Objective This study compared high-intensity interval training with crossover point training to provide more effective exercise guidance for overweight female university students to maintain or improve blood lipid health.
Methods A total of 27 overweight female university students were enrolled in the study (20.93±2.23 years) and randomly divided into a crossover point training group (COP group), high-intensity interval training group (HIIT group) and control group. The COP group and HIIT group took part in an exercise training program three times a week for 10 weeks. The COP group completed 45 min of COP continuous exercise intensity training each time. The HIIT group completed five groups of HIIT each time. The control group kept normal physical activity status.
Results After 10 weeks of COP continuous intensity exercise training or HIIT exercise training, the morphological indicators of the COP group were significantly improved, with a significant decrease in BMI (−0.85 kg/m 2), a very significant decrease in waist circumference (−2.94 cm) and a significant decrease in hip circumference and body fat percentage (−2.23 cm, −1.19%, P<0.05). A significant decrease was observed in both serum apolipoprotein B (Apo B) levels (−9.79 mg/dL) and the ApoB/ApoAI ratio (−0.19). Moreover, the change in ApoB/ApoAI of the COP group after the exercise program was significantly greater than that of the HIIT group (−0.19, 0.07, P<0.05).
Conclusion After 10 weeks of taking part in the exercise program, it was found that compared with HIIT, COP continuous intensity exercise training is more effective in improving abdominal obesity, lipid health and cardiovascular risk factors.
【摘要】 目的 比较高强度间歇训练与交叉点运动训练对身体的影响, 为超重女大学生维持或改善血脂健康提供更有效 的运动指导。 方法 研究选取北京高校 27 名超重女大学生, 平均年龄 (20.93±2.23) 岁。随机分为交叉点运动训练组 (COP 组) (10 人)、高强度间歇训练组 (HIIT 组) (10 人) 和对照组 (7 人)。COP 组和 HIIT 组进行 10 周每周 3 次的运动干 预, COP 组每次完成 45 min COP 强度持续运动, HIIT 组每次完成 5 组 HIIT; 对照组保持平时的体力活动状态不变。 结果 在 10 周的 COP 强度持续运动或 HIIT 干预后, COP 组的形态学指标显著改善, 体质量指数 (BMI) (−0.85 kg/m 2)、腰围 (−2.94 cm)、臀围和体脂率 (−2.23 cm, −1.19%) 均下降;血脂代谢指标及相关比值指标显著改善, 血清载脂蛋白 B (ApoB) 水平 (−9.79 mg/dL)、ApoB/载脂蛋白 AI (ApoAI) (−0.19) 均下降, 且 COP 组干预前后 ApoB/ApoAI 的变化量高于 HIIT 组 (−0.19, 0.07) ( P 值均<0.05)。 结论 经过 10 周的运动干预, COP 强度持续运动与 HIIT 相比是更有效的改善腹部肥胖、血脂健康、心血管危险因素的运动方式。
