Study Overview
Brief Summary
The overall aim of the proposed project is to improve muscle strength in older adults with possible sarcopenia by promoting home-based progressive resistance exercise. The target population for health talks is community-dwelling older adults. A Three monthly home-visits and weekly phone calls will be made. A waitlist randomised controlled trial will be conducted to evaluate effectiveness, and qualitative feedback will be collected from participants. A pilot study will be conducted first.

Inclusion Criteria
- •The inclusion criteria are:
- •Aged 65-89;
- •Possible sarcopenia (defined by AWGS 2019);
- •No cognitive impairment (Abbreviated Mental Test score ≥8); and
- •No communication problems.
Exclusion Criteria
- •having engaged in a structured exercise programme in the past 6 months or planning to do so within the intervention period;
- •mobility-limiting injury of the hands or lower limbs, surgery or hospitalisation within the intervention period;
- •contraindications such as musculoskeletal/cardiorespiratory disorders, or any advanced diseases that inhibit them from exercising.
Arms & Interventions
Intervention
The intervention is a 12-week home-based resistance training programme with phased progression. The intervention will have three phases: (i) an initial phase focused on training the target muscle(s)/movements with minimal or no external weight; (ii) an intermediate phase targeting muscle strength with increased practice resistance; and (iii) an advanced phase targeting the further enhancement of muscle strength by challenging multiple muscle groups. Each phase will involve exercises targeting the trunk, back, hip, upper-limb and lower-limb muscles.
Intervention: Exercise (Behavioral)
Waitlist control
The waitlist control participants will start the intervention 12 weeks after the baseline assessment.
Intervention: Exercise (Behavioral)
Outcomes
Primary Outcomes
Change in lower-limb muscle strength at 12 weeks from baseline
Time Frame: 12 weeks after baseline
Measured by Short Physical Performance Battery (SPPB), higher score indicates better performance
Secondary Outcomes
- Change in lower-limb muscle strength at 24 weeks from baseline(24 weeks after baseline)
