Is there any evidence power meters enable you to train more effectively?
An over reliance on power output data may not be the best approach. You can train very effectively without a power meter.
I really would like to see some evidence. Much is said about training with power and data analysis and power meters are very expensive. Is it really too much to ask for some evidence?
I refer you to my previous post, which you seem to have missed.

It would require more time, more athletes, more types of training and more controlled variables, and more measures of changes in performance (30s, 1min, 5min, 20min etc). And it's not power meters alone that make training more effective - it's the athlete or coaches ability to interpret the power data and adjust the training as necessary. How can you control that variable in a study? This is why you are very unlikely to find a decent scientific study that shows power meters to be superior to HR monitors. It would cost too much, it would take a long time and it would probably be too complicated and difficult to control.
It's not as if there is a big power meter company with millions of pounds to spend on funding such studies in the way that Gatorade funds studies into the benefits of sports drinks (the results of which, strangely, always seem to be in their favour...)
If you knew anything about scientific research you'd have worked that out yourself already...
Unless someone is trying to force you to buy a power meter, or you are trying to decide to buy one for yourself, I don't see what the problem is.
I know that I don't need one myself. However, I want one because I'd like to be able to pace my efforts better, record how much work I've been doing, and measure my improvements. I want hard data instead of guesswork. Having had a keen interest in science from school age, studying it at university and (very briefly) working in analytical chemistry, power measurement appeals to me. I don't need evidence or dogmatic belief that it will or won't work better than training by RPE - because that's not the point of it for me.
