTHR 84-94%, VO2 – 80-91%
Zone 4 - LTHR 95-105%, VO2 – 91-98%
Zone 5 - LTHR 106% >, VO2 – 98%>
BTW, your HR training zones wont changed much as you get fitter, your pace at that intensity will.
Don't know my HR for swimming and last time a tested R/B was over a year ago but for bike Z3 was 150-167 and run was155-173 both based on LT.
