Higher Cardiorespiratory Fitness Lowers Dementia Risk, Delays Onset: Study
A recent study has revealed a significant link between cardiorespiratory fitness (CRF) and a lower risk of dementia. The research shows that improving CRF not only reduces the chances of developing dementia but also helps delay its onset. Dementia is a term used to describe a range of symptoms affecting memory, thinking, and social abilities, often severe enough to interfere with daily life. With no cure currently available, understanding ways to reduce the risk of dementia is crucial, and this new study highlights the role of physical fitness in protecting brain health as we age.
What Is Cardiorespiratory Fitness?
According to the National Institute of Health, cardiorespiratory fitness refers to the efficiency with which the heart, lungs, and circulatory system supply oxygen to the muscles during sustained physical activity. It is often measured through maximal oxygen uptake (VO₂ max), which indicates how effectively the body utilises oxygen during exercise. Higher CRF levels are associated with better cardiovascular health, improved endurance, and enhanced overall well-being.
Achieving optimal CRF typically involves regular aerobic exercises such as brisk walking, running, cycling, or swimming. Beyond its cardiovascular benefits, CRF has been increasingly recognised for its role in brain health and resilience against cognitive decline.

Findings of the Study
The study, published in the British Journal of Sports Medicine, conducted by researchers across multiple institutions, followed over 500,000 participants in the UK Biobank cohort for nearly 13 years. During this period, researchers assessed participants’ cardiorespiratory fitness levels through indirect measures, such as self-reported physical activity and health metrics.
Key findings include:
- Individuals in the highest CRF category had a 42% lower risk of developing all-cause dementia compared to those in the lowest category.
- Higher CRF levels were associated with a delayed onset of dementia by an average of 1.7 years.
- The protective effects of CRF were consistent across age groups, suggesting that improving fitness is beneficial even in later life.
These results emphasise that maintaining physical activity and fitness can be a potent strategy to safeguard cognitive health.

Link Between Cardiorespiratory Fitness and Dementia
The relationship between CRF and dementia is rooted in the physiological and neurological benefits of regular exercise. High CRF levels positively influence the brain in several ways:
-
Improved Cerebral Blood Flow: Studies have shown that regular aerobic exercise enhances blood flow to the brain, ensuring a steady supply of oxygen and nutrients essential for optimal function.
-
Reduction in Inflammation: Exercise reduces chronic inflammation, a known contributor to neurodegenerative diseases such as Alzheimer’s.
-
Enhanced Neuroplasticity: The Journal of Sports and Health Science shows that exercising boosts the production of brain-derived neurotrophic factor (BDNF), a protein that supports the growth and maintenance of neurons. This helps maintain cognitive function and may slow the progression of dementia.
-
Mitigation of Cardiovascular Risk Factors: Hypertension, diabetes, and obesity are significant risk factors for dementia. Improving CRF helps manage these conditions, indirectly reducing dementia risk.
-
Stress and Mood Regulation: Regular physical activity lowers stress and improves mood by regulating hormones like cortisol. These factors are critical in protecting against cognitive decline.
Implications and Recommendations
The findings underscore the importance of public health initiatives that promote physical activity across all age groups. Simple lifestyle changes, such as incorporating daily walks, using stairs instead of lifts, or engaging in recreational sports, can improve CRF significantly.
For older adults or those with limited mobility, activities like yoga, tai chi, or light resistance training can also enhance fitness levels without excessive strain. The goal is consistent, moderate activity tailored to an individual’s capacity.
Conclusion
The link between cardiorespiratory fitness and dementia prevention adds another compelling reason to prioritise physical activity. As the global population ages, finding accessible and cost-effective strategies to reduce dementia prevalence is crucial. By fostering active lifestyles, society can pave the way for healthier, longer, and more fulfilling lives. The message is clear, taking steps today to improve fitness can lead to a sharper mind tomorrow.

Unlikely habit helped new parents shed 50 kilos
Books are getting Australians into the gym and keeping them there longer, and the benefits of this emerging health trend aren’t just physical – they’re mental too.
Listening to audiobooks and podcasts helped Yvonne Kong, 41, and her husband get back into fitness after becoming parents and lose a combined 50 kilos.

It also helped them broaden their minds and carve out a bit of “me time” in our busy modern world.
Audiobooks and podcasts have given Aussies the chance to turn exercise into a vehicle for learning, training their minds and bodies simultaneously. Some are even taking their e-readers and paperbacks to the gym (more on that later).
“Listening to a story while working out actually helped me stay motivated and more consistent,” Kong told nine.com.au.
Like many Aussies, she used to dread hitting the treadmill and constantly found herself counting down the minutes until her session was over.
That changed when she hit play on a true-crime podcast during a workout.
Kong got so caught up in the story she forgot about the timer on her treadmill until her workout was over.
“I did an hour treadmill course and actually finished it without noticing,” she said.

