Heart rate monitor chest strap
LoadHeart rate sensor worn on the chest, more accurate than wrist optical sensors during intense effort.
A chest strap monitors the heart's electrical activity (simplified ECG) and transmits via Bluetooth or ANT+ to your watch or bike computer. It is significantly more accurate than wrist optical sensors, especially during high-intensity efforts, climbing, or in cold conditions (low skin perfusion). Essential for reliable HR-zone training.
In TriPaced:
In TriPaced, the heart rate zones used in your sessions are calculated from your FCmax and resting HR. For best accuracy, use a chest strap (not optical) during threshold or VO2max sessions used to calibrate these zones.
