Brief Summary
This randomized controlled trial investigated the effects of a four-week moderate-intensity resistance training program on diaphragm thickness, hepatic fat density, and health-related quality of life in healthy community-dwelling older men aged 60-75 years. Thirty participants were randomly assigned to a resistance training group or control group. Diaphragm thickness and hepatic attenuation were assessed using non-contrast computed tomography, and quality of life was evaluated using the SF-12 questionnaire. The primary outcome was change in diaphragm thickness. Secondary exploratory outcomes included hepatic fat density and SF-12 physical and mental health scores.

Resistance Training Group (RT)
EXPERIMENTALParticipants performed supervised resistance training three times per week for four weeks. Each session lasted 30-40 minutes and included: Lower body exercises (sit-to-stand, step-ups, glute bridge) Upper body exercises (wall push-ups, resistance band row, biceps curl) Core exercises Breathing exercises (diaphragmatic breathing, pursed-lip breathing) Warm-up protocol (10 minutes dynamic mobility) Intensity: Borg RPE 12-15 Rest interval: 60 seconds between sets
CONTROL
NO INTERVENTIONParticipants maintained their usual daily routines without structured exercise intervention.
Interventions
Structured Moderate-Intensity Resistance Training
Participants maintained their usual daily routines without structured exercise intervention.

- Masking Details
- Participants were not blinded to group allocation because of the nature of the exercise intervention. The personnel delivering the intervention were also aware of group allocation. Outcome assessors, including the radiologist responsible for CT-based diaphragm thickness assessment, and the statistician were blinded to group allocation.