Since then, she’s found herself looking forward to exercising because it gives her an hour of dedicated listening time.
Her husband does the same while running; he took up listening to audiobooks because it motivated him to run longer and more often so he could get through the story.
The benefits of reading/listening while exercising
About one in three Aussies now listen to audiobooks when they exercise, according to data from Audible.
More than a third of them exercise for longer because of it, one quarter work out more often, and half experience better mood during exercise.
Data released exclusively to nine.com.au revealed both men and women reported these positive experiences at an almost identical rate, despite often having different workout routines and attitudes towards exercise.
Audiobooks are particularly popular with runners, more than a third of whom say they feel more focused on their run while listening.
Personal trainer Ben Lucas is one of them; he started listening while running to make time pass quickly and train his mind as well as his body.
“You’re out there anyway, so you may as well be learning something valuable while you do it,” he told nine.com.au.
What the experts think
Mindfulness expert Luke McLeod told nine.com.au there has even been some research into how exercise increases blood flow to the brain, which helps information retention.
Lucas devours business and personal development audiobooks like Atomic Habits by James Clear while working out, a trend which has become known as ‘personal development/PD stacking’.
The goal is to “double-up of some type of personal development like listening to an e-book, which works out the mind, while also working out the body,” McLeod said.
‘PD stacking’ is the new health optimisation trend, according to Luke McLeod. Luke McLeod
It’s all about optimising time in our busy world, which is particularly appealing to Aussies who are time-poor; like new parents trying to juggle work and a baby.
“When I’m with [my daughter], I’m trying to be present for her, so I’m not going to be listening to podcasts or anything,” Kong said.
“When I exercise, that’s my time.”

McLeod agreed that reading or listening while working out can be a great form of self-care for some Aussies.
The only pitfall is that not every workout is suited to it.
It’s hard to keep up with an audiobook or podcast if you’re trying to count reps while strength training, and there’s no way to read an e-book on a rowing machine.
“I find podcasts and audiobooks work best during longer, slower cardio sessions,” Lucas said.
“Whether it’s an easy run, walk, or long ride, you can relax into the session, tune out a little, and focus on what you’re listening to while still getting the work done.”
He also warned Aussies to stay aware of their surroundings and hazards like traffic, cyclists, other pedestrians, or uneven paths if they listen while exercising outdoors.
McLeod added that stacking habits like exercise and reading isn’t worth it if one interrupts the other.
Road testing reading at the gym
I’ve been in and out of the gym a lot over the last decade, jumping from strength training, to reformer Pilates, and other programs in between.
But my favourite way to exercise is to hop on a treadmill with my Kindle.
I rest it on the console, set a slight incline and a moderate speed and lose myself for an hour. No workout has ever felt faster or easier.

The pros: Focusing on what I’m reading takes my mind off the clock and get through an hour of cardio without getting bored or losing motivation.
Reading at the gym also helps me stay consistent because it’s one of the few places I can just switch off and focus on my book without interruptions, so I want to keep coming back.
That hour of dedicated reading time has also been great for my mental health because it forces me to slow down and focus on something completely removed from any stress in my own life.
The cons: It did take a few sessions to get used to reading while moving, but raising the brightness on my Kindle and setting it to a larger font really helped.
Those who prefer to listen don’t have to worry about any of that though; just download an audiobook and you’re good to go.
I also invested in a pair of noise-cancelling headphones to muffle the dance music that plays over my gym’s loudspeakers, which made it much easier to focus.
Reading at the gym allows Aussies like me to work on my physical and mental fitness simultaneously. Maddison Skipper
Now the only downside to reading at the gym that I sometimes hit a slump after I finish a really good book because I don’t want to hit the gym again until I find something new to read.
The verdict: It’s not for everyone, but I have found that reading at the gym has been the best way for me to stay motivated and consistent.
I feel good about taking the time to work on both my body and my mind a few times a week, and I’ve been able to check some amazing books off my ‘to be read’ list while working out.
Audiobooks make it even easier for Aussies who want to exercise without the hassle of a physical book or e-reader, or who have different accessibility needs.

The Best Fitness Trackers for Your Lifestyle, Workouts, and Goals
Like every piece of gear you wear on your body day in and day out, fitness trackers are incredibly personal. The right tracker for you should be comfortable, accurate, and tailored to your lifestyle, including your preferred workouts and health goals. Do you bike, row, or strength train? Do you run on trails for hours at a time, or do you just want a reminder to stand up every hour? Do you want to wear it on your wrist or your finger, or tuck it into your sports bra?
No matter what your needs are, there’s never been a better time to find a powerful, sophisticated tool to help optimize your workouts or jump-start your routine. We test dozens of fitness trackers every year while running, climbing, hiking, or just doing workout videos on our iPads at night, to bring you these picks.
Our top choice for most people is the Garmin Vivoactive 6 ($300), which works well with Android and iOS, but we also vouch for the latest Oura Ring 5 ($399) and the budget-friendly Google Fitbit Air ($100). For more wearables, check out our guides to the Best Smartwatches, Best Smart Rings, and Best Sleep Trackers.

Best Fitness Tracker Overall
Garmin makes some of the most accurate fitness trackers on the market, and the Vivoactive 6 is the best midrange option for most people. It strikes a solid balance between smartwatch features and fitness tracking, with support for both iPhone and Android users.
Why WIRED recommends: The Vivoactive 6 is accurate, comfortable, and packed with useful wellness features without feeling overwhelming. It uses Garmin’s proprietary algorithms to power features like Morning Report and Body Battery, which provide daily insights into your sleep, recovery, and readiness. It also has built-in satellite connectivity and GPS, so you can track outdoor workouts without bringing your phone along. There’s also incident detection, which alerts emergency contacts if it detects a serious fall.
Garmin’s biggest advantage remains its free Connect platform, which enables health and fitness tracking without requiring a subscription. The company also continues to add new software features through regular updates without putting them behind a paywall.
The trade-offs: Garmin launched Connect+, a $70-per-year subscription with extras like live tracking and access to Garmin’s AI-powered Active Intelligence. Former editor Adrienne So doesn’t think most people need it, but it’s worth noting if you’re looking for a completely subscription-free experience. The Vivoactive 6 may also feel like overkill for casual users who only want basic activity and sleep tracking.
