A University at Buffalo study followed over 5,000 women aged 63 to 99 for eight years, revealing a significant link between muscle strength and reduced mortality risk. The research focused on two easily measurable indicators of strength: grip strength and the ability to perform unassisted sit-to-stand chair raises. Women with higher grip strength and faster chair stand times experienced significantly lower death rates.

Why it matters

This study suggests a need to rebalance public health messaging, which has traditionally heavily emphasized aerobic exercise. The findings highlight the crucial connection between strength, physical activity, and healthy aging, underscoring the importance of incorporating strength training alongside traditional cardio recommendations.

The details

Researchers found that a 7 kilogram increase in grip strength correlated with a 12% lower mortality rate, whereas faster chair stands showed a 4% reduction in mortality for every 6-second improvement. Grip strength and chair stands are routinely used in clinical settings to assess the older patients' strength levels. The study emphasizes that resistance can come from various sources, including using everyday objects like soup cans or books.

  • The University at Buffalo study was published in JAMA Network Open in 2026.

What they’re saying

“If you don't have enough muscle strength to gain up, This proves going to be hard to do aerobic activities, such as walking.”

— Dr. Michael LaMonte, Lead author of the study

“Healthy aging probably is best pursued through adequate amounts of both aerobic and muscle-strengthening physical activities.”

— Dr. Michael LaMonte, Lead author of the study

What’s next

Researchers emphasize the importance of older adults consulting with their healthcare providers before starting any new exercise program, and considering working with a physical therapist or exercise specialist to ensure safety and proper technique.

The takeaway

This research underscores a shift towards a more holistic approach to healthy aging, highlighting the crucial role of muscle strength in enabling physical activity and overall longevity. Future public health initiatives may increasingly incorporate strength training alongside traditional aerobic exercise recommendations.
