Sedentary lifestyle combined with smoking, contributes to the development of a set of chronic diseases and to accelerating the course of aging. The aim of the study was to compare the hemodynamic and nutritional parameters between elderly persons practicing regular physical activity, nonsmokers and ex-smokers.
The sample was comprised of 40 elderly people practicing regular physical activity for 12 months, divided into a Nonsmoker Group and an Ex-smoker Group. During a year four trimestrial evaluations were performed, in which the hemodynamic (blood pressure, heart rate- HR and VO2) and nutritional status (measured by body mass index) data were collected. The paired t-test and t-test for independent samples were applied in the intragroup and intergroup analysis, respectively.
The mean age of the groups was 68.35 years, with the majority of individuals in the Nonsmoker Group being women (n = 15) and the Ex-smoker Group composed of men (n = 11). In both groups the variables studied were within the limits of normality for the age. HR was diminished in the Nonsmoker Group in comparison with the Ex-smoker Group (p = 0.045) between the first and last evaluation. In the intragroup analysis it was verified that after one year of exercise, there was significant reduction in the HR in the Nonsmoker Group (p = 0.002) and a significant increase in VO2 for the Ex-smoker Group (p = 0.010). There are no significant differences between the hemodynamic and nutritional conditions in both groups.
In elderly persons practicing regular physical activity, it was observed that the studied variables were maintained over the course of a year, and there was no association with the history of smoking, except for HR and VO2.
久坐的生活方式加上吸烟，会导致一系列慢性疾病的发生，并加速衰老过程。本研究旨在比较定期进行身体活动、不吸烟和曾经吸烟的老年人之间的血液动力学和营养参数。
该样本由 40 名定期进行 12 个月身体活动的老年人组成，分为不吸烟者组和曾经吸烟者组。在一年内进行了四次季度评估，收集了血液动力学（血压、心率- HR 和 VO2）和营养状况（通过体重指数测量）数据。分别应用配对 t 检验和独立样本 t 检验进行组内和组间分析。
两组的平均年龄均为 68.35 岁，不吸烟者组中大多数为女性（n = 15），曾经吸烟者组中大多数为男性（n = 11）。在两组中，所研究的变量均在年龄的正常值范围内。与曾经吸烟者组相比，不吸烟者组的 HR 在第一次和最后一次评估时均降低（p = 0.045）。组内分析显示，经过一年的运动后，不吸烟者组的 HR 显著降低（p = 0.002），而曾经吸烟者组的 VO2 显著增加（p = 0.010）。两组之间的血液动力学和营养状况没有显著差异。
在定期进行身体活动的老年人中，观察到研究变量在一年内保持不变，与吸烟史无关，除了 HR 和 VO2。
