Effects of high intensity intermittent training on triglyceride and visceral fat of naval sea service personnel with hypertriglyceridemia

Abstract

Objective To explore the effects of high intensity intermittent training (HIIT) on triglyceride (TG)and visceral fat area (VFA) of naval sea service personnel with hypertriglyceridemia (HTG). Methods Thirty-two male naval personnel were randomly divided into the experimental group (or the HIIT group) and the control group (or the moderate intensity continuous training group) (MICT), each consisting of 16 subjects. The subjects of the 2 groups received health care nutritional education and exercise intervention with different intensity for 4 weeks. Then, differences in TG and VFA before and after intervention were compared between the 2 groups. Results (1) Following intervention, the TG levels of the 2 groups slightly decreased, with that of the HIIT group being (2.36±1.25) mmol/L vs (2.66±1.31) mmol/L and that of the MICT group being (2.03±0.60 vs 2.35±0.66), but without statistical significance(P>0.05). However, there was no statistical significance, when comparisons were made between the 2 groups(P>0.05). (2) After intervention, the VFA levels of the HIIT group decreased significantly [(64.29±15.77) s vs (76.43±17.76) s], (P 0.05). After intervention, statistical differences could be noted, when comparisons were made between the 2 groups(P<0.05). Conclusion As compared with MICT, HIIT could significantly reduce the VFA of naval personnel with HTG, and furthermore, it could improve the TG level, and as a result it could effectively ensure the fighting capability of naval personnel.
