It often happens gradually. Grocery bags feel heavier, getting up from the couch takes more effort, and the body no longer responds quite the same way it once did. Most people brush it off as a normal part of aging.
But researchers from the University at Buffalo now believe those small changes may reveal far more than expected.
A new study suggests muscle strength could be closely connected to both long-term health and lifespan, reports Science Daily.
Small tests, big answers
The study, published in JAMA Network Open, followed more than 5,000 women between the ages of 63 and 99 over an eight-year period.

Researchers measured participants’ grip strength and how quickly they could rise from a chair several times without assistance.
Women with greater strength showed a significantly lower risk of death during the study period.
The findings remained consistent even after researchers accounted for physical activity, fitness, inflammation, and body size.
More than just exercise
According to the researchers, muscle strength may play a much larger role in healthy aging than many people realize.

The ability to move freely and handle everyday tasks is closely linked to both independence and overall health later in life.
One of the study’s most notable findings was that even women who did not meet official exercise guidelines still appeared to benefit from having higher levels of strength.
Researchers say the results could lead to greater focus on simple strength-building activities as part of future public health advice for older adults.
