Patients are stratified by centre (NCC/SGH, NUH), menopausal status, ER/PR status, body fat/muscle ratio.
Cardiorespiratory fitness, muscle strength, level of routine daily physical activity, body fat/muscle ratio are monitored during the study period.
Blood is collected at baseline, 8 weeks, 16 weeks, 24 weeks, 52 weeks, then annually for 4 times.
