At 92, she’s as fit as someone half her age

illuminem summarises for you the essential news of the day, reviewed by our editorial team. Read the full piece on The Washington Post or enjoy below:

🗞️ Driving the news: Emma Maria Mazzenga, almost 93, is a world-record-holding sprinter and subject of studies on elite aging
• Her cardiorespiratory fitness, muscle function, and mitochondrial health resemble that of active people decades younger, offering new insights into how exercise may counteract age-related decline

🔭 The context: Mazzenga trains three times per week with high-intensity sprints and light resistance work
• Muscle biopsies and lab tests conducted at the University of Padua and the University of Wisconsin show her aerobic capacity, nerve-muscle connectivity, and slow-twitch fiber health are exceptional
• Fast-twitch fibers show typical age-related atrophy, but overall performance allows her to set records in 60‑, 200‑, and 400‑meter events for her age group
• Researchers are examining how training, genetics, and lifestyle combine to produce her longevity and athleticism

🌍 Why it matters for the planet: Promoting active aging through exercise could reduce healthcare resource consumption and energy-intensive interventions associated with age-related illnesses, contributing to sustainable public health outcomes

⏭️ What’s next: Mazzenga will undergo repeat testing from ages 91 to 93 to track physiological changes
• Researchers aim to refine exercise strategies that optimize healthspan and muscle resilience in older populations, including potential guidance for population-level interventions

💬 One quote: “Masters athletes stand as living proof that passion, perseverance and discipline know no age limit.” – Hirofumi Tanaka, University of Texas at Austin

📈 One stat: Mazzenga’s aerobic capacity and oxygen delivery to muscles are comparable to active women in their 30s, despite being nearly 93
