We recommend that individuals with pacemakers do not use a heart rate monitor. In fact, the radio transmission system could disrupt the signal.
Your heart rate is measured using a chest strap. This comprises two electrodes and a transmitter.
When your heart beats, it creates a weak electric field. This is captured by the electrodes then transmitted to your watch by the belt's transmitter.
If it takes a long time to locate a signal or if the readings appear inconsistent:
1 - Check that your belt is correctly positioned on your body. Also check that it's the right way round.
2 - Check that you have dampened the sensors on your belt.
3 - The HR signal can be affected by electromagnetic interference (power lines, railway, computers etc. When using your heart rate monitor, ensure that you stay away from these kinds of interference
4 - Check that the battery is still charged. 0
To determine your target heart rate when exercising, firstly you need to identify your maximum heart rate.
The maximum heart rate (max HR) is the maximum rate at which a human heart should ideally beat.
This figure depends on age and can be estimated using the following formula: MaxHR = 220 - age To identify an individual's maximum heart rate more accurately, you're advised to undergo a maximum heart rate test, administered by a doctor.
Once you've identified your MaxHR, you can decide on a target heart-rate zone, for your workout, depending on your goal. WARM-UP/RECOVERY. 50 to 60% of your max HR The blue zone corresponds to a moderate effort. Ideal for a gentle warm up at the beginning of your session and for an active end of session cool down to help remove waste produced by your muscles during exercise.
BASIC STAMINA 60 to 70% of your MaxHR Basic stamina is essential for all sportsmen and women. It is particularly good for the health as well as improving your performance during long exercise sessions. Exercise in this zone for over 45 minutes in order to gently exercise your heart, improve the blood supply to your muscles and train your muscles to draw on your fat reserves. ENDURANCE
TRAINING 70 to 80% of your max HR In this zone you are training just below your anaerobic threshold: the effort is intense but your body is still able to provide enough oxygen to maintain this effort over time. Active endurance training will encourage your muscles to draw on sugar supplies, present in your muscle fibres, more effectively when exercising and store this sugar more effectively when at rest. This type of training must be done less frequently than basic endurance.
GENTLE RESISTANCE 80 to 90% of your max HR Your body is unable to supply the muscles with sufficient oxygen to meet their needs: this is the anaerobic or resistance threshold. This zone helps to improve your performance and your endurance if you exercise in short repeated bursts (intervals). Your muscles will work more effectively and your heart beat more regularly as you approach the threshold.
HEAVY RESISTANCE > 90% of your MaxHR
This zone represents intense exercise. This type of exercise must only be done for very short intervals. It helps to increase your anaerobic threshold and therefore improve your performance and your endurance. The red zone is reserved for sportsmen and women with good self-knowledge, who are really seeking to improve their performance levels.
A heart rate monitor is an electronic device which measures your heart rate using a chest strap. The signal is transmitted wirelessly from the strap to your watch and the heart rate reading displayed in BPM (Beats Per Minute).
Your heart rate is one of the best ways of instantly assessing your fitness level.
By monitoring your heart rate, you can easily determine the effect of exercise on your body.
This allows you to better manage your workout and achieve your goals more easily.
You can access the stopwatch by pressing the"Play/Pause" (top right) button while the device is searching for HR signal. The watch will go directly to activity mode.
To access the settings and activity menu, you need to hold down the "back" button (top left).
Your heart rate monitor does not have a coded signal and may be disrupted by signals from other heart rate monitors nearby. If this is the case, you're advised to choose a heart rate monitor with a coded signal system.
- Cleaning the watch :
In order to keep your watch glass clean, it is advisable to clean it with a damp cloth.
In order to optimize the performance of the heart sensor, it is also advisable to clean it regularly with a damp cloth.
You can also clean the charging connector with a dry toothbrush.
