We aimed to examine the outcomes of our novel multicomponent lower extremity training (MLT) technique on physical function in older adults. Participants were randomly divided into a training group (TG) or a control group (CG). The TG (4 men, 14 women) received MLT for 24 weeks, once per week. MLT contains strength, balance, and flexibility components. The CG (5 men, 10 women) did not receive any training for 24 weeks. Nine lower extremity range of motions (ROMs; hip flexion, hip abduction, hip adduction, hip extension, internal and external hip rotations, knee flexion, ankle dorsiflexion, and ankle plantar flexion) and two muscle strength assessments (knee extension and flexion) were collected. Physical performance tests were also performed, including the functional reach test, timed up and go test (TUGT), and five times sit-to-stand test (FTSST). After 24 weeks, significant increases were observed in the TG in all ROMs (with the exception of knee flexion), knee extension strength, and performance in the TUGT and FTSST. MLT significantly improved ROM, muscle strength, and physical performance in healthy older adults. We suggest that it is an efficacious intervention in the maintenance and improvement of mobility and functional independence in healthy older adults.

我们旨在研究新型多组分下肢训练（MLT）技术对老年人身体功能的影响。参与者被随机分为训练组（TG）或对照组（CG）。训练组（4名男性，14名女性）接受为期24周的MLT训练，每周一次。MLT包括力量、平衡和灵活性训练。对照组（5名男性，10名女性）在24周内未接受任何训练。收集了九项下肢活动范围（ROM；髋关节屈曲、外展、内收、伸展，髋关节内外旋，膝关节屈曲，踝关节背屈和跖屈）和两项肌肉力量评估（膝关节伸展和屈曲）的数据。还进行了身体性能测试，包括功能性伸展测试、计时起立行走测试（TUGT）和五次坐立测试（FTSST）。24周后，训练组在所有ROM（膝关节屈曲除外）、膝关节伸展力量以及TUGT和FTSST测试中的表现均有显著提高。MLT显著改善了健康老年人的ROM、肌肉力量和身体性能。我们认为，这是一种对维持和改善健康老年人的活动能力和功能独立性有效的干预措施。日本大学医学综合研究中心临床试验注册编号，UMIN000037463。https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000041955 。
