New research from the University of Birmingham reveals that older adults who've never joined long-term exercise programs can build muscle mass as effectively as highly trained master athletes of the same age. This underscores the power of resistance training, like weightlifting, for beginners at any stage of life.
The study compared muscle-building potential in two groups of older men. 'Master athletes'—lifelong competitors from the 1970s and 1980s who still compete at elite levels—were matched against healthy peers of similar age with no history of structured training.
Participants sipped 'heavy' water as an isotope tracer, then trained on a resistance machine. Researchers analyzed muscle biopsies taken 48 hours before and after to track protein synthesis and muscle response.
Researchers anticipated superior results from the athletes due to decades of training. Surprisingly, both groups showed identical muscle-building responses to exercise.
'Our findings prove it doesn't matter if you've skipped regular exercise your whole life—you can still reap major benefits by starting now,' says the lead researcher. 'Lifelong fitness is ideal for overall health, but beginning later still fights age-related frailty and weakness.'
