To evaluate the effect of a short-term HIIT program on the selected health-related parameters for overweight/obese young adult women in a university context.
A total of 48 participants were randomly divided into two groups. The exercise group (HIIT) received a HIIT intervention of aerobics for 4 weeks, while the control group (CON) received no training. Body composition including waist circumference (WC), body fat percentage (BF %), Cardiorespiratory fitness (VO2max), the score of Self-Rating Depression Scale (SDS), and Stroop word-color test (SCWT) results were assessed before and after the intervention along with within- and between-group comparisons.
All the indices were significantly improved in HIIT group ( < 0.01) after 4 weeks of intervention. No significant changes were found in CON. There were significant differences between HIIT and CON in cardiovascular fitness ( < 0.01), SDS ( < 0.01) and SCWT ( < 0.05) before and after 4 weeks. In addition, weekly measurements of HIIT effects showed significant changes ( < 0.01) from the second week in the variables of body composition, VO2max, SDS and SCWT when compared with the baseline and maintained the tendency till the end of program.
The short-term HIIT aerobics of the campus program conducted in a non-lab setting induced significant improvements in body composition, cardiovascular fitness, psychological well-being and executive function in overweight young female adults.
评估短期高强度间歇训练（HIIT）计划对大学环境中超重/肥胖年轻成年女性选定的健康相关参数的影响。
总共48名参与者被随机分为两组。运动组（HIIT）接受了为期4周的有氧运动HIIT干预，而对照组（CON）未接受训练。在干预前后评估身体成分，包括腰围（WC）、体脂百分比（BF%）、心肺适能（VO2max）、自评抑郁量表（SDS）得分以及斯特鲁普字色测试（SCWT）结果，并进行组内和组间比较。
干预4周后，HIIT组所有指标均有显著改善（<0.01）。CON组未发现显著变化。4周前后，HIIT组和CON组在心血管适能（<0.01）、SDS（<0.01）和SCWT（<0.05）方面存在显著差异。此外，与基线相比，HIIT效果的每周测量显示，从第二周开始，身体成分、VO2max、SDS和SCWT变量有显著变化（<0.01），并一直保持到计划结束。
在非实验室环境中进行的校园短期HIIT有氧运动计划显著改善了超重年轻女性的身体成分、心血管适能、心理健康和执行功能。
