intervals versus repetitions wrote:
It is understood in the sport that the 'interval' is the time between repetitions.
Maybe that's true in your particular corner of the sport, but it's far from universal.
Here's a quote from Once a Runner, published in 1978:
"An interval workout," Cassidy once explained to a sportswriter, "is the modern distance runner's equivalent of the once popular Iron Maiden..."
Another one:
"An interval workout is simply a series of fast runs of a specified distance in a specified time with a specified rest."
If you read on, it's clear he's using "interval" to refer to the hard running, not the recovery:
"After the shock of the first several quarters, Cassidy settled into the pleasant, nearly comfortable rhythm of the workout, where each interval, though difficult, felt very much like the one before and the one to follow."
That's how I've used the term in the 30+ years I've been running intervals, and the same goes for every workout group I've been part of. So don't blame Jack Daniels!
