Abstract
It is estimated that almost 10% of children of school age worldwide have increased body weight and subsequently higher risk for developing different chronic conditions. One quarter of children are obese, some have multiple risk factors for diabetes type 2, cardiovascular diseases and other comorbidities development before and during adulthood. Prevalence of obesity is dramatically higher in developed countries but is also on the rise in other parts of the planet. Clinical management of overweight children demands time, financial resources, multidisciplinary team and individualized approach. In this paper the results of research conducted in Pediatric Clinic at University Clinical Hospital Sestre Milosrdnice, Zagreb are presented. The goal was to search for differences in effects of high intensity interval training (HIIT) combined with dietary regime and conventional aerobic training (CAT) and diet on aerobic capacity in obese children measured indirectly using submaximal test were compared. There were 15 participants in experimental and control group respectfully, median 13,93 (SD = 1, 74) years of age, 50 % of them male. Average participant body mass index (BMI) 34,83±3,95. The average controlled daily dietary intake was 1700 kcal. Results show statistically significant difference between initial and final measurement in almost all variables; body weight (t(29) = 19,11, p < 0,001), BMI (t(29) = 17,73, p < 0,001), VO2max (t(29) = -9,88, p < 0,001), modified Astrand test time (t(29) = -10,29, p < 0,001) in both groups. The somewhat better results were also observed in experimental group in VO2max values estimated by Astrand test (p=0,045) as opposed to control group but probably due to small sample size the differences in other aerobic capacity imation variables was not statistically significant. HIIT was not less efficient than CAT in aerobic capacity improvement in obese children and might represent a good alternative to more traditional training methods in such children, especially as childern often perceive it as more interesting.
