为进一步了解大学生身体意象和有氧运动的现状，明确问题的成因，探究身体意象对参与有氧运动的影响，本研究有利于改善大学生对自己外貌的认知，以及为大学生参与有氧运动提供指导。

本研究采用文献资料法、问卷调查法和数理统计分析法，向北京师范大学140名本科生发放问卷收集数据，分析了不同性别、年级、专业的大学生身体意象和有氧运动参与的差异性和相关性。研究结果表明：（1）大学生身体意象各维度得分均值为：外表关注（3.39±0.59）＞外表评价（3.17±0.59）＞自觉体重（3.14±0.84）＞身体部位满意度（3.13±0.61）＞肥胖关注（2.73±0.94）＞身体轮廓不满意度（2.14±2.88）；在外表关注、身体部位满意度、肥胖关注方面男女生存在显著差异（P＜0.01）说明女生对自己的外表和肥胖更加关注，且身体部位满意度较低，可能是由于女生更追求苗条体型造成的。（2）大学生运动参与受性别、专业影响较大，男生在运动强度、时间、频率上普遍优于女生，所以女大学生的运动参与情况更应受到关注；文史类专业学生相比于理工类专业学生运动参与较为消极，艺体类专业学生运动参与最积极，可能是由于文史类专业女生较多以及所学专业本身的教育影响。（3）大部分大学生没有达到有氧运动标准，有氧运动参与的频率与身体轮廓不满意度存在显著负相关，即身体轮廓更满意的大学生参加有氧运动更积极。

In order to further understand the current situation of college students' body image and aerobic exercise, to clarify the cause of the problem, and to explore the influence of body image on participation in aerobic exercise, this study is beneficial to improve the college students' perception of their appearance and provide college students with aerobic exercise guide. 

By using the literature method, questionnaire survey method and mathematical statistical analysis method, collecting questionnaires from 140 undergraduates at Beijing Normal University, this study analyzed the differences and correlations of body image and aerobic exercise participation among college students of different genders, grades and majors. The results show that: (1) The average scores of college students' body image in each dimension are: appearance concern (3.39 ± 0.59)＞appearance evaluation (3.17 ± 0.59)＞self perceived weight (3.14 ± 0.84)＞satisfaction of body parts (3.13 ± 0.61)＞Obesity concern (2.73 ± 0.94)＞dissatisfaction of body contour (2.14 ± 2.88); significant differences in male and female survival in appearance concern, body part satisfaction, and obesity concern (P＜0.01) , which indicates that girls are more concerned about their appearance and obesity. The lower satisfaction of body parts may be caused by girls' pursuit of slimmer body shape. (2) College students’ sports participation is greatly affected by gender and specialty. Male college students are generally better than female college students in terms of exercise intensity, time, and frequency. Therefore, female college students' sports participation should be paid more attention to; Compared with students majoring in science and engineering, the participation of students majoring in culture and history is more passive, and the participation of students majoring in the arts and sports is the most active, which probably due to the large number of female students majoring in literature and history, and the educational impact of the majors themselves. (3) Most college students do not meet the standard of aerobic exercise. The frequency of aerobic exercise participation has a significant negative correlation with body contour dissatisfaction, that is, college students with more satisfactory body contour are more active in aerobic exercise.
