Brief Summary

Background: Muscle power, defined as the rate at which muscular force is generated to produce movement, declines more rapidly with age than muscle strength. The decline in lower extremity muscle power is associated with reduced functional independence, impaired mobility, and an increased risk of falls among older adults. While power training has been shown to improve muscle power, balance, and functional abilities, the feasibility and effectiveness of home-based interventions have not been thoroughly investigated. Purpose: The aim of this study is to investigate the effects of home-based lower extremity muscle power training program on functional muscle and balance performance in older adults. Methods: This is a single-blind, randomized controlled trial. Forty community-dwelling older adults will be recruited and randomly assigned to the experimental group (n=20) and control group (n=20). Participants in the experimental group will complete 24 sessions of home-based lower extremity muscle power training targeting the lower limb muscle groups in 8 weeks. The training intensity will be progressively adjusted according to participants' performance. Participants in the control group will maintain their daily activities. In addition, both groups will receive health education. Primary outcomes include functional muscle power measured by the Four-Step Stair Climb Power Test, functional muscle strength measured by Five Times Sit-to-Stand Test, and the functional balance performance measured by the Mini-BESTest, and Timed Up and Go Test. The fall confidence, as the secondary outcome, will be measured by Falls Efficacy Scale International. Statistical analysis: The SPSS® version 29 will be used for statistical analysis. Independent-t-test or chi-square test will be conducted to compare the baseline demographic characteristics between groups. Two-way repeated measure ANOVA will be used to compare the differences between groups and times, post-hoc analyses will be performed using Tukey's test. The significance level is set at 0.05.

Outcome Measures

Primary Outcomes (4)

• Functional muscle performance-muscle power

  The Four-Step Stair Climb Power Test is used for measurement, where participants rapidly ascend four steps while the required time is recorded. This test is designed to assess lower limb muscle power.

  From baseline to the end of treatment at 8 weeks

• Functional muscle performance-muscle strength

  The 5 Times Sit-to-Stand Test is used for measurement, where participants quickly and continuously perform five sit-to-stand movements while the required time is recorded. This test is designed to assess lower limb muscle strength.

  From baseline to the end of treatment at 8 weeks

• Balance

  The Mini-BESTest (Balance Evaluation Systems Test) is used for measurement. This test includes anticipatory control, reactive postural control, sensory orientation, and dynamic gait, allowing for the assessment of balance abilities related to postural control.

  From baseline to the end of treatment at 8 weeks

• Timed Up and Go Test

  The Timed Up and Go (TUG) Test is conducted at both a normal and fast pace to assess the balance and mobility of community-dwelling older adults in functional activities.

  From baseline to the end of treatment at 8 weeks

Secondary Outcomes (1)

• Fall confidence

  From baseline to the end of treatment at 8 weeks
