“…Similarly, an exploratory study of a 10 week school based HIIT programme for healthy adolescent showed no changes to glucose [44]. In a 5 week HIIT intervention consisting of 10 × 1 min sprints 3 x /week Van Bijon and colleagues [45] reported a trend towards improvement for fasting glucose, but not insulin in healthy 10-13 year olds. In contrast, studies investigating the effectiveness of HIIT in overweight or obese participants over 12 weeks [13][14][15]17] have shown improvements to fasting glucose, insulin and HOMA-IR.…”

Background This study examined whether improvements in fasting and postprandial [insulin], [glucose] and aerobic fitness are possible after two weeks of high-intensity interval training (HIIT) in adolescent boys. Methods Seven boys (14.3 ± 0.3 y) completed 6 sessions of HIIT over two weeks. Homeostatic model assessment of insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), fasting glucose:insulin ratio (FGIR) and blood [glucose] and [insulin] responses to a Mixed Meal Tolerance Test (MMTT) were assessed before (PRE), and 20 h and 70 h after (POST) the final HIIT session. Maximal oxygen uptake (VO2 max) was assesed PRE and 70 h POST. Results Compared to PRE, two weeks of HIIT had no effect on fasting plasma [glucose] or [insulin] or HOMA-IR at 20 h and 70 h POST. However, a strong negative correlation was observed between PRE training HOMA-IR, QUICKI and FGIR, and change in HOMA-IR, FGIR and QUICKI at 20 h POST (r =-0.96, 0.969 and 0.826 for HOMA-IR, QUICKI and FGIR respectively all P<0.05). Plasma [insulin] and [glucose] area under the curve in the postprandial period following the MMTT were unchanged 20 h and 70 h POST compared to PRE. Conclusion Two weeks of HIIT did not elicit improvements to fasting or postprandial glucose or insulin health outcomes or aerobic fitness in a group of adolescent boys. Interventions of this type may, however, be effective in adolescents with raised baseline IR.

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 two 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 two 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.

“…Another group of researchers found a significant decrease in waist circumference and heart rate at rest in obese children using the combination of HIIT + MICT protocols. However, implementation of HIIT protocols has a greater effect on lowering fasting glucose, c-reactive protein and increasing VO2max relative to MICT and HIIT + MICT [21]. Younger obese pupils aged 7-9 years participated in a research of the effectiveness of the implementation of HIIT protocols on weight loss.…”

Analysis of high-intensity physical activity biological feasibility within the framework of children health training

Epidemiological surveys reflect a negative trend in functional indicators for children’s physical health. In recent surveys it is experimentally proved that unlike other methods of training, high-intensity interval training (HIIT) produces prevailing positive effect onto the indicators of physical and functional condition of children with poor health. However, the review of studies suggests that the stated idea turns to be controversial. There is the evidence of possible negative effects of intense physical activity due to the low level biological reliability of adaptation mechanisms and other anatomical and physiological characteristics of children. Therefore, it is necessary to provide a scientifically based conceptual model of timeline for children’s health training in which the central health impetus will be HIIT.
