Deepthi Velkur discusses the popular training method, Zone training for running.
Have you ever heard about the “zone”? That term has been thrown around fairly causally nowadays but let’s try and understand what it is.
The “zone” is a state of absolute focus that assists athletes across sports to perform at their peak potential. It’s the point when your mind fully processes only the thoughts and visuals needed to help you achieve your goal.
As an athlete, we often have one recurring question – “what’s the optimum training intensity level I need to be at?”.
Let’s try and break that down to understand it better. In training, there are pre-dominantly 3 key variables – Frequency, Duration, and Intensity.
To be able to achieve your best, you need a good training plan and a good training plan needs to have an amalgamation of different workout routines – some with shorter durations but higher intensity, some with longer times but a more relaxed intensity and so on. A mixed bag really and this variation brings about greater performance improvement.
Just so you know, high-intensity workouts are designed to help you improve speed and stamina while lower intensity workouts help achieve better endurance levels and overall toughness.
All of this leads to the next question – “how do I measure the intensity of my training”?
To answer that question, you first need to know what are training areas or intensity zones.
Intensity zones are the best indicators to show how hard your body is training during a workout.
For each of us, we have a personal resting heart rate, a minimum heart rate, and a maximum heart rate – between these values lie the different heart rate zones that correspond to the intensity of training and the benefits you reap from that training.
These heart rate zones are linked to your aerobic and anaerobic thresholds and the idea behind this type of training is to prepare your aerobic system without having to overstrain your muscular and skeleton systems.
There are different ways to identify your heart rate zones and the simplest one is to define them as percentages of your maximum heart rate.
So, how do you arrive at that magical heart rate zone?
There are various formulas to calculate your maximum heart rate(MHR). The MAF method promotes the 180 – formula in which you subtract your age from 180. You could further add or subtract 5 – 10 based on varying factors such as pregnancy, returning from injury or training competitively (subtracting for the former, adding for the latter).
The different heart-rate zones
There are 5 different heart-rate zones and every training plan can include workouts that cover each of these zones.
Here is a breakdown of what each zone means in terms of your heart rate and the benefits of training in each zone.
Zone 1: <70% of MHR: This is the low-intensity zone. Training in this zone helps in fast recovery and gets you prepared for training in the higher heart rate zones.
Zone 2: 65 -75% of MHR: This is a light zone primarily aimed at the aerobic base building. It is used for long easy runs and you can hold a conversation with your training partner. This zone helps in stabilizing your performance levels, improving basic endurance levels, training of fat metabolism and technique optimization. This zone is essential for every runner’s program.
Zone 3: 75-85% of MHR: This is a moderate zone that still keeps you in the aerobic range. It is effective for improving the efficiency of blood circulation in the skeletal muscles and the heart. Training in this zone is also used to stabilize your performance levels as well as training of glycogen metabolism and prepares you for higher intensity workouts.
Zone 4: 85-95% of MHR: This is the zone where the going gets tough, breathing will be difficult and your running in the anaerobic zone. Training at this intensity improves your speed endurance and the body uses carbohydrates as an energy source and you can withstand high levels of lactic acid in your blood for a longer duration.
Zone 5: 95-100% of MHR: In this zone, your heart and respiratory system will be working at their maximum capacity. The lactic acid builds up in the blood at this stage and after a few minutes, you are unable to continue at this intensity.
Each zone serves a purpose, and how much time you spend in each zone depends on your training goals. Intensity zones are used in sports because training at different intensities stresses your body in different ways, leading to different physiological adaptations and resulting in different benefits. If you’re just starting out or have only been training for some time or returning from injury, you probably shouldn’t train at a high intensity. If you’re a professional athlete, look into incorporating interval training into your training plan for peak performance.
Reaping the benefits of zone training
The biggest hurdle with heart rate training especially for advanced runners is holding back. People often feel they are doing something wrong if they are running at a slow pace – this often leads to frustration. The benefits of this training is to stay consistent, be patient and your pace will automatically improve.
Try and mix different workouts as variety is good, vary the intensity and duration of your training sessions and don’t be stuck running the same distance every time.
