          Abstract

          Objective To explore the relationship between the adiposity index and the maximum fat oxidation intensity (Fat max) of obese female college students, and to provide a composite indicas for formulating exercise prescriptions.

          Methods Fifty-four obese female college students without sports background in Chongqing from June 2017 to March 2018 were selected as subjects. Fat max was measured through an incremental load exercise test on a sports treadmill in all participants. Differences of fat max among pariticipants with different body fat percentage (BFP), waist-to-hip ratio (WHR), and skinfold thickness of different parts (abdomen, lower scapula, upper arm and humerus) were compared. Associations between different body fat percentage (BFP), waist-to-hip ratio (WHR), skinfold thickness of different parts (abdomen, lower scapula, upper arm triceps) and Fat max were analyzed.

          Results Fat max (MET, %VO 2max) of female college students classified as obese by BFP, WHR, abdominal, upper arm triceps, and lower scapula indicators were lower than the control group. Fat max [(6.19±1.21) MET, (48.71±8.62) % VO 2max] of female college students with abdominal obesity was significantly lower than that of the control group [(7.65±0.88) MET, (57.64±8.90) % VO 2max], all the differences were statistically significant ( t = 2.48, 2.61, P<0.05). Fat max [(6.10±1.16) MET] of female college students with obesity under the scapula was significantly lower than that of the control group [(7.18±1.25) MET] ( t = 2.50, P<0.05), and negative correlation was found ( r = −0.27, P<0.01).

          Conclusion The obesity indicas are closely related to Fat max among obese female college students, and the skinfold thickness of the abdominal and back show prominent impact on the Fat max of obese female college students.

          Abstract

          【摘要】 目的 探讨肥胖女大学生肥胖指标与最大脂肪氧化强度 (Fat max) 的关系, 为制定运动处方时提供多面考量指标。 方法 2017 年 6 月 一2018 年 3 月在西南大学通过招募的方式选取 54 例无运动背景的肥胖女大学生作为受试者。所有受 试者通过运动跑台的递增负荷运动试验测定 Fat max, 比较肥胖女大学生不同体脂百分比 (BFP)、腰臀比 (WHR) 及不同部位 皮褶厚度(腹部、肩胛骨下部、上臂肱三头肌)对应的 Fat max 差异, 不同体脂百分比 (BFP)、腰臀比 (WHR) 及不同部位皮褶厚 度 (腹部、肩胛骨下部、上臂肱三头肌) 与 Fat max 关系。 结果 由 BFP、WHR、腹部、上臂肱三头肌及肩胛骨下部指标判定为 肥胖的女大学生 Fat max (MET, %VO 2max) 均低于标准值。其中腹部肥胖女大学生 Fat max [(6.19±1.21)MET, (48.71±8.62)% VO 2max] 低于标准值 [(7.65±0.88)MET, (57.64±8.90)%VO 2max], 差异均有统计学意义 ( t 值分别为 2.48,2.61, P 值均<0.05); 肩胛骨下部肥胖女大学生 Fat max (6.10±1.16)MET] 低于标准值 [(7.18±1.25)MET] ( t = 2.50, P<0.05), 且两者呈负 相关 ( r = −0.27, P<0.01)。 结论 肥胖女大学生的肥胖指标均与 Fat max 关系密切, 其中腹部、背部皮褶厚度对肥胖女大学生 Fat max 的影响更为突出。
