- Primary Outcome Measures
Name Time Method Bone Mineral Density and Bone Mineral Content will be measured by Dual energy X-ray absorptiometry and periheral quantitative computed tomography[At baseline and at 6 months, following commencement of intervention];Muscle Cross Sectional Area will be measured using Dual energy X-ray absorptiometry and peripheral quantitative computed tomography[Baseline, 3 Months, and 6 months following commencement of intervention];Muscle Function will be measured by:<br>a) muscle strength (leg and arm) using 1 Repetition Maximum (RM)<br>b) muscle power measure as the muscle force/time to lift a load at 20%, 40%, 60%, 70%, 80% and 90% 1 RM[Baseline, 3 Months, and 6 months following commencement of intervention]
- Secondary Outcome Measures
Name Time Method Balance will be measured using static balance and dynamic posturography, which is measured on a Chattecx Balance Platform. The platform moves in an anterior-posterior (AP) direction (forward-backward) for 30 s under open and eyes closed conditions. The platform also moves in AP tilt (up and down). for 30 s under open and eyes closed conditions. Static balance is measure by single leg stand for 30 s under eyes open and eyes closed conditions.[Baseline, 3 Months, and 6 Months following commencement of intervention];Physical Performance measured by:<br>a) sit to stand<br>b) stair climb)<br>c) habitual gait speed<br>d) maximal gait speed<br>e) total distance covered in 6 minutes[Baseline, 3 Months, and 6 months following commencement of intervention']
