Maintaining physical fitness is important for health of the elderly. How to implement an effective and efficient model is a practical issue. A healthy physical fitness promotion program with machine-assisted exercises was designed for elderly and executed in a community in 2015 and 2016. The program was implemented for 10 to 12 weeks with two (group 1) or three (group 2) sessions per week, and functional fitness tests were conducted before, at the end, and 3 months after the training. This study is to investigate the effectiveness of machine-assisted physical fitness promotion program for the community elderly.
A retrospective analysis was conducted on the participants' data, including sex, age, height, weight, waist-hip ratio, grip strength, back stretch, chair sit-and-reach, 30-second chair stand, 30-second arm curl, 2-minute step, single-leg standing, 8-ft up-and-go, and body composition. The differences in test results before, at the end, and 3 months after the training and the percentage change at different time intervals between the two groups were compared.
After training, body mass index in group 2 and the test completion time for 8-ft up-and-go in group 1 decline significantly; furthermore, significant increase was noted in the height and number of times of 2-minute step in both groups, and grip strength, number of times of their 30-second arm curl, and 30-second chair stand in group 2. The training effect sustained 3 months after the training in height and number of times of 2-minute step in both groups, and grip strength, number of times of their 30-second arm curl, and 30-second chair stand in group 2.
This study discovered that 10 to 12 weeks of machine-assisted exercise training can improve the elderly community members' body composition, muscle strength, muscle endurance, agility, dynamic balance, and cardiorespiratory endurance. Moreover, with three sessions per week, its effects were even maintained for 3 months after the training.
保持身体健康对于老年人的健康至关重要。如何实施一种有效且高效的模式是一个实际问题。我们为老年人设计了一个机器辅助锻炼的健康体能促进计划，并于 2015 年和 2016 年在社区中实施。该计划实施了 10 到 12 周，每周两次（第 1 组）或三次（第 2 组），在培训前、结束时和培训后 3 个月进行功能体能测试。本研究旨在调查机器辅助体能促进计划对社区老年人的有效性。
对参与者的数据进行回顾性分析，包括性别、年龄、身高、体重、腰臀比、握力、背部伸展、坐立前伸、30 秒坐站、30 秒手臂卷曲、2 分钟踏步、单腿站立、8 英尺起立-行走和身体成分。比较两组在培训前后和培训后 3 个月的测试结果差异，以及不同时间间隔的百分比变化。
培训后，第 2 组的体重指数和第 1 组的 8 英尺起立-行走测试完成时间显著下降；此外，两组的身高和 2 分钟踏步次数均显著增加，第 2 组的握力、30 秒手臂卷曲次数和 30 秒坐站次数也显著增加。培训后 3 个月，两组的身高和 2 分钟踏步次数，以及第 2 组的握力、30 秒手臂卷曲次数和 30 秒坐站次数的训练效果仍在持续。
本研究发现，10 到 12 周的机器辅助运动训练可以改善老年人的身体成分、肌肉力量、肌肉耐力、敏捷性、动态平衡和心肺耐力。此外，每周进行三次训练，其效果甚至可以在训练后 3 个月维持。
