Heart Rate Teaches Control
The large majority of amateur runners we havetested in our labare training too fast on a regular basis, compromising their development by living in an ‘intensity grey zone’.
Monitoring heart rate, while often frustrating to begin with, teaches you how to control your ego, your effort, and how your body is responding to the stress of training. Over time, your innate ability to judge intensity (feel) improves and you become less reliant on your monitor.
When done right, you’ll begin to understand how your body responds to various stressors and conditions and you will know the pace you are producing, how it feels and what your heart rate is at any given time. This ‘dialled in’ sense of self should be the goal for all athletes.
Heart Rate Shows You How Your Body Responds To Different Situations
As you monitor your heart rate on a regular basis, you will begin to see what types of stress have the biggest effect on your heart rate. You’ll notice how caffeine, a hot day, a poor night’s sleep or a sh*tty day at work affects your heart rate and over time you’ll be able to make smarter decisions in relation to your training and recovery.
The Bad: The Cons Of Training By Heart Rate
Heart Rate Lags
Unlike pace which responds immediately to changes in intensity just like the speedometer in your car, heart rate is often accompanied by a lag. When you increase the intensity suddenly, it takes some time for heart rate to climb to the level that it will ultimately plateau. This can make heart rate unreliable during short intense intervals.
Heart Rate Drifts
Heart rate drift refers to the natural increase in heart rate despite little or no change in pace. This drift is connected with an increase in core temperature and body water losses, resulting in an elevation of heart rate. While this drift happens under most conditions, it is significantly worse in hot and humid climates like those that we face in Singapore. Pay close attention to your hydration to slow the rate at which your heart rate drifts.
Heart Rate Monitors Can Be Unreliable
While the technology used in heart rate monitors continues to improve, there are still situations where monitors can display inaccurate readings and batteries can die. This becomes less of a problem the more you run with a heart rate monitor and the more you understand your body. If your monitor falters, your dialled in sense of feel will help to see you through.
You Need To Know Your Zones
The best way to establish heart rate training zones is to dotesting in a lablike what we offer here in Singapore. The downside of lab testing is that it is relatively expensive and not readily available for many people.
There are many heart rate formula’s around, most of which are terrible and many others that are complex. We use a modified version ofPhil Maffetone’s 180 Formulaas the foundation for our heart rate zones in our online training programme. We use this formula because when we tested many of the common heart rate formulas against our client lactate results, this one consistently came up as the most accurate.
In Closing
While there are a few important cons to training by heart rate, I believe the pros outweigh these cons.
When you are balancing a job, family and social life with training, having a good understanding of how your body is responding to stress is crucial to making smart decisions that support your ability to improve and stay healthy.
When used in conjunction with pace, you get the best of both worlds and your ability to feel your training will also improve as a result.
