To The Editor: Dr Volpi and colleagues1 found that differences in basal muscle protein
turnover in older and younger men do not explain age-related sarcopenia. This
conclusion contradicts our collective results, which have found age-related
differences in muscle protein synthesis.2- 5
We suggest several reasons for these differences.
