Structured exercise can improve body image among women. Less is known if these associations extend to lifestyle physical activity-all activities of daily living with a full range of intensity. The purpose of this cross-sectional study was to examine the relationships between lifestyle physical activity and body image in undergraduate women (n = 120; 18-23 years) during the spring of 2010 and 2011. One week of lifestyle physical activity was measured objectively (accelerometer) and subjectively (7-Day Physical Activity Recall Questionnaire). Attitudinal dimensions of body image were assessed using the Multidimensional Body-Self Relations Questionnaire. Physical activity was unrelated to appearance-related dimensions of women's body image. Objectively-measured vigorous physical activity was positively related to investment in fitness and health (p < .005), while moderate physical activity was related to investment in fitness (p < .005). Light physical activity was unrelated to women's body image. A greater amount of self-reported vigorous physical activity was related to greater investment in fitness (p < .005). Results suggested that unlike structured exercise, lifestyle physical activity was generally unrelated to women's body image. The act of exercising may be more important than accumulation of lifestyle physical activity when considering women's body image.
有组织的锻炼可以改善女性的身体意象。对于这些关联是否延伸到生活方式体力活动（即各种强度的所有日常生活活动），我们了解得较少。这项横断面研究的目的是在2010年和2011年春季，调查本科女生（n = 120；18 - 23岁）的生活方式体力活动与身体意象之间的关系。通过客观测量（加速度计）和主观测量（7天体力活动回忆问卷）对一周的生活方式体力活动进行评估。使用多维身体自我关系问卷评估身体意象的态度维度。体力活动与女性身体意象的外貌相关维度无关。客观测量的剧烈体力活动与对健康和健身的投入呈正相关（p < 0.005），而中等强度体力活动与对健身的投入相关（p < 0.005）。轻度体力活动与女性身体意象无关。自我报告的较多剧烈体力活动与对健身的更多投入相关（p < 0.005）。结果表明，与有组织的锻炼不同，生活方式体力活动通常与女性身体意象无关。在考虑女性身体意象时，锻炼行为可能比生活方式体力活动的积累更重要。
