Exercising at zone 4 will prepare your system for competition type events and high speeds.
Workouts in this zone can be performed either at constant speed or as interval training
(combinations of shorter training phases with intermittent breaks). High-intensity training
develops your fitness level quickly and eectively, but done too often or at too high intensity
may lead to overtraining, which may force you to take a long break from your training
program.
Zone 5: Maximal
When your heart rate during a workout reaches zone 5, the training will feel extremely hard.
Lactic acid will build up in your system much faster than it can be removed, and you will be
forced to stop after a few minutes at most. Athletes include these maximum-intensity
workouts in their training program in a very controlled manner,
fitness enthusiasts do not
require them at all.
3.17.1. Heart rate zones
Heart rate zones are defined as percentage ranges based on your maximum heart rate (max
HR).
By default, your max HR is calculated using the standard equation: 220 - your age. If you
know your exact max HR, you should adjust the default value accordingly.
Suunto 5 has default and
activity-specific HR zones. The default zones can be used for all
activities, but for more advanced training, you can use specific HR zones for running and
cycling activities.
