Safe and gentle exercise may be important for older adults overcoming a sedentary lifestyle. Sign Chi Do (SCD), a novel form of low impact exercise, has shown improved balance and endurance in healthy older adults, and there have been no SCD-related injuries reported. Sedentary older adults are known to have a greater cardiovascular (CV) response to physical activity than those who regularly exercise. However their CV response to SCD is unknown. This study explored the acute CV response of older adults to SCD. Cross-sectional study of 34 sedentary and moderately active adults over age 55 with no previous experience practicing SCD. Participants completed a 10 min session of SCD. CV outcomes of heart rate, blood pressure, rate pressure product were recorded at 0, 5, 10 min of SCD performance, and after 10 min of rest. HR was recorded every minute. There was no difference in CV scores of sedentary and moderately active older adults after a session of SCD-related activity. All CV scores increased at 5 min, were maintained at 10 min, and returned to baseline within 10 min post SCD (p < 0.05). SCD may be a safe way to increase participation in regular exercise by sedentary older adults.
安全温和的运动对于克服久坐不动生活方式的老年人可能很重要。Sign Chi Do（SCD）是一种新型的低强度运动形式，已显示出能改善健康老年人的平衡能力和耐力，且未报告与SCD相关的损伤。众所周知，久坐不动的老年人对体育活动的心血管（CV）反应比经常锻炼的人更大。然而，他们对SCD的CV反应尚不清楚。本研究探讨了老年人对SCD的急性CV反应。对34名55岁以上、以前没有练习SCD经验的久坐不动和中度活跃的成年人进行横断面研究。参与者完成了10分钟的SCD课程。在SCD表现的0、5、10分钟以及休息10分钟后记录心率、血压、心率血压乘积等CV指标。每分钟记录心率。在进行了一次与SCD相关的活动后，久坐不动和中度活跃的老年人的CV评分没有差异。所有CV评分在5分钟时升高，在10分钟时保持不变，并在SCD后10分钟内恢复到基线水平（p<0.05）。SCD可能是一种让久坐不动的老年人增加参与定期锻炼的安全方式。
