How a 92-year-old sprinter maintains the fitness of someone half her age

At 92, Italian sprinter Emma Maria Mazzenga is drawing global attention not only for her track achievements but also for what researchers say may be an extraordinary example of healthy ageing. Scientists studying the retired schoolteacher have found physical traits more commonly associated with people decades younger, challenging long-held assumptions about age-related decline.

Researchers examining Mazzenga’s muscles, nerves and cellular function reportedly discovered that her aerobic capacity rivals that of athletic women far younger than her age. Even more striking, the mitochondria in her muscle cells — responsible for producing energy — appear to function at levels typically seen in much younger adults.

Experts believe her condition highlights the powerful role of regular exercise in slowing the effects of ageing. Exercise physiologist Simone Porcelli described her as an inspiring example of how physical activity can help preserve fitness and function well into later life.

Mazzenga’s routine is built on consistency rather than extreme training. She exercises around three times a week, focusing on sprint workouts, daily walks and light strength exercises, with sessions generally lasting less than an hour. Her diet centres on fish, eggs and vegetables, while still allowing occasional indulgences.

Her lifestyle closely reflects World Health Organization recommendations for older adults, which emphasise regular aerobic activity, strength training and reducing sedentary behaviour. Researchers hope insights from her case could help improve understanding of how exercise influences the ageing process and supports long-term health.
