A community survey examined attitudes to exercise in relation to health, measured levels of exercise participation, and related exercise participation to resting pulse rate. A questionnaire was sent to 400 Southampton residents selected by a systematic random sample from the electoral roll, and provided 259 useful responses, yielding an effective response rate of 68%, with an average age of 46 years. Attitudes to health benefits of exercise were generally very positive; 92% thought that exercise was important for staying in good health. Attitudes were less positive in subjects over 50 years old, and in social classes IV and V. Although 35% had done some vigorous exercise during the last four weeks only 7% of social classes IV and V had done so. A total of 22 (8.5%) had exercised for at least 20 minutes, 3 or more times per week, and 17 (77%) of these were males with an average age of 29 years. Ninety per cent of the sample were able to take their own resting heart rate. Resting heart rate was 7 beat.min-1 lower in subjects who exercised for at least 20 minutes 3 or more times per week than the average.
一项社区调查研究了人们对运动与健康关系的态度，测量了运动参与水平，并将运动参与情况与静息心率进行了关联分析。通过系统随机抽样从选民名单中选取了400名南安普敦居民，并向他们发放了问卷，共收到259份有效回复，有效回复率为68%，平均年龄为46岁。人们对运动对健康益处的态度总体上非常积极；92%的人认为运动对保持健康很重要。50岁以上的人群以及社会阶层IV和V的人群态度则没那么积极。尽管35%的人在过去四周内进行了一些剧烈运动，但社会阶层IV和V中只有7%的人进行了剧烈运动。共有22人（8.5%）每周至少运动20分钟，且每周运动3次或更多次，其中17人（77%）为男性，平均年龄为29岁。90%的样本能够自行测量静息心率。每周至少运动20分钟、运动3次或更多次的受试者的静息心率比平均水平低7次·分钟⁻¹。
