Why Grip Strength Matters for People
Share
As people live longer, it's important to focus not just on how long we live, but how well we live. For adults over 90, staying independent and mentally sharp can be a real challenge. A recent study from Brazil has found something surprising: your handgrip strength – how strongly you can squeeze something – may help protect your brain and keep you doing everyday tasks like dressing, eating, and bathing.
What Did the Study Look At?
The study included 150 people aged 90 and above. The researchers measured three key things:
- Cognitive function – how well their memory, attention, and thinking skills were working
- Functional independence – how well they could do basic daily activities without help
- Handgrip strength – using a special device to measure how strongly they could squeeze
The big question was: Does stronger grip strength help older adults stay more independent, even if their thinking skills are declining?
The Key Finding
Yes, it does! The researchers found that when older adults had low grip strength, their cognitive abilities played a bigger role in how independent they were. But if their grip strength was higher, the impact of cognitive decline on their independence was less severe.
In simpler words: if you’re very old and physically weak, your brain has to work harder to help you stay independent. But if you still have some muscle strength, your body can do more on its own, even if your memory or thinking isn't perfect.
What Are the Grip Strength Benchmarks?
The study found two important numbers:
- For men, handgrip strength below 24.4 kg meant cognition had a strong effect on independence.
- For women, the cutoff was 17.3 kg.
If grip strength was above these numbers, cognitive decline didn’t lead to as much trouble with daily tasks.
Why Is Grip Strength So Important?
Grip strength is often used by doctors as a quick and easy way to estimate overall muscle strength. It’s cheap, fast, and doesn’t require special equipment or training.
More importantly, it’s linked to many aspects of health:
- Risk of falling
- Hospitalization
- Cognitive decline
- Even early death
Now, this study adds another benefit: helping older adults stay independent, even with some cognitive loss.
What Can Older Adults Do?
Even if someone is in their 80s or 90s, it’s not too late to start building or maintaining muscle strength. Here are some practical tips:
- Do hand exercises – Squeezing a soft ball, using resistance bands, or doing wrist curls can help.
- Stay active – Regular movement like walking, gardening, or chair exercises keeps muscles strong.
- Eat enough protein – Muscle needs building blocks, and protein-rich foods like eggs, dal, paneer, or lean meat can help.
- Lift light weights – Under supervision, even light resistance training can maintain muscle function.
- Talk to a doctor or physiotherapist – They can suggest safe exercises based on one’s ability.
Final Thoughts
Living to 90 or even 100 is a gift, but it comes with challenges. This study shows that a strong body, even something as simple as a strong grip, can help make aging easier by reducing the burden on your mind. So, if you're caring for an elderly loved one – or planning your own healthy aging – don't ignore those muscles. A little strength can go a long way.
Staying strong might just be the secret to staying sharp and independent – even in your 90s.
