摘要

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—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低于标准值, 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低于标准值(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。

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 of female college students with abdominal obesity was significantly lower than that of the control group, all the differences were statistically significant (t=2.48, 2.61, P < 0.05). Fat_max of female college students with obesity under the scapula was significantly lower than that of the control group (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.
