为了对广州市成年人体质中存在的四个主要问题的产生原因进行深入分析，以改善广大市民体质状况。通过问卷调查法，对已有的九个理论假设原因进行了调查论证和实证检验。结果表明：广州市成年人体重偏轻属正常范围之内，他们没有盲目减肥；心肺功能较差主要是市民不健康的生活方式以及缺乏体育锻炼和体育锻炼不科学所致，与环境污染有一定联系；商业服务人员体质较差的客观原因是工作时间长而无规律，主观原因是取向于钱的价值观；经常到消费性体育场所进行锻炼人群的体质优良率较低，是因为他们的体育动机和体育价值观趋向于非健身性以及缺乏科学的健身指导。
In order to analyze the causes of the four major problems existing in adults in Guangzhou City, we should improve the physical condition of the general public. Through the questionnaire survey, the existing nine theoretical hypotheses were investigated and empirically tested. The results showed that adults in Guangzhou were within the normal range of body weight, and they did not lose weight blindly. Poor cardiopulmonary function was mainly caused by the unhealthy lifestyle of citizens and unscientific lack of physical exercise and physical exercise, and had some connection with environmental pollution The objective reason for the poor physical condition of business service personnel is the long and erratic working hours, the subjective reasons are the values oriented toward money, and the low rate of physical fitness often performed by the consuming sports venues because of their sports motivation and Sports values tend to be non-fitness and lack of scientific fitness guidance.
