Community Smart Aging Model - Resistance Training

Condition(s) studied

Investigational drug(s) / intervention(s)

Smart Community-Based Resistance Training: Participants complete a 32-week resistance training program using elastic bands. Sessions occur 3 times per week, lasting 40-60 minutes each. The training intensity progressively increases from 50-60% of 1RM to 70-80% of 1RM. A smart health bracelet and mHealth application monitor heart rate and adherence in real-time.

Routine Health Education: Participants maintain their usual daily activities without structured resistance training. Participants attend monthly 60-minute group health education lectures. The lectures cover osteoporosis knowledge, physical activity benefits, and fall prevention strategies.

Study summary

This clinical trial aims to evaluate the effectiveness of a smart community-based resistance training program in older adults aged 60 and older with primary osteoporosis. The main questions it aims to answer are:

Does the 32-week smart resistance training improve lumbar spine bone mineral density (BMD)? Does the training improve lower extremity physical function? Researchers will compare the smart resistance training group with a routine health education control group to see if the resistance training effectively improves bone health and physical capabilities.

Participants will:

Be randomly assigned to either the resistance training group or the health education group.

If in the training group: Wear a smart health bracelet and complete 40 to 60 minutes of elastic band resistance training 3 times a week for 32 weeks, with guidance from smart devices and community staff.

If in the health education group: Maintain usual daily activities and attend a monthly group health education lecture on osteoporosis.

Complete clinical assessments, including bone density scans (DXA), physical performance tests, and questionnaires at the start, at 16 weeks, and at 32 weeks.

Enter a 12-month observational follow-up phase after the 32-week intervention to evaluate the long-term sustainability of the outcomes.

Eligibility

Primary outcome measure(s)

• Lumbar Spine Bone Mineral Density (BMD) — Baseline ，16 weeks ，32 weeks and Follow-up ended (12 months after the 32-week intervention).
  Measured by Dual-energy X-ray Absorptiometry (DXA). The absolute BMD value is reported in g/cm².
• Short Physical Performance Battery (SPPB) Score — Baseline, 16 weeks, 32 weeks and Follow-up ended (12 months after the 32-week intervention).
  The Short Physical Performance Battery (SPPB) assesses lower extremity function through three tests: static balance, 4-meter gait speed, and 5-time chair stand. The total score ranges from a minimum of 0 to a maximum of 12. Higher scores indicate better physical function and lower fall risk.
