This study builds upon our group's work where we characterized cardiovascular and skeletal muscle structure and function of community-based older adults. In this proposal, we will identify n=100 participants with cardio-sarcopenia phenotype. Comparing between participants with baseline low versus high levels of physical activity, we will investigate temporal changes in their cardiovascular, skeletal muscle, biomarkers and BMI data, over a six- to twelve month period. Physical activity will include subjective self-reported physical activities and objective measures of aerobic capacity. Their physical activity levels will be verified bi-monthly via physical activity and cardiac health application that measures these markers. Pertinent fluctuations in diet, lifestyle, risk factors and biomarkers will also be recorded.
