iRun 101

iRun 101 is the first installment of a two-part blog series highlighting the latest SPARK High School web-unit: iRun.


SPARK HS’s newest web-only addition, iRun, is a fitness-based running unit designed to promote personal health, fitness and running performance. Regardless of your students’ current fitness levels, iRun will inspire and support each individual student on the pathway to personal success.

iRun takes scientific training principles, fitness guidelines, and training methods and makes them easy to understand so that students can create individualized training programs, be active on a regular basis at an appropriate level, and achieve their personal fitness goals. Read on to learn more about the foundational components of the iRun unit:

Training Principles

A system for developing long-term changes and improvements in fitness levels:

  • Overload – adding resistance or increasing difficulty
  • Progression – rate of overload, resistance or difficulty
  • Individuality – personalized goals
  • Specificity – align program and exercises to personalized goals
  • Reversibility – use it or lose it

FITT Guidelines

Recommendations for providing details to a program:

  • Frequency – how often to workout
  • Intensity – how hard to workout
  • Time – how long to workout
  • Type – which method of training to use

Aerobic Training Methods

The approaches for applying training principles and FITT guidelines:

  1. Continuous – single activity, moderate intensity, extended period of time with no rest.
  2. Interval – single activity, short bursts of high intensity alternated with brief rest periods.
  3. Circuit – a series of different activities performed at high intensity, brief rest at end of series.
