A sports scientist is designing interval training programs targeting different energy systems. Which combination of intensity, work interval and recovery period would MOST effectively develop the glycolytic energy system?

  1. 95-100% maximum effort, 5-10 second work intervals, 3-5 minute recovery periods
  2. 75-85% maximum effort, 3-5 minute work intervals, 1-2 minute recovery periods
  3. 85-95% maximum effort, 30-90 second work intervals, 1-3 minute recovery periods
  4. 60-75% maximum effort, 10-20 minute work intervals, 2-3 minute recovery periods

Show Worked Solution
  • C is correct:
    • The glycolytic (lactic acid) system is optimally trained using 85-95% intensity with 30-90 second work intervals and 1-3 minute recovery periods.
    • This creates the optimal stimulus for lactate production and clearance adaptations.

Other Options:

  • A is incorrect: 5-10 second intervals with long recovery primarily target the ATP-PCr system, not the glycolytic system.
  • B is incorrect: 3-5 minute work intervals with shorter recovery shifts training toward the aerobic system rather than focusing on glycolytic development.
  • D is incorrect: 60-75% intensity with 10-20 minute intervals represents aerobic endurance training that won’t effectively develop the glycolytic system.
