Abstract
Purpose
The purpose of this study was to review the effects of physical activity on musculoskeletal outcomes in older Koreans.
Methods
Experimental studies were retrieved from the search engines (PubMed, CINAHL, PsycINFO, Cochrane, RISS, KISS, and KoreaMed). The selected studies for analysis were 27 articles of musculoskeletal outcomes (gait, muscle strength, flexibility, balance, grip strength, endurance, body fat, and weight) from 515 articles.
Results
The most common type of physical activity was a resistance exercise. There were significant improvements in gait (71.4%), muscle strength (86.7%), flexibility (63.6%), balance (72.2%), grip strength (71.4%), endurance (71.4%), body fat (57.1%), and weight (28.6%). The activity programs that apply over 150 minutes a week showed greater improvement of 69.5% than 65.0% from those did not meet the guidelines totally.
Conclusion
Based on the review, we conclude that regular physical activity in the elderly may improve the musculoskeletal outcomes. To be more effective programs, it is necessary to meet the guidelines of 150 minutes a week or 30 minutes of moderate-intensity activities on 5 days per week for the elderly.

Summary Statement
▪ What is already known about this topic?
Older people in Korea are still inactive in their daily life. Individualized physical activity for the elderly can promote their health status.
▪ What this paper adds?
Regular physical activity may improve older adults' gait, muscle strength, flexibility, balance, grip strength, endurance, and body fat. To be more effective, it is necessary to meet the guidelines of 150 minutes a week or 30 minutes of moderate-intensity exercise on 5 days per week for the elderly.
▪ Implications for practice, education and/or policy
This study gives specific information to know the health benefits of physical activity regarding musculoskeletal outcomes. Physical activity for the elderly should be performed on the basis of tailored instructions. Well-designed research is more effective to show the effects of interventions.
