• Movement of the upper body muscles (including arms) produces an electrical signal (muscle artifact) that can interfere
with pulse detection. Slight hand movement while in contact with the sensors can also produce interference.
• Calluses and hand lotion may act as an insulating layer to reduce the signal strength.
• Some Electrocardiogram (EKG) signals generated by individuals are not strong enough to be detected by the sensors.
• The proximity of other electronic machines can generate interference.
If your heart rate signal ever seems erratic after validation, wipe off your hands and the sensors and try again.
Heart Rate Calculations
Your maximum heart rate usually decreases from 220 Beats Per Minute (BPM) in childhood to approximately 160 BPM by
age 60. This fall in heart rate is usually linear, decreasing by approximately one BPM for each year. There is no indication
that training inuences the decrease in maximum heart rate. Individuals of the same age could have different maximum
heart rates. It is more accurate to nd this value by completing a stress test than by using an age related formula.
Your at-rest heart rate is inuenced by endurance training. The typical adult has an at rest heart rate of approximately 72
BPM, whereas highly trained runners may have readings of 40 BPM or lower.
The Heart Rate table is an estimate of what Heart Rate Zone (HRZ) is effective to burn fat and improve your cardiovas-
cular system. Physical conditions vary, therefore your individual HRZ could be several beats higher or lower than what is
shown.
The most efcient procedure to burn fat during exercise is to start at a slow pace and gradually increase your intensity un-
til your heart rate reaches between 60 – 85% of your maximum heart rate. Continue at that pace, keeping your heart rate
in that target zone for over 20 minutes. The longer you maintain your target heart rate, the more fat your body will burn.
The graph is a brief guideline, describing the generally suggested target heart rates based on age. As noted above, your
optimal target rate may be higher or lower. Consult your physician for your individual target heart rate zone.
Note: As with all exercises and tness regimens, always use your best judgment when you increase your exercise time
or intensity.
