The table that badger1 just posted uses the term "peak mean power" which would be the highest power average over some unstated time period. Most likely the "peak" power in your article is also a peak mean power. Doubtless the term is well understood by cycling/sports medicine workers but it looks nonsensical to technologists from other fields when it is undefined and abbreviated to just peak power. I just looked over a recording from a recent two hour forty three minute ride I took. I had an average power of 179 W and while the 2kW absolute peak power I see in the plot (duration 1 second) is likely to be instrument error, I have many, many peaks in the 300 to 500 W range that last a few seconds each. I'm certainly no elite international class cyclist, I'm not even an elite McHenry County cyclist. My next door neighbor is 20 years younger than me and recently switched from competitive motorcycling to competitive bicycling after one too many brushes with death. I'm not even sure what he competes at, only that his wife says it is nice to go to his events now and not see an ambulance standing by at the ready. So bottom line, I'm not even the elite cyclist on my block!
