93-Year-Old Runner Shatters Aging Myths
18 Oct
Summary
- At 93, Emma Mazzenga holds a world record for the 200-meter dash in her age category.
- Scientific studies reveal her muscle fibers are exceptionally large for her age.
- She continues rigorous training, demonstrating exercise's power to slow aging.
Emma Maria Mazzenga, now 93, continues to defy expectations in the world of athletics, holding the current 200-meter world record for the women's over-90 category at 50.33 seconds, achieved in 2024 at age 91. Her dedication to training three times weekly, focusing on short, intense repeats, has drawn scientific attention.
Researchers have noted that Mazzenga's maximal oxygen consumption is comparable to that of individuals in their 50s. More astonishingly, her slow-twitch muscle fibers are as large as those of a 20-year-old, a unique finding that scientists believe helps compensate for age-related loss of fast-twitch fibers.
This research, part of the Trajector-Age project, investigates how exercise can mitigate the physical decline associated with aging. Mazzenga's case highlights that much of what is considered inevitable aging may, in fact, be influenced by lifestyle and consistent physical activity over decades.
