To determine the effect of a 12-week high intensity intermittent exercise (HIIE) intervention on total body, abdominal, trunk, visceral fat mass, and fat free mass of young overweight males. Participants were randomly assigned to either exercise or control group. The intervention group received HIIE three times per week, 20 min per session, for 12 weeks. Aerobic power improved significantly (P < 0.001) by 15% for the exercising group. Exercisers compared to controls experienced significant weight loss of 1.5 kg (P < 0.005) and a significant reduction in total fat mass of 2 kg (P < 0.001). Abdominal and trunk adiposity was also significantly reduced in the exercising group by 0.1 kg (P < 0.05) and 1.5 kg (P < 0.001). Also the exercise group had a significant (P < 0.01) 17% reduction in visceral fat after 12 weeks of HIIE, whereas waist circumference was significantly decreased by week six (P < 0.001). Fat free mass was significantly increased (P < 0.05) in the exercising group by 0.4 kg for the leg and 0.7 kg for the trunk. No significant change (P > 0.05) occurred in levels of insulin, HOMA-IR, and blood lipids. Twelve weeks of HIIE resulted in significant reductions in total, abdominal, trunk, and visceral fat and significant increases in fat free mass and aerobic power.
为了确定为期12周的高强度间歇运动（HIIE）干预对年轻超重男性的全身、腹部、躯干、内脏脂肪量以及去脂体重的影响。参与者被随机分配到运动组或对照组。干预组每周进行3次HIIE，每次20分钟，共12周。运动组的有氧能力显著提高（P < 0.001），提高了15%。与对照组相比，运动者体重显著减轻了1.5千克（P < 0.005），总脂肪量显著减少了2千克（P < 0.001）。运动组的腹部和躯干脂肪也分别显著减少了0.1千克（P < 0.05）和1.5千克（P < 0.001）。此外，运动组在进行12周的HIIE后内脏脂肪显著减少（P < 0.01），减少了17%，而腰围在第6周时显著减小（P < 0.001）。运动组的腿部去脂体重显著增加（P < 0.05），增加了0.4千克，躯干去脂体重增加了0.7千克。胰岛素、HOMA-IR和血脂水平未发生显著变化（P > 0.05）。12周的HIIE导致全身、腹部、躯干和内脏脂肪显著减少，去脂体重和有氧能力显著增加。
