An athlete performed two different training methods on separate days. The table shows the physiological and performance results from each session.

Which of the following BEST identifies Methods X and Y?

  1. Method X is HIIT, Method Y is continuous training
  2. Method X is continuous training, Method Y is HIIT
  3. Method X is SIT, Method Y is HIIT
  4. Method X is HIIT, Method Y is SIT

Consider Option D: 

  • Method X shows high (but not very high) blood lactate, moderate EPOC, and longer time to exhaustion (20 minutes), consistent with HIIT which typically involves high but not maximal intensity.
  • Method Y shows very high blood lactate, high EPOC, and shorter time to exhaustion (15 minutes), consistent with SIT which involves supramaximal intensity and creates greater physiological stress per unit time.

Other Options:

  • A is incorrect: Continuous training would produce lower blood lactate levels than HIIT, not higher as shown for Method Y.
  • B is incorrect: Continuous training typically produces moderate lactate levels and has longer time to exhaustion than HIIT, inconsistent with the data shown.
  • C is incorrect: SIT typically produces higher blood lactate and EPOC than HIIT due to its supramaximal intensity, so this order would be inconsistent with the physiological markers shown in the table.
