So, are we saying that doing longish threshold efforts on one of these gives greater gains than on a fluid trainer? Watts are watts, Shirly?

The answer is - "it depends"
Lower ke trainers (ie traditional ones) replicate lower ke situations (ie hill climbs)
Higher ke trainers better replicate the requirements of lower gradients/tt'ingSo if your goal was the quickest time up Alpe D'Huez then you might want to stick with a low ke trainer. But if you are looking to improve your performance on the flat then a higher ke trainer makes sense.

A watt is a watt. But the production of that watt can be different.
And no. As danb said, it's not that simple. But I'd disagree about having a low kenetic energy trainer. That would trash my legs. As the pedal stroke would be different to on the road, recruiting different muscles.

The flywheel air resistance creates really good inertia. Search TTforum or google, been discussed in detail.
It gives a good road feel intertia. It's not quite road, but is good. So the muscle recruitment is near it would be on road.
I love mine. Works for me. And improvements on Turbo give me improvements on road. If I keep doing some efforts on road, so my muscles stay used to variable terrain and the torque change.
