Excess abdominal adiposity has been associated with increased morbidity and mortality. Though aerobic exercises significantly reduce general adiposity, it has no effect on abdominal adiposity. However the effects of a combination of aerobic and abdominal strengthening exercises on abdominal adiposity are not known.
This study was designed to evaluate the effects of a 12-week aerobic and abdominal strengthening exercise programme on abdominal adiposity in sedentary adults.
A total of 105 consenting sedentary adults participated in this study. They were randomly recruited from the Ibadan metropolis. Participants went through exercise training which included aerobic and abdominal strengthening exercises. Exercise was carried out thrice weekly for 12 consecutive weeks. Abdominal adiposity indices of Waist Circumference (WC), Waist-to-Hip Ratio (WHR), Sum of Abdominal Skinfold (SAS) were measured at baseline, 4th, 8th and 12th weeks. Data were analyzed using descriptive statistics of mean and standard deviation and repeated measures ANOVA at p = 0.05.
74 participants with mean age (34.8 +/- 9.1 yrs) completed the study. At the end of the 12 -week exercise, there was significant reduction in WC (94.8 +/- 10.2 to 89.2 +/- 9.8 cm), WHR (0.89 0.06 to 0.86 +/- 0.05) and SAS (88.9 +/- 10.9 to 77.3+/- 13.5 mm) among the female participants. Within the male participants, there was significant reduction in WC (88.5 +/- 7.4 to 83.8 +/- 4.7 cm), and in SAS (60.1 +/- 8.4 to 54.5 +/- 8.5 mm), but no statistically significant difference was observed in the WHR (0.88 +/- 0.04 to 0.87 +/- 0.06).
Twelve-week aerobic and abdominal strengthening exercise programme, without caloric restriction, reduced abdominal adiposity in apparently-healthy sedentary adults, hence it is recommended for its beneficial effects on abdominal adiposity.
腹部脂肪过多与发病率和死亡率增加相关。尽管有氧运动能显著降低总体脂肪量，但对腹部脂肪并无影响。然而，有氧运动与腹部强化运动相结合对腹部脂肪的影响尚不清楚。
本研究旨在评估一项为期12周的有氧运动和腹部强化运动计划对久坐不动的成年人腹部脂肪的影响。
共有105名自愿参与的久坐不动的成年人参与了本研究。他们是从伊巴丹市随机招募的。参与者接受了包括有氧运动和腹部强化运动在内的运动训练。运动每周进行三次，连续进行12周。在基线、第4周、第8周和第12周测量腹部脂肪指标，包括腰围（WC）、腰臀比（WHR）、腹部皮褶厚度总和（SAS）。使用均值和标准差的描述性统计以及p = 0.05时的重复测量方差分析对数据进行分析。
74名平均年龄为（34.8±9.1岁）的参与者完成了研究。在为期12周的运动结束时，女性参与者的腰围（从94.8±10.2厘米降至89.2±9.8厘米）、腰臀比（从0.89±0.06降至0.86±0.05）和腹部皮褶厚度总和（从88.9±10.9毫米降至77.3±13.5毫米）均有显著降低。在男性参与者中，腰围（从88.5±7.4厘米降至83.8±4.7厘米）和腹部皮褶厚度总和（从60.1±8.4毫米降至54.5±8.5毫米）有显著降低，但腰臀比（从0.88±0.04降至0.87±0.06）未观察到统计学上的显著差异。
为期12周的有氧运动和腹部强化运动计划，在不限制热量摄入的情况下，降低了明显健康的久坐不动成年人的腹部脂肪，因此因其对腹部脂肪的有益影响而被推荐。
