AB  - BACKGROUND: Current evidence of metabolic health benefits of high-intensity 
      interval training (HIIT) are limited to longer training periods or conducted in 
      overweight youth. This study assessed 1) fasting and postprandial insulin and 
      glucose before and after 2 weeks of HIIT in healthy adolescent boys, and 2) the 
      relationship between pre intervention health outcomes and the effects of the HIIT 
      intervention. METHODS: Seven healthy boys (age:14.3 +/- 0.3 y, BMI: 21.6 +/- 2.6, 3 
      participants classified as overweight) completed 6 sessions of HIIT over 2 weeks. 
      Insulin resistance (IR) and blood glucose and insulin responses to a Mixed Meal 
      Tolerance Test (MMTT) were assessed before (PRE), 20 h and 70 h after (POST) the 
      final HIIT session. RESULTS: Two weeks of HIIT had no effect on fasting plasma 
      glucose, insulin or IR at 20 h and 70 h POST HIIT, nor insulin and glucose 
      response to MMTT (all P > 0.05). There was a strong negative correlation between 
      PRE training IR and change in IR after HIIT (r = - 0.96, P < 0.05). CONCLUSION: 
      Two weeks of HIIT did not elicit improvements to fasting or postprandial glucose 
      or insulin health outcomes in a group of adolescent boys. However the negative 
      correlation between PRE IR and improvements after HIIT suggest that interventions 
      of this type may be effective in adolescents with raised baseline IR.
