Arterial stiffness is associated with an array of debilitating health conditions. While exercise typically has beneficial effects on both arterial stiffness and overall health, more research is needed to understand the associations of different types of fitness indices with arterial stiffness. To investigate the relationship between balance, strength, cardiovascular fitness and physical activity with arterial stiffness (as measured by pulse wave velocity (PWV)) in older adults. Eighty retirement-village residents (24 males, 56 females, age: 78.2 ± 6.4 years, weight: 69.4 ± 12.5 kg, height: 162.9 ± 8.5 cm) completed the Yale Physical Activity Survey, PWV measurement, 30-s sit-to-stand leg strength test, hand grip strength assessment, 4-stage balance test, and a 6-min walk fitness test. The number of exiting risk factors (smoking, previous heart incidents, previous stroke(s), having hypertension, or taking anti-hypertension medication) were tallied. Pearson's correlations were used to assess the relationship between PWV and health and fitness parameters. Results were interpreted using qualitative inference. The number of risk factors (r = 0.57, < 0.001), age (r = 0.51, < 0.001) and systolic blood pressure (r = 0.50, = 0.001) had strong, harmful associations with PWV. Total physical activity minutes/week (r = -0.31 = 0.01), total energy expenditure Kcal/week (r = -0.30, = 0.01), and the 6-min walk test (r = -0.29, = 0.01) had a moderate, beneficial association with PWV, while sit-to-stand (r = -0.27, = 0.02) and balance (r = -0.27, = 0.01) had a weak, beneficial association with PWV. Hand grip strength (r = 0.02, = 0.94) and body mass index (r = -0.04, = 0.75) had no significant associations with PWV. All measured fitness indices had beneficial associations with PWV. However, having more risk factors, increased age, and higher systolic blood pressure had significant (harmful) associations with PWV in our older population. Controlling cardiovascular risk factors, especially high systolic blood pressure, is likely to have the largest beneficial effect on PWV. Improving general physical activity, including walking capacity, may prove beneficial in improving PWV in an older population.
动脉僵硬度与一系列使人衰弱的健康状况相关。虽然运动通常对动脉僵硬度和整体健康都有有益影响,但仍需要更多研究来了解不同类型的健康指标与动脉僵硬度之间的关联。为了调查老年人的平衡能力、力量、心血管健康状况和身体活动与动脉僵硬度(通过脉搏波速度(PWV)测量)之间的关系。80名退休村居民(24名男性,56名女性,年龄:78.2±6.4岁,体重:69.4±12.5千克,身高:162.9±8.5厘米)完成了耶鲁身体活动调查、PWV测量、30秒坐立腿部力量测试、握力评估、4阶段平衡测试和6分钟步行健康测试。统计了现存风险因素(吸烟、既往心脏病发作、既往中风、患有高血压或服用抗高血压药物)的数量。使用Pearson相关性分析来评估PWV与健康和健身参数之间的关系。结果采用定性推断进行解释。风险因素数量(r = 0.57,<0.001)、年龄(r = 0.51,<0.001)和收缩压(r = 0.50,= 0.001)与PWV有强烈的有害关联。每周总身体活动分钟数(r = -0.31,= 0.01)、每周总能量消耗千卡数(r = -0.30,= 0.01)和6分钟步行测试(r = -0.29,= 0.01)与PWV有中度有益关联,而坐立测试(r = -0.27,= 0.02)和平衡测试(r = -0.27,= 0.01)与PWV有微弱有益关联。握力(r = 0.02,= 0.94)和体重指数(r = -0.04,= 0.75)与PWV无显著关联。所有测量的健康指标与PWV都有有益关联。然而,在我们的老年人群中,存在更多风险因素、年龄增加和收缩压升高与PWV有显著(有害)关联。控制心血管风险因素,尤其是高收缩压,可能对PWV有最大的有益影响。改善一般身体活动,包括步行能力,可能对改善老年人群的PWV有益。
