Strength training benefits misunderstood: no 45% dementia cut, Pilates not a full replacement

A recent analysis clarifies that the claim "strength training reduces dementia risk by 45%" is inaccurate. The 45 percent figure originates from the Lancet Commission on Dementia Prevention, which estimates that eliminating all 14 identified risk factors worldwide could prevent up to 45 percent of dementia cases. It does not reflect the effect of strength training on an individual’s risk. Separate research shows that regular strength training can reduce frailty among US veterans, but it does not directly lower dementia incidence.

Sports scientist Dr. Mona Kellner explains that Pilates resembles a form of strength‑endurance training and offers benefits for core stability, mobility and coordination. However, because Pilates lacks progressive overload, it cannot fully replace traditional strength training when the goal is to increase muscular strength or mass, though it serves as a valuable complement.
