Concurrent and aerobic exercise training promote similar benefits in body composition and metabolic profiles in obese adolescents

Abstract

BackgroundThe prevalence of obesity in pediatric population is increasing at an accelerated rate in many countries, and has become a major public health concern. Physical activity, particularly exercise training, remains to be a cornerstone of pediatric obesity interventions. The purpose of our current randomized intervention trial was to compare the effects of two types of training matched for training volume, aerobic and concurrent, on body composition and metabolic profile in obese adolescents. Thus the aim of the study was compare the effects of two types of training matched for training volume, aerobic and concurrent, on body composition and metabolic profile in obese adolescents.Methods32 obese adolescents participated in two randomized training groups, concurrent or aerobic, for 20 weeks (50 mins x 3 per week, supervised), and were compared to a 16-subject control group. We measured the percentage body fat (%BF, primary outcome), fat-free mass, percentage of android fat by dual energy x-ray absorptiometry, and others metabolic profiles at baseline and after interventions, and compared them between groups using the Intent-to-treat design.ResultsIn 20 weeks, both exercise training groups significantly reduced %BF by 2.9-3.6 % as compare to no change in the control group (p = 0.042). There were also positive changes in lipid levels in exercise groups. No noticeable changes were found between aerobic and concurrent training groups.ConclusionsThe benefits of exercise in reducing body fat and metabolic risk profiles can be achieved by performing either type of training in obese adolescents.Trial registrationRegistration number: RBR-4HN597.

Effects of Concurrent Strength and Aerobic Training on Blood Glucose Homeostasis and Lipid Profile in Females with Overweight and Obesity

“…Patel et al, after eight weeks of resistance training on males with obesity aged 10 -12 years, observed no decreases in lipid profiles (18). Also, consistent with the current study findings for LDL-c and TC, similar results were found for concurrent training after 20 weeks in adolescents with obesity (20). In contrast, the current study results were in disagreement with those of Antunes et al, Monteiro et al, and Sung et al In the study by Antunes et al, samples included 25 adolescents with obesity aged 12 -15 years.…”

“…It was reported that just the female group showed significant decreases in LDL and TC after 20 weeks. Training protocol in their study was similar to that of the current study (18,20,30). In a study on 82 children with obesity aged eight to eleven years, Sung et al, observed significant reductions in TC and LDL-C after a six week resistance training (35).…”

“…Also, the effect of concurrent training on glucose homeostasis showed improvement (17) or no change (19). According to studies, concurrent exercise has better performance than resistance and aerobic trainings alone in promoting body composition (12,20). On the other hand, two recent metaanalysis in adults with obesity and patients with type 2 diabetes revealed that concurrent exercise was the best method to enhance anthropometric indicators of adiposity (21) glycemic control, and blood lipids (22) as compared with aerobic or resistance alone.…”

Concurrent aerobic plus resistance exercise versus aerobic exercise alone to improve health outcomes in paediatric obesity: a systematic review and meta-analysis

“…Nine studies recruited obese youth exclusively;24 27–34 whereas, the rest targeted both overweight and obese children 25 26 35. Most studies (n=8) included adolescents (aged 13–18 years),24–32 35 one included only children,33 and one enrolled both children and adolescents 34. All studies included boys and girls.…”

“…Monteiro and colleagues [106] aerobic exercise only, and this reduction was 3.5% and 3.9% respectively. Moreover, consistent results were also found in the lipid profile, with reduction in circulating levels of TG and VLDL and increase in HDL levels.…”
