To conduct a meta-analysis to explore the optimal dosage of Tai chi exercise that positively influences the sleep quality of the older people.
A literature search was conducted from 2004 to October 2024 in PubMed, Embase, Web of Science, Google Scholar, Cochrane Library, and Chinese databases (CNKI and Wanfang) for randomised controlled trials in Chinese and English on Tai chi improving sleep quality in the older people. Data extraction and verification were performed by two independent researchers. Additionally, a meta-analysis of the mean difference (MD) and 95% confidence interval (CI) was conducted using RevMan 5.4.
A total of nine randomised controlled trials involving 1,166 older participants were included. Compared with the control group, Tai chi significantly reduced the total Pittsburgh Sleep Quality Index (PSQI) scores in the older people [MD = - 1.53, 95% CI (- 2.18, - 0.89), p < 0.001], with heterogeneity results Q = 53.63, df = 12, and I of 78% (p < 0.001); Total weekly duration of Tai chi exercise: Less than 150 min reduced PSQI scores, but the difference was not statistically significant [MD = - 1.47, 95% CI (- 3.89, 0.95), p = 0.23]. Between 150-300 min significantly reduced PSQI scores [MD = - 1.54, 95% CI (- 2.00, - 1.08), p < 0.001]; Duration of Tai chi exercise programme: 8-12 weeks significantly reduced PSQI scores [MD = - 1.93, 95% CI (- 2.60, - 1.25), p < 0.001]; 16-24 weeks significantly reduced PSQI scores [MD = - 1.27, 95% CI (- 2.27, - 0.26), p = 0.01]; Single session duration of Tai chi exercise: 60 min significantly reduced PSQI scores [MD = - 2.17, 95% CI (- 3.15, - 1.18), p < 0.001]; Less than 60 min (25-45 min) significantly reduced PSQI scores [MD = - 0.92, 95% CI (- 1.63, - 0.20), p = 0.01].
Older individuals engaging in at least 150 min per week of Tai chi practice can improve sleep quality. Beyond this threshold, extending the duration of individual practice sessions or the exercise programme does not yield additional benefits for sleep quality.
进行一项荟萃分析，以探索能对老年人睡眠质量产生积极影响的太极拳运动的最佳剂量。
于2004年至2024年10月在PubMed、Embase、Web of Science、谷歌学术、Cochrane图书馆以及中文数据库（知网和万方）中进行文献检索，查找关于太极拳改善老年人睡眠质量的中英文随机对照试验。由两名独立研究人员进行数据提取和验证。此外，使用RevMan 5.4对平均差（MD）和95%置信区间（CI）进行荟萃分析。
共纳入9项随机对照试验，涉及1166名老年参与者。与对照组相比，太极拳显著降低了老年人的匹兹堡睡眠质量指数（PSQI）总分[MD = -1.53，95%CI（-2.18，-0.89），p < 0.001]，异质性结果Q = 53.63，df =
12，I²为78%（p < 0.001）；太极拳每周总运动时长：少于150分钟可降低PSQI总分，但差异无统计学意义[MD = -1.47，95%CI（-3.89，0.9
5），p = 0.23]。150 - 300分钟可显著降低PSQI总分[MD = -1.54，95%CI（-2.00，-1.08），p < 0.001]；太极拳运动计划时长：8 -
12周可显著降低PSQI总分[MD = -1.93，95%CI（-2.60，-1.25），p < 0.001]；16 - 24周可显著降低PSQI总分[MD = -1.27，95%CI（-2.27，-0.26），p = 0.01]；单次太极拳运动时长：60分钟可显著降低PSQI总分[MD = -2.17，95%CI（-3.15，-1.18），p < 0.001]；少于60分钟（25 - 45分钟）可显著降低PSQI总分[MD = -0.92，95%CI（-1.63，-0.20），p = 0.01]。
每周至少进行150分钟太极拳练习的老年人可改善睡眠质量。超过此阈值后，延长单次练习时长或运动计划时长对睡眠质量并无额外益处。
