Participant Flow

Participants were recruited from the community using flyers, posters, and mass mailings. The eligibility criteria included men and women aged 70 years or older, who were at high risk for mobility disability based on lower extremity functional limitations measured by the Short Physical Performance Battery (SPPB) with a score of 9 or lower out of 12, and not participating in a structured exercise program, and not using strength exercises in the past 6 months.

A total of 54 participants were assessed for eligibilty and 33 were excluded ( 23 not meeting inclusion criteria (18 SPPB out of range) and 10 withdrew pre-randomization). Twenty-one participants met eligibility criteria and were subsequently randomized into 2 groups

Measure
Resistance Training Group (RT)
The resistance training intervention will include a full body, resistance training performed three days per week. The intensity, volume, tempo, and progression will be based on the Federal Physical Activity guidelines Resistance Training: The intensity, volume, tempo, and progression will be based on the Federal Physical Activity guidelines. The resistance training exercises will include mainly multi-joint exercises using selectorized machines. Each session will include upper body exercises (Chest Press, Shoulder Press, Seated Rows, Bicep curls, and Tricep Extensions) and lower body exercises (Leg Press, Leg Extension and Leg Curls, and Calf raise) that will be tailored to the participant needs.
Successful Aging
The comparator group will meet for stretching and health education classes every 2-5 weeks up to 7 total visits. Successful Aging: The successful aging will attend stretching and health lectures as a group . The topics might include, medication management, disease management (e.g. blood pressure, diabetes, arthritis, dementia, pain management, diet) and other health related matters.

SECONDARY outcome

Timeframe: Baseline and Week 15

Population: We want to analyze the correlation between DXA ALM and D3Cr muscle mass. Hence, the two groups are combined to calculate the correlation of DXA ALM compared to D3Cr muscle mass in all the participants rather than individual groups.
