Inspiratory muscle training (IMT) improved balance ability and respiratory muscle function in healthy older adults. The current study is a retrospective analysis to explore the relationship between inspiratory muscle function, balance ability, and adaptation to IMT. All participants (total = 129; IMT = 60; age range = 65-85 years) performed inspiratory and balance assessments, including the mini-balance evaluation system test, maximal inspiratory pressure, and peak inspiratory flow tests. Baseline inspiratory muscle function was positively related to balance ability (p < .05), and IMT-induced improvements in inspiratory function (23.3% in maximal inspiratory pressure, 8.0% in peak inspiratory flow rate, 14.9% in maximal peak inspiratory power) were related to improvements in balance (10.6% in mini-balance evaluation system test), with the greatest improvements (17.0%) observed in the oldest participants (76-85 years old, p < .05). In conclusion, with or without IMT, positive associations between inspiratory function and balance ability exist, with greater improvements in inspiratory muscle function related to greater improvements in balance ability.
吸气肌训练（IMT）可改善健康老年人的平衡能力和呼吸肌功能。本研究为回顾性分析，旨在探讨吸气肌功能、平衡能力与IMT适应性之间的关系。所有参与者（共129人；IMT组60人；年龄范围65 - 85岁）进行了吸气和平衡评估，包括迷你平衡评估系统测试、最大吸气压力和吸气峰值流量测试。基线吸气肌功能与平衡能力呈正相关（p < 0.05），IMT引起的吸气功能改善（最大吸气压力提高23.3%，吸气峰值流速提高8.0%，最大吸气峰值功率提高14.9%）与平衡能力改善（迷你平衡评估系统测试提高10.6%）相关，年龄最大的参与者（76 - 85岁）改善最为显著（17.0%，p < 0.05）。总之，无论是否进行IMT，吸气功能与平衡能力之间均存在正相关，吸气肌功能改善越大，平衡能力改善越大。
