PHYSICAL ACTIVITY OF OLDER MEXICAN AMERICAN WOMEN

这个KO1的长期目标是扩大调查员的 研究增加少数民族的体育活动和锻炼 老年人，从而促进更大的健康和自主性。公元2000年 目标(1991)设定了增加体力活动的目标和 卫生局局长关于活动和健康的报告(1996)记录了 老年少数族裔妇女的体力活动缺乏改善。 申请人的社区卫生背景和研究已经在 活动和健康行为的心理社会方面的领域。这 KO1将通过四个具体目标帮助她扩大研究。 目标1是提高她在运动生理学和运动技能方面的知识和技能 墨西哥裔美国人通过课程学习和咨询 这些领域的专家。目标2是进行一项先导研究，以衡量 血压(BP)、静息脉搏(RP)、体重指数(BMI)、 20岁以上老年人的感觉疲劳(RPE)、最大摄氧量(V02max)和估计摄氧量(V02max) 墨西哥裔美国女性经常锻炼以确定 V02max估计值作为有氧运动指标的可行性 能力(研究1)。目标3是检查促进或抑制的因素 老年墨西哥裔美国妇女的锻炼(研究2)。目标4是发展 并测试一项干预措施，以帮助久坐不动的墨西哥裔美国妇女 65岁及以上的人采用并维持步行计划(研究2)。这个 干预措施将包括12周的监督步行和 与运动相关的教学，随后进行9个月的跟踪调查 加强步行训练。坚持性和知识将得到衡量， 生理(BMI、BP、RP、V02max估计)和心理社会 (功能健康、决策平衡、自我效能、习惯性身体 活动)结果变量将在12周后进行测量 监督步行，9个月后。定性数据将是 在活动日志和个人数据调查问卷中收集以跟踪 女性对干预的反应、兴趣、障碍和 锻炼的促进者。研究2为重复测量实验 设计对象为65名久坐不动的墨西哥裔美国女性和65名对照受试者。 联合发起人将监督、指导和评估研究人员 这些研究。

The long-term objective of this KO1 is to expand the investigator's research to increase physical activity and exercise among minority elderly, thereby promoting greater health and autonomy. The Year 2000 Objectives (1991) set goals for increasing physical activity and the Surgeon General's Report on Activity and Health (1996) documents the lack of improvement in physical activity among older minority women. The applicant's community health background and research have been in the areas of psychosocial aspects of activity and health behavior. This KO1 will assist her to expand her research through four specific aims. Aim 1 is to enhance her knowledge and skills in exercise physiology and Mexican-American culture through course work and consultation with experts in these areas. Aim 2 is to conduct a pilot study to measure blood pressure (BP), resting pulse (RP), body mass index (BMI), rate of perceived exertion (RPE), V02max and estimated V02max in 20 older Mexican American women who exercise regularly to determine the feasibility of using estimated V02max as an indicator of aerobic capacity (Study 1). Aim 3 is to examine factors that promote or inhibit exercise in older Mexican-American women (Study 2). Aim 4 is to develop and test an intervention to assist sedentary Mexican-American women aged 65 and older to adopt and maintain a walking program (Study 2). The intervention will consist of 12 weeks of supervised walking with exercise-related teaching, followed by 9 months of follow-up to reinforce the walking. Adherence and knowledge will be measured and the physiological (BMI, BP, RP, V02max estimate) and psychosocial (functional health, decisional balance, self-efficacy, habitual physical activity) outcome variables will be measured after 12 weeks of supervised walking, and 9 months later. Qualitative data will be collected in an activity log and personal data questionnaire to track the women's reaction to the intervention, interests, barriers and facilitators to exercise. Study 2 is a repeated measures experimental design with 65 sedentary Mexican-American women and 65 control subjects. The co-sponsors will supervise, guide, and evaluate the researcher in the studies.
