We compared the health benefits of two different Tai Chi interventions tailored for improving blood pressure (BP) (PRESSURE) or balance (BALANCE).
randomized controlled trial.
Community dwelling older adults (≥60yr) practiced Tai Chi at the fitness center of a continuous care community.
We tailored PRESSURE to emphasize breathing techniques and mental relaxation and BALANCE to emphasize movement principles that challenged balance. Subjects were randomized to PRESSURE (n = 12), BALANCE (n = 13), or CONTROL (n = 10). Tai Chi was practiced 3 sessions/wk, 60 min/session for 12 wk. CONTROL performed normal daily activities.
We compared the change in cardiometabolic health, balance, and functional fitness between groups with ANCOVA using baseline values, age, and body mass index as covariates.
Subjects were physically active, Tai Chi naive (97.1 %), white, mostly female (82.9 %), and older (78.9 ± 5.7 yr) with resting systolic BP (SBP) of 126.5 ± 14.4 mmHg and diastolic BP of 69.3 ± 8.4 mmHg. PRESSURE significantly improved Chair Sit-to-Stand Test (CSTS) (1.0 ± 1.8 vs.-0.6 ± 0.8times/30s,p = 0.03) versus CONTROL, and gait speed (12.8±43.3 vs.-24.1±22.4cm/sec, p = 0.02) versus BALANCE. Meanwhile, BALANCE significantly improved Single Leg Stance Test (5.4±18.0 vs.-8.2±10.3 s, p = 0.049) and CSTS (1.0±1.7 vs.-0.6±0.8times/30s, p = 0.03), and tended to lower SBP (-4.2±16.0 vs. 3.5±8.3mmHg, p = 0.052) versus CONTROL.
Within 3 months, Tai Chi improved several health outcomes independent of the type of practice among physically active, Tai Chi naive older adults. Therefore, healthcare and exercise professionals may recommend Tai Chi to physically active older adults without specifying the type of practice.
我们比较了两种不同的太极拳干预措施对改善血压（BP）（PRESSURE）或平衡（BALANCE）的健康益处。
随机对照试验。
社区居住的老年人（≥60 岁）在持续护理社区的健身中心练习太极拳。
我们为 PRESSURE 量身定制，强调呼吸技巧和心理放松，为 BALANCE 量身定制，强调挑战平衡的运动原则。将受试者随机分为 PRESSURE（n = 12）、BALANCE（n = 13）或 CONTROL（n = 10）组。CONTROL 组进行正常的日常活动。Tai Chi 每周练习 3 次，每次 60 分钟。
我们使用基线值、年龄和体重指数作为协变量，通过协方差分析（ANCOVA）比较各组之间的心脏代谢健康、平衡和功能健身的变化。
受试者身体活跃，对太极拳一无所知（97.1%），为白人，大多数为女性（82.9%），年龄较大（78.9±5.7 岁），静息收缩压（SBP）为 126.5±14.4mmHg，舒张压为 69.3±8.4mmHg。与 CONTROL 组相比，PRESSURE 显著改善了坐站测试（CSTS）（1.0±1.8 次/30s 与 0.6±0.8 次/30s，p=0.03），与 BALANCE 组相比，步态速度（12.8±43.3cm/s 与 24.1±22.4cm/s）也显著改善。与此同时，BALANCE 显著改善了单腿站立测试（5.4±18.0s 与 8.2±10.3s，p=0.049）和 CSTS（1.0±1.7 次/30s 与 0.6±0.8 次/30s，p=0.03），并且倾向于降低 SBP（-4.2±16.0mmHg 与 3.5±8.3mmHg，p=0.052）与 CONTROL 相比。
在 3 个月内，太极拳改善了身体健康结果，而与练习类型无关，在身体活跃、对太极拳一无所知的老年人中。因此，医疗保健和运动专业人员可能会向身体活跃的老年人推荐太极拳，而无需指定练习类型。
