Effects and individual response of continuous and interval training on adiponectin concentration, cardiometabolic risk factors, and physical fitness in overweight adolescents

Abstract

ObjectiveStudy aimed to evaluate the effect and individual responsiveness after 12-weeks of high-intensity interval training (HIIT) and moderate-intensity of continuous training (MICT) on adiponectin, cardiometabolic risk factors and physical tness in overweight adolescents. MethodsParticipated 52 adolescents, both sexes, 11 and 16 years-old: HIIT (n = 13), MICT (n = 15) and control group (CG, n = 24). Body mass, height, waist circumference (WC), fat mass (FM), fat-free mass (FFM), blood pressure, high-density lipoprotein (HDL-c), low-density lipoprotein (LDL-c), triglycerides, insulin, adiponectin, and C-reactive protein (CRP) were evaluated. Body mass index z-score (BMI-z), waist-to-height ratio (WHtR), insulin resistance and insulin sensitivity were calculated. Resting heart rate (HR rest ), peak oxygen consumption (VO 2peak ), right handgrip strength (HGS-right), left handgrip strength (HGS-left) and abdominal resistance (ABD) was evaluated. HIIT session lasted around 35min and MICT of 60min of exercises on stationary bicycle, three times a weekday for 12-weeks. ANOVA, effect size, and prevalence of responders were used for statistical analysis. ResultsHIIT reduced BMI-z, WHtR, LDL-c and CRP, while increased of physical tness. MICT reduced HDL-c, while increased of physical tness. CG reduced FM, HDL-c, and CRP, while increased FFM and HR rest . Frequencies of respondents in HIIT were observed for CRP, VO 2peak , HGS-right and HGS-left.Frequencies of respondents in MICT were observed for CRP and HGS-right. Frequencies of no-respondents in CG were observed for WC, WHtR, CRP, HR rest and ABD. ConclusionInterventions with exercises were effective to adiposity, metabolic health, and physical tness improvements. Individual responses were observed in in ammatory process and physical tness, important changes in overweight adolescent's therapy.

High intensity interval training vs. moderate intensity continuous training on aerobic capacity and functional capacity in patients with heart failure: a systematic review and meta-analysis

“…Furthermore, it has been documented ( 44 ) that HIIT exhibits superior efficacy in reducing risk factors associated with skeletal sarcopenia and mitigating the morphological and functional deterioration linked to this condition, surpassing the benefits of resistance training. Notably, compared to the MICT group, the HIIT group experienced a significant reduction in BMI and a substantial increase in peak VO 2 , according to the study by Tadiotto et al ( 45 ). Based on the results of the present meta-analysis, we therefore hypothesize that HIIT is preferable to MICT for increasing peak VO 2 in HFrEF patients with a low.…”

Effects of different types of exercise intensity on improving health-related physical fitness in children and adolescents: a systematic review

“…One study scored below 4. Blinding techniques ranged from 0 to 3 in this study, with only one study scoring 3 and four scoring 1; Fifteen studies scored 0. www.nature.com/scientificreports/ Tadiotto et al conducted a 12-week HIIT and MIIT intervention study and found significant reductions in (body mass index) BMI-z, (waist-to-height ratio) WHtR, and LDL-c in HIIT 28 . Benson et al compared the effects of high-intensity progressive resistance training (PRT) on body composition in obese children and showed that an 8-week PRT intervention resulted in significant improvements in adiposity, percentage body fat, and body mass index 34 .…”

Effects of different types of exercise intensity on improving physical health in children and adolescents: A systematic review

“…Seven studies were interventions with interval training of varying intensities. Four studies have shown that high-intensity interval training (HIIT) is effective in reducing visceral fat, while moderateintensity interval training (MICT) reduces body fat percentage (BF%)21,24,40,43 . One study showed that high-intensity interval training had a moderate effect on improving body composition in adolescents41 .…”

“…One study showed that high-intensity interval training had a moderate effect on improving body composition in adolescents41 . The study by Tadiotto et al showed that high-intensity interval training reduced body mass index, and waist-toheight ratio, and improved physical tness21 . In addition, four studies used aerobic exercise of varying intensities.…”
