polar power measurement
Power Measurement indicates the intensity of the cycling performance in watts. Power output provides an objective tool for tracking training progress very easily. The results can be analyzed and compared between cyclists and different exercises.
Where heart rate monitoring provides performance feedback with a short delay, power measurement enables accurate monitoring of performance output — instantly. This is especially beneficial during interval training, for instance, when feedback is required immediately.
Changes in performance due to weight fluctuations are also instantly discernible. Even small changes in aerodynamics are easily detected by measuring power output, since in comparable conditions, an increase of speed at the same power output level means better aerodynamics.
All in all, power measurement is a helpful and versatile tool for enhancing performance and keeping you in control. In addition to pedaling power, Polar Power Output Sensor measures Cycling Efficiency, Pedaling Index, LR Balance and Cadence.
