This is a quote from G. Lemond:
"It's amazing how little real knowledge there is in cycling about power output. Everybody talks about heart rate, and heart rate is important. But when you look at performance, it's real simple. It's how many watts you produce. I know riders who say, 'I can ride for 30 minutes at 190 beats per minute.' So what? You can ride at 190 bpm and still be putting out only 200 watts. A heart-rate monitor alone is never the best measure in cycling. There's wind, hills, drafting. You never can really tell how you're riding. In February, I got sick. I could tell I was getting sick right away. I could tell something was going on before I got sick. With a heart-rate monitor, you could train, and your heart rate would be high, and you would think things were fine. My heart rate was fine, but I could see my power output drop dramatically. Your performance doesn't exactly match your heart rate like everybody thinks. I've ridden at 180 bpm for 30 minutes in a climb during race, and I was at 330 watts of power output the who way up to the climb. For me, that was poor. The next day, we came up the other side of the same mountain, and I produced 60 watts more at a lower heart rate."
Based on this comment:
What's the best training technique to develop/gain more Power Output (wattage) for the average roadie ??
Has anybody underwent an specific training to do this in the past?
My gut feeling is that weight training has a lot to do with this.
