结局指标
主要结局
Change in muscle mass, strength and performance
时间窗: Measured at baseline and after 12 weeks (end-of-study visit)
Change in muscle is mass measured by DXA. Muscle strength and performance are measured by several physical tests such as repeated chair stands, handgrip strength, step stair test and strength in legs and torso and gait speed and are considered as the clinical relevant outcomes.
次要结局
- Changes in levels of inflammatory markers(Measured at baseline and after 12 weeks (end-of-study visit))
