In large trials, exercise made serious walking disability less common in people aged 70 or older who already had limited mobility.
How strong your muscles are says something about your risk of dying, no matter how active you are. That is the core argument of an opinion piece calling for muscle health to become its own goal in public health policy. The biggest gains, it says, come from strength training or mixed programs, not from aerobic exercise alone.
As evidence, the author points to large trials where people were assigned at random. In the LIFE trial, 1,635 inactive adults aged 70 to 89 did walking, strength and flexibility training for 2.6 years on average. Serious walking problems struck 30.1 percent of them, compared with 35.5 percent in a group that got health education. In the SPRINTT trial of 1,519 frail adults aged 70 or older, walking disability became less common only among those who scored poorly on a physical test at the start.
This is a viewpoint, not a systematic review: the studies were picked to support the argument. Most exercise trials on age-related muscle loss also last only about 12 weeks. Direct data on whether such programs pay off financially remain sparse.
