Emma Maria Mazzenga has the world wondering how she does it, and scientists studying her muscles, nerves, and mitochondria, the cell powerhouse, to gain a better understanding of how she’s able to keep running at 92 and beating her own records. She’s simply amazing. Emma dislocated her shoulder during a race in Germany a dozen years ago because she threw herself ahead of a competitor to win the race.

“The woman next to me was about to overtake me,” Mazzenga said. She was 79 at the time. “Now, Mazzenga, who lives in Padua, Italy, is running out of competition,” wrote the Washington Post in a special report about her. “At 5-foot-1, she’s an elite sprinter with four age-group world records to her name — and very few opponents to race against.”
