continuous power at a Tacx Flow / I-Magic training role and the Polar power meter power

I'm still in the rest week to my training plan . After I like here was reported not granted the Polar Power Output Sensor to test out, I tried this this week in my training room .

This is going to no comparison of the accuracy of the performance measurement between a Tacx I-Magic trainer and a Polar Power Output Sensor . I am well aware that both relative to a reference power meter, such as the SRM Training System , with almost certainly have their differences. To train on power, it is very important that the performance is constantly measured in the same conditions, and uncontrolled or irreproducible varies.
It is however interesting that I compared to a reference power meter, such as the SRM Training System constant lying about a few percent above or below the reference value. To train Power is then still possible if I had done my performance tests such as the fitness baseline testing , or Threshold Test also tested with the training device. can

a Polar Power Output Sensor to test on a trainer to measurement problems and lack of detail in certain gear combinations. The system then responds sensitively to interference and vibrations that are not as in free driving.

Also see Robert Chung had "Why it's important to check power meter accuracy"

the test I described in the above link with my Tacx I-Magic role and mounted Polar Power Output Sensor performed in parallel. The test itself is very simple.

" One constant runs 30 Km / h that switches through all gear combinations, the optimal result is when the service will also have the tested period constant. "

That works for the Tacx I-Magic training role very well, not so with Polar Power Output Sensor !


have In this test, I switched from 39x11 39x25 up high and then switched from 53x25 down. With the Tacx I-Magic role you can see how beautiful is the constant. The only exception, the combinations, where the cadence was almost impossible to control. The Polar Power Output Sensor contrary, we see clear differences between the small chain ring (left) and the big chain ring (right). While the performance of the small chain ring to the combination 39x11 would not be tolerated, prevail when using the big chainring to large variations.

might Looking at these graphs I now actually save the text. I will do some tests. I currently have my exercise bike back to my role excited and I'm proud of my Tacx I-Magic training role. The training on the performance seems so pointless after all not so.
