Effect of High Intensity Intermittent Training and Diet Intervention Management Mode on Body Composition and Cardiopulmonary Function of Obese College Students

Abstract Background Anti-inflammatory cytokines, interleukin-4 (IL-4) and interleukin-13 (IL-13) modulate systemic energy metabolism through modifying body composition parameters. Hence, this study aimed at overweight adolescent boys to explore the effect of high intensity intermittent training (HIIT) on these anti-inflammatory cytokines and body composition parameters. Materials and methods Twenty overweight adolescent boys [aged: 18.0 ± 1.5 years, weight: 81.8 ± 4.3 kg, body mass index (BMI): 27.6 ± 0.8 kg/m2] completed this study. The subjects were randomly assigned into two groups of control (CG, n = 10) and training (TG, n = 10). Subjects in the TG performed their training sessions 3 days/week for 6 weeks. The baseline serum values of IL-4 and IL-13 and anthropometric features were measured 1 day before the beginning of exercise intervention and 1 day after the last training session in a fasting state. Results Six weeks of HIIT significantly increased the baseline serum levels of IL-4 (p = 0.022) and IL-13 (p = 0.014) in overweight adolescent boys. In addition, body weight (BW), BMI and body fat percent (BF%) were reduced in response to HIIT. Moreover, significantly negative correlations were found between changes of IL-4 and IL-13 with changes of BW, BMI and BF%. Conclusions HIIT seems to be an appropriate exercise modality for overweight adolescent boys to induce an anti-inflammatory cytokine response and, to improve body composition.

Background: Research on the effects of high-intensity intermittent training (HIIT) with different volumes on cardiovascular risk factors is limited. Objectives: The current study aimed to determine the effects of eight-week of high-intensity intermittent training and to compare the volumes of training programs on body composition, fitness factors, and cardiovascular risk factors in overweight students. Methods: There were thirty overweight boys (13 - 16years) as the participants of the study who were randomly divided into three groups, including the control group (n = 10), HIIT-1 (n = 10), and MIIT-2 (n = 10). The HIIT-1 group program included 2 × 8 - 15 sets (100 - 110% MAV), and the HIIT-2 group training program included 4 × 4 - 6 sets (100 - 110% MAV). These training programs continued three times a week for eight weeks. Yo-Yo recovery test, RAST test, and ELISA technique were applied to measure aerobic and anaerobic performance, lipid profile, and hematological indices, respectively. Results: The findings showed that except for anaerobic performance and hematological variables in the HIIT-1 group and hematological variables in the HIIT-2 group, other research variables of the two training groups were significantly different from the pre-test (P < 0.05). Besides, in between-group comparison, the findings revealed that there was a significant difference between VO2max, HDL, and TG as well as anaerobic performance between the HIIT-1 and HIIT-2 groups (P < 0.05). Conclusions: The results suggest that HIIT-1 program is suitable to increase aerobic performance and reduce cardiovascular risk factors, while HIIT-2 program may be applied to increase anaerobic performance because the volume of exercises plays a decisive role in possible adaptation resulting from such exercises.
