A 36-week community multicomponent exercise programme (the Vivifrail model, combining strength, balance, gait and endurance work) raised Short Physical Performance Battery scores by a mean of 1.33 points (Cohen's d = 0.96) in 92 adults averaging 75.9 years, with improvements in Timed Up and Go, handgrip strength, 6-metre walk time and cognition. Probable sarcopenia (EWGSOP2) fell from 17.4% to 5.4%, and 72.8% reached a substantial clinically important difference. A prior cohort (n = 86) showed similar effects; pooled elevated fall risk dropped from 19.7% to 11.2%.
The replication across two cohorts adds some reassurance, and a 1.33-point SPPB gain is meaningful, since changes of roughly one point are linked to lower disability and mortality risk in older populations. The findings sit comfortably alongside the larger body of randomised evidence, including the Vivifrail and LIFE trials, showing that supervised multicomponent training improves function in older adults. The main weakness is design: a single-arm service evaluation has no control group, so regression to the mean, learning effects on timed tests, seasonal variation and participant selection could all inflate gains. The 88% female sample and community setting limit generalisability, and the sarcopenia figure is based on probable sarcopenia (grip strength) rather than confirmed muscle mass. This is a preprint that has not been peer reviewed, so results may change. Editorially, it is confirmatory and incremental, but it offers practical real-world support for structured, progressive resistance and balance training as a routine option for older adults at risk of frailty.
