What is interval training?

by Ella Whiteley 17. July 2009 06:45
Interval training guides runners in developing workouts that are tailored to their particular situations. Interval training refers to workouts in which hard running efforts of prescribed distances or time are repeated with intervals of rest between the repeated hard efforts.

There are three main reasons that interval training is done:

  1. Intervals are used to increase anaerobic threshold levels. By repeating sustained hard efforts at near anaerobic condition, the runner improves his ability to run hard without going into oxygen debt.
  2. Interval training also increases a runner's endurance. This means that the runner can continue at a certain pace for an extended period of time.
  3. Finally, interval training builds muscle strength. Typical distance running exercises the leg muscles in a certain range of motion, with the focus on slow-twitch fibres. By running at faster speeds, the runner exercises all leg muscles and improves flexibility during running, both of which will mean improved muscle performance in races. This makes running at a race pace easier and improves top speed for sprint finishes.
