3.16. GPS accuracy and power saving
The GPS fix rate determines the accuracy of your track - the shorter the interval is between
fixes, the better the track accuracy is. Each GPS fix is recorded in your log when recording an
exercise.
The GPS fix rate also directly aects battery life. By reducing GPS accuracy, you can extend
the battery life of your watch.
The GPS accuracy options are:
•
Best: ~ 1 sec
fix rate
•
Good: ~ 60 sec fix rate
You can change GPS accuracy from the sport options in your watch or in Suunto app.
Whenever you navigate a route or a POI, the GPS accuracy is automatically set to Best.
NOTE: The first time you exercise or navigate with GPS, wait for the watch to acquire a
GPS fix before starting. This may take 30 seconds or more depending on conditions.
3.17. Intensity zones
Using intensity zones for exercising helps guide your fitness development. Each intensity
zone stresses your body in dierent ways, leading to dierent eects on your physical fitness.
There are five dierent zones, numbered 1 (lowest) to 5 (highest), defined as percentage
ranges based on your maximum heart rate (max HR), pace or power.
It is important to train with intensity in mind and understand how that intensity should feel.
And don't forget, regardless of your planned training, that you should always take time to
warm up before an exercise.
The
five dierent intensity zones used in Suunto 5 are:
Zone 1: Easy
Exercising in zone 1 is relatively easy on your body. When it comes to fitness training, intensity
this low is significant mainly in restorative training and improving your basic fitness when you
are just beginning to exercise, or after a long break. Everyday exercise – walking, climbing
stairs, cycling to work, etc. – is usually performed within this intensity zone.
Zone 2: Moderate
Exercising at zone 2 improves your basic
fitness level eectively. Exercising at this intensity
feels easy, but workouts with a long duration can have a very high training
eect. The majority
of cardiovascular conditioning training should be performed within this zone. Improving basic
fitness builds a foundation for other exercise and prepares your system for more energetic
activity. Long duration workouts at this zone consume a lot of energy, especially from your
body’s stored fat.
Zone 3: Hard
Exercising at zone 3 begins to be quite energetic and feels like pretty hard going. It will
improve your ability to move quickly and economically. In this zone, lactic acid begins to form
in your system, but your body is still able to completely
flush it out. You should train at this
intensity at most a couple of times per week, as it puts your body under a lot of stress.
Zone 4: Very hard
