Step speed may predict longevity in older adults, Ben-Gurion University study finds

A new study from Ben-Gurion University of the Negev suggests that how quickly older adults can step may predict how long they will live. Researchers found that step initiation speed, particularly when combined with a simultaneous cognitive task, is a significant indicator of longevity.

The study, published in the journal Gerontology, was led by Prof. Itshak Melzer and involved analyzing balance data from 120 elderly participants. The team utilized a force platform, a biomechanical instrument, to measure dynamic balance, specifically focusing on voluntary step execution. This approach aims to supplement traditional methods of predicting survival, such as chronological age and the number of chronic illnesses.

While current clinical examinations for life expectancy often rely on age and health conditions, physical indicators like walking speed are increasingly recognized as strong predictors of overall health and independence. The research team sought to enhance this clinical toolkit by evaluating whether postural sway and voluntary step execution could forecast survival rates over an extended follow-up period. Although challenges like the need for specialized equipment exist, the researchers noted that emerging technologies, such as wearable systems, could make this type of measurement more accessible in the future.
