Efeito do treinamento concorrente e destreinamento sobre o biomarcador anti-inflamatório e níveis de condicionamento físico em crianças obesas

Abstract

Objective: To examine the effect of 12 weeks of (3 days/week) concurrent training and 4 weeks of detraining on serum adiponectin concentrations and physical fitness levels in obese boys without dietary intervention. Methods: 24 healthy boys, 11-13 years old with body mass index >28 voluntarily participated in the study. They were divided into two groups, experimental (n = 12) and control (n = 12). results: Adiponectin concentrations after 12 weeks presented significant decline in both experimental and control group compared with the baseline (p < 0.05). VO 2 peak, flexibility, strength, endurance of sit-ups and agility significantly increased in the experimental group compared with the control group (p < 0.05). It was shown that after a 4-week detraining, serum adiponectin did not significantly change in the experimental group and that beneficial physical fitness was gradually decreased. Conclusion: Our results suggest that the beneficial effects of exercise training on physical fitness are temporary. Since the process of adaptation is reversible, it seems that adiponectin concentrations were inevitably affected by morphological and hormonal changes that occurred during puberty in boys.

Effects of Concurrent Training on Muscle Fibers of Wistar Rats Submitted to Standard and Hypercaloric Diets

“…It is probable that the experimental diet interfered more in muscle adaptation than the CT protocol, since animals fed the hypercaloric diet (OS and OE) demonstrated a significant increase (p <0.05) compared to the other groups of animals (GS and GE). Fazelifar et al (2013), observed the effects of CT in obese children. It was found that the protocol used was sufficient to develop increased physiological variables of VO2 max, flexibility and strength.…”

The Role of Adipokines in Health and Disease

“…The different studies carried out in children or adolescents with obesity indicate that the adiponectin response to exercise depends on the different hormonal changes associated with sex in the pre-or postpubertal age [19]. In this sense, Fazelifar et al [301] observed a decrease in adiponectin levels compared to baseline in both study groups after 12 weeks of concurrent training or the maintenance of daily usual activities (control group). However, after four weeks of detraining, adiponectin levels did not increase in the experimental group despite gradual deconditioning.…”
