The 22 minute HIIT took place during a regular PE lesson and consisted of two rounds of 4 x 30 second sprints. Foods were offered at a regular school lunch immediately following HIIT and SED and were matched between conditions. All food was covertly weighed before and after the meal. Hunger, fullness and prospective consumption were reported immediately before and after HIIT/SED, using visual analogue scales. Heart rate was higher during HIIT than SED

Homeostatic and neurocognitive control of energy intake in response to exercise in pediatric obesity: a psychobiological framework

“…recently investigated the appetite and EI response to a 22‐min HIIE physical education session in normal‐weight 9 to 11‐year‐old children . Their results reinforce the conclusions of the above cited meta‐analysis finding no modification of appetite feelings, energy or macronutrient intake after HIIE in normal‐weight kids . In a recent study from our research group, we tested the effect of such a HIIE session on EI and appetite in 12 to 15‐year‐old youth with obesity .…”

“…Interestingly, while High Intensity Interval Exercises (HIIE) and Sprint Interval Trainings are actually advocated and promoted for their time‐efficient nature and beneficial effects on adiposity and cardio‐metabolic health, Morris et al . recently investigated the appetite and EI response to a 22‐min HIIE physical education session in normal‐weight 9 to 11‐year‐old children . Their results reinforce the conclusions of the above cited meta‐analysis finding no modification of appetite feelings, energy or macronutrient intake after HIIE in normal‐weight kids .…”

Classroom-Based Micro-Sessions of Functional High-Intensity Circuit Training Enhances Functional Strength but Not Cardiorespiratory Fitness in School Children—A Feasibility Study

“…Since children spend 40% of their waking hours in the school (14) it seems the school setting is ideal to implement PA promotion. In this context HIIT was recently applied within physical education (PE) classes of children (15, 16) and adolescent students (17, 18) to enhance CRF [determined by a shuttle run (17, 18) and 6 min walking test (16)]. Additionally, HIIT not only improved CRF but also functional strength when applied for relative short periods of 7–10 weeks with 1–3 sessions/week (19, 20).…”
