Does prioritizing your fitness help protect your brain health?

Does prioritizing your fitness help protect your brain health?

We all want to protect our brains and bodies from disease and decline and stay sharp and vibrant throughout the decades. Regular exercise is part of a healthy lifestyle, and it brings a range of benefits, from lowering blood pressure to perking up your mood and prompting the release of feel-good endorphins. Your training habits can benefit your physical health and your brain health, too. For example, an interesting study showed that people who took part in aerobic fitness training had increased brain volume and white and gray matter. 

Physical activity can sharpen problem-solving, memory, and learning and reduce depression or anxiety. Another study concluded that cognitive decline is nearly twice as common in adults who are inactive compared to active adults. In a recent study, researchers wanted to look at how exercise lowered the risk of dementia. Let’s take a look at the study and the results.

In a study published in the British Journal of Sports Medicine, the researchers wanted to investigate how cardiorespiratory fitness affected the risk of dementia, taking genetic predisposition into account. The researchers looked at data from 61,214 adult participants who didn’t have dementia. 

The researchers identified dementia cases through medical records and assessed genetic predisposition. They used a six-minute submaximal cycling test to determine the participants’ cardiovascular fitness and estimate maximal oxygen consumption or VO2 max. The participants also took neuropsychological tests to evaluate their reaction time, processing speed, and memory. The researchers looked closely at the data to analyze the relationship between cardiovascular fitness and genetic predisposition.

In conclusion, the researchers reported a positive association between a high cardiovascular fitness level and cognitive function across all age groups. High cardiovascular fitness levels were associated with a 40% lower overall risk of dementia and a delayed dementia onset by 1.48 years on average. For individuals with a high predisposed risk of dementia, high cardiovascular fitness was associated with a 35% lower risk of dementia.

What is cardiovascular fitness?

Cardiovascular fitness refers to your ability to deliver oxygen to your working muscles and your heart. Another interesting study revealed that higher cardiovascular fitness levels were linked with a lower risk of heart and blood vessel disorders and complications.

What we can learn from this research

This research shows that having good fitness levels could lower your risk of dementia, delay its onset by up to 18 months, and enhance your cognitive performance. This study shows us that even those with a higher genetic risk of developing dementia can lower that risk with regular exercise. Prioritizing your fitness helps protect your brain health, heart health, and more.

Share your health and fitness questions for Devi Sridhar, Mariella Frostrup, and Joel Snape

There’s no bad time to take a more active interest in your health, but the new year, for lots of us, feels like a fresh start. Maybe you’re planning to sign up for a 10k or finally have a go at bouldering, eat a bit better or learn to swing a kettlebell. Maybe you want to keep up with your grandkids — or just be a little bit more physically prepared for whatever life throws at you.

To help things along, Guardian Live invites you to a special event with public health expert Devi Sridhar, journalist and author Mariella Frostrup, and health and fitness columnist Joel Snape. They’ll be joining the Guardian’s Today in Focus presenter Annie Kelly to discuss simple, actionable ways to stay fit and healthy as you move through the second half of life: whether that means staying strong and mobile or stressing less and sleeping better.

To make the whole event as helpful as possible, we’d love to hear from you about what you find most challenging — or confusing — when it comes to health and exercise. What should you actually be eating, and how are you going to find the time to make it? What sort of exercise is best, and how often should you be doing it? Is Pilates worth the effort — and should we really all be drinking mugfuls of piping hot creatine?

Whether your question is about exercise, eating, or general wellness, post it below and we’ll put a selection to our panel on the night.
