There's separate research as well into how much, if any, exercise can slow/reduce Sarcopenia (https://en.wikipedia.org/wiki/Sarcopenia https://en.wikipedia.org/wiki/Sarcopenia). So they are at least researching it separate from simple correlation as well. "Exercise is of interest in treatment of sarcopenia; evidence indicates increased ability and capacity of skeletal muscle to synthesize proteins in response to short-term resistance exercise.[18] A 2009 Cochrane review also found evidence that in older adults progressive resistance training can improve physical performance (gait speed) and muscular strength,[19] which are two key components of sarcopenia."
